Place Italian sausage in a large soup pot, break into small pieces, and cook until no pink remains. Remove sausage and set aside.
Add onion and carrots to the pot. Cook for 5-7 minutes, until onions become translucent and fragrant. Add garlic cloves, salt, thyme, and rosemary, and cook for 5 more minutes. Add flour to the pot and toss to combined. Then add broth and mix to combined. Cover and bring to a low boil.
Add tortellini, kale, and black pepper. Mix to combined then cook for 5 minutes. Once the tortellini is cooked through, add the sausage and heavy cream and cook for 2 more minutes to heat through. Taste to see if the soup needs any extra salt before serving. Now all you gotta do is eat it up!!
