Remove the casings from the sausage if purchased in links. Cook and crumble the sausage and diced onions over medium-high heat until the onions are softened and the sausage is cooked through, about 8-10 minutes. Drain grease.

Add the garlic and cook for 1 minute.

Add the flour and cook for 1-2 minutes to remove the raw flour taste.

Add basil, oregano, cayenne, hot sauce, mustard powder, pepper, and red pepper flakes. Stir to combine.

Add the chicken broth and use a silicone spatula to clean the bottom of the pot. Slowly stir in the heavy cream. Bring to a boil, then reduce to a simmer.

Add the kale and tortellini and simmer for 3-5 minutes. If your tortellini needs a longer cooking time, add the tortellini first, then the kale during the last 5 minutes.

Taste the soup and add salt if desired. Start with ¼ teaspoon and add more after that if needed.

Transfer to serving bowls and serve!
