How to Make Monte Cristo Breakfast Casserole
-
Prepare the Dish: Grease a 9×13 inch baking dish with butter or non-stick spray. This will ensure easy release and cleanup after baking your delicious casserole.
-
Layer the Bread and Meats: Arrange half of the bread cubes evenly in the bottom of the prepared dish. Top with half the deli ham, followed by turkey, and sprinkle half of the shredded Swiss and Gruyère cheeses over everything. Add the remaining bread cubes on top for a delicious multi-layered effect.
-
Whisk the Custard: In a large bowl, whisk together the eggs, whole milk, heavy cream, Dijon mustard, vanilla extract, salt, and pepper until well combined. This custard will soak into the bread for a luscious texture.
-
Soak the Bread: Pour the egg mixture evenly over the layered bread in the baking dish. Gently press down on the bread to help it absorb the custard. Cover it and refrigerate for at least 30 minutes, or better yet, let it soak overnight for richer flavors.
-
Preheat the Oven: Preheat your oven to 375°F (190°C). If you refrigerated the casserole overnight, let it sit at room temperature for 30 minutes before baking; this helps it cook more evenly.
-
Bake the Casserole: Uncover the dish and bake for 50-60 minutes, or until the top is golden brown and puffed. A knife inserted into the center should come out clean, signaling it’s ready to enjoy!
-
Cool and Serve: Let the casserole cool for 10 minutes before slicing into squares. Dust generously with powdered sugar, and serve warm alongside raspberry jam for a delightful contrast of sweet and savory.
Optional: Serve with fresh berries for an extra burst of flavor!
