Step‑by‑Step Instructions for Monte Cristo Breakfast Casserole

Step 1: Preheat and Prep the Dish
Start by preheating your oven to 350°F (175°C). While the oven heats, grease a 9×13-inch baking dish with butter or non-stick spray to ensure your Monte Cristo Breakfast Casserole comes out easily and has a beautiful golden crust. This step sets the stage for a delightful brunch experience.

Step 2: Cube the Bread
Take four slices of day-old white bread and cut them into cubes, about one-inch in size. Evenly distribute the bread cubes across the bottom of your greased baking dish, ensuring they cover the base completely. This layer acts as the foundation, soaking up the delicious egg mixture once we assemble the casserole.

Step 3: Layer the Meats and Cheese
Next, add a generous layer of savory, sliced ham on top of the bread cubes. Follow this with a layer of turkey slices, evenly distributing them to cover the ham. Finally, place the Swiss cheese slices over the meat layers, allowing the cheese to melt beautifully during baking, which adds richness to the Monte Cristo Breakfast Casserole.

Step 4: Add More Bread
Now, cube the remaining four slices of bread and sprinkle these over the cheese layer. This second layer will absorb the egg mixture beautifully, creating a delightful texture in your casserole. Remember, the more day-old bread you use, the fluffier the final dish will be, making it a family favorite.

Step 5: Whisk the Egg Mixture
In a medium bowl, whisk together six large eggs, 1.5 cups of milk, 0.25 cups of maple syrup, 0.5 teaspoon of salt, and 0.25 teaspoon of pepper until the mixture is smooth and combined. This egg mixture is crucial as it binds all the ingredients together, ensuring every bite of the Monte Cristo Breakfast Casserole is flavorful and satisfying.

Step 6: Combine and Soak
Pour the egg mixture evenly over the bread, meat, and cheese layers in the baking dish. Use a spatula to gently press down the layers, ensuring the bread absorbs the egg mixture thoroughly. If you have extra time, letting the casserole rest for 10-15 minutes before baking enhances the overall texture, allowing for maximum flavor.

Step 7: Finish with Butter
Drizzle 0.25 cups of melted butter over the top of the casserole, which will create a beautiful golden crust during baking. This addition enriches the dish and enhances the delightful flavors of the Monte Cristo Breakfast Casserole, making it irresistible.

Step 8: Bake to Perfection
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 30 minutes, then remove the foil and continue baking for an additional 15–20 minutes, or until the top is a nice golden brown. This step allows the casserole to puff up and achieve that perfect cafe-style look, inviting everyone for brunch.

Monte Cristo Breakfast Casserole Recipe FAQs

What type of bread is best for this casserole?

How should I store leftovers?
After enjoying your casserole, store any leftovers in an airtight container in the fridge for up to 3 days. When you’re ready to indulge again, simply reheat portions in the microwave or in the oven at 350°F until warmed through. This way, you can enjoy the comforting flavors without any fuss!

Can I freeze the Monte Cristo Breakfast Casserole?

What should I do if my casserole is too dry?
If you find the casserole has turned out dry after baking, it’s a good idea to ensure that all the bread was properly saturated with the egg mixture beforehand. You might also want to let it rest for a bit longer before baking next time. If you’re looking to rescuer the current batch, try drizzling a bit more maple syrup or melted butter over the top before serving, just to bring back some moisture and flavor!

Can I add vegetables or other proteins?
