Irish Cottage Pie is a comforting baked dish consisting of a hearty beef filling topped with creamy mashed potatoes. The beef is simmered with vegetables and spices until rich and flavorful, then layered with a fluffy potato mash that turns golden and crispy on top after baking, resulting in a textured, savory casserole.
For extra flavor, add chopped fresh parsley or a dash of Guinness stout to the beef filling. Adjust seasoning to your taste, and feel free to experiment with cheese on top for a richer finish.
