I was up to my elbows in potting soil, trying to convince a basil plant to survive another week, when my accountantโ€”a man Iโ€™d only ever seen in a tie and wire-rimmed glassesโ€”leaned over the fence. โ€œYou know what youโ€™re missing?โ€ he said, wiping dirt off his hands. โ€œA pot of that lasagna soup my wife makes. Itโ€™s all the good stuff, none of the layering drama.โ€ I blinked at him. This was the same guy who once sent me a color-coded spreadsheet for my quarterly taxes. But there he was, describing how he browns Italian sausage in a single pot and lets it all bubble together until the kitchen smells like Sunday dinner. I scribbled his instructions on the back of a seed packet, honestly not expecting much. But let me tell youโ€”that first spoonful of creamy, sausage-studded broth with tender pasta and a dollop of ricotta? I havenโ€™t made a traditional lasagna since. Maybe youโ€™ve been there, staring at a lasagna recipe and wondering if you really have the patience for all those layers. This soup is the answer you didnโ€™t know you needed.

This Creamy One-Pot Lasagna Soup with Italian Sausage and Ricotta takes everything we love about the classic baked dishโ€”the rich tomato sauce, the savory meat, the creamy cheeseโ€”and turns it into a weeknight-friendly meal that comes together in under 45 minutes. No boiling pasta separately, no scrubbing a dozen dishes, and definitely no stressing over perfectly even layers. Itโ€™s comfort food that actually fits into a busy life, and it tastes like you spent hours in the kitchen.

Why Youโ€™ll Love This Recipe

Iโ€™ve tested this soup more times than I care to admit, tweaking the broth ratio and the sausage-to-pasta balance until it was just right. Hereโ€™s why I keep coming back to itโ€”and why I think you will too.

  • Quick & Easy: From stovetop to bowl in about 40 minutes. No pre-boiling pasta, no complicated steps, and only one pot to wash when youโ€™re done. Perfect for those nights when you want something hearty without the cleanup.
  • Simple Ingredients: You probably already have most of what you need in your pantryโ€”canned tomatoes, chicken broth, dried herbs, garlic. The fresh sausage and ricotta are the only special trip you might need to make, and theyโ€™re worth it.
  • Perfect for Busy Weeknights: This is the kind of meal that saves you on a Tuesday when everyoneโ€™s hungry and youโ€™re out of ideas. Itโ€™s also great for meal prepโ€”the flavors actually get better overnight.
  • Crowd-Pleaser: Iโ€™ve served this to picky kids, skeptical in-laws, and friends who claim they donโ€™t like soup. Every single person went back for seconds. Itโ€™s that good.
  • Unbelievably Delicious: The secret is in the finishโ€”stirring in a splash of heavy cream and a generous dollop of ricotta right at the end. It transforms the broth into something velvety and luxurious, without being heavy.

What makes this version different from all the other lasagna soup recipes out there? Itโ€™s the balance. The sausage is browned until deeply caramelized, the broth is simmered with a Parmesan rind for extra savory depth, and the ricotta is swirled in at the very end so it stays creamy and distinct. Itโ€™s not just another soupโ€”itโ€™s the soup that makes you close your eyes after the first bite and forget about the long day you just had.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, and the few fresh items are easy to find at any grocery store.

