This recipe creates a hearty soup by combining thinly sliced potatoes with browned Italian sausage and onions in a flavorful broth enriched with milk, half-and-half, and seasonings. The soup is finished by simmering with kale and a touch of heavy cream until tender.
Ensure potatoes are only slightly softened before adding to the main pot; they will finish cooking in the soup. Draining excess fat from the sausage is key for a balanced soup base. Taste and adjust seasoning liberally before adding potatoes and kale. For a richer texture, you can blend a small portion of the soup after the potatoes soften, then return it to the pot before adding kale. Garnish with fresh herbs or grated Parmesan cheese for added depth.
