Creating Alfredo Lasagna Soup is straightforward when you follow these simple steps:

1. Brown the Meat: In a large pot or Dutch oven, cook the Italian sausage over medium heat until browned. Drain any excess fat.
2. Sauté the Onion and Garlic: Add the diced onion to the pot and sauté until it becomes translucent. Stir in the minced garlic and cook for an additional minute until fragrant.
3. Add Broth and Tomatoes: Pour in the chicken or vegetable broth and add the canned diced tomatoes, bringing the mixture to a boil.
4. Incorporate Noodles: Add the broken lasagna noodles to the boiling broth. Reduce the heat and let it simmer for about 10-12 minutes until the noodles are tender.
5. Stir in Cream and Cheeses: Once the noodles are cooked, stir in the heavy cream, mozzarella cheese, and grated Parmesan cheese. Allow it to simmer for another 2-3 minutes until the cheeses are melted and the soup is creamy.
6. Season to Taste: Add the dried basil, oregano, salt, and pepper, adjusting to your liking.
7. Garnish: Ladle the soup into bowls and garnish with fresh parsley if desired.

These simple steps will guide you in effortlessly creating this incredible soup that captures the essence of traditional lasagna.
