Preparing Irresistible Overnight Croissant Breakfast Casserole
Creating an irresistible overnight croissant breakfast casserole is not just about food; it’s about crafting a delightful brunch experience that’s perfect for lazy weekends or special gatherings. Follow these step-by-step instructions for a dish that blends buttery croissants with savory fillings, all topped with a creamy egg mixture for a truly indulgent breakfast.
Prepare the Baking Dish
Before diving into the delicious layers of your casserole, it’s essential to prep your baking dish. Choose a 9×13-inch dish for this recipe—it’s the perfect size for serving a crowd, but also manageable for smaller families.
- Grease the dish: Lightly coat your baking dish with non-stick cooking spray or butter to prevent the casserole from sticking. This ensures easy cleanup and that each serving comes out beautifully.
- Preheat the oven: While you don’t need the oven just yet, preheating it to 350°F will save you some time later.
Layer the Croissants, Turkey Bacon, and Cheese
Now for the fun part! Layering is what makes this breakfast casserole visually appealing and flavorful.
-
Croissants: Start with around 6–8 croissants, depending on their size. Tear or cut them into pieces and spread them evenly across the greased baking dish. The buttery richness of croissants will create a soft, flaky base that you won’t want to miss.
-
Turkey Bacon: Next, add cooked turkey bacon for that savory element. You can chop it into bite-sized pieces to ensure it distributes nicely throughout the casserole. This ingredient plays a crucial role—providing protein while complementing the croissants’ texture perfectly.

-
Cheese: Don’t hold back on the cheese! Sprinkle a generous layer of shredded mozzarella or cheddar cheese over the turkey bacon. Cheese not only adds creaminess but also creates a golden, bubbly top that makes this casserole totally Instagram-worthy.
Create the Creamy Egg Mixture
The magic of this casserole lies in the creamy egg mixture. It binds all the ingredients together and adds that delightful custardy texture.
- Ingredients for the egg mixture: In a large bowl, whisk together the following:
- 8 large eggs
- 2 cups of whole milk or a milk alternative
- 1 teaspoon of Dijon mustard
- Salt and pepper to taste for seasoning
Blend these together until smooth, ensuring everything is well combined. The addition of Dijon mustard gives a subtle zing that elevates the flavors, bringing an extra layer of sophistication to your dish.
Combine and Let It Soak Overnight
Pour the egg mixture evenly over the layered croissants, turkey bacon, and cheese.
- Soaking time: Gently press down on the layers with a spatula to help the croissants absorb the egg mixture. Cover the baking dish with plastic wrap and place it in the refrigerator overnight. Allowing the casserole to soak overnight not only integrates the flavors but also simplifies your morning routine.
Bake to Golden Perfection in the Morning
When morning rolls around, it’s time for the grand reveal! Remove the casserole from the fridge and let it sit at room temperature for about 20 minutes.
- Baking instructions: Preheat your oven if you haven’t already to 350°F. Then, uncover the dish and bake for 35-45 minutes, or until the top is golden brown and a toothpick inserted comes out clean. The aroma that fills your kitchen while it’s baking will make it hard to resist!
Serve your irresistible overnight croissant breakfast casserole warm, and watch as your friends and family indulge in every delicious bite. This dish is not only easy to prepare but also creates lasting memories over the breakfast table. For an extra touch, serve with fresh fruit or a side of your favorite jam. Happy cooking!

FAQs about Irresistible Overnight Croissant Breakfast Casserole
Can I use fresh croissants instead of day-old?
Absolutely, fresh croissants can work in this delightful casserole! However, day-old croissants are preferred because they’re a bit dryer, allowing them to absorb the rich custard mixture without becoming too soggy. If you do opt for fresh croissants, consider letting them sit out for a few hours or even lightly toasting them before assembling your casserole. This can help achieve that perfect balance of buttery softness and slight crispiness, enhancing the overall texture.
How can I make this dish lighter?
If you’re looking to create a lighter version of this irresistible overnight croissant breakfast casserole, here are a few tweaks:
- Use egg substitutes: Consider substituting some eggs with egg whites. This can drastically cut down on cholesterol while maintaining the fluffiness.
- Switch dairy: Opt for low-fat milk or a plant-based alternative. Unsweetened almond milk, for instance, can still provide creaminess with fewer calories.
- Swap proteins: Replace heavier meats with leaner options like turkey bacon or chicken ham. Both options provide flavor without adding too much fat.
What’s the best way to store leftovers?
To enjoy your irresistible overnight croissant breakfast casserole later, simply cover it with plastic wrap or transfer it to an airtight container. Leftovers can be stored in the refrigerator for up to three days. For those who want to enjoy it warm, just pop it in the oven at 350°F for about 15-20 minutes, or until heated through. If you’re planning to save some for longer, consider freezing portions. Just remember to slice it before freezing for easy reheating!
