How to Make Overnight Croissant Breakfast Casserole
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). This ensures your casserole bakes evenly. While the oven warms up, grab a 9×13-inch baking dish and grease it with cooking spray or butter. This step is crucial; it prevents sticking and makes serving a breeze. Trust me, no one wants to wrestle with a stuck casserole! With the dish ready, you’re one step closer to breakfast bliss.
Step 2: Whisk the Egg Mixture
In a large mixing bowl, crack open those eight eggs. Add in the whole milk, Dijon mustard, garlic powder, salt, black pepper, and nutmeg. Whisk everything together until it’s well combined. You want a smooth, creamy mixture that will soak into the croissants. This egg mixture is the heart of your Overnight Croissant Breakfast Casserole, bringing all the flavors together. So, whisk with enthusiasm!
Step 3: Layer the Croissants
Now, it’s time to layer those flaky croissants. Tear them into bite-sized pieces and spread them evenly across the bottom of your greased baking dish. Make sure to cover the entire surface; this will create a delicious base for your casserole. The croissants will soak up all the egg mixture, turning into a delightful, custardy texture. It’s like a warm hug for your taste buds!
Step 4: Add Fillings
Next, sprinkle the diced cooked ham, chopped spinach, and shredded cheddar cheese over the croissant pieces. This is where the magic happens! The ham adds heartiness, the spinach brings freshness, and the cheese melts into gooey perfection. Feel free to get creative here—add more veggies or switch up the cheese for a unique flavor twist. Each layer adds depth to your Overnight Croissant Breakfast Casserole.
Step 5: Pour the Egg Mixture
Carefully pour the egg mixture over the layered croissants and fillings. Make sure to cover everything evenly, ensuring that each piece of croissant is soaked in that delicious custard. This soaking is key; it allows the flavors to meld together beautifully. If you notice any dry spots, gently press down on the croissants to help them absorb the mixture. You want every bite to be bursting with flavor!
Step 6: Refrigerate
Cover the dish with plastic wrap and pop it in the refrigerator. Let it chill for at least four hours, or ideally overnight. This resting period allows the croissants to soak up all that eggy goodness, resulting in a richer flavor and texture. It’s the perfect make-ahead option for busy mornings. Just think, you’ll wake up to a ready-to-bake casserole waiting for you!
Step 7: Bake
When you’re ready to bake, take the casserole out of the fridge and let it sit at room temperature for about 15 minutes. This helps it bake evenly. Then, place it in your preheated oven and bake for 35-40 minutes. You’re looking for a golden-brown top and a set center. The aroma will fill your kitchen, making it hard to resist. Once it’s done, let it cool for a few minutes before slicing and serving. Enjoy the deliciousness!
Tips for Success
Use day-old croissants for better absorption of the egg mixture.
Don’t skip the refrigeration step; it’s crucial for flavor development.
Experiment with different cheeses for a unique twist.
For a spicier kick, add diced jalapeños or red pepper flakes.
Let the casserole cool slightly before slicing for cleaner pieces.
Equipment Needed
