Alfredo Lasagna Soup (Print version)

Creamy Alfredo Lasagna Soup with Italian sausage, tender noodles, spinach, mushrooms, and a rich Parmesan broth.

# Ingredients:

For the soup base

01 - 1 tablespoon olive oil
02 - 1 lb (450 g) mild Italian sausage, casings removed if needed
03 - 1 medium yellow onion, diced
04 - 8 oz (225 g) cremini mushrooms, sliced
05 - 4 cloves garlic, minced
06 - 1 teaspoon Italian seasoning
07 - 1/4 teaspoon crushed red pepper flakes, optional
08 - 1/2 teaspoon black pepper
09 - 5 cups (1.2 L) low-sodium chicken broth
10 - 8 oz (225 g) dry lasagna noodles, broken into bite-size pieces

For the Alfredo finish

11 - 3 tablespoons unsalted butter
12 - 3 tablespoons all-purpose flour
13 - 1 cup (240 ml) whole milk
14 - 1 cup (240 ml) heavy cream
15 - 1 cup (90 g) freshly grated Parmesan cheese
16 - 3 cups (85 g) baby spinach
17 - Salt, to taste

For serving

18 - 3/4 cup (185 g) ricotta cheese
19 - 1 cup (115 g) shredded mozzarella cheese
20 - 2 tablespoons chopped fresh parsley
21 - Extra Parmesan, for serving

# Instructions:

01 - Heat olive oil in a large Dutch oven over medium-high heat. Add the sausage and cook for 6-8 minutes, breaking it up, until browned and cooked through.
02 - Add onion and mushrooms to the pot. Cook for 5-6 minutes, stirring often, until the onion softens and the mushrooms release their moisture.
03 - Stir in garlic, Italian seasoning, red pepper flakes, and black pepper. Cook for 30 seconds, just until fragrant.
04 - Pour in the chicken broth and bring to a simmer. Add the broken lasagna noodles and cook for 9-11 minutes, stirring often, until just tender.
05 - Lower the heat to medium-low. Add butter and stir until melted, then sprinkle in flour and stir for 1 minute. Slowly stir in milk and cream until the broth looks smooth.
06 - Stir in Parmesan a handful at a time until melted. Add spinach and cook for 1-2 minutes until wilted. Taste and add salt only if needed.
07 - Ladle the soup into bowls. Top each serving with ricotta, mozzarella, parsley, and extra Parmesan. Serve hot.

# Good to know:

01 - Best served right after cooking while the noodles are tender and the broth is creamy.
02 - For make-ahead soup, cook the noodles separately and add them to each bowl.
03 - Leftovers keep refrigerated for up to 3 days.
