In a soup pot or dutch oven, brown and crumble the sausages until cook through over medium heat.
Leaving behind about 1 tablespoon of the rendered fat, remove the sausage from the pan and transfer on to paper towels to drain.
Add onion and garlic to the fat in the pot and cook until soft and fragrant, about 3-4 minutes.
Stir chicken broth into the onions and garlic and stir in the potatoes and salt. Bring pot to a simmer and let cook until the potatoes are tender, about 12-15 minutes.
Stir the kale into the soup followed by the cream. Serve with crusty bread and Parmesan cheese.
