Ingredients
- 12 slices white or brioche bread, crusts removed if desired
- 8 slices deli ham
- 8 slices deli turkey
- 2 cups shredded Swiss cheese (or gruyère)
- 8 large eggs
- 2 cups whole milk
- ¼ cup heavy cream
- 1 tablespoon Dijon mustard
- 1 tablespoon maple syrup
- ½ teaspoon salt
- ¼ teaspoon black pepper
For Topping and Serving:
- 2 tablespoons melted butter
- 1 tablespoon powdered sugar (optional)
- Raspberry or strawberry preserves, for serving
- Optional: warm maple syrup
Preparation
Step 1:
Grease a 9×13-inch baking dish with butter or cooking spray. Cut the bread into quarters or halves if needed to fit the dish evenly.
Step 2:
Layer half of the bread slices on the bottom of the dish. Top with half the ham, half the turkey, and half the Swiss cheese. Repeat with the remaining bread, meat, and cheese to create two full layers.
Step 3:
In a large bowl, whisk together the eggs, milk, cream, Dijon mustard, maple syrup, salt, and black pepper. Pour the egg mixture evenly over the layered casserole, ensuring all the bread is soaked.
Step 4:
Cover tightly with foil or plastic wrap and refrigerate for at least 4 hours or overnight to allow the bread to absorb the custard.
Step 5:
Preheat the oven to 350°F (175°C). Remove the casserole from the fridge and let it come to room temperature for about 15–20 minutes. Drizzle melted butter over the top.
Step 6:
Bake uncovered for 40–45 minutes or until the top is golden brown and the center is set. Let rest for 5–10 minutes before slicing. Dust with powdered sugar and serve with raspberry preserves or syrup.
Variation
- Use croissants or challah bread for an even richer texture.
- Add a thin layer of raspberry jam between the bread and meat layers for more sweetness inside.
- Swap turkey for roast chicken or ham for bacon.
- Mix in ½ teaspoon nutmeg or a pinch of cayenne for a twist.
- Top with crushed cornflakes or breadcrumbs before baking for extra crunch.
Cooking Note
Letting the casserole soak overnight is key for the best texture and flavor. The bread needs time to absorb the egg mixture fully. Be sure not to underbake, it should puff slightly and set fully in the center. Cover with foil if the top browns too quickly.
Serving Suggestions
Serve this Monte Cristo Breakfast Casserole hot with a side of fresh fruit, crispy bacon, or a green salad for brunch. Drizzle with syrup or dollop with preserves for the full Monte Cristo experience. A dusting of powdered sugar adds visual appeal and sweetness. It also pairs wonderfully with orange juice, coffee, or a brunch mimosa.
Tips
- Use day-old bread or slightly dry slices so they absorb the custard better.
- For even slicing, let the casserole cool for 10 minutes before cutting.
- Make it in individual ramekins for personalized portions.
- Store leftovers covered in the fridge for up to 3 days and reheat in the oven or microwave.
- For a gluten-free version, use gluten-free sandwich bread and ensure all ingredients (like mustard and jam) are GF-certified.
