I stumbled upon the idea for Lasagna Soup on a night when my family was begging for my classic lasagna, but I just didn’t have the energy for all that layering and baking. The compromise? Capture every single flavor in a pot. As I browned the Italian sausage and the garlic hit the pan, that familiar, soul-warming aroma filled my kitchen. When I poured in the tomatoes and broth, the smell deepened into something truly magical. Ladling it into bowls and topping it with a dollop of ricotta, I knew I’d struck gold. It was all the rich, herby, cheesy comfort of lasagna, delivered in a fraction of the time with a spoon. It’s now our favorite cozy-night cheat.

Step-by-Step Instructions
We start by building the flavor foundation, and it all begins with the sausage. In your large pot, cook the Italian sausage over medium-high heat, breaking it up with your spoon as it browns. You want to get some nice caramelization on the meat—that’s where tons of flavor lives. Don’t drain the fat unless there’s an excessive amount; that rendered fat is gold for cooking our spices. Once the sausage is nicely browned, reduce the heat to medium and add the minced garlic. Stir it for just 30 seconds until it’s incredibly fragrant. Be careful not to burn it, as burnt garlic turns bitter fast.
Now, for the secret weapon: the seasoning blend. Sprinkle in the Italian seasoning, onion powder, steak seasoning, paprika, and black pepper directly over the sausage and garlic. Stir constantly for about one minute. This is called “blooming” the spices, and it’s a step you cannot skip. I learned this the hard way when I just dumped them into the liquid later; the soup tasted flat. Blooming them in the fat wakes up their oils and makes the entire soup taste deeply, authentically Italian. Your kitchen will smell amazing.
After the spices are bloomed, it’s time for the liquid. Pour in the tomato sauce, the diced tomatoes with their juices, the chicken broth, and the water. Give everything a good stir, scraping up any browned bits from the bottom of the pot—that’s pure flavor. Bring the soup to a lively simmer, then reduce the heat to maintain a gentle bubble. Let this simmer, uncovered, for about 10 minutes. This allows the flavors to start marrying and the broth to reduce slightly, concentrating the taste. Taste it now and add a pinch of kosher salt if needed, but remember the sausage and broth bring salt too. (See the next page below to continue…)
Finally, add the bowtie pasta. Stir it in and let the soup simmer for the time indicated on the pasta package, usually 9-11 minutes. Stir occasionally to prevent sticking. You want the pasta to be al dente—it will soften a bit more as it sits in the hot soup. I once overcooked the pasta, and it turned mushy in the bowl, which was a textural disappointment. As soon as the pasta is done, turn off the heat. The soup will be thick, rich, and perfectly hearty. Now, it’s time for the signature lasagna touch.
Pro Tips for Best Results
My number one tip is about the pasta. I’ve tested this three different ways: cooking the pasta directly in the soup (best for immediate serving), cooking it separately and adding it per bowl (best for leftovers), and using a different shape. Cooking it in the soup gives the broth a lovely, slightly starchy thickness and lets the pasta absorb all the flavor. However, if you plan on having leftovers, cook the pasta separately and store it apart from the soup to prevent it from bloating and absorbing all the broth overnight.
The second tip is all about layering the flavors. That minute of blooming the dried spices in the sausage fat is non-negotiable. It transforms them from dusty to dynamic. Also, using both tomato sauce and diced tomatoes with herbs gives you the perfect texture—creamy from the sauce and chunky from the tomatoes. Don’t substitute plain diced tomatoes; the Italian herbs in the can are a built-in flavor boost that makes a big difference.
Finally, don’t skip the finishing toppings. They are what truly make it “lasagna” soup. The cool, creamy dollop of ricotta cheese melting into the hot soup is essential. It mimics the rich ricotta layer in traditional lasagna. A generous sprinkle of Parmesan cheese adds the salty, umami punch, and the fresh parsley gives a necessary pop of color and freshness that cuts through the richness. I serve the toppings in bowls on the table so everyone can build their perfect bowl.
Common Mistakes to Avoid
The first mistake I made was using ground beef instead of Italian sausage. I thought I could shortcut with what I had. The soup was fine, but it was missing that distinctive, fennel-spiced, savory depth that makes it taste like lasagna. Italian sausage is the soul of this dish. If you want a lighter version, use mild Italian turkey sausage, but don’t skip it. The seasoning packed into the sausage is irreplaceable. (See the next page below to continue…)
Another error is not adjusting the liquid. All chicken broths and pasta brands are different. If your soup seems too thick after adding the pasta, don’t be afraid to add an extra ½ cup of water or broth. Conversely, if it seems too thin after the pasta is cooked, let it simmer uncovered for a few extra minutes to reduce. The perfect consistency is like a very hearty, chunky stew—thick enough to coat the pasta but still brothy enough to be soup.
