How to Make Monte Cristo Breakfast Casserole
-
Preheat the oven to 175°C. This initial step ensures your casserole cooks evenly and achieves that perfect golden-brown top. Lightly coat the interior of a 20×20 cm or 23×23 cm baking dish with non-stick cooking spray, setting it aside for later.
-
Whisk together the eggs, fat-free half & half, Dijon mustard, ground nutmeg, salt, and black pepper in a large bowl. Aim for a smooth, creamy mixture that blends all the flavors together beautifully.
-
Add the cubed French bread to your egg mixture and stir gently. Make sure each piece of bread is coated evenly, allowing it to soak up the rich custard for a heavenly texture.
-
Fold in the diced ham and shredded Swiss cheese slowly. This helps to distribute the savory ham and gooey cheese throughout the casserole, ensuring every bite is a delicious dream.
-
Pour the entire mixture into the prepared baking dish, spreading it evenly. Bake for approximately 40 minutes, or until the edges turn golden brown and the cheese is perfectly melted and bubbly.
-
Remove the casserole from the oven and allow it to rest for several minutes before slicing. This helps the layers settle a bit, making each slice easier to serve. Enjoy warm, optionally with a dollop of raspberry preserves for an extra touch of sweetness!
Optional: Top with fresh herbs for a pop of color and flavor.

Chef's Helpful Tips
- For the Monte Cristo Breakfast Casserole, using stale bread is key as it absorbs the custard beautifully, enhancing the dish’s overall texture.
- Whisk the egg mixture thoroughly to combine all the flavors uniformly before adding in the bread; this ensures a creamy and cohesive base.
- When adding the cheese and ham, fold gently to avoid breaking the bread pieces, which will create an uneven texture in the casserole.

Monte Cristo Breakfast Casserole Recipe FAQs
How do I select the right bread for the casserole?
Absolutely! For this Monte Cristo Breakfast Casserole, I recommend using stale French bread for the best texture. Fresh bread may become too soggy, whereas stale bread soaks up the custard beautifully without losing its shape. Look for bread that’s firm with a light crust, ideally a day or two old.
How can I store leftovers of the casserole?
Very simple! Store any leftover casserole in an airtight container in the fridge for up to 3 days. This keeps the dish fresh and ready to reheat. When you’re ready to enjoy it again, just pop it in the microwave or oven until heated through.
Can I freeze Monte Cristo Breakfast Casserole?
Absolutely! For freezing, wrap individual portions tightly in plastic wrap, then wrap those in aluminum foil. This method prevents freezer burn and keeps them fresh for up to 2 months. Just remember to label them with the date so you don’t lose track!
How do I properly thaw frozen portions of the casserole?
To thaw frozen portions, simply transfer them to the fridge overnight before you plan to reheat them. This gentle thawing method helps maintain the texture. Once thawed, preheat your oven to 175°C and reheat the casserole until it’s warmed through, which typically takes about 20-25 minutes.
Is this casserole suitable for dietary restrictions, like allergies?
Yes, it can be! You can easily adapt the Monte Cristo Breakfast Casserole to suit various dietary needs. For those with lactose intolerance, consider using a dairy-free milk and cheese alternative. Additionally, if you have a gluten allergy, replace the French bread with a gluten-free substitute. Always check the labels of processed ingredients for hidden allergens, especially if you’re serving others!
What can I do if my casserole turns out too dry?
If you find your casserole a bit dry after baking, don’t fret! You can drizzle a little extra half & half or milk over the top of the slices before reheating them. This will help restore some moisture. Another tip is to ensure the egg mixture has properly saturated the bread before baking, as this helps keep the casserole moist and creamy throughout.
