What ingredients are in Hearty Lasagna Soup?
The beauty of this lasagna soup lies in its simple, accessible ingredients that come together to create something truly special. You’ll find most of these items already in your pantry or easily available at any grocery store. The combination of protein, vegetables, pasta, and cheese creates layers of flavor that mirror traditional lasagna while being infinitely easier to prepare.
Ingredients:
- 1 lb bulk Italian sausage
- 2 cups onions, chopped
- 1 cup carrot, diced
- 2 cups mushrooms, sliced
- 2 tablespoons garlic, minced
- 4 cups chicken broth
- 1 (14 1/2 ounce) can Italian-style stewed tomatoes, chopped
- 1 (10 3/4 ounce) can tomato sauce
- 1 cup mafalda pasta or campenelle pasta
- 2 cups fresh spinach, chopped
- 1 cup provolone cheese or fresh mozzarella cheese, diced
- 1/4 cup parmesan cheese, shredded (for garnish)
- 4 teaspoons thinly sliced fresh basil (for garnish)
When selecting your ingredients, opt for high-quality Italian sausage as it forms the flavor foundation of the soup. Fresh vegetables will provide the best texture and taste, though pre-sliced mushrooms can save time. The pasta shape matters—mafalda or campenelle are recommended because their ruffled edges catch the broth beautifully, but any short pasta will work in a pinch. For the cheese, using fresh mozzarella or provolone creates those signature melty pockets that make this soup reminiscent of actual lasagna. Don’t skip the fresh basil garnish; it adds a bright, aromatic finish that elevates the entire dish.
How to make this Hearty Lasagna Soup
Making this lasagna soup is wonderfully straightforward, and it all comes together in one pot, which means less cleanup for you later.
Start by browning 1 lb of bulk Italian sausage in a large saucepan over medium-high heat, breaking it up into bite-sized pieces as it cooks. Once the sausage has developed a nice brown crust, add 2 cups of chopped onions and 1 cup of diced carrots to the pan. Sauté this mixture for about 3 minutes, allowing the vegetables to soften and the onions to become translucent.
Next, stir in 2 cups of sliced mushrooms and 2 tablespoons of minced garlic, then continue cooking for another 3 minutes. You’ll notice the mushrooms releasing their moisture and the garlic becoming fragrant, which builds the aromatic foundation of your soup.
Now it’s time to add the liquids and transform this sauté into a proper soup. Pour in 4 cups of chicken broth, 1 (14 1/2 ounce) can of chopped Italian-style stewed tomatoes, and 1 (10 3/4 ounce) can of tomato sauce. Bring everything to a boil, then add 1 cup of mafalda or campenelle pasta.
Reduce the heat to maintain a gentle simmer and cook the pasta for about 10 minutes, or follow the time suggested on your pasta package. Keep an eye on it to guarantee the pasta reaches that perfect al dente texture.
Just before serving, stir in 2 cups of chopped fresh spinach and let it wilt into the soup, which only takes a minute or so.
The final step is all about creating those layers of cheesy goodness that make this soup taste like lasagna. Place 1/4 cup of diced provolone or fresh mozzarella cheese into each serving bowl, then ladle the hot soup right over the top.
The heat from the soup will melt the cheese into stretchy, delicious pockets throughout your bowl. Finish with a sprinkle of shredded Parmesan cheese and about 1 teaspoon of thinly sliced fresh basil per serving. This garnish isn’t just for looks—it adds a fresh, bright flavor that balances the richness of the cheese and sausage perfectly.

Hearty Lasagna Soup Substitutions and Variations
While this lasagna soup is absolutely delicious as written, you’ve got plenty of room to make it your own based on what you have in your kitchen or your personal preferences.
For substitution options, swap Italian sausage with ground beef, turkey, or even a plant-based crumble. If you can’t find mafalda pasta, any small pasta shape works beautifully—rotini, shells, or even broken lasagna noodles.
Don’t have provolone? Use all mozzarella or try fontina for a richer flavor.
For creative variations, add a dollop of ricotta on top instead of diced cheese, or stir in some red pepper flakes for heat. You can also bulk it up with zucchini or bell peppers.
Each tweak makes this soup uniquely yours while keeping that comforting lasagna essence intact.
What to serve with Hearty Lasagna Soup
Pairing this lasagna soup with the right sides transforms a simple bowl into a complete, satisfying meal.
I always reach for crusty bread pairings like garlic bread, sourdough, or focaccia to soak up every last drop of that flavorful broth. The crispy texture contrasts perfectly with the soup’s richness.
For side salads, I recommend keeping things light and fresh—a simple Caesar salad with romaine and parmesan works beautifully, or try an arugula salad with lemon vinaigrette to cut through the soup’s heartiness.
If you’re feeding a crowd, I’ll sometimes add roasted vegetables like zucchini or bell peppers on the side.
These accompaniments balance the meal without competing with the soup’s bold Italian flavors, making dinner feel special and well-rounded.

Final Thoughts
This lasagna soup has earned a permanent spot in my weekly dinner rotation, and I think it’ll do the same for you once you try it.
The beauty of this recipe lies in its flexibility, so don’t hesitate to make recipe adjustments based on what you have on hand. Swap the Italian sausage for ground beef, use kale instead of spinach, or add extra vegetables.
As for soup storage, it keeps beautifully in the refrigerator for up to four days. I actually prefer the leftovers because the flavors deepen overnight. Just store the soup and cheese separately to prevent the cheese from becoming stringy when reheated.
Whether you’re cooking for a crowd or meal prepping for busy weeknights, this comforting bowl delivers every single time.
Frequently Asked Questions
Can I Make This Lasagna Soup in a Slow Cooker or Instant Pot?
Yes, I can adapt this recipe for both appliances. For the slow cooker, I’ll brown the sausage first, then cook everything except pasta and spinach on low for 6-8 hours. For the Instant Pot, I’ll use sauté mode for browning, then pressure cook for 5 minutes.
How Long Does Leftover Lasagna Soup Stay Fresh in the Refrigerator?
I’ll store your leftover lasagna soup in an airtight container in the refrigerator for 3-4 days maximum. Proper leftover storage guarantees soup freshness, though the pasta may soften slightly over time.
Can I Freeze Lasagna Soup for Meal Prep Purposes?
Yes, I can freeze lasagna soup for meal prep! Here are my freezing tips: cool it completely first, store in airtight containers leaving headspace for expansion, and freeze up to three months for best quality.
What’s the Best Way to Reheat Frozen Lasagna Soup?
I’d recommend stovetop heating for the best results. Thaw your frozen lasagna soup overnight in the fridge, then reheat it gently over medium-low heat, stirring occasionally. The microwave method works too, but requires frequent stirring.
How Can I Make This Lasagna Soup Vegetarian or Vegan?
I’d swap the sausage for plant-based crumbles or extra mushrooms, use vegetable broth, and replace dairy cheese with vegan cheese alternatives. These vegetarian substitutions transform the soup while maintaining its hearty, comforting texture and flavor.
