Ingredients Overview
Soft sandwich bread forms the base of Easy Monte Cristo Breakfast Casserole (Sweet & Savory Recipe). Brioche or challah adds subtle sweetness and richness, while standard white sandwich bread works well for a lighter option. Slightly stale bread absorbs the custard more effectively.
Deli ham and turkey create the signature savory layer. Choose thinly sliced, high-quality meats for the best texture and flavor.
Swiss cheese provides a mild, slightly nutty melt that pairs beautifully with the meats. Gruyère can be substituted for deeper flavor.
Eggs and milk form the custard that binds the casserole together. Whole milk creates richness, while half-and-half makes it even creamier.
A small amount of Dijon mustard enhances the savory profile without overpowering the sweetness. Maple syrup or a light sprinkle of sugar in the custard adds the classic sweet element associated with a Monte Cristo.
Salt and freshly ground black pepper balance the flavors. A light dusting of powdered sugar after baking gives the casserole its signature finish.
Optional raspberry preserves can be served on the side for those who enjoy the traditional sweet contrast.

Step-by-Step Instructions
Preheat the oven to 350°F. Lightly grease a 9×13-inch baking dish.
Cut the bread into cubes, roughly 1-inch in size. Spread half of the bread evenly across the bottom of the prepared dish.
Layer half of the ham and turkey over the bread, followed by half of the shredded Swiss cheese.
Repeat with the remaining bread, meats, and cheese to create even layers.
In a large bowl, whisk together eggs, milk, Dijon mustard, maple syrup or sugar, salt, and black pepper until fully combined.
Pour the egg mixture evenly over the layered casserole, pressing gently on the bread to help it absorb the custard.
Cover with foil and refrigerate for at least 30 minutes, or up to overnight for a make-ahead option.
Bake covered for 30 minutes. Remove the foil and bake an additional 15 to 20 minutes, until the top is golden and the center is set.
Allow the casserole to rest for 10 minutes before slicing. Lightly dust with powdered sugar just before serving.
Tips, Variations & Substitutions
For extra richness, substitute half of the milk with half-and-half.
If you prefer a more pronounced sweet note, drizzle a small amount of maple syrup over the top before baking uncovered.
Croissants can replace sandwich bread for a softer, more buttery texture.
Add a thin layer of cream cheese between the bread layers for added creaminess.
For a slightly crisp top, broil for 1 to 2 minutes at the end of baking, watching carefully.
Serving Ideas & Occasions
Easy Monte Cristo Breakfast Casserole (Sweet & Savory Recipe) is perfect for holiday mornings, brunch gatherings, or special weekend breakfasts.
