Prepare this sweet and savory Monte Cristo Breakfast Casserole the night before for an easy, crowd-pleasing brunch dish featuring ham, turkey, and Swiss cheese baked in a French toast custard.

Ingredients

Scale
  • 1 loaf (16 ounces) Challah or thick-cut white bread, cut into 1-inch cubes
  • 1 pound thinly sliced deli ham, cut into pieces
  • 1 pound thinly sliced deli turkey, cut into pieces
  • 12 ounces Swiss cheese, shredded
  • 6 large eggs
  • 2 cups whole milk
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1 tablespoon granulated sugar
  • Powdered sugar, for dusting
  • Maple syrup, for serving

Instructions

  1. Lightly grease a 9×13 inch baking dish. Arrange half of the bread cubes in the bottom of the dish.
  2. Layer half of the ham, half of the turkey, and half of the Swiss cheese over the bread layer. Repeat with the remaining bread, meat, and cheese.
  3. In a large bowl, whisk together the eggs, milk, vanilla extract, cinnamon, nutmeg, and 1 tablespoon of sugar until well combined.
  4. Slowly pour the egg mixture evenly over the bread and meat layers in the baking dish, pressing down gently to help the bread absorb the liquid.
  5. Cover the dish tightly with plastic wrap. Refrigerate for at least 4 hours, or preferably overnight.
  6. When ready to bake, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Remove the plastic wrap.
  7. Bake uncovered for 45 to 55 minutes, or until the casserole is puffed, set in the center, and golden brown on top. If the top browns too quickly, loosely cover it with foil.
  8. Let the casserole rest for 10 minutes before slicing and serving. Dust generously with powdered sugar and serve with warm maple syrup on the side.

Notes

  • Using Challah bread provides the best texture, but Texas toast or brioche also work well.
  • For a richer flavor, you can substitute half-and-half for some of the milk.
  • If you need to bake this immediately, let the assembled casserole sit at room temperature for 30 minutes before baking to allow for better liquid absorption.
