Once baked, the croissants turn golden and crisp on top while staying soft and custardy underneath. The final touch is a silky black pepper gravy that takes every bite over the top.

How to Make the Egg Custard for Breakfast Bake

Add all ingredients listed under the egg custard to a bowl. Whisk until smooth and fully combined. Set aside while you prepare the remaining components.

How to Make Creamy Black Pepper Gravy

Add the unsalted butter to a pan over medium-low heat. Once melted, sprinkle in the flour and whisk until smooth and fully incorporated.

Slowly stream in the heavy cream while continuously whisking. As you whisk, the gravy will begin to thicken and come together.

Once thick enough to coat the back of a spoon, remove from heat and season with salt and black pepper. Set aside until ready to serve.

How to Assemble Ham and Cheese Croissants

Slice the croissants lengthwise and stuff generously with ham, gruyere cheese, mozzarella cheese, and cooked bacon. Close each croissant and cut in half. Repeat until all croissants are filled and sliced.

How to Assemble and Bake Croissant Breakfast Casserole

Preheat the oven to 350F.

Evenly arrange the ham and cheese croissants in an 8×11 baking dish. Fill in any gaps with any remaining ham, bacon, mozzarella, and gruyere cheese.

Slowly pour the shallot and chive infused egg custard evenly over the croissants, making sure everything is well coated. Transfer to the oven and bake for 25 to 30 minutes, or until golden brown and the custard is fully set.

How to Serve Croissant Breakfast Bake

Serve the bake warm with a generous side of black pepper gravy for spooning over the top. This dish pairs perfectly with fresh fruit, a simple green salad, or a hot cup of coffee for a complete brunch spread.
