Scale
Main Ingredients
- 5 large croissants, preferably day-old, cut into bite-sized pieces
- 6 large eggs
- 1 ¾ cups whole milk
- ½ cup heavy cream
- 1 cup shredded cheddar cheese
- ½ cup shredded mozzarella cheese
- 1 cup cooked breakfast sausage or bacon, crumbled
- ½ cup diced bell peppers
- ¼ cup chopped green onions
- ½ tsp garlic powder
- ½ tsp salt
- ¼ tsp black pepper
- Butter or nonstick spray for greasing
Instructions
- Prepare the Baking Dish: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with butter or nonstick spray to prevent sticking.
- Layer Croissants: Evenly distribute the bite-sized croissant pieces in the bottom of the prepared baking dish, forming a base for the casserole.
- Mix Wet Ingredients: In a large bowl, whisk together the eggs, whole milk, heavy cream, garlic powder, salt, and black pepper until the mixture is smooth and well combined.
- Add Flavorings: Stir the cooked breakfast sausage or bacon, diced bell peppers, chopped green onions, shredded cheddar cheese, and shredded mozzarella cheese into the egg mixture, evenly blending all components.
- Combine and Soak: Pour the egg and sausage mixture evenly over the croissant pieces in the baking dish. Gently press the croissants down to ensure they soak up the liquid and flavors.
- Rest the Casserole: Let the assembled casserole sit for 10–15 minutes at room temperature to allow the croissants to absorb the mixture. For a make-ahead option, cover and refrigerate overnight.
- Bake: Place the casserole in the preheated oven and bake for 35–40 minutes, or until the top is golden brown and the center is set and firm to the touch.
- Rest and Serve: Remove from the oven and let the casserole rest for 5–10 minutes before slicing. This helps it set further and makes serving easier.
Notes
- Customize your casserole by adding spinach, mushrooms, or using different cheeses to suit your taste.
- If baking the casserole from chilled after refrigeration, add an additional 5–10 minutes to the baking time to ensure it cooks through.
- This dish can be made vegetarian by omitting the sausage or bacon.
- Use day-old croissants for best texture as they absorb the custard mixture better.
