Irish Corned Beef Bake

A cozy, cheesy layered casserole transforming leftover corned beef and cabbage into a hearty, comforting dinner.

Ingredients

  • 3 cups cooked cabbage, coarsely chopped or shredded
  • 12 oz corned beef, sliced
  • 2 cups Irish cheddar, shredded
  • 1/2 cup mustard sauce (grainy or Dijon mixed with mayo or cream)
  • 1 1/2 cups oat breadcrumbs, buttered
  • Butter for greasing the dish and dotting the crumbs

Instructions

  1. Preheat the oven to 375°F and grease a 9×9-inch baking dish with butter.
  2. Spread the cooked cabbage in an even layer across the bottom of the dish.
  3. Arrange the sliced corned beef over the cabbage in a single, slightly overlapping layer.
  4. Sprinkle the shredded Irish cheddar evenly over the meat.
  5. Spoon or spread the mustard sauce across the cheese.
  6. Scatter the buttered oat breadcrumbs over the top, pressing lightly to adhere.
  7. Bake for 30 minutes until hot, bubbly, and golden brown. Let rest for 5 minutes before slicing and serving.

Notes

For a lighter mustard sauce, substitute Greek yogurt for mayo. The dish can be assembled ahead of time and refrigerated before baking.
