Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Bread – Thick slices of white bread, challah, or brioche work best as they soak up the egg mixture beautifully while maintaining structure.

Deli ham – Adds savory flavor and richness. Choose thinly sliced ham for even layering throughout the casserole.

Deli turkey – Brings a lighter, meaty balance to the ham and pairs perfectly with Swiss cheese.

Swiss cheese – Classic to the Monte Cristo, it melts beautifully and gives a slightly nutty flavor. Gruyère is a fine substitute for a deeper taste.

Eggs – The base of the custard mixture that binds everything together, giving the casserole its soft, rich texture.

Milk – Whole milk or half-and-half works best for a creamy custard that’s not too heavy.

Dijon mustard – Adds a hint of tang and depth that complements the richness of the meat and cheese.

Salt and black pepper – Enhance and balance the overall flavor.

Butter – Used to grease the baking dish and add a subtle richness to the casserole.

Powdered sugar – A light dusting before serving gives it that signature Monte Cristo sweetness.

Raspberry jam or preserves – Served on the side or drizzled on top, it adds the perfect touch of fruity sweetness.

Directions

1. Prepare the baking dish: Grease a 9×13-inch casserole dish with butter and preheat your oven to 350°F (175°C).
2. Layer the ingredients: Place half of the bread slices at the bottom of the dish. Layer half the ham, half the turkey, and half the Swiss cheese over the bread. Repeat with another layer of bread, ham, turkey, and cheese.
3. Make the custard: In a large bowl, whisk together the eggs, milk, Dijon mustard, salt, and pepper until smooth.
4. Pour and soak: Gently pour the egg mixture over the assembled casserole, pressing lightly so the bread absorbs the custard. Let it sit for at least 15–20 minutes (or cover and refrigerate overnight for a make-ahead option).
5. Bake: Place the dish in the oven and bake uncovered for 40–45 minutes, or until the top is golden and the custard is set in the center.
6. Finish and serve: Allow the casserole to rest for 5–10 minutes before slicing. Dust lightly with powdered sugar and serve with raspberry jam on the side.
