This hearty casserole pairs wonderfully with a variety of side dishes that complement its rich flavors. Mashed potatoes, with their creamy texture and buttery taste, make an excellent base for the casserole's savory sauce. Steamed green beans add a fresh, crisp contrast to the dish, while crusty bread is perfect for soaking up any remaining sauce on your plate. These sides not only balance the meal but also enhance the dining experience, allowing the flavors of the casserole to shine.
