1 pound sausage (Italian or your preferred variety)
1 medium onion, diced
1 box (4 cups) chicken broth
1 small can (6 oz) tomato paste
1 can (14.5 oz) diced tomatoes (Rotel with green chiles recommended for extra flavor)
1 tsp thyme
Salt and pepper to taste
1 bag (9 oz) cheese tortellini (fresh or frozen)
1 bag (5 oz) fresh kale
1 cup heavy whipping cream
Parmesan cheese for serving
In a skillet over medium heat, brown the sausage until fully cooked. Add the diced onion and sauté until softened. Drain any excess fat.
Transfer the browned sausage and onions to your crockpot. Add the chicken broth, tomato paste, diced tomatoes, thyme, salt, and pepper. Stir to combine.
Cover and cook on low for 8 hours or on high for 4 hours. About an hour before serving, add the tortellini, kale, and heavy whipping cream to the crockpot. Stir well, cover, and let it cook down for the remaining hour. Ladle the soup into bowls and sprinkle with Parmesan cheese. Enjoy your hearty, flavorful tortellini soup!
