Step‑by‑Step Instructions for Monte Cristo Breakfast Casserole
Step 1: Prepare Bread Base
Begin by cubing your chosen crusty bread, such as ciabatta or sourdough, into bite-sized pieces. Lightly grease a 9×13-inch baking dish with cooking spray or butter, then evenly distribute the bread cubes across the bottom. Make sure to cover the base thoroughly to create a sturdy foundation for the Monte Cristo Breakfast Casserole.
Step 2: Mix Egg Mixture
In a large mixing bowl, crack open 8 large eggs and whisk them vigorously until well combined. Add in Dijon mustard, salt, and pepper to taste, continuing to whisk until fully blended. The egg mixture should be smooth and slightly frothy, creating a rich foundation that will bind the casserole together beautifully.
Step 3: Layer Ingredients
Sprinkle the diced ham evenly over the bread cubes in the baking dish. Next, add a generous layer of your choice of cheese, either Swiss or Gruyère, ensuring even distribution to melt beautifully during baking. Carefully pour the whisked egg mixture over the layers, using a spatula to ensure even coverage across the bread, ham, and cheese.
Step 4: Soak & Refrigerate
Cover the dish with plastic wrap or aluminum foil and let the casserole soak for at least 15 minutes at room temperature. For even better flavor, refrigerate it overnight, allowing the bread to absorb the egg mixture fully, resulting in a moist and delicious Monte Cristo Breakfast Casserole.
Step 5: Bake
Preheat your oven to 350°F (175°C). Once heated, place the casserole in the oven and bake for about 40 minutes. Keep an eye on it; the top should become golden brown with a slight puff and a firm set in the middle, which indicates that the eggs are fully cooked.
Step 6: Finish & Serve
Once baked to perfection, remove the casserole from the oven and let it sit for about 5 to 10 minutes to cool slightly. Drizzle raspberry preserves over the top just before serving to add a delightful touch of sweetness that perfectly complements the savory flavors of the Monte Cristo Breakfast Casserole.

How to Store and Freeze Monte Cristo Breakfast Casserole
Fridge: Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the microwave or oven until warmed through for a quick breakfast option.

Reheating: Thaw overnight in the refrigerator before reheating. Bake in a preheated oven at 350°F (175°C) for about 20 minutes, or until heated evenly.

Expert Tips for Monte Cristo Breakfast Casserole
-
Use Stale Bread: Allow your bread to sit out for a few hours or use day-old bread for optimal absorption of the egg mixture and to prevent sogginess.
-
Cool Before Slicing: Let the casserole settle for 5 to 10 minutes after baking. This helps ensure clean slices and prevents it from falling apart when you serve.
-
Careful with Baking: Keep an eye on the casserole while it bakes; if the top browns too quickly, cover it loosely with foil to avoid burning while the eggs finish cooking.
-
Experiment with Substitutions: Feel free to swap out ham for bacon or sausage, and mix in veggies like spinach for added nutrition in your Monte Cristo Breakfast Casserole.
-
Make Ahead: Prepare the casserole the night before and refrigerate it. This allows the flavors to meld beautifully, making your morning hassle-free!
Make Ahead Options
These Monte Cristo Breakfast Casserole preparations are a game changer for busy cooks!

On the day of serving, just preheat your oven to 350°F (175°C) and bake for about 40 minutes until golden and set.

Monte Cristo Breakfast Casserole Recipe FAQs
How do I choose the best bread for this casserole?
When selecting bread, aim for a slightly stale, crusty loaf like ciabatta or sourdough. A day-old loaf is ideal, as it allows the egg mixture to absorb better, enhancing texture without getting soggy.
How should I store leftover Monte Cristo Breakfast Casserole?
Absolutely! Store any leftovers in an airtight container in the refrigerator for up to 3 days. Simply reheat in the microwave or oven until warmed through.
Can I freeze this casserole?
Yes, you can freeze the casserole! After baking, allow it to cool completely, then cut it into individual portions. Wrap each portion tightly in plastic wrap and then in aluminum foil. It can be frozen for up to 2 months. When you’re ready to enjoy, thaw overnight in the fridge, then reheat in a preheated oven at 350°F (175°C) for about 20 minutes.
What should I do if my casserole is too soggy?
If your casserole turns out soggy, it may be due to using overly fresh bread or too much liquid. To prevent this, always use slightly stale bread. If it’s already baked, consider serving it with a sprinkle of fresh herbs or a dollop of cream to balance the texture.
Is this recipe suitable for special diets?
Very much so! If you’re looking for lighter options, substitute ham with turkey or chicken, and consider using gluten-free bread for a gluten-free version. Plus, if anyone in your household has allergies, skip the cheese or use a dairy-free alternative.

For optimal flavor infusion, let your Monte Cristo Breakfast Casserole soak for at least 15 minutes at room temperature. For even deeper flavor, refrigerate it overnight. This soaking time is crucial for the bread to absorb the savory egg mixture beautifully.
