How to Make Monte Cristo Breakfast Casserole – Sweet, Savory & Melt-In-Your-Mouth Delicious!

1. Preheat your oven to 350°F and grease a 9×13-inch baking dish with butter or nonstick spray.
2. In a large bowl, whisk together eggs, whole milk, heavy cream, granulated sugar, Dijon mustard, vanilla extract, salt, and black pepper until fully combined and smooth.
3. Layer half of the bread cubes evenly in the prepared baking dish. Evenly distribute half of the chopped ham and turkey over the bread, then sprinkle with half of the shredded Swiss cheese. Repeat with the remaining bread, meats, and cheese.
4. Pour the egg mixture evenly over the casserole, pressing down gently with a spatula to help soak the bread. Drizzle melted butter over the top to enhance crispiness.
5. Cover the dish tightly with aluminum foil and refrigerate for at least 1 hour or overnight to allow the bread to soak up the custard fully.
6. Remove the foil and bake the casserole at 350°F for 45-50 minutes, or until the top is golden brown and a knife inserted in the center comes out clean.
7. Let the casserole rest for 10 minutes before dusting generously with powdered sugar and serving. The sweet dusting balances the savory flavors beautifully.

Tips for the Best Results

• Use day-old brioche or challah bread for the best texture; fresh bread can become too soggy.
• Refrigerate the casserole overnight to deepen flavors and ensure the custard soaks thoroughly.
• Feel free to swap turkey or ham for your favorite breakfast meats like Canadian bacon or smoked chicken.
• Don’t skip the powdered sugar garnish—it adds a signature sweet contrast to the savory layers.
• Serve with a side of maple syrup or Dijon mustard for dipping to add extra flavor layers.

Storage and Reheating

Store leftover monte cristo casserole in an airtight container in the refrigerator for up to 3 days. For longer storage, you can freeze individual portions wrapped tightly in plastic wrap and aluminum foil for up to 2 months.

To reheat, warm in a 350°F oven for 15-20 minutes or until heated through. You can also microwave individual servings for 1-2 minutes, but reheating in the oven helps keep the casserole’s crispy top texture.

Frequently Asked Questions

Can I make this casserole dairy-free?

Yes, you can substitute the milk and cream with dairy-free alternatives like almond or oat milk and use a dairy-free cheese alternative. Keep in mind this will change the flavor slightly.

Can I prepare this casserole without overnight soaking?

While you can bake it immediately after assembling, letting it soak overnight enhances the custard absorption and flavor, resulting in a more tender and flavorful casserole.

What bread works best for monte cristo casserole?

Brioche or challah are ideal because of their slightly sweet, rich texture, but you can also use French bread or Texas toast if needed.

Is this casserole suitable for meal prep or feeding a crowd?

Absolutely! This monte cristo casserole is perfect for meal prep and feeding guests, as it can be made ahead, baked fresh, and easily scaled up to serve more people.
