Monte Cristo Breakfast Casserole has quickly become a weekend favourite in my house, especially when mornings are a little slower and the kids demand something comforting (and dippable!) before the day’s chaos begins. This dish is a nostalgic nod to the classic Monte Cristo sandwich but transformed into a cozy, shareable casserole that fills the kitchen with buttery, melty aromas. It’s the kind of recipe that invites everyone to gather round the table, which is exactly what food means to me—a way to connect, to slow down, and to celebrate simple pleasures with those you love.

Why You’ll Love This Monte Cristo Breakfast Casserole
What makes this Monte Cristo Breakfast Casserole stand out is its perfect balance of indulgence and ease. The layers of ham, cheese, and custardy bread soak up flavours that remind me of lazy Sunday mornings back in England, but with a modern twist that suits busy family life here in San Diego. It’s a dish that feels special yet is simple enough to assemble the night before, which is a lifesaver when mornings are hectic. Plus, the crispy edges and soft center create a texture contrast that even my little ketchup-loving dipper can’t resist.
Ingredients You’ll Need for This Monte Cristo Breakfast Casserole
The key to this dish lies in selecting the right ingredients—fresh bread with a sturdy crumb, good-quality ham, and sharp cheese all make a huge difference. I’ve found that using day-old brioche or challah gives the perfect sponge-like texture after soaking in the egg mixture. Growing up watching my grandmother fuss over every ingredient, I learned that even simple dishes shine brightest when made with care and the best staples you can find.
- 8 cups cubed brioche or challah bread (preferably day-old)
- 1 pound sliced deli ham, chopped
- 2 cups shredded Gruyère or Swiss cheese
- 6 large eggs
- 2 cups whole milk
- 1/4 cup heavy cream
- 2 tablespoons Dijon mustard
- 1 tablespoon granulated sugar
- 1 teaspoon vanilla extract
- 1/2 teaspoon salt
- 1/4 teaspoon freshly ground black pepper
- Butter or non-stick spray for greasing
If you want to swap out ingredients, turkey or chicken breast make a lighter alternative to ham, and you can try a milder cheese like mozzarella if you prefer. For a dairy-free version, almond or oat milk works well, and coconut cream can replace heavy cream.

Instructions
- Preheat your oven to 350°F (175°C) and generously grease a 9×13-inch casserole dish with butter or non-stick spray.
- In a large bowl, whisk together eggs, milk, heavy cream, Dijon mustard, sugar, vanilla extract, salt, and pepper until smooth and well combined. This mixture is your custard base, so take a moment to enjoy the fragrant vanilla mingling with the mustard’s subtle bite.
- Layer half of the cubed bread evenly in the prepared dish. Sprinkle half the chopped ham and shredded cheese over the bread.
- Add the remaining bread cubes on top, followed by the rest of the ham and cheese. The layering ensures every bite has a balance of savoury and melty goodness.
- Pour the custard mixture evenly over the casserole, pressing down gently with a spatula to help the bread soak up the liquid. Cover with foil and refrigerate for at least 4 hours or overnight. I love this step because it means you can prepare the night before and wake up to a breakfast ready to bake.
- Remove the casserole from the fridge about 30 minutes before baking to take the chill off. Then bake covered for 40 minutes.
- After 40 minutes, remove the foil and bake for an additional 15 minutes until the top is golden and crispy, and the custard is set in the middle.
- Let the casserole rest for 5-10 minutes before serving to allow it to firm up slightly, making it easier to slice and serve.