  • Italian Sausage (1 lb, casings removed): I prefer mild Italian sausage for a family-friendly heat level, but hot Italian sausage works beautifully if you like a kick. Look for sausage with a good fat contentโ€”lean sausage wonโ€™t give you the same rich flavor. I like Johnsonville or a local butcherโ€™s house-made blend.
  • Yellow Onion (1 medium, diced): A sweet yellow onion forms the aromatic base. You can use a white onion in a pinch, but yellow adds a subtle sweetness that balances the acidity of the tomatoes.
  • Garlic (4 cloves, minced): Fresh garlic is non-negotiable here. Pre-minced jarred garlic will work, but youโ€™ll lose some of that punchy aroma. I always add an extra clove because Iโ€™m greedy.
  • Crushed Tomatoes (1 can, 28 oz): Use good-quality crushed tomatoes for the best flavor. San Marzano tomatoes are my go-toโ€”theyโ€™re sweeter and less acidic. If you only have whole peeled tomatoes, crush them by hand before adding.
  • Chicken Broth (4 cups): Low-sodium broth is essential so you can control the salt level. Vegetable broth works fine for a lighter flavor, but chicken broth adds more savory depth. I use Swanson or Kitchen Basics.
  • Dried Oregano (1 tsp): Oregano is the classic lasagna herb. It adds a slightly peppery, earthy note that pairs perfectly with the sausage. Donโ€™t skip itโ€”itโ€™s part of the soul of this dish.
  • Dried Basil (1 tsp): Basil brings a hint of sweetness and a floral aroma. If you have fresh basil, stir in a handful of chopped leaves at the end for a bright finish.
  • Red Pepper Flakes (ยฝ tsp, optional): A pinch of heat wakes up the whole dish. Add more if you like it spicy, or leave it out entirely for a milder soup.
  • Mafalda Pasta (8 oz): These little ribbon-like noodles with ruffled edges are my favorite for lasagna soupโ€”they catch the broth in their folds. If you canโ€™t find mafalda, broken lasagna sheets, fusilli, or farfalle work great. Cook them directly in the soup for maximum flavor absorption.
  • Heavy Cream (ยฝ cup): This is what makes the soup creamy without being too rich. Half-and-half works in a pinch, but the soup wonโ€™t be quite as luxurious. For a dairy-free option, use full-fat coconut cream.
  • Whole Milk Ricotta (1 cup): Look for a creamy, full-fat ricottaโ€”Galbani and Calabro are my trusted brands. The texture should be smooth, not grainy. Avoid part-skim ricotta, which can turn watery when stirred in.
  • Fresh Parmesan (ยฝ cup, grated): A good Parmesan adds nutty, salty notes that tie everything together. Always grate it fresh from a blockโ€”pre-grated stuff has anti-caking agents that prevent it from melting smoothly.
  • Fresh Parsley (ยผ cup, chopped): A sprinkle of fresh parsley at the end adds color and a fresh, slightly peppery finish. Flat-leaf parsley is best, but curly works too.
  • Salt and Black Pepper (to taste): Season as you go, tasting and adjusting. The sausage and Parmesan are both salty, so go easy on the salt at the beginning.

Equipment Needed

You donโ€™t need a fancy kitchen to make this soupโ€”just a few basic tools. Hereโ€™s what youโ€™ll need:

  • Large Dutch Oven or Heavy-Bottomed Pot (5-6 quart): This is your workhorse. A Dutch oven distributes heat evenly and has enough room for all the ingredients without splattering. If you donโ€™t have one, any large, deep pot with a heavy bottom will workโ€”just keep an eye on the heat to prevent sticking.
  • Wooden Spoon or Silicone Spatula: Youโ€™ll use this to break up the sausage and stir the soup. A wooden spoon wonโ€™t scratch your pot and feels nice in the hand.
  • Chefโ€™s Knife and Cutting Board: For dicing the onion and mincing the garlic. A sharp knife makes the prep go faster and safer.
  • Measuring Cups and Spoons: Accurate measurements matter, especially for the broth and cream. I use glass measuring cups for liquids and metal spoons for dry ingredients.
  • Box Grater or Microplane: For grating fresh Parmesan. A Microplane gives you fine, fluffy shreds that melt instantly into the hot soup.
  • Ladle: For serving. A deep ladle with a wide mouth is perfect for getting both broth and pasta into each bowl.

If you donโ€™t have a Dutch oven, no worriesโ€”a large stainless steel pot works fine. Just be careful not to let the soup scorch on the bottom. And if you donโ€™t have a Microplane, a vegetable peeler works in a pinch to shave Parmesan ribbons over the finished soup.

Preparation Method

lasagna soup preparation steps

Letโ€™s get cooking. This method is straightforward, but Iโ€™ve included all the little details that make the difference between a good soup and a great one.

