A quick and comforting breakfast casserole featuring cubed stale bread soaked in a seasoned egg custard with ham and a blend of cheddar and mozzarella cheeses. Perfect for busy mornings, brunch, or dinner.

Ingredients

Scale
  • 6 cups cubed stale bread (white, sourdough, or whole wheat)
  • 2 cups diced cooked ham
  • 1 cup shredded sharp cheddar cheese
  • 1 cup shredded mozzarella cheese
  • 8 large eggs (room temperature)
  • 2 cups whole milk or half-and-half
  • 1 teaspoon Dijon mustard
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon garlic powder
  • ½ teaspoon dried thyme or Italian seasoning
  • 2 tablespoons unsalted butter, melted (for greasing the casserole dish)

Instructions

  1. Preheat the oven to 350°F (175°C). Butter your casserole dish thoroughly.
  2. Cube about 6 cups of stale bread into roughly 1-inch cubes. If bread is fresh, toast lightly to dry it out.
  3. Dice 2 cups of cooked ham into bite-sized pieces.
  4. In a large bowl, whisk together 8 large eggs, 2 cups whole milk or half-and-half, 1 teaspoon Dijon mustard, 1 teaspoon salt, ½ teaspoon black pepper, ½ teaspoon garlic powder, and ½ teaspoon dried thyme until combined and slightly frothy.
  5. Add the cubed bread, diced ham, and shredded cheeses (1 cup cheddar and 1 cup mozzarella) to the custard mixture. Stir gently to coat evenly.
  6. Pour the mixture into the prepared casserole dish and spread evenly. Let sit for 5 minutes to soak.
  7. Bake for 40-45 minutes or until the top is golden brown and a knife inserted in the center comes out clean.
  8. Let the casserole cool for about 10 minutes before slicing and serving.

Notes

Use stale or day-old bread to prevent sogginess. Toast fresh bread if needed. Let the casserole rest after baking for cleaner slices. Mustard in the egg mixture brightens flavor. Can be assembled the night before and refrigerated; add 10 minutes to baking time if doing so. Tent with foil if browning too fast.
