Monte Cristo Breakfast Casserole Ingredients
• Perfect for brunch gatherings or family breakfasts!
For the Casserole
- Sliced Ham – Gives a savory depth and protein boost; can be swapped with sliced roast beef or prosciutto if desired.

- Swiss Cheese – Melts to create a creamy texture; Gruyère or provolone can be used for a unique taste.

- Raspberry Preserves – Elevates the dish with a fruity touch; other fruit preserves like strawberry or apricot can be lovely alternatives.
Step‑by‑Step Instructions for Monte Cristo Breakfast Casserole
Step 1: Preheat the Oven
Begin your Monte Cristo Breakfast Casserole by preheating your oven to 350°F (175°C). This ensures that your casserole will bake evenly, creating a beautifully golden top. As the oven warms, gather your other ingredients to streamline the next steps.
Step 2: Prepare the Baking Dish
Next, grease a 9×13-inch baking dish using cooking spray or butter, ensuring even coverage to prevent sticking. Arrange slices of your chosen day-old bread in the bottom of the dish, covering the surface completely. This forms a sturdy, custardy base for your casserole.
Step 3: Layer the Meats and Cheese
Now it’s time to layer your flavors! Begin by spreading a generous layer of sliced ham over the bread, followed by turkey slices and a hearty sprinkle of Swiss cheese. Ensure the ingredients are evenly distributed for balanced bites, creating a savory layer that’s sure to delight.
Step 4: Whisk the Custard Mixture
In a large bowl, whisk together your eggs, milk, and a pinch of salt and pepper until fully combined. This custard will soak into the layers of your Monte Cristo Breakfast Casserole. Once smooth, carefully pour the custard mixture over the layered ingredients, making sure to cover everything evenly.
Step 5: Refrigerate to Soak
To enhance the flavors, cover the baking dish with plastic wrap and refrigerate for at least one hour. This allows the bread to soak up the savory custard, leading to a moist and flavorful casserole. If time permits, letting it soak overnight will deepen the flavor even more.
Step 6: Bake the Casserole
After soaking, remove the dish from the refrigerator and uncover it. Place your casserole in the preheated oven and bake for 45 minutes or until the top is puffed and golden brown. You’re looking for a crisp top with gooey melted cheese underneath, which is a sign of perfection.
Step 7: Dust and Serve
Once baked, remove the casserole from the oven and allow it to cool slightly. To add a touch of sweetness, sprinkle powdered sugar over the top before serving. Pair your warm Monte Cristo Breakfast Casserole with raspberry preserves on the side for a delightful contrast that will impress your guests!

Monte Cristo Breakfast Casserole Recipe FAQs
How do I choose the best bread for this casserole?
Absolutely! The best bread for your Monte Cristo Breakfast Casserole is day-old sandwich bread, brioche, or challah. These types are soft enough to soak up the rich custard without falling apart. If you’re using fresh bread, leave it out to dry for a few hours. Avoid crusty bread, as it won’t absorb the custard well.
What is the best way to store leftovers?
Very easily! Store any leftover casserole in an airtight container in the fridge for up to 3 days. Simply reheat individual portions in the microwave for a quick breakfast, or pop it back in the oven at 350°F (175°C) until warmed through.
Can I freeze the casserole?
Yes, you can! For longer storage, freeze the casserole before baking. Wrap it tightly in plastic wrap and then in aluminum foil to keep it airtight. It will stay fresh for up to 3 months. When you’re ready to enjoy it, thaw overnight in the fridge and bake as directed, covered with foil for even heating.
What if my casserole turns out dry?
If your Monte Cristo Breakfast Casserole turns out dry, it may be due to overbaking or if the bread wasn’t stale enough to soak up enough custard. To fix this, you can try adding a little warm milk or cream while reheating it to hydrate the dish. For next time, ensure the bread is slightly stale and keep a close eye on the baking time.
Is this casserole suitable for a gluten-free diet?
Absolutely! You can make a gluten-free Monte Cristo Breakfast Casserole by substituting regular bread with gluten-free bread options. Many gluten-free breads work wonderfully, providing the same custardy texture without the gluten.
Can I prepare the casserole the night before?
Yes, you can! In fact, I often recommend it for maximum flavor. Assemble your casserole the night before, cover it with plastic wrap, and refrigerate it. This allows the flavors to meld beautifully, and when breakfast time comes, all you need to do is pop it in the oven to bake.