Overcooking the pasta is a common pitfall, especially if you plan on having leftovers. Pasta continues to cook and soften in the hot liquid even off the heat. I aim to cook it to just barely al dente, then immediately ladle it into bowls. If you know you’ll have leftovers, cook the pasta separately to al dente, rinse it with cool water to stop the cooking, and store it separately. Then, add a portion to each bowl of reheated soup. This keeps the texture perfect for days.
Finally, skimping on the toppings is a disservice to the experience. This isn’t just tomato soup with pasta. The ricotta cheese is not optional; it’s what makes it lasagna soup. Letting everyone add their own allows the cool ricotta to mix with the hot soup, creating little creamy pockets in every bite, just like the layered cheese in baked lasagna. The Parmesan and parsley are the final, essential flavor notes. Embrace the full assembly!
Serving Suggestions
I love serving this soup in large, wide bowls with all the toppings arranged in the center of the table. I put the ricotta in a small bowl with a spoon, the Parmesan in a shaker, and the chopped parsley in a little dish. Alongside, I always serve a loaf of warm, crusty garlic bread or a batch of soft, buttery breadsticks. Dipping that bread into the rich, tomatoey broth is an absolute essential part of the meal.
For a more complete Italian feast, I’ll pair it with a simple, crisp Caesar salad or an antipasto plate with marinated olives and meats. The soup is so hearty that a light, refreshing salad is the perfect balance. For a casual family movie night, we often just have big bowls of soup and garlic bread—it’s the ultimate cozy, satisfying meal that requires nothing else.
When I’m serving this for a crowd, like during football season, I keep it simple and stress-free. I transfer the soup to a slow cooker on the “warm” setting and let everyone serve themselves buffet-style. The toppings are set up next to it. It’s a guaranteed crowd-pleaser that feels special but lets me enjoy the party, not slave in the kitchen.
Variations & Customizations
This soup is wonderfully adaptable. If you love vegetables, feel free to add them when you bloom the spices. A diced onion and a cup of sliced mushrooms sautéed with the sausage add fantastic texture and earthiness. A handful of chopped spinach or kale stirred in during the last two minutes of cooking wilts down perfectly and adds a nutritional boost. For a “vegetable lasagna” vibe, you can use plant-based Italian sausage and vegetable broth.
You can easily change up the pasta shape. While bowties are fun and hold the broth well, other great options are mafalda (mini lasagna noodles), rotini, or even broken-up lasagna noodles. Just adjust the cooking time accordingly. For a gluten-free version, use your favorite gluten-free pasta and be sure to check that your sausage and seasonings are gluten-free as well.
For a richer, creamier soup, stir in a half-cup of heavy cream or a few tablespoons of cream cheese along with the ricotta at the end. For a meatier version, add a half-pound of lean ground beef with the sausage. If you like a touch of sweetness to balance the tomatoes, a teaspoon of sugar can be added with the broth. The basic framework is incredibly forgiving.
How to Store, Freeze & Reheat
Leftovers can be stored in an airtight container in the refrigerator for 3-4 days. Be aware that the pasta will continue to absorb the broth, so it will become much thicker. When reheating on the stovetop, add a splash of water, broth, or even a bit of extra tomato sauce to loosen it back to soup consistency. Reheat gently over medium-low heat.
This soup freezes beautifully, but with one important rule: freeze the soup base without the pasta. The pasta will become mushy and grainy when frozen and thawed. After cooking the soup, let the broth and sausage mixture cool completely, then portion it into freezer-safe bags or containers. It will keep for up to 3 months.
To serve, thaw the soup base overnight in the refrigerator. Reheat it in a pot on the stove. While it’s reheating, cook a fresh batch of bowtie pasta separately. Ladle the hot soup over the cooked pasta in each bowl and add your fresh toppings. This method ensures every bowl tastes as vibrant and texturally perfect as the first.

This Lasagna Soup is more than just a recipe; it’s a brilliant, time-saving hack that delivers maximum comfort with minimal effort. It’s the answer to lasagna cravings any night of the week and has become a beloved staple in my home.
