Make this rich and velvety creamy sausage tortellini soup on the stovetop in just 30 minutes. It is a hearty, one-pot comfort food perfect for a busy weeknight dinner.
Heat the olive oil in a large pot or Dutch oven over medium heat. Add the Italian sausage and cook, breaking it up with a spoon, until browned. Drain off excess grease.
Add the chopped onion to the pot and cook until softened, about 5 minutes. Add the minced garlic and cook for 1 minute more until fragrant.
Pour in the chicken broth and add the diced tomatoes (with their juice), Italian seasoning, salt, and pepper. Bring the mixture to a simmer.
Add the cheese tortellini to the simmering broth. Cook according to package directions, usually about 5 to 7 minutes, until the tortellini float and are tender.
Stir in the fresh spinach until it wilts into the soup, which takes about 1 minute.
Reduce the heat to low. Stir in the heavy cream and grated Parmesan cheese until the soup is heated through and creamy. Do not let the soup boil after adding the cream.
Serve this hearty sausage soup immediately.
Notes
You can substitute mild Italian sausage for spicy if you prefer less heat.
For a thicker soup, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water before stirring it into the simmering broth in Step 4.
