Monte Cristo Breakfast Casserole Ingredients
For the Casserole
- Eggs – Provide structure and moisture; use whole eggs for richness or egg whites for a lighter version.
- Cheese – Adds creaminess and flavor; Swiss or Gruyère are classic choices, while cheddar offers a sharper taste.
- Ham – Offers savory depth and protein; substitute with turkey or a plant-based alternative for a lighter or vegetarian option.
- Bread – The base of the casserole; brioche or challah add a sweet touch, whereas whole grain provides a healthier option.
- Dijon Mustard – Adds tanginess; consider whole grain mustard for a different flavor profile or omit for a milder effect.
- Raspberry Preserves – Provides sweetness and a fruity contrast; swap for any fruit preserves or fresh berries according to preference.
Step‑by‑Step Instructions for Monte Cristo Breakfast Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature will ensure that your Monte Cristo Breakfast Casserole bakes evenly, creating a fluffy texture. While the oven heats, gather all your ingredients and greased a 9×13-inch baking dish to prepare for layering.
Step 2: Whisk the Egg Mixture
In a large mixing bowl, whisk together a dozen eggs and a few tablespoons of Dijon mustard until the mixture is uniform in color and texture. You should achieve a smooth blend without any visible egg whites. Set this mixture aside momentarily, as it will coat the casserole later, offering a delightful savory flavor.
Step 3: Layer the Ingredients
Take your greased baking dish and evenly layer cubed bread at the bottom; brioche or challah works beautifully here. Then, sprinkle diced ham and shredded cheese over the bread layer. Make sure to distribute these ingredients evenly, so every bite of your Monte Cristo Breakfast Casserole is bursting with flavor.
Step 4: Pour the Egg Mixture
Now, slowly pour the egg mixture over your layered ingredients, ensuring it seeps through the bread and coats each piece nicely. This soaking process allows the bread to absorb the flavorful liquids. Let the entire assembly sit for at least 15 minutes to ensure everything marries together.
Step 5: Bake the Casserole
Place your prepared casserole in the preheated oven and bake for 30 to 40 minutes. Watch for a puffed and set appearance, indicating it’s done. A light golden-brown top with a slightly firm texture should be your visual cue that your Monte Cristo Breakfast Casserole is ready to come out of the oven.
Step 6: Drizzle with Raspberry Preserves
Once out of the oven, let your Monte Cristo Breakfast Casserole rest for about 5 to 10 minutes. This resting period helps firm it up, making slicing easier. Before serving, drizzle raspberry preserves over the top for a sweet contrast that will elevate its wonderful flavors and add a lovely finishing touch.

Make Ahead Options
These Monte Cristo Breakfast Casserole are perfect for busy home cooks looking to save time! You can prepare the entire assembly, covering the layered ingredients with the egg mixture, up to 24 hours in advance—just be sure to refrigerate it tightly covered. This soaking allows the bread to absorb all those delicious flavors while keeping it moist. If you prefer more flexibility, you can also bake the casserole completely and store leftovers in an airtight container in the refrigerator for up to 3 days. To finish, simply reheat individual portions in the microwave or bake in the oven until warmed through; trust me, it’s just as delicious!
