Ingredients

  • buttered bread (2 layers)
  • 1 lb. crumbled cooked bacon
  • 8 oz. shredded Cheddar cheese
  • 15 eggs
  • 2 1/2 cups milk
  • 1 tsp. dry mustard

Instructions

  1. In a 9 x 13-inch pan, layer two slices of buttered bread.
  2. Sprinkle crumbled cooked bacon and shredded Cheddar cheese evenly over the bread.
  3. Whisk together eggs, milk, and dry mustard, then pour over the layered ingredients in the pan.
  4. Refrigerate the casserole overnight to allow flavors to meld.
  5. Bake at 300° to 325°F for 1 hour until set and golden brown.

Tips & Substitutions

For a twist, consider using ham or sausage instead of bacon, or try adding vegetables like spinach or bell peppers for extra flavor. If you want a creamier texture, substitute half of the milk with heavy cream. Be sure to use stale bread for better absorption of the egg mixture, which helps create a delightful texture reminiscent of a classic 'Killer' Casserole.

Serving Suggestions

This Holiday Brunch Casserole pairs beautifully with a fresh fruit salad or a side of roasted potatoes for a complete meal. Consider serving it alongside a light green salad or even some spiced apple cider for a festive touch. It’s perfect for breakfast or brunch gatherings and makes for an impressive centerpiece.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, preheat your oven to 350°F, cover the casserole with foil, and heat for about 20-25 minutes until warmed through. Alternatively, you can microwave individual portions for quicker reheating.
