Indulge in a comforting bowl of sausage tortellini soup, where tender pasta filled with cheese pairs perfectly with savory Italian sausage and a rich tomato broth.
Cook the Sausage - In a large pot or Dutch oven, heat 1 tablespoon of olive oil over medium heat. Add the sausage, breaking it into smaller pieces. Stir until the meat is browned and fully cooked, about 5 to 7 minutes. Drain the excess grease, leaving about 1 tablespoon of drippings.
Cook the Alliums - Add the onion, saute until translucent, about 3 minutes. Add the garlic, Italian seasoning, and red pepper flakes (if using), and saute for 30 seconds.
Simmer the Soup - Stir in the tomatoes and chicken stock. Bring to a boil over medium-high heat, and then reduce to a simmer over low heat for 15 minutes.
Cook the Pasta - Increase the heat to medium-low, add the tortellini, and cook until al dente, 4 to 6 minutes.
Add the Vegetables - Add the kale and spinach, stir, and cook until the leaves are wilted, about 2 to 3 minutes.
Add the Cream - Turn off the heat and stir in the cream, salt and pepper. Taste and adjust the seasoning as needed.
To Serve - Transfer soup to serving bowls and top with basil and Parmesan cheese.
