How to Make Monte Cristo Breakfast Casserole

Step 1: Preheat and Prepare

First things first, let’s get that oven preheating! Set it to 350°F (175°C). While it warms up, grab your 20×20 cm or 23×23 cm baking dish and give it a light coat with non-stick cooking spray. This step ensures every delicious morsel of your Monte Cristo Breakfast Casserole slides out smoothly. Trust me, nobody likes a casserole that sticks!

Step 2: Whisk the Egg Mixture

In a large bowl, combine the eggs, fat-free half & half, Dijon mustard, ground nutmeg, salt, and black pepper. It’s important to whisk this mixture thoroughly, as it creates the creamy base of your casserole. The Dijon mustard and nutmeg add unexpected depth, so take your time to mix well until everything is beautifully blended. Your kitchen will start to smell heavenly!

Step 3: Combine Bread with Egg Mixture

Now, it’s time to add the star of the show: stale French bread! Gently fold the cubed bread into the egg mixture, ensuring each piece is coated equally. Be careful not to squish the bread too much; we want it to soak up that flavorful liquid without turning into mush. This step is all about embracing a light touch for the ultimate texture!

Step 4: Add Ham and Cheese

Next up, it’s time to bring in those savory heroes: the diced ham and shredded Swiss cheese. Toss them into the bread mixture, folding carefully to distribute everything evenly. The melted cheese will create pockets of gooey goodness throughout the casserole, while the ham adds that classic Monte Cristo vibe. You’re almost ready to bake this delightful dish!

Step 5: Bake to Perfection

Pour the entire mixture into your prepared baking dish, spreading it out evenly. Pop it in the oven for about 40 minutes. Keep an eye on it; the edges should turn a beautiful golden brown, and the cheese will be bubbling away. That’s when you’ll know it’s baked to perfection. Feel free to use a toothpick to check doneness—if it comes out clean, you’re all set!

Step 6: Cool and Serve

Once it’s out of the oven, let the casserole cool for a few minutes before slicing. This resting time makes cutting so much easier! Serve warm, and for that extra touch of indulgence, consider a dollop of raspberry preserves on the side. It beautifully contrasts the savory and adds a burst of flavor!

Tips for Success

Make sure to use stale French bread—fresh bread can lead to a mushy texture.
Prep the casserole the night before, refrigerate, and pop it in the oven in the morning!
Add herbs like thyme or parsley for an aromatic touch.
Let the casserole rest before serving to ensure clean slices.
Experiment with different cheeses for a unique flavor twist!

Equipment Needed

Baking dish (20×20 cm or 23×23 cm): A standard casserole dish works well; any oven-safe dish can do the job!
Mixing bowls: A couple of medium-sized bowls will help keep your ingredients organized.
Whisk: Use a fork if you don’t have a whisk handy; both will blend your egg mixture nicely.
Spatula: A rubber or silicone spatula is perfect for folding ingredients without squishing them.
Measurement cups and spoons: Essential for accuracy, but you can eyeball it if you’re comfortable!

Variations of Monte Cristo Breakfast Casserole

Turkey Monte Cristo: Swap out the ham for diced turkey for a leaner twist that maintains that classic flavor.
Veggie Delight: Add sautéed spinach, bell peppers, or mushrooms to create a delicious vegetarian option packed with vitamins.
Cheese Lovers: Experiment with different cheeses like Gruyère or cheddar to bring a unique taste to your casserole.
Sweet & Savory: Incorporate a layer of thinly sliced strawberries or apples to balance the richness of the dish.
Low-Carb Option: Replace bread with cauliflower rice for a keto-friendly version, keeping the flavors intact.
