Step‑by‑Step Instructions for Monte Cristo Breakfast Casserole
Step 1: Preheat and Prepare the Baking Dish
Begin by preheating your oven to 350°F (175°C). While the oven warms up, generously grease a 9×13 inch baking dish with butter or cooking spray to prevent sticking. This will ensure that your Monte Cristo Breakfast Casserole has a crispy, golden exterior when it finishes baking.
Step 2: Cube the Bread
Cut the day-old white bread into bite-sized cubes, approximately one inch in size. Place half of the cubes into the prepared baking dish, spreading them evenly across the bottom. The bread will soak up the delicious custard mixture, forming the base of your casserole.
Step 3: Layer the Proteins and Cheese
Next, sprinkle a layer of diced ham, shredded turkey, and Swiss cheese over the bread cubes in the baking dish. This combination infuses rich, savory flavors into the Monte Cristo Breakfast Casserole, creating a delightful contrast that everyone will enjoy.
Step 4: Complete the Bread Layer
Add the remaining bread cubes on top of the ham, turkey, and cheese layers. Ensuring even coverage helps create a cohesive structure for the casserole, allowing each bite to have a blend of flavors and textures, making it a brunch favorite.
Step 5: Whisk the Custard Mixture
In a large mixing bowl, whisk together the eggs, milk, maple syrup, salt, and pepper until fully combined. This mixture will become the custard that binds your casserole together. Pour it evenly over the layered ingredients in the baking dish, allowing the bread to fully soak in the liquid.
Step 6: Add the Finishing Touches
Drizzle melted butter over the top of the assembled casserole for added richness and a beautifully browned finish. This step enhances the flavor while ensuring that the top develops a delectable, crispy texture as it bakes.
Step 7: Bake the Casserole
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 30 minutes to allow the casserole to set. After the initial baking time, remove the foil and continue baking for another 15-20 minutes, or until the top is golden brown and the center is firm to the touch.
Step 8: Cool and Serve
Once your Monte Cristo Breakfast Casserole is beautifully golden, take it out of the oven and let it cool for about 10 minutes. This resting time allows the flavors to meld and makes serving easier. Cut into squares and enjoy this delightful brunch dish with family and friends!

Monte Cristo Breakfast Casserole Recipe FAQs
How do I select the best bread for the casserole?
Absolutely! For the Monte Cristo Breakfast Casserole, day-old white bread is ideal as it absorbs the egg mixture better, preventing it from becoming soggy during baking. Look for bread with a sturdy crumb; avoid any with dark spots or significant signs of mold. If you’re in a pinch, a light toasting can also help with absorption.
How should I store leftovers of the casserole?
After enjoying your delicious Monte Cristo Breakfast Casserole, store any leftovers in an airtight container in the fridge for up to 3 days. Be sure it has cooled completely before sealing to keep it fresh and prevent sogginess.
Can I freeze the casserole?
Very! To freeze your Monte Cristo Breakfast Casserole, cut it into individual servings and place them in airtight containers or freezer bags. Make sure to push out any excess air to prevent freezer burn. It can be frozen for up to 1 month. When you’re ready to enjoy it again, simply thaw it overnight in the fridge before reheating.
What should I do if my casserole is too dry after baking?
If you find your casserole turns out dry, it might need more moisture in the egg mixture. Make sure you’re whisking enough milk into the eggs or even consider adding a splash more before baking. Always allow it to soak adequately for at least 15-30 minutes before going into the oven. Adding an extra drizzle of melted butter on top before baking helps improve the richness, so I recommend trying that too!
Are there any dietary considerations for pets or allergies?
Absolutely! The Monte Cristo Breakfast Casserole contains ingredients like eggs, dairy, and processed meats, which should be avoided for pets as they can cause digestive issues. For allergies, be sure to check each ingredient; if you have gluten sensitivities, consider using gluten-free bread, and for dairy intolerance, almond milk works beautifully as a substitute!
Can I make substitutions for the meats or cheese?
Very much so! Feel free to customize your Monte Cristo Breakfast Casserole by swapping out the ham for smoked turkey or even crispy bacon. You can also try different cheeses, such as Gruyere or cheddar for a bolder flavor. Adjust the ingredient quantities to your liking while keeping the base structure for the best results!
