Gather These Items

To create this delectable dish, you’ll need the following ingredients:

6 large croissants, torn into pieces
8 large eggs
2 cups milk
1 cup shredded cheese (cheddar or your choice)
1/2 cup cooked and crumbled bacon or sausage
1/4 cup chopped green onions
1 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon Dijon mustard (optional)

Feel free to substitute the meat with vegetables for a lighter option or choose your favorite cheese to personalize the flavor!

Directions to Follow

In a large bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and Dijon mustard until smooth.
Layer the torn croissant pieces evenly in a greased baking dish.
Sprinkle the crumbled bacon or sausage, cheese, and green onions over the croissant layer.
Gently pour the egg mixture evenly over the top, ensuring all croissant pieces are well-coated.
Cover the dish with plastic wrap or foil and refrigerate overnight (or for at least 2 hours).
Preheat your oven to 350°F (175°C).
Remove the casserole from the fridge, uncover it, and bake for 30-40 minutes, or until the top is golden brown and the casserole is set.
Allow it to cool for a few minutes before serving.

Best Ways to Enjoy It

To elevate your breakfast experience, consider serving this casserole with a side of mixed fruit or a simple green salad for balance. Drizzle with a touch of hot sauce or a dollop of sour cream for added flavor. Pair it with freshly brewed coffee or a light fruit smoothie to round out the meal.

How to Store

If you have leftovers (which is uncommon, but hey, it happens!), store them in an airtight container in the fridge for up to 3 days. Reheat individual portions in the microwave or pop it back in the oven at 350°F until warmed through. For longer storage, you can freeze portions for up to 2 months—just ensure you wrap them tightly to prevent freezer burn.

Helpful Cooking Tips

For extra creaminess, consider adding a splash of heavy cream to the egg mixture.
Allow the casserole to cool slightly before cutting to help it hold its shape better.
Feel free to mix in or top with additional herbs, like parsley or thyme, to enhance the flavor.
Use day-old croissants for a better texture, as they will absorb the egg mixture beautifully.

Recipe Variations

Get creative with this casserole! Swap out the bacon or sausage for sautéed vegetables like spinach or bell peppers for a delicious vegetarian twist. Experiment with different types of cheese, such as feta or pepper jack, to give it a unique spin. You could even add seasonal ingredients to make it festive, like pumpkin puree in the fall.
