3) Ingredients for Ham and Cheese Croissant Breakfast Casserole
Croissants: Six large croissants torn into chunks. They create a buttery base that holds flavor and texture.
Ham: About one and a half cups of cooked ham diced small. It adds a savory depth that balances the cheese.
Cheddar Cheese: One and a half cups shredded. Cheddar melts rich and sharp which gives the casserole its body.
Mozzarella Cheese: Half a cup shredded. It stretches beautifully and softens the bite of cheddar.
Eggs: Six large eggs whisked with milk. They bind the ingredients and create a custard texture.
Milk: Two cups of whole milk. It makes the custard tender and full.
Salt and Pepper: Just enough to season the dish without overwhelming the croissants.
Garlic Powder and Onion Powder: A quarter teaspoon each. They add depth without needing extra chopping.
Butter: A swipe in the pan to keep the casserole from sticking and add a bit of flavor at the edges.

4) How to Make Ham and Cheese Croissant Breakfast Casserole
Step 1. Preheat the oven to 350°F. Butter a baking dish so the croissants don’t cling to the sides.
Step 2. Layer half the croissant pieces in the dish. Scatter half the ham and half the cheese over the top. Repeat so every bite has balance.
Step 3. In a bowl whisk eggs, milk, salt, pepper, garlic powder, and onion powder until smooth. It should look golden and creamy.
Step 4. Pour the custard over the layered croissants. Use a spatula to gently press the bread down so it soaks.
Step 5. Slide the dish into the oven. Bake for about 40 to 45 minutes until the center sets and the top turns golden.
Step 6. Let it rest for 5 minutes before cutting. That short wait makes slicing neat and keeps the texture just right.

5) Tips for Making Ham and Cheese Croissant Breakfast Casserole
Use day old croissants if you can. They soak up custard better and hold their structure. Fresh croissants work but may feel softer after baking.
Mix cheeses for more flavor. Cheddar gives bite while mozzarella adds stretch. Swap in Swiss if you like a sharper finish.
Consider extras like broccoli or spinach. They give a broccoli and cheese casserole recipe touch that balances the richness of ham and cheese.
Don’t skip seasoning. Even small pinches of salt and pepper shape the final flavor. A breakfast casserole benefits from careful seasoning every step of the way.
6) Making Ham and Cheese Croissant Breakfast Casserole Ahead of Time
I like to build this casserole the night before. I layer the croissants, ham, and cheese, then pour the custard over the top. Cover it and leave it in the fridge overnight. In the morning, I just bake it while the coffee brews.
This trick works well if you’ve got a busy morning or guests. It’s almost like setting a Crock Pot ham recipe and forgetting it, but the oven does the job instead. The flavors come together while it chills, making it even better.
When baked straight from the fridge, it may need an extra five minutes in the oven. Just check that the center has set before pulling it out.
7) Storing Leftover Ham and Cheese Croissant Breakfast Casserole
Leftovers keep well. I wrap slices in foil and keep them in the fridge. They last up to three days. The croissants stay soft, the ham holds flavor, and the cheese remains creamy.
For reheating, the oven is best. Warm slices at 325°F for about 10 minutes. It keeps texture better than the microwave though the microwave works in a pinch.
If you freeze portions, wrap them tight in plastic and foil. They’ll keep for up to two months. Thaw overnight in the fridge before baking again.