  1. Brown the Sausage (5 minutes): Heat your Dutch oven over medium-high heat. Add the Italian sausage (casings removed) and break it apart with a wooden spoon. Cook, stirring occasionally, until deeply browned and crumblyโ€”about 5-7 minutes. Donโ€™t rush this step; the caramelized bits on the bottom of the pot are pure flavor. Use a slotted spoon to transfer the sausage to a plate, leaving about 2 tablespoons of rendered fat in the pot. If your sausage is lean, add a drizzle of olive oil.
  2. Sautรฉ the Aromatics (4 minutes): Reduce the heat to medium. Add the diced onion to the pot and cook, stirring, until softened and translucentโ€”about 3 minutes. Scrape up any browned bits from the bottom as you stir. Add the minced garlic and cook for 30 seconds more, until fragrant. Be careful not to let the garlic burnโ€”it turns bitter fast.
  3. Build the Broth (5 minutes): Pour in the crushed tomatoes and chicken broth, stirring to combine. Add the dried oregano, dried basil, and red pepper flakes (if using). Bring the mixture to a lively simmerโ€”you should see small bubbles breaking the surface, not a rolling boil. Season with a pinch of salt and a few grinds of black pepper. Let it simmer for 5 minutes to meld the flavors. If you have a Parmesan rind, drop it in nowโ€”it adds incredible savory depth.
  4. Cook the Pasta (10-12 minutes): Stir in the mafalda pasta (or your chosen shape). Return the soup to a gentle simmer and cook, stirring occasionally, until the pasta is tender but still has a slight bite (al dente). Check the package instructions for timingโ€”fresh pasta cooks faster than dried. If the soup gets too thick as the pasta absorbs liquid, add a splash of hot water or extra broth. Return the browned sausage to the pot during the last 2 minutes of cooking so it heats through.
  5. Make It Creamy (2 minutes): Remove the pot from the heat. Fish out the Parmesan rind if you used one. Stir in the heavy cream until the broth turns a beautiful, velvety pink-orange. Then, dollop the ricotta over the top in generous spoonfulsโ€”donโ€™t stir it in completely. You want creamy pockets of cheese in every bowl. Sprinkle the grated Parmesan over the surface and give it one gentle stir to incorporate.
  6. Rest and Serve (5 minutes): Let the soup sit off the heat for 5 minutes. This allows the flavors to settle and the pasta to absorb a little more broth without getting mushy. Ladle into bowls, making sure each serving gets some of the ricotta and Parmesan. Finish with a sprinkle of fresh parsley and an extra grating of black pepper. Serve hot, with crusty bread or garlic bread on the side for dipping.

Pro Tip: If youโ€™re meal-prepping, cook the pasta separately and add it to individual bowls when serving. This prevents the pasta from soaking up all the broth overnight and turning into a mushy mess. The soup base (without pasta) keeps beautifully in the fridge for up to 4 days.

Cooking Tips & Techniques

Over the years, Iโ€™ve made this soup at least two dozen times, and Iโ€™ve learned a few things the hard way. Here are my best tips to make sure yours turns out perfect every time.

  • Donโ€™t Skip the Browning: I once tried to save time by not browning the sausage thoroughly, and the soup was bland. Those deep, caramelized bits stuck to the bottom of the pot are the foundation of the flavor. Let the sausage get good and darkโ€”itโ€™s worth the extra two minutes.
  • Watch the Pasta: Pasta continues to absorb liquid even after you take the pot off the heat. If youโ€™re serving the soup right away, cook the pasta until itโ€™s just al denteโ€”it will soften a little more in the hot broth. If youโ€™re making it ahead, undercook the pasta by a minute or two, or cook it separately as I mentioned above.
  • Season as You Go: Donโ€™t wait until the end to add all the salt. Season the sausage as it browns, then taste the broth after adding the tomatoes and adjust. The Parmesan and ricotta both add saltiness, so go easy at firstโ€”you can always add more at the table.
  • The Cream Trick: Adding the cream off the heat prevents it from curdling. High heat can cause the dairy to separate, leaving you with a grainy soup. Stir it in gently once the pot is off the burner, and youโ€™ll get a silky-smooth finish every time.
  • Multitasking Strategy: While the sausage browns, dice your onion and mince the garlic. While the broth simmers, grate the Parmesan and chop the parsley. This way, everything comes together without a last-minute scramble.

One of my biggest failures? I once added the ricotta too early and stirred it in completely. The soup turned into a weird, watery mess with little white flecks floating around. Now I know: dollop it on top and let people stir it in themselves. Itโ€™s prettier and tastes better.

Variations & Adaptations

This soup is wonderfully flexible. Here are a few ways to make it your own, based on what Iโ€™ve tried and loved.

  • Vegetarian Version: Swap the Italian sausage for a plant-based sausage (I like Beyond Meatโ€™s hot Italian style) or use 2 cups of finely chopped mushrooms sautรฉed with garlic and herbs. Use vegetable broth instead of chicken broth. The mushrooms add that same savory, umami depth.
  • Gluten-Free Adaptation: Use your favorite gluten-free pastaโ€”brown rice fusilli or chickpea rotini work well. Cook it separately according to package directions and add it to individual bowls, since gluten-free pasta tends to get mushy if left in the broth too long. The rest of the recipe is naturally gluten-free.
  • Spicy Kick: Use hot Italian sausage instead of mild, and double the red pepper flakes. For extra heat, stir in a tablespoon of Calabrian chili paste or a pinch of cayenne pepper with the tomatoes. I made this version for a Super Bowl party, and it disappeared in ten minutes.
  • Dairy-Free Option: Replace the heavy cream with full-fat coconut cream (the thick part from a can of coconut milk). Use a dairy-free ricottaโ€”Kite Hill makes a good almond-based oneโ€”or simply skip the ricotta and add an extra dollop of coconut cream. The soup will have a slight coconut undertone, which pairs surprisingly well with the Italian flavors.
  • Seasonal Twist: In the summer, stir in a handful of fresh spinach or chopped zucchini during the last 5 minutes of cooking. In the fall, add roasted butternut squash cubes along with the pasta. Itโ€™s a great way to use up whatever vegetables you have on hand.

