I can hardly contain my excitement when I think about this Monte Cristo Breakfast Casserole! The combination of sweet and savory flavors, the comforting aroma that fills my kitchen as it bakes – it’s pure magic. I first made a dish similar to this year ago, inspired by my love of Monte Cristo sandwiches, but like my Blueberry French Toast Casserole, this has become a weekend tradition in our household.

What Makes This Monte Cristo Breakfast Casserole So Special?

What I adore most about this Monte Cristo Breakfast Casserole is how simple yet satisfying it is. With just 20 minutes of prep time and 40 minutes in the oven, you can have a show-stopping breakfast or brunch ready to delight everyone. The combination of challah bread, savory cooked ham and turkey, and melted Swiss cheese, all bathed in a luscious custard made with large eggs, whole milk, heavy cream, maple syrup, and a hint of cinnamon and nutmeg, creates a symphony of flavors that’s simply irresistible.

The Key Ingredients You’ll Need

Let’s talk about what makes this casserole truly shine. First, the challah bread. I find that its slightly sweet and eggy flavor enhances the overall experience beautifully. If you can’t find challah, brioche works wonderfully too. Second, the Swiss cheese – its nutty and slightly tangy flavor complements the ham and turkey perfectly, creating a harmonious blend of flavors. Finally, don’t skimp on the maple syrup! A good quality maple syrup adds a touch of sweetness and depth that ties everything together.

Ingredients
  

For the Casserole:
  • 1 loaf Challah Bread cut into 1-inch cubes
  • 1 lb Cooked Ham sliced
  • 1 lb Cooked Turkey sliced
  • 8 oz Swiss Cheese shredded
For the Custard:
  • 8 Large Eggs
  • 2 cups Whole Milk
  • 1/2 cup Heavy Cream
  • 1/4 cup Maple Syrup
  • 2 tsp Vanilla Extract
  • 1/2 tsp Ground Cinnamon
  • 1/4 tsp Ground Nutmeg
  • 1/4 tsp Salt
For Serving:
  • Powdered Sugar for dusting
  • Maple Syrup for drizzling
  • Strawberry Jam for serving

Equipment

  • 9x13 inch baking dish
  • Mixing Bowl
  • Whisk

Method
 

Prepare the Casserole:
  • Grease a 9x13 inch baking dish.
  • Arrange half of the cubed challah bread evenly in the prepared baking dish. Top with half of the ham, turkey, and Swiss cheese.
  • Repeat the layers with the remaining challah bread, ham, turkey, and Swiss cheese.
Make the Custard:
  • In a large mixing bowl, whisk together the eggs, milk, heavy cream, maple syrup, vanilla extract, cinnamon, nutmeg, and salt until well combined.
Assemble and Bake:
  • Pour the custard mixture evenly over the layered bread, ham, turkey, and cheese in the baking dish. Gently press down on the bread to ensure it is soaked in the custard.
  • Cover the baking dish with plastic wrap and refrigerate for at least 2 hours, or preferably overnight, to allow the bread to absorb the custard.
  • Preheat your oven to 350°F (175°C).
  • Remove the plastic wrap and bake the casserole in the preheated oven for 40-45 minutes, or until the top is golden brown and the custard is set. A knife inserted into the center should come out clean.
Serve:
  • Let the casserole cool slightly before cutting into squares.
  • Dust with powdered sugar and drizzle with maple syrup. Serve warm with a side of strawberry jam.

Notes

For a richer flavor, use brioche bread instead of challah. Feel free to adjust the amount of maple syrup to your preference. Leftovers can be stored in the refrigerator for up to 3 days.

How I Make Monte Cristo Breakfast Casserole

Alright, let’s dive into how I bring this Monte Cristo Breakfast Casserole to life! First, I prepare the casserole by cubing the challah bread and layering it with cooked ham, cooked turkey, and Swiss cheese in a baking dish. Then, I make the custard by whisking together large eggs, whole milk, heavy cream, maple syrup, vanilla extract, ground cinnamon, ground nutmeg, and salt. Once the custard is ready, I pour it evenly over the bread and meat mixture. Finally, I assemble and bake the casserole until it’s golden brown and bubbly. It’s really that simple!

My Tips for the Perfect Outcome

Here are a few tips I’ve learned over time to ensure your Monte Cristo Breakfast Casserole turns out perfectly every single time:

  • Don’t overbake: Keep a close eye on the casserole while it’s in the oven. You want it to be golden brown and set, but still slightly soft in the center.
  • Use good quality ingredients: The better the ingredients, the better the flavor of the casserole.
  • Let it rest: After baking, let the casserole rest for at least 10 minutes before serving. This allows the custard to set up completely.

Serving Suggestions and Storage Tips

I love serving this Monte Cristo Breakfast Casserole warm, dusted with powdered sugar and drizzled with maple syrup. A side of fresh fruit and a dollop of strawberry jam completes the experience perfectly. For leftovers, I store them in an airtight container in the refrigerator for up to 3 days. You can reheat individual portions in the microwave or oven. Also, if you’re looking for a different twist on casseroles, you might enjoy my Ground Turkey Zucchini Casserole.
