Slow Cooker Tomato Tortellini Soup with Ground Beef

In a skillet, cook the ground beef over medium heat until browned and cooked through. Drain any excess fat and transfer the beef to the slow cooker.
Step 2: Add the Vegetables
Add the diced onion and minced garlic to the slow cooker with the beef.
Step 3: Add the Broth and Tomatoes
Pour in the beef broth and crushed tomatoes, followed by the dried basil, dried oregano, and red pepper flakes (if using).
Stir everything together and season with salt and black pepper to taste.
Step 4: Slow Cook
Cover the slow cooker and cook on low for 4-6 hours or on high for 2-3 hours. The soup is ready when the flavors have melded together.
Step 5: Add the Tortellini and Spinach
About 15 minutes before serving, add the cheese tortellini and fresh spinach to the slow cooker. Stir to combine.
Cover and let the tortellini cook until tender (about 15 minutes).
Step 6: Serve
Ladle the soup into bowls, and garnish with grated Parmesan cheese for added flavor.
