By translating those same classic flavors into a soup, you’ll enjoy a quicker yet just-as-delicious version of the iconic Italian dish. Trust me, one bowl won’t be enough, and your family will ask for it on repeat.

Why This Cheesy Sausage Lasagna Soup Is So Irresistible

One-pot convenience: Everything cooks in one pot, which means fewer dishes for you to clean.
Classic comfort flavors: Just like a baked lasagna, you’ve got layers of tomato richness, savory sausage, and oozing cheese.
Quick and easy: From start to finish, you’re looking at just 45 minutes!
Customizable: Swap in your favorite pasta shapes or adjust the cheese to suit your preferences.
Nutritionally balanced: With lean turkey sausage and fresh spinach, it’s indulgence with a healthy twist.

Essential Ingredients for Perfect Cheesy Sausage Lasagna Soup

Let’s spotlight a few of the key ingredients that make this easy lasagna soup recipe so special and give it its signature flavor:

Italian turkey sausage: This adds all the bold flavor of traditional sausage but lightens things up with less fat. If turkey isn’t your preference, pork sausage or even a plant-based option will work well.
Mafalda pasta: These miniature lasagna noodles are perfect for recreating that lasagna feel. Short on mafalda? Any small pasta like bowties or rotini will work too.
Tomato trifecta: A mix of tomato sauce, Italian-seasoned diced tomatoes, and chicken broth creates a rich, flavorful base. Opt for high-quality canned tomatoes for the best flavor.
Spinach: Fresh spinach stirred in at the end adds color, nutrition, and a subtle earthiness that balances the richness of the cheese and sausage.

Pro Tip: When selecting ingredients, don’t skimp on the cheese quality! Freshly shredded mozzarella and Parmesan off the block melt better and pack more flavor than pre-shredded options.

Ingredients for Cheesy Sausage Lasagna Soup

1 pound Italian turkey sausage, casings removed
2 cups chopped onions
2 cups sliced fresh mushrooms
4 cloves garlic, minced
4 cups chicken broth
1 (15-ounce) can tomato sauce
1 (14.5-ounce) can Italian-seasoned diced tomatoes
1 cup uncooked mafalda pasta
2 cups chopped fresh spinach
1 cup shredded mozzarella cheese
¼ cup Parmesan cheese
4 teaspoons thinly sliced fresh basil

Step-by-Step Cheesy Sausage Lasagna Soup Instructions

In a large pot, brown the Italian turkey sausage over medium heat, breaking it into crumbles with a wooden spoon as it cooks. This should take about 5 minutes.
Add the chopped onions, sliced mushrooms, and minced garlic to the pot. Sauté everything together until the onions are softened and the mushrooms are lightly browned, about 5 minutes.
Pour in the chicken broth, tomato sauce, and diced tomatoes (with their juices). Stir to combine and bring the mixture to a boil.
Once the soup is boiling, stir in the uncooked mafalda pasta. Turn the heat down to a simmer and cook for 10 minutes, stirring occasionally, until the pasta is nearly tender.
Stir in the chopped spinach, shredded mozzarella cheese, and grated Parmesan cheese. Let the soup simmer for another 2 minutes, allowing the spinach to wilt and the cheese to melt into the broth.
Remove the pot from the heat. Add the fresh basil, give it one last stir, and let the soup sit for 2 minutes to allow the flavors to meld together.

Expert Tips for the Best Cheesy Sausage Lasagna Soup

Use fresh ingredients: Fresh basil and spinach add brightness and flavor you won’t get from dried options.
Don’t overcook the pasta: It should be al dente and will continue to soften in the residual heat.
Make it ahead: Prepare the soup base without the pasta and cheese, refrigerate it, and add those ingredients when you’re reheating.
Storage: Store leftovers in an airtight container for up to 3 days. Reheat gently on the stovetop, adding a splash of broth if it thickens too much.
Freezing: Freeze without the pasta and cheese for up to 3 months. Thaw overnight in the fridge and finish with pasta and cheese before serving.

Delicious Cheesy Sausage Lasagna Soup Variations

Make it vegetarian: Skip the sausage and swap in a plant-based ground or hearty mushrooms like portobello for a meat-free version.
Spice it up: Add a pinch of red pepper flakes or use hot Italian sausage for a bit of heat.
Go low-carb: Replace the pasta with zucchini noodles or cauliflower rice for a lighter option.
Try different cheeses: Ricotta dolloped on top or Gruyère for a deeper, nuttier flavor.

Cheesy Sausage Lasagna Soup FAQs

Can I use another type of sausage for this recipe?

Absolutely! While Italian turkey sausage lightens things up, pork sausage, chicken sausage, or even plant-based sausage will work beautifully.

How do I make this a healthier Italian sausage soup?

Use whole-grain pasta, leaner protein like turkey or chicken sausage, and bump up the veggies by adding zucchini, carrots, or kale.

Can I make this soup ahead of time?

Yes! Prepare the soup base, store it in the fridge, and add pasta and cheese when reheating to avoid mushy noodles.

What pasta shapes work best for this quick lasagna soup with spinach?

Mafalda is my go-to, but any short pasta like fusilli, penne, or farfalle works just as well.

How can I thicken the soup?

If you want a thicker consistency, reduce the broth slightly or stir in more cheese. A cornstarch slurry will also work in a pinch.