Serving & Storage Suggestions

This soup is at its best served hot, straight from the pot, but itโ€™s also forgiving enough to be made ahead. Hereโ€™s how to serve and store it like a pro.

  • Serving Temperature: Serve the soup piping hot, with an extra drizzle of olive oil and a crack of black pepper over each bowl. The ricotta should be slightly melted but still holding its shapeโ€”that contrast of warm broth and cool, creamy cheese is the best part.
  • What to Serve With It: A chunk of crusty bread or garlic bread is essential for sopping up every last drop of broth. A simple green salad with lemon vinaigrette cuts through the richness beautifully. For drinks, a light red wine like Chianti or a cold Italian beer works wonderfully.
  • Refrigerating: Store leftovers in an airtight container in the refrigerator for up to 4 days. The pasta will absorb more liquid as it sits, so the soup will thicken. When reheating, add a splash of broth or water to loosen it up. The flavors actually meld and deepen overnightโ€”I often think day-two soup is even better.
  • Freezing: This soup freezes well, but with one caveat: freeze it without the pasta. Let the soup base cool completely, then transfer it to a freezer-safe container. It will keep for up to 3 months. When youโ€™re ready to eat, thaw it in the refrigerator overnight, reheat it on the stove, and cook fresh pasta directly in the soup. The cream and ricotta may separate slightly after freezing, but a vigorous stir brings it back together.
  • Reheating: Reheat individual portions in the microwave for 2-3 minutes, stirring halfway through. For larger batches, reheat on the stovetop over medium-low heat, adding a splash of broth or water if needed. Avoid boiling the soup after the cream has been addedโ€”gentle heat is your friend here.

Nutritional Information & Benefits

While this soup feels indulgent, itโ€™s surprisingly balanced. Hereโ€™s a rough estimate per serving (based on 6 servings):

  • Calories: ~480 kcal
  • Protein: 24g
  • Fat: 28g
  • Carbohydrates: 35g
  • Fiber: 4g
  • Sugar: 8g
  • Sodium: 890mg (varies based on broth and sausage)

This soup is a good source of protein from the sausage and ricotta, and the tomatoes provide a healthy dose of lycopene, an antioxidant linked to heart health. The calcium from the ricotta and Parmesan supports bone health, and the garlic and onions offer anti-inflammatory properties. If youโ€™re watching your carb intake, you can reduce the pasta to 4 ounces or use a low-carb pasta alternative like chickpea or lentil pasta. For a lower-sodium version, use no-salt-added broth and look for low-sodium sausageโ€”just be sure to season well with herbs and spices to compensate.

I love that this soup feels like a treat but doesnโ€™t leave me feeling sluggish afterward. Itโ€™s the kind of meal that satisfies a craving for comfort food without the guilt, and thatโ€™s a win in my book.

Conclusion

This Creamy One-Pot Lasagna Soup with Italian Sausage and Ricotta is the kind of recipe that earns a permanent spot in your dinner rotation. Itโ€™s quick enough for a busy weeknight, impressive enough for company, and comforting enough to make you forget about all the other things on your to-do list. I love how it captures everything I adore about lasagnaโ€”the rich tomato broth, the savory sausage, the creamy pockets of cheeseโ€”without the hours of layering and baking.

Frequently Asked Questions

Can I use ground beef instead of Italian sausage?

Absolutely. Ground beef works, but youโ€™ll lose some of the fennel and herb flavors that make this soup taste like lasagna. To compensate, add an extra teaspoon of dried oregano and a pinch of fennel seeds to the broth. Iโ€™ve made it with ground turkey too, and itโ€™s still deliciousโ€”just a little leaner.

My soup is too thick. How do I fix it?

This usually happens when the pasta absorbs too much liquid. Simply stir in a splash of hot water or chicken broth until it reaches your desired consistency. If youโ€™re reheating leftovers, always have a little extra broth on hand to thin it out. The soup should be brothy but hearty, not like a stew.

Can I make this in a slow cooker or Instant Pot?

