Picture this: a chilly evening, the aroma of garlic and basil drifting through your kitchen, and a steaming bowl of soup that tastes just like your favorite lasagna—but without the layering, baking, or waiting. That's what this Comfort Food Lasagna Soup is all about. It's the love child of a hearty Italian soup and the classic baked lasagna, born from a spontaneous craving and a lack of time.

I've taken all the soulful components of lasagna—savory sausage, rich marinara, tender noodles, and a creamy cheese blend—and transformed them into a spoonable, soul-warming meal. It's an adventure in a bowl, where every spoonful brings a burst of flavor. And the best part? It all comes together in one pot, so you can spend less time cleaning and more time savoring.
Why You'll Love This Recipe
About the Ingredients
1 lb (450g) Italian sausage, casings removed
Use sweet or hot Italian sausage for flavor. Substitute with ground beef or turkey plus 1 tsp fennel seeds for a similar taste.
1 medium onion, diced
Yellow or sweet onion works best. If you're in a pinch, use 1 cup frozen diced onion, no need to thaw.
3 cloves garlic, minced
Fresh garlic gives the best punch. In a hurry? Use 1 teaspoon garlic powder mixed with the broth.
4 cups (960ml) low-sodium chicken broth
Chicken broth adds savory depth. For a vegetarian version, use vegetable broth and skip the sausage (add extra mushrooms).
1 can (28 oz / 800g) crushed tomatoes
Crushed tomatoes give a thick, rich base. If you only have diced tomatoes, blend them quickly for a smoother texture.
1 can (14.5 oz / 410g) diced tomatoes, undrained
Adds texture and brightness. Fire-roasted diced tomatoes add a smoky twist—try them for extra depth.
2 teaspoons dried Italian seasoning
A blend of oregano, basil, and thyme. Make your own with 1 tsp each of dried oregano and basil plus 1/2 tsp thyme.
1/2 teaspoon red pepper flakes (optional)
For a gentle heat. Omit if you prefer mild, or add more if you like it spicy.
8 oz (225g) lasagna noodles, broken into 2-inch pieces
Use gluten-free lasagna noodles if needed—they work just as well. No lasagna sheets? Any short pasta like penne or rotini works.
1/2 cup (50g) grated Parmesan cheese
Freshly grated melts better and tastes sharper. Pre-grated is fine, but add a little extra for flavor.
1 cup (240g) ricotta cheese
Whole-milk ricotta is creamiest. For a lighter option, use part-skim; cottage cheese blended smooth is a good swap.
2 cups (170g) shredded mozzarella cheese
Use low-moisture mozzarella for best melting. You can also use a pizza blend if that's what you have.
Fresh basil leaves, for garnish
Optional but adds a fresh pop. If you don't have fresh, a pinch of dried basil in the soup works.
Tips & Tricks
Don't overcook the noodles
Cook them just until al dente in the soup, because they'll continue to soften as they sit. If you're making ahead, slightly undercook them and add a splash of broth when reheating.
Use a heavy-bottomed pot
A Dutch oven or heavy pot distributes heat evenly and prevents scorching. If you don't have one, stir frequently to avoid sticking.
Balance the acidity
If the soup tastes too tangy, add a pinch of sugar or a pat of butter to mellow it out. The cheese also helps tame acidity.
Pro Tips
Step-by-Step Instructions
1. Brown the sausage
In a large Dutch oven or pot over medium-high heat (350°F / 175°C), cook the Italian sausage, breaking it into crumbles with a spoon, until browned and cooked through, about 6-8 minutes. Remove with a slotted spoon and set aside, leaving about 1 tablespoon of drippings in the pot.
2. Sauté aromatics
Reduce heat to medium (300°F / 150°C). Add the diced onion and cook until translucent, about 4-5 minutes. Stir in the garlic and cook for 30 seconds until fragrant, being careful not to burn it.
3. Add liquids and seasonings
Pour in the chicken broth, crushed tomatoes, diced tomatoes, Italian seasoning, and red pepper flakes (if using). Stir well, scraping up any browned bits from the bottom. Bring the mixture to a boil over high heat (375°F / 190°C).
4. Simmer the soup base
Reduce heat to low (250°F / 120°C) and let the soup simmer, uncovered, for 15 minutes to meld the flavors. The liquid should be gently bubbling; you'll see tiny bubbles breaking the surface.
5. Cook the noodles
Add the broken lasagna noodles and the cooked sausage back into the pot. Stir well, then continue to simmer for about 10-12 minutes, stirring occasionally, until the noodles are al dente (tender but still slightly firm to the bite).
6. Stir in the cheeses
Remove the pot from heat. Stir in the Parmesan cheese until melted. Drop spoonfuls of ricotta over the top, then sprinkle with the mozzarella. Cover the pot and let it sit for 3-5 minutes, allowing the cheese to melt and become gooey.
7. Garnish and serve
Ladle the soup into bowls, making sure each serving gets a generous swirl of ricotta and melted mozzarella. Garnish with fresh basil leaves if desired. Serve hot with crusty bread on the side.
Delicious Variations
Vegetarian Mushroom Lasagna Soup
Swap the sausage for 2 cups (about 200g) sliced cremini mushrooms, sautéed until golden, and use vegetable broth. Add a handful of spinach at the end for extra greens.
Spicy Sausage and Kale Lasagna Soup
Use hot Italian sausage and add 2 cups chopped kale in the last 5 minutes of cooking until wilted. The slight bitterness of kale pairs beautifully with the spicy sausage.
Chicken and Pesto Lasagna Soup
Replace sausage with diced cooked chicken breast and stir in 2 tablespoons of pesto right before serving. Use basil pesto for a fresh, herby kick.
How to Store Comfort Food Lasagna Soup
Refrigerator
Store in an airtight container in the fridge for up to 4 days. The noodles will absorb liquid, so you may need to add a splash of broth or water when reheating.
Freezer
Freeze in a freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating. Note that the noodles will become softer after freezing, so consider undercooking them slightly if you plan to freeze.
Reheating
Reheat in a pot over medium heat (300°F / 150°C) until bubbling, about 5-7 minutes. Or microwave individual portions in 1-minute intervals, stirring in between, until hot.
Frequently Asked Questions
Q: Can I make lasagna soup in a slow cooker?
Yes, you can! Brown the sausage and sauté the aromatics first, then transfer everything except the noodles and cheeses to a slow cooker. Cook on low for 4-6 hours or high for 2-3 hours. Add the noodles 20-30 minutes before serving, then stir in the cheeses just before serving.
Q: How do I keep the noodles from getting mushy?
Cook the noodles only until al dente in the soup, and remember they'll continue to cook as the soup sits. If you're reheating leftovers, add a bit of broth to restore the liquid and avoid overcooking the noodles further.
Q: Can I use no-boil lasagna noodles instead of regular?
Yes, no-boil noodles work well. Break them into pieces and add them to the soup; they will cook in the liquid in about 10-12 minutes. Just be sure to stir occasionally so they don't stick together.
Q: What can I use instead of Italian sausage?
Ground beef, ground turkey, or even a plant-based sausage crumble are excellent substitutes. If using ground meat, add 1 teaspoon of fennel seeds and 1/2 teaspoon of dried oregano to mimic the sausage flavor.
Q: Is this soup gluten-free?
It can easily be made gluten-free by using gluten-free lasagna noodles or your favorite gluten-free pasta. Also, check that your broth and tomatoes are certified gluten-free if you have celiac disease.
