How to Make Overnight Croissant Breakfast Casserole
Ready to get started? Here’s how you can whip up this delightful Overnight Croissant Breakfast Casserole.
Ingredients
- 8 croissants, torn into pieces
- 6 large eggs
- 2 cups milk
- 1 cup shredded cheese (such as cheddar or Swiss)
- 1/2 cup cooked bacon or sausage, crumbled
- 1/2 cup diced vegetables (like bell peppers and onions)
- 1/4 cup sugar
- 1 teaspoon vanilla extract
- Salt and pepper to taste
Directions
- Prep the Baking Dish: Start by greasing a baking dish with butter or cooking spray. This will help prevent sticking and make cleanup easier.
- Arrange the Croissants: Tear the croissants into bite-sized pieces and arrange them evenly in the greased baking dish.
- Make the Egg Mixture: In a large bowl, whisk together the eggs, milk, sugar, vanilla extract, salt, and pepper until fully combined.
- Soak the Croissants: Pour the egg mixture over the torn croissants, using a spatula or your hands to gently press down so that all the pieces soak up the custard.
- Add Toppings: Sprinkle the shredded cheese, crumbled bacon (or sausage), and diced vegetables evenly over the soaked croissants.
- Refrigerate Overnight: Cover the baking dish with plastic wrap or foil and refrigerate overnight. This step allows the flavors to meld together beautifully.
- Bake: The next morning, preheat your oven to 350°F (175°C) and bake the casserole for 45-50 minutes, or until it is set and has a golden-brown top.
- Cool: Let it cool slightly before serving. This will help it hold together when you cut into it.
