Step 1: Prepare the Soup Base
In a slow cooker, combine the browned Italian sausage, sliced onion, minced garlic, and diced tomatoes.
Pour in the vegetable broth and season with dried basil, oregano, salt, and pepper. Stir to combine.
Cover and cook on low heat for 6-7 hours or on high heat for 3-4 hours.
Step 2: Add Tortellini and Spinach
About 30 minutes before serving, add the cheese tortellini and chopped spinach to the slow cooker.
Stir in the heavy cream until fully incorporated.
Cover and continue cooking on high heat for an additional 25-30 minutes, or until the tortellini is tender.
Step 3: Serve and Garnish
Ladle the soup into bowls and garnish with grated Parmesan cheese.
Serve hot and enjoy the rich, savory flavors of this creamy tortellini soup.
