1 13x9-inch dish


  • 1 tablespoon butter, or as needed

  • 16 slices bread, or more to taste, crusts removed and discarded

  • 1 pound ham, chopped

  • ¾ pound shredded Cheddar cheese, or more to taste

  • 3 cups milk

  • 4 large eggs

  • ½ teaspoon dry mustard

  • 3 ½ cups cornflakes cereal

  • ¼ cup butter, melted


  1. Grease a 13x9-inch baking dish with 1 tablespoon butter. Cut bread slices into quarters. Arrange 1/2 of the bread evenly into the bottom and up the sides of the prepared dish to cover completely.

  2. Mix together ham and Cheddar cheese in a medium bowl; spread over bread layer in the dish and top with remaining bread.

  3. Whisk together milk, eggs, and mustard in the same bowl until smooth; pour over bread to soak completely.

  4. Put cornflakes cereal into a separate bowl; drizzle with 1/4 cup melted butter and stir to coat. Spread over the top of casserole. Cover the dish with plastic wrap and refrigerate for 8 hours to overnight.

  5. Preheat the oven to 325 degrees F (165 degrees C).

  6. Bake in the preheated oven until cornflakes are browned, about 1 hour.


You can refrigerate the unbaked casserole for a few hours (instead of 8 hours to overnight) if you're in a rush.
