The Monte Cristo Breakfast Casserole brings together all those classic flavors you love in a Monte Cristo sandwich, but in a fun, easy-to-make casserole form. It’s packed with ham, turkey, melted cheese, and a touch of sweetness from jam or preserves, all baked up in a fluffy egg and bread base. It feels like a special breakfast treat that’s also super satisfying and comforting.
I really enjoy making this casserole when I want a meal that can feed a crowd without spending a ton of time in the kitchen. One of my favorite parts is that you can prepare it the night before and just pop it in the oven in the morning. The combination of salty meat and gooey cheese with a little sweetness from the jam cracks me up every time—it’s like breakfast and dessert rolled into one! I like to add a dusting of powdered sugar on top before serving because it gives it that classic Monte Cristo look and a hint more sweetness.
Serving this casserole warm with some fresh fruit or a simple salad on the side makes it feel like a weekend brunch everyone will enjoy. It’s the kind of breakfast that disappears quickly, and I’m always happy to make it again. If you love a good sweet-and-salty breakfast, this casserole is a go-to that never disappoints!
Key Ingredients & Substitutions
White Bread: Use day-old or slightly stale bread for better soaking. If you want a healthier option, whole wheat or sourdough bread works well too.
Ham and Turkey: These give the casserole a classic Monte Cristo flavor with salty and savory notes. You can swap turkey for chicken or use vegetarian deli slices if you want a meat-free version.
Swiss Cheese: This cheese melts beautifully and adds a mild nuttiness. If unavailable, Gruyère or mozzarella are great alternatives.
Eggs and Milk: They form the custard base that soaks into the bread. For dairy-free needs, try almond or oat milk and egg replacers, though the texture might be slightly different.
Jam: Raspberry or strawberry jam adds that iconic sweet touch. You can use any berry jam, or try apricot for a different taste.
How Can I Make Sure the Bread Absorbs the Egg Mixture Well?
Getting the bread fully soaked with the egg custard is key for a creamy casserole. Here’s how to do it right:
- Use bread that isn’t too fresh; older bread soaks better without getting mushy.
- After pouring the egg mixture over the bread, gently press down with a spatula to help it sink in.
- Let the casserole sit for 10-15 minutes before baking to give the bread time to absorb the liquid.
- Don’t overfill with egg mixture to avoid soggy spots—just enough to coat the bread cubes.
Equipment You’ll Need
- 9×13-inch baking dish – perfect size for this casserole to cook evenly and hold all the layers.
- Mixing bowl – you’ll whisk the eggs and milk together easily here.
- Whisk – helps blend the egg mixture smoothly without lumps.
- Measuring cups and spoons – for accurate ingredient amounts and balanced flavors.
- Spatula or spoon – great for pressing the bread cubes down to soak up the egg mixture well.
Flavor Variations & Add-Ins
- Swap ham and turkey for cooked sausage or bacon for a smoky, hearty twist.
- Try replacing Swiss cheese with sharp cheddar or pepper jack for a stronger or spicier flavor.
- Add diced bell peppers or sautéed mushrooms for a veggie boost and extra texture.
- Mix in a teaspoon of dried herbs like thyme or rosemary for a fragrant herbal note.

How Much Time Will You Need?
This recipe takes about 15 minutes to prepare and assemble. Then, you’ll bake it for 35 to 45 minutes until golden and puffy. Total time is around 50 to 60 minutes. You can also prepare it the night before and bake it fresh in the morning.
Step-by-Step Instructions:
1. Prep and Assemble the Casserole:
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish. Spread the cubed bread evenly in the dish. Sprinkle the chopped ham, turkey, and Swiss cheese over the bread cubes.
2. Make the Egg Mixture:
In a medium bowl, whisk together the eggs, milk, Dijon mustard, salt, pepper, and garlic powder until smooth. Pour this mixture evenly over the bread and meat layers. Press gently on the bread to help it soak up the custard.
3. Bake and Serve:
Drizzle the melted butter on top. Bake the casserole for 35 to 45 minutes, until it’s puffed and golden and a knife comes out clean from the center. If you like, crack one or two eggs on top during the last 5 minutes of baking and bake until the eggs are cooked to your preference.
Once baked, let it cool for a few minutes. Sprinkle powdered sugar on top, serve with your favorite raspberry or strawberry jam, and garnish with fresh thyme or parsley if you like. Enjoy the wonderful mix of sweet and savory flavors!
Can I Make This Casserole Ahead of Time?
Absolutely! Assemble the casserole the night before, cover it tightly, and refrigerate. Bake it fresh in the morning—this helps the bread absorb the custard well and makes busy mornings easier.
What Can I Use Instead of White Bread?
You can substitute with whole wheat, sourdough, or even brioche for a richer flavor. Just make sure the bread is slightly stale or toasted so it soaks up the egg mixture without getting too soggy.
How Should I Store Leftovers?
Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through to keep the casserole’s texture intact.
Can I Add Vegetables to This Casserole?
Yes! Diced bell peppers, mushrooms, or spinach make great additions. Sauté them first to remove excess moisture, then add them with the meat and cheese for extra flavor and nutrition.
