INGREDIENTS
- ½ lb ground sausage
- 1 small onion, chopped
- 8 ounces mushrooms, sliced
- 2 cloves garlic, minced
- 4 cups baby spinach
- 5 cups low-sodium chicken broth
- 5 lasagna noodles, broken into pieces
- 1 teaspoon dried oregano
- ½ teaspoon dried basil
- 3 tablespoons butter
- 3 tablespoons flour
- 1 cup milk
- 1 cup Parmesan cheese, grated
INSTRUCTIONS
Step 1: Cook the Sausage and Vegetables
Brown the ground sausage in a large saucepan over medium heat. Add the onion and mushrooms and cook for 5-6 minutes over medium-low heat.
Step 2: Add Garlic and Spinach
Add the garlic and spinach and cook for 1 minute, stirring.
Step 3: Add Broth and Simmer
Add the chicken broth and simmer for 5 minutes. Add the broken lasagna noodles, oregano, and basil, and bring to a low boil. Cook for 10-12 minutes, or until the noodles are tender.
Step 4: Make the Creamy Alfredo Base
Meanwhile, in a skillet over medium-low heat, melt the butter. Whisk in the flour and continue cooking for 1 minute, whisking constantly. The butter/flour mixture should be bubbling. Slowly whisk in the milk until the mixture is smooth and thickened, about 3-5 minutes.
Step 5: Add the Parmesan
Turn off the heat and slowly whisk in the Parmesan cheese. If the cheese is not melting, place it over very low heat and whisk constantly. When the Parmesan is fully melted and the mixture is creamy, slowly add it to the soup mixture, whisking it in.
TIPS
- Break the noodles into bite-sized pieces — they cook more evenly and are easier to eat.
- Use freshly grated Parmesan — it melts more smoothly and has better flavor than pre-shredded.
- Whisk constantly when making the Alfredo base — this prevents lumps and ensures a smooth, creamy sauce.
- Add the Alfredo base at the end — this keeps the soup creamy and prevents the dairy from curdling.
- Customize your protein — use ground beef, chicken, or Italian sausage for a different twist.
