Ingredients for Monte Cristo French Toast Casserole

1 loaf (14-16 oz) French bread or brioche, cut into 1-inch cubes
12 oz sliced deli ham
8 oz sliced turkey breast
8 oz Swiss cheese, sliced or shredded
6 large eggs
2 cups whole milk
1/2 cup heavy cream
1/4 cup maple syrup, plus extra for serving
2 tbsp Dijon mustard
1/2 tsp ground black pepper
1/4 tsp salt
2 tbsp powdered sugar, for dusting

How to Make Monte Cristo French Toast Casserole

Step 1: Prep the Bread and Layers

Grease a 9×13-inch baking dish with butter or cooking spray. Spread half of the bread cubes evenly in the bottom. Layer with half the ham, turkey, and Swiss cheese. Repeat with remaining bread, ham, turkey, and cheese, pressing down lightly.

Step 2: Whisk the Custard

In a large bowl, whisk together eggs, milk, heavy cream, maple syrup, Dijon mustard, salt, and black pepper until well combined.

Step 3: Assemble and Chill

Slowly pour the egg mixture evenly over the casserole, making sure every piece is soaked. Cover tightly with plastic wrap and refrigerate for at least 2 hours, or overnight for best results.

Step 4: Bake the Casserole

Preheat your oven to 350°F (175°C). Remove plastic wrap and let casserole sit at room temperature for 20 minutes. Bake uncovered for 40-45 minutes, or until the top is golden and the center is set. If it browns too quickly, tent with foil for the last 10 minutes.

Step 5: Finish and Serve

Allow casserole to cool for 10 minutes before dusting with powdered sugar. Slice and serve warm with a drizzle of maple syrup on top.

Notes for the Perfect Monte Cristo French Toast Casserole

Use stale or day-old bread to help soak up the custard without getting soggy.
Want it cheesier? Sprinkle extra Swiss cheese on top for the final 10 minutes of baking.
