Key Ingredients & Substitutions
Italian Sausage: This adds great flavor, but if you’re looking for a lighter option, you could use ground turkey or chicken. You can also use vegetarian sausage if you want a meatless version.
Garlic: Fresh garlic gives the best flavor, but if you’re in a pinch, garlic powder can be a quick substitute. Just use about 1/8 teaspoon for every clove.
No-Boil Lasagna Noodles: These make the prep easy, but if you can’t find them, regular lasagna noodles work too. Just cook them according to package directions before adding to the soup.
Alfredo Sauce: While homemade is often tastier, store-bought is convenient. Consider using a low-fat version if you want to lighten things up.
Fresh Spinach: Don’t hesitate to swap spinach for other greens, like kale or Swiss chard, which can add a different flavor and texture!
How Do You Get Your Soup to Be Extra Creamy?
The secret to a rich, creamy lasagna soup is all about properly incorporating your liquids and cheeses. Here’s how to achieve that creamy texture:
- Start by cooking the sausage well to render out the fat, which contributes to the soup’s base.
- When you add the broth and milk, make sure they’re at room temperature to avoid shocking the pot. This keeps the soup from separating.
- Stir in the Alfredo sauce gradually, combining it thoroughly with the broth and sausage mix before adding the noodles.
- Finally, the Parmesan cheese adds a beautiful creaminess when it melts in, so stir gently to incorporate it without clumping.
Letting the soup sit for a few minutes before serving allows everything to meld together nicely!

This hearty soup takes about 15 minutes of preparation and about 20 minutes of cooking time, totaling around 35 minutes from start to finish. You’ll have a delicious, creamy meal ready in no time!
Step-by-Step Instructions:
1. Brown the Sausage:
In a large Dutch oven or heavy pot, heat a drizzle of olive oil over medium heat. Once hot, add the Italian sausage, breaking it up with a spoon. Cook for about 6-8 minutes until browned and fully cooked through. If there’s excess grease, carefully drain it from the pot.
2. Add Garlic:
Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant. This will give your soup a wonderful flavor base.
3. Combine Broth and Sauces:
Next, pour in the chicken broth and milk, then stir in the Alfredo sauce and drained diced tomatoes. Bring the mixture to a gentle boil while stirring occasionally.
4. Cook the Noodles:
Add the broken lasagna noodles to the pot and give it a good stir. Reduce the heat to medium-low and let the soup simmer uncovered for about 10-12 minutes, stirring occasionally, until the noodles are nice and tender.
5. Add Spinach:
Gently fold in the fresh spinach leaves and let them wilt for about 2 minutes. This step adds vibrant color and freshness to your soup!
6. Stir in Cheese and Seasoning:
Now, add the grated Parmesan cheese along with the dried Italian seasoning. Taste and season with salt and freshly ground black pepper as needed. Stir gently until the cheese melts and the soup becomes wonderfully creamy.
7. Let it Thicken:
Remove the pot from heat and allow the soup to sit for a few minutes. This will help it thicken slightly, making it even more satisfying.
8. Serve and Enjoy:
Serve the soup hot, garnished with fresh basil or parsley if you like. Pair it with toasted bread or garlic bread for the perfect comforting meal!

Can I Use Ground Turkey Instead of Sausage?
Absolutely! Ground turkey is a great substitute for Italian sausage if you want a lighter option. Just season it with Italian spices to mimic that classic sausage flavor!
How Should I Store Leftover Soup?
Store any leftovers in an airtight container in the fridge for up to 3 days. You can also freeze the soup in freezer-safe containers for up to 2 months. Just reheat gently on the stove or in the microwave!
Can I Make This Soup Vegetarian?
Yes, you can easily make this soup vegetarian by omitting the sausage and using vegetable broth instead of chicken broth. You can also add more vegetables like mushrooms or bell peppers for added flavor.
What’s the Best Way to Reheat the Soup?
To reheat, warm the soup gently on the stove over medium heat, stirring occasionally to ensure even heating. If it thickens too much, you can add a splash of broth or milk to achieve your desired consistency.
