Make this hearty, velvety sausage tortellini soup in just 30 minutes using only one pot. It is a satisfying comfort food dinner perfect for busy weeknights.
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 refrigerated tortellini to the simmering broth. Cook according to package directions, usually about 5 to 7 minutes, until the tortellini are tender.
Stir in the fresh spinach until it wilts into the soup, which takes about 2 minutes.
Reduce the heat to low. Stir in the heavy cream until the broth is fully incorporated and creamy. Do not let the soup boil after adding the cream.
Remove the pot from the heat. Stir in the grated Parmesan cheese until melted and smooth. Serve this cozy winter soup immediately.
Notes
For a richer flavor, use sweet Italian sausage instead of mild.
You can substitute kale for spinach if you prefer a heartier green in your soup with kale and sausage.
