Ham and Cheese Breakfast Casserole Ingredients

The base of this casserole combines cubed up large croissants with chopped Black Forest deli ham and shredded Swiss cheese. Once the foundation is in the casserole dish, it’s covered in an egg mixture that consists of large eggs and half and half.

The egg mixture is first seasoned with salt, mustard powder, garlic powder, white ground pepper, and maple syrup before being poured over the ham, croissants, and cheese.

Before enjoying the breakfast casserole, we love dusting ours with powdered sugar, raspberry jam, and maple syrup. YUM!

How To Make A Ham And Cheese Breakfast Casserole With Croissants

1. Cut large croissants up into cubes and add them to a large bowl.
2. Chop Black Forest deli ham up into pieces and add them to the bowl of croissants.
3. Add shredded Swiss cheese to the bowl with ham and croissants, then toss the mixture to combine.
4. Spread the mixture into your baking pan and set it aside.
5. Beat large eggs in a mixing bowl. Then mix in half and half, 100% pure maple syrup, salt, mustard powder, garlic powder, and white ground pepper.
6. Pour the egg mixture over the top of the croissant mixture in the baking dish as evenly as you can. Then drizzle additional maple syrup over the top.
7. Cover the casserole with aluminum foil and allow it to soak.
8. Preheat the oven.
9. Bake the Ham and Cheese Breakfast Casserole covered for the first half of baking. Next, remove the aluminum foil, rotate the pan, and finish baking until the top is golden brown with the egg fully cooked.
10. Dust with powdered sugar and serve with raspberry jam and/or additional maple syrup. Enjoy!

• Dried Out Croissants – For best results, let the croissants sit out unsealed for at least 8 hours before using. This will dry them out, which will then allow them to absorb the egg mixture better. You can leave them out overnight if you plan to make the casserole in the morning!
• Soak Time – Be sure to let the casserole soak for a minimum of 20 minutes (or overnight!) while the oven preheats. Don’t just throw it right in the oven without giving it time to soak!
• Ham – We found that Black Forest Deli ham was the best to use in this casserole. We tried other varieties of ham and even ham steak but just didn’t like the casserole as much as when we used Black Forest.
• Cheese – We tried making the casserole with deli-sliced Swiss cheese, which worked okay, but ultimately found that shredded Swiss was easier to mix and distribute evenly throughout the dish.

How To Store and Reheat Croissant Breakfast Casserole

Once the casserole has been baked, it’s best to enjoy it fresh for peak taste and texture. However, if you’d like you can store leftovers in an airtight container in the fridge for 2 to 3 days.

I recommend reheating the breakfast casserole in the oven for the best results.

How To Make Croissant Casserole Ahead Of Time

To make this breakfast casserole ahead of time follow the instructions on the recipe card through step 7. Then slide the baking dish into the fridge once it’s tightly covered with aluminum foil.

In the morning, preheat the oven and continue with the recipe instructions. Keep in mind that overnight prep yields an eggier texture in the casserole. However, it’s still absolutely delicious!
