Known for its smoky flavor and dense texture, kielbasa adds depth and protein without needing extra seasoning or cooking time. Learn more about its origins on Wikipedia’s kielbasa page. Pair that with sharp cheddar cheese, which melts smoothly and balances the saltiness of the sausage, and you have a casserole that hits every comforting note.
