Browned Italian sausage and tender kale are simmered in a rich, ivory-colored cream broth for this low-carb version of a restaurant favorite. The dish skips the potatoes entirely, focusing on the savory fats from the sausage and the thickness of the heavy cream to create a satisfying texture. Served hot with a pinch of red pepper flakes, the soup has a bold, peppery aroma and a comforting profile that moves directly from the pot to the bowl.
