Tips & Variations
- Use whole wheat or brioche bread for a different texture and richer flavor.
- Swap Swiss cheese for Gruyère or cheddar to change the cheese profile.
- For a spicier kick, add a pinch more cayenne or some finely chopped jalapeños.
- To make it vegetarian, replace the ham and turkey with sautéed mushrooms or roasted vegetables.
- Letting the casserole soak overnight helps the bread absorb more custard for a tender, sliceable dish.

Ingredients
Bread and Meats
- 12 slices of white bread, crusts removed
- 8 ounces of deli ham, thinly sliced
- 8 ounces of deli turkey, thinly sliced
Cheese
- 8 ounces of Swiss cheese, sliced
Egg Mixture
- 6 large eggs
- 2 cups of milk

- 1 teaspoon of salt
- 1/2 teaspoon of black pepper
- 1/4 teaspoon of cayenne pepper
Additional Ingredients
- 2 tablespoons of butter, melted
- Powdered sugar for dusting
- Raspberry jam for serving (optional)
Instructions
- Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with a bit of the melted butter to prevent sticking and help with browning.
- First Bread Layer: Lay out 6 slices of white bread evenly on the bottom of the greased baking dish forming a single layer to create the base of the casserole.
- Add Meat and Cheese Layer: Evenly distribute half of the sliced ham, turkey, and Swiss cheese over the bread layer to layer flavors and richness.
- Second Bread Layer: Place the remaining 6 slices of bread on top of the meat and cheese layer, followed by the remaining ham, turkey, and Swiss cheese to build the casserole’s layers.
- Prepare Egg Mixture: In a large bowl, whisk together the eggs, milk, Dijon mustard, salt, black pepper, and cayenne pepper until the mixture is smooth and well combined, ensuring an evenly flavored custard.
- Pour Egg Mixture: Slowly pour the egg mixture evenly over the layers in the baking dish, gently pressing down to help the bread absorb the liquid for a moist and cohesive casserole.
- Add Butter: Drizzle the remaining melted butter over the top of the casserole to enhance flavor and help the top turn a rich golden brown during baking.
- Rest the Casserole: Cover the dish with foil and let it sit for at least 30 minutes or refrigerate overnight to fully soak the bread and meld flavors.
- First Bake: Bake the casserole, covered with foil, in the preheated oven for 30 minutes to set the egg and start cooking the casserole through.
- Finish Baking: Remove the foil and continue baking for an additional 15-20 minutes or until the top is golden brown and the egg mixture is completely set for a perfect texture.
- Cool and Garnish: Allow the casserole to cool slightly before dusting the top with powdered sugar for a signature Monte Cristo taste contrast.
- Serve: Serve warm with a side of raspberry jam for optional sweetness that complements the savory layers beautifully.
Notes
- For best flavor, allow the casserole to rest covered overnight so the bread soaks up the egg mixture thoroughly.
- Using crust-less white bread prevents a tougher texture and helps the casserole absorb the liquid evenly.
- Feel free to substitute Swiss cheese with Gruyere or another melty cheese of your choice.
- To make individual servings, consider baking the casserole in muffin tins instead of one dish.
- Store leftovers covered in the refrigerator for up to 3 days and reheat gently in the oven.
