Step-by-Step Instructions

1. Sauté the Sausage and Onion

In a large Dutch oven or soup pot, heat 1 tablespoon olive oil over medium heat. Add:

• 1 lb Italian sausage

• 1 diced yellow onion

Cook until sausage is browned and onion is soft, about 7–8 minutes. Drain excess fat if needed.

Add:

• 4 garlic cloves, minced

• 2 tablespoons tomato paste

Cook for another 1–2 minutes, stirring constantly, until fragrant and tomato paste darkens slightly.

2. Add Tomatoes and Broth

Stir in:

• 1 (28 oz) can crushed tomatoes

• 4 cups chicken or beef broth

• 1 tsp Italian seasoning

• 1 bay leaf

• Salt and black pepper to taste

• Optional: ¼ tsp crushed red pepper flakes

Bring the soup to a boil.

3. Add the Pasta

Break 8–10 lasagna noodles into rough 2-inch pieces and add to the pot. Stir well to prevent sticking.

Reduce heat and simmer 10–12 minutes, or until the noodles are tender but not mushy. Stir occasionally.

4. Cheese It Up

Once the pasta is cooked:

• Stir in ½ cup shredded mozzarella, if you want melty cheese throughout.

• Remove the bay leaf.

Taste and adjust seasoning.

5. Serve with Toppings

Ladle soup into bowls and top each serving with:

• A generous spoonful of ricotta cheese

• A sprinkle of shredded mozzarella

• A dusting of Parmesan cheese

Let the cheese melt slightly before diving in.

Tips, Variations & Substitutions

Tips for Perfect Lasagna Soup:

• Stir the pasta often to prevent clumping.

• If the soup thickens too much as it sits, add a splash of broth when reheating.

• Don’t overcook the pasta — it will continue to soften in the hot broth.

Flavor Variations:

• Creamy Version: Stir in ½ cup of heavy cream or mascarpone for a rich, velvety broth.

• Spicy Version: Use hot Italian sausage and extra chili flakes.

• Loaded Veggie Version: Add chopped spinach, mushrooms, or zucchini in the last 5 minutes of cooking.

Substitutions:

• Turkey or Chicken Sausage: For a leaner option.

• No Ricotta? Use cottage cheese or a spoonful of cream cheese.

• Gluten-Free: Use gluten-free lasagna noodles or short pasta.

• Dairy-Free: Use dairy-free ricotta and mozzarella alternatives.

FAQs

Q1: Can I make this ahead of time?

A1: Yes! For best results, cook the soup without pasta and refrigerate. Add pasta while reheating to prevent it from getting mushy.

Q2: Can I freeze lasagna soup?

A2: You can freeze it, but for best texture, freeze it before adding pasta. Add fresh-cooked pasta when you reheat.

Q3: How do I store leftovers?

A3: Store in an airtight container in the fridge for up to 4 days. Add a splash of broth when reheating, as pasta will absorb liquid.

Q4: Can I make it in the slow cooker?

A4: Yes — brown sausage and aromatics first, then add to slow cooker with tomatoes and broth. Cook on LOW 6–7 hours. Add pasta in the last 30 minutes.

Q5: What pasta works best?

A5: Broken lasagna noodles are classic, but mafalda, rotini, penne, or bowtie pasta all work well.

Q6: Can I add vegetables?

A6: Definitely. Stir in spinach, zucchini, or mushrooms during the last 5–10 minutes of simmering.

Q7: Is this recipe kid-friendly?

A7: Very! You can skip the red pepper flakes for a milder version kids will love. Serve with cheesy bread for extra smiles.