Yes, with a few adjustments. For a slow cooker: brown the sausage and sautรฉ the aromatics on the stovetop first, then transfer everything except the pasta, cream, and ricotta to the slow cooker. Cook on low for 4-6 hours. Stir in the pasta 30 minutes before serving, then finish with the cream and ricotta. For an Instant Pot: use the sautรฉ function to brown the sausage and aromatics, then add the broth, tomatoes, and herbs. Pressure cook on high for 5 minutes, quick release, then stir in the pasta and cook on sautรฉ until tender. Finish with cream and ricotta.

Whatโ€™s the best pasta shape for lasagna soup?

Mafalda (mini lasagna noodles) is my top choice because it catches the broth in its ruffled edges. Broken lasagna sheets are a close secondโ€”just snap them into bite-sized pieces before adding. Fusilli, farfalle, or even ditalini all work great. Avoid very small pasta like orzo, which can turn mushy quickly.

Can I skip the heavy cream to make it lighter?

Yes. For a lighter version, skip the cream entirely and just use the ricotta for creaminess. The soup will still be delicious, just not as rich. You can also use half-and-half or whole milk, but the texture wonโ€™t be as velvety. If youโ€™re dairy-free, coconut cream is a fantastic substituteโ€”it adds richness without any dairy.

Creamy One-Pot Lasagna Soup with Easy Italian Sausage


  • Author: Sarah Wasserman
  • Total Time: 40 minutes
  • Yield: 6 servings 1x

Description

This creamy one-pot lasagna soup with Italian sausage and ricotta takes everything we love about the classic baked dish and turns it into a weeknight-friendly meal that comes together in under 45 minutes. No boiling pasta separately, no scrubbing a dozen dishes, and definitely no stressing over perfectly even layers.


Ingredients

Scale
  • 1 lb Italian sausage, casings removed
  • 1 medium yellow onion, diced
  • 4 cloves garlic, minced
  • 1 can (28 oz) crushed tomatoes
  • 4 cups low-sodium chicken broth
  • 1 tsp dried oregano
  • 1 tsp dried basil
  • ยฝ tsp red pepper flakes (optional)
  • 8 oz mafalda pasta (or broken lasagna sheets, fusilli, farfalle)
  • ยฝ cup heavy cream
  • 1 cup whole milk ricotta
  • ยฝ cup fresh Parmesan, grated
  • ยผ cup fresh parsley, chopped
  • Salt and black pepper to taste

Instructions

  1. Brown the Sausage (5 minutes): Heat your Dutch oven over medium-high heat. Add the Italian sausage (casings removed) and break it apart with a wooden spoon. Cook, stirring occasionally, until deeply browned and crumblyโ€”about 5-7 minutes. Use a slotted spoon to transfer the sausage to a plate, leaving about 2 tablespoons of rendered fat in the pot.
  2. Sautรฉ the Aromatics (4 minutes): Reduce the heat to medium. Add the diced onion to the pot and cook, stirring, until softened and translucentโ€”about 3 minutes. Scrape up any browned bits from the bottom as you stir. Add the minced garlic and cook for 30 seconds more, until fragrant.
  3. Build the Broth (5 minutes): Pour in the crushed tomatoes and chicken broth, stirring to combine. Add the dried oregano, dried basil, and red pepper flakes (if using). Bring the mixture to a lively simmer. Season with a pinch of salt and a few grinds of black pepper. Let it simmer for 5 minutes to meld the flavors. If you have a Parmesan rind, drop it in now.
  4. Cook the Pasta (10-12 minutes): Stir in the mafalda pasta. Return the soup to a gentle simmer and cook, stirring occasionally, until the pasta is tender but still has a slight bite (al dente). If the soup gets too thick, add a splash of hot water or extra broth. Return the browned sausage to the pot during the last 2 minutes of cooking.
  5. Make It Creamy (2 minutes): Remove the pot from the heat. Fish out the Parmesan rind if you used one. Stir in the heavy cream until the broth turns a beautiful, velvety pink-orange. Then, dollop the ricotta over the top in generous spoonfulsโ€”donโ€™t stir it in completely. Sprinkle the grated Parmesan over the surface and give it one gentle stir to incorporate.
  6. Rest and Serve (5 minutes): Let the soup sit off the heat for 5 minutes. Ladle into bowls, making sure each serving gets some of the ricotta and Parmesan. Finish with a sprinkle of fresh parsley and an extra grating of black pepper. Serve hot, with crusty bread or garlic bread on the side for dipping.

Notes

If you’re meal-prepping, cook the pasta separately and add it to individual bowls when serving to prevent it from soaking up all the broth overnight. The soup base (without pasta) keeps beautifully in the fridge for up to 4 days. For a vegetarian version, swap the Italian sausage for plant-based sausage or mushrooms and use vegetable broth. For a gluten-free adaptation, use gluten-free pasta and cook it separately.
