Ingredients You’ll Need

This recipe uses simple ingredients that come together to create a rich and balanced dish.

8 slices bread (brioche or white), cut into cubes
8 oz deli ham, sliced
8 oz deli turkey or chicken, sliced
8 oz Swiss cheese, shredded
6 large eggs
2 cups milk
1 teaspoon Dijon mustard
1 teaspoon vanilla extract
1/2 teaspoon salt
1/4 teaspoon black pepper
1/4 teaspoon nutmeg
Powdered sugar (for topping)
Maple syrup (for serving)

How to Make Monte Cristo Breakfast Casserole

Start by preheating your oven to 350°F (175°C) and greasing a baking dish.

Spread half of the bread cubes evenly in the dish. Layer ham, turkey, and half of the cheese over the bread. Add the remaining bread cubes on top to form a second layer.

In a large bowl, whisk together eggs, milk, Dijon mustard, vanilla extract, salt, pepper, and nutmeg until smooth. Pour this mixture evenly over the layered bread and meats, making sure everything is well soaked.

Gently press down so the bread absorbs the custard. Cover the dish and refrigerate for at least 1 hour, or overnight for best results.

Before baking, let the dish sit at room temperature for about 15 minutes. Bake covered for 30 minutes, then uncover and bake for another 15–20 minutes until the top is golden and the center is fully set.

Let it cool slightly before slicing. Serve warm with a dusting of powdered sugar and a drizzle of maple syrup.

Serving Ideas

This casserole pairs beautifully with fresh fruits like berries for a refreshing contrast. You can also serve it with a light salad or simple toast to create a complete meal. For extra flavor, offer additional maple syrup or a touch of honey on the side.

Helpful Tips

For extra flavor, you can add sautéed vegetables like onions, spinach, or bell peppers. Make sure they are well drained before adding them to avoid excess moisture.

You can switch the bread type depending on your preference—brioche gives a richer texture, while sourdough adds a slight tang.

Preparing the casserole the night before makes mornings easier and allows the flavors to blend perfectly.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave for a quick option or in the oven at 350°F for a crispier texture.

You can also freeze individual portions for up to 2 months. Thaw overnight in the fridge before reheating.
