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 the oven warms up, grab a 9×13 inch baking dish and gently grease it with cooking spray or a light coating of butter. This will ensure your Monte Cristo Breakfast Casserole lifts out easily after baking.
Step 2: Prepare the Bread
Take your day-old white bread and cut it into bite-sized cubes, aiming for roughly 1-inch pieces. Once cubed, scatter half of the bread cubes evenly across the bottom of the greased baking dish, creating a cozy, inviting base for your casserole.
Step 3: Layer the Meats and Cheese
Now, layer your savory ingredients! Spread the sliced ham and turkey evenly on top of the first half of the bread cubes. Follow this with a generous layer of shredded Swiss cheese. This delightful combination will create that classic Monte Cristo flavor we all love, so be sure to cover the bread well.
Step 4: Add Remaining Bread Cubes
Next, take the remaining bread cubes and pile them on top of the cheese. Make sure it’s spread evenly across the dish. This final bread layer will soak up all the tasty custard mixture you’re about to prepare, adding to the overall richness of the Monte Cristo Breakfast Casserole!
Step 5: Whisk Together the Custard
In a large mixing bowl, combine the beaten large eggs, milk, maple syrup, salt, and pepper. Whisk these ingredients together until well blended and fluffy, ensuring the mixture is uniform. The sweet and savory notes of this custard will tie everything together beautifully, so take your time with this step.
Step 6: Pour the Custard Over Layers
Carefully pour the egg mixture evenly over the layered bread, meat, and cheese. Allow the custard to soak into the bread, ensuring every piece is coated. If needed, use a spoon to gently press down the bread cubes, helping them absorb the rich flavors of the Monte Cristo Breakfast Casserole.
Step 7: Drizzle with Butter
Take your melted butter and drizzle it generously over the top of the casserole. This will create a golden, crispy crust while baking. The butter not only adds richness but also promotes browning, enhancing the visual appeal of your Monte Cristo Breakfast Casserole.
Step 8: Cover and Bake
Cover the casserole dish tightly with aluminum foil to retain moisture while baking. Place it into the preheated oven and bake for 30 minutes. This initial phase allows the flavors to meld beautifully together throughout the casserole.
Step 9: Uncover and Continue Baking
After 30 minutes, carefully remove the foil. Continue baking for an additional 15-20 minutes or until the casserole is puffed and golden brown on top. Keep an eye on it towards the end; the bubbling and sizzling will indicate when it’s ready to come out!
Step 10: Let it Rest
Once done, remove the casserole from the oven and let it rest for about 10 minutes. This resting time allows the Monte Cristo Breakfast Casserole to set, making it easier to slice and serve. The anticipation will build as the aromas waft through your kitchen!
Step 11: Slice and Serve
Finally, slice your warm Monte Cristo Breakfast Casserole into squares and serve! Consider dusting it with powdered sugar for a beautiful presentation alongside a drizzle of maple syrup. This dish is sure to impress from the first bite!

Monte Cristo Breakfast Casserole Recipe FAQs
How do I select the best bread for this casserole?

What if my casserole turns out soggy?
Don’t worry; a soggy casserole can happen! To prevent this, ensure your bread is day-old to allow more absorption of the egg mixture. If it does turn out soggy, you can try baking it a bit longer uncovered to help dry it off and create that desired crispy, golden crust.
Are there any allergy considerations I should be aware of?
