I love making breakfast casseroles because they are so easy and quick to make. This one might be my favorite with buttery croissants, smokey ham and lots of gooey cheese surrounded by a rich and creamy custard. It’s so easy to make and delicious as breakfast or for brunch. This is the perfect holiday morning breakfast…and will be a favorite of all your guests!
Croissant Breakfast Casserole
6-8 medium-sized croissants
4 large eggs
1 cup half and half
1 tablespoon Dijon mustard (optional)
1 teaspoon salt
1 teaspoon parsley
1 teaspoon of chives
8 ounces deli or leftover ham (about 6 thin slices)
6 ounces shredded white cheddar, Swiss or Gruyere cheese
Lightly coat a 9×6 deep baking dish with cooking spray. You can also use a 9×11. Tear croissants into 2-3 inch pieces and place in your prepared pan.
Cut ham into bite size pieces and nestle around the croissants.
Sprinkle on shredded cheese.
In a small bowl, whisk together eggs, half and half, Dijon mustard (if using), parsley, chives and salt. Pour over croissants.
Cover with foil and chill in the refrigerator for at least 30 minutes. You can make it the night before and store it in the refrigerator overnight if you want a quick morning breakfast.
Heat oven to 350 degrees. Place covered breakfast casserole in the oven and bake for 20 minutes.
Remove the foil and continue to bake for another 10 to 15 minutes until hot and bubbly with a golden top.
Remove casserole from the oven and let rest for 5 minutes and then cut into squares and serve.
