Basic Ingredients
- 4 large croissants, torn into bite-sized pieces
- 8 large eggs
- 2 cups whole milk
- 2 cups shredded cheese (cheddar, Swiss, or your choice)
- 1 cup cooked ham or crispy bacon, chopped
- Salt and freshly ground black pepper, to taste
Instructions
- Prepare the croissants and protein: Tear the croissants into bite-sized pieces and chop the cooked ham or bacon. This forms the base and savory element of the casserole.
- Mix the custard: In a large bowl, whisk together eggs, milk, salt, and pepper until fully combined and slightly frothy. This mixture will soak into the croissants and create the creamy texture.
- Assemble the casserole: In a greased baking dish, layer the croissant pieces, ham or bacon, and half of the shredded cheese. Pour the egg and milk mixture evenly over the layers, then sprinkle the remaining cheese on top to create a delicious topping.
- Refrigerate overnight: Cover the baking dish tightly with plastic wrap and refrigerate for at least 8 hours or overnight. This allows the croissants to absorb the custard and flavors to meld.
- Bake the casserole: Remove the casserole from the refrigerator about 30 minutes before baking to take off the chill. Preheat your oven to 350°F (175°C). Bake uncovered for 45 to 55 minutes, or until the eggs are set, the top is golden brown, and a knife inserted in the center comes out clean.
- Serve: Let the casserole cool for a few minutes before slicing and serving. Enjoy warm for a hearty breakfast or brunch option.
Notes
- You can substitute the ham or bacon with sausage or keep it vegetarian by omitting the meat.
- Use day-old croissants for best texture and absorption.
- Add vegetables like spinach, bell peppers, or mushrooms for extra nutrition and flavor.
- Ensure the casserole is fully cooked by checking that the center is set and no longer jiggly.
- This recipe can be doubled for larger groups, just adjust the baking time accordingly.
