Creating Italian Sausage Soup with Creamy Parmesan is a delightful process when you follow these simple steps:

1. Brown the Sausage: In a large pot or Dutch oven, cook the Italian sausage over medium heat until browned. Use a spoon to break it into smaller pieces as it cooks. Drain excess fat if needed.
2. Cook Aromatics: Add the diced onion and minced garlic to the pot. Sauté for about 2-3 minutes, or until the onion becomes translucent.
3. Add Vegetables: Add sliced carrots and celery to the pot. Cook for an additional 5 minutes, stirring occasionally.
4. Incorporate Tomatoes and Broth: Pour in the can of diced tomatoes (with juices) and the chicken broth. Stir well to combine.
5. Season to Taste: Stir in the dried Italian herbs, salt, and pepper. Bring the mixture to a boil.
6. Simmer: Reduce heat to a simmer and let it cook for 15-20 minutes, allowing the flavors to meld together.
7. Add Cream: Lower the heat and gradually stir in the heavy cream, mixing until fully incorporated.
8. Add Cheese: Sprinkle the grated parmesan cheese into the soup, stirring until it melts and creates a creamy texture.
9. Stir in Spinach: Add the fresh spinach and cook until wilted, approximately 2-3 minutes.
10. Adjust Seasoning: Taste the soup and adjust seasoning to your liking by adding more salt, pepper, or crushed red pepper flakes for spice.
