Step‑by‑Step Instructions for Monte Cristo Breakfast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While that warms up, grab a 9×13-inch baking dish and lightly grease it with butter or non-stick spray. This will prevent your Monte Cristo Breakfast Casserole from sticking and ensure it comes out perfectly golden brown.
Step 2: Prepare the Bread
Cut the 8 slices of bread into cubes, aiming for roughly 1-inch pieces for even cooking. Spread half of the bread cubes evenly at the bottom of the greased baking dish, creating a solid foundation for the casserole. It’s best to use day-old bread, as it absorbs the egg mixture beautifully.
Step 3: Add the First Layer of Ham and Cheese
Layer half of the 8 slices of ham on top of the bread cubes, ensuring it covers the base evenly. Next, sprinkle half of the 1 ½ cups of shredded Swiss cheese over the ham, allowing the rich, creamy cheese to meld with the savory flavors. This layer adds a delightful taste and texture to your Monte Cristo Breakfast Casserole.
Step 4: Whisk the Egg Mixture
In a large bowl, crack 6 large eggs and whisk them together. Add in 1 ½ cups of milk, 2 tablespoons of maple syrup, 1 teaspoon of mustard, salt, and pepper. Mix until well combined, ensuring all ingredients are evenly distributed for that perfect custardy texture throughout the casserole.
Step 5: Pour Half of the Egg Mixture
Pour half of the egg mixture over the layered bread, ham, and cheese in the baking dish. Gently press down on the layers with a spatula to help them absorb the liquid. This step is crucial as it allows the flavors of the Monte Cristo Breakfast Casserole to blend beautifully as it bakes.
Step 6: Complete the Layering
Repeat the layering process by adding the remaining bread cubes followed by the rest of the ham and cheese. Then, pour the remaining egg mixture over the top. Just like before, press down to ensure everything mingles and absorbs the delicious custard, enriching each bite of your Monte Cristo Breakfast Casserole.
Step 7: Bake the Casserole
Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes. This initial cover helps cook the casserole evenly. After 30 minutes, remove the foil and continue baking for an additional 15-20 minutes, or until the top is set and golden brown, signaling that it’s perfectly cooked.
Step 8: Cool and Serve
Once baked, remove the Monte Cristo Breakfast Casserole from the oven and let it cool for about 10 minutes. This resting time not only makes slicing easier but also allows the flavors to settle. Serve warm, perhaps with an extra drizzle of maple syrup for that sweet touch!

Make Ahead Options
These Monte Cristo Breakfast Casserole preparations are a game-changer for busy mornings! You can assemble the casserole up to 24 hours in advance by layering the bread, ham, and cheese, then pouring the egg mixture over the top. Cover it tightly with plastic wrap and refrigerate to keep everything fresh. This method not only saves time but also allows the flavors to meld beautifully overnight. When you’re ready to serve, simply bake the casserole straight from the fridge, adding an extra 5-10 minutes to the cooking time to ensure it’s heated through. Just imagine enjoying a delightful homemade breakfast with minimal morning effort!

Monte Cristo Breakfast Casserole Recipe FAQs
How do I choose the right bread for the casserole?
Absolutely! For the best texture, I recommend using day-old bread, as it absorbs the egg mixture more efficiently, preventing sogginess. Look for a crusty bread like sourdough or French bread for an added flavor boost and delightful crunch.
How should I store leftover Monte Cristo Breakfast Casserole?
To keep your casserole fresh, wrap it tightly in plastic wrap or place it in an airtight container. It will last in the fridge for up to 3 days. When you’re ready to enjoy, just reheat slices in the microwave or oven for a quick and delicious breakfast.
Can I freeze Monte Cristo Breakfast Casserole? How?
Absolutely! To freeze, first let the casserole cool completely. Wrap it tightly in plastic wrap, followed by aluminum foil to protect it from freezer burn. It can be frozen for up to 3 months. To reheat, thaw in the refrigerator overnight and bake at 350°F (175°C) for about 20-25 minutes until warmed through.
What should I do if my casserole turns out soggy?
Very! If your casserole comes out too soggy, it may be due to using fresh bread instead of day-old bread. Another tip is to ensure you distribute the egg mixture evenly. To fix an overly wet casserole next time, try covering and baking it for a bit longer until most of the excess moisture is absorbed.
Is this casserole suitable for individuals with dairy allergies?
Yes, indeed! You can easily modify the recipe to be dairy-free. Substitute regular milk with almond milk or coconut milk, and use dairy-free cheese alternatives. Be sure to check the labels on all processed ingredients to avoid dairy.
How can I customize the Monte Cristo Breakfast Casserole?
The more the merrier! You can personalize it by substituting the ham for crispy bacon or turkey for a leaner option. For extra sweetness, try adding sliced apples or even a handful of berries. Feel free to mix in vegetables like spinach or bell peppers to boost the nutrition content and flavor!
