Ham and Cheese Croissant Breakfast Casserole
Flakey, Buttery Croissants, diced ham and gooey cheese are the base for this easy make-ahead breakfast casserole. Make it the night before and bake it fresh in the morning for an easy start to your day.
Equipment
- 1 9x13 cake pan
Ingredients
- 6 croissants, torn into bite sized pieces Day old works best
- 5-6 large eggs If you want it more custardy then add the 6th egg, otherwise use 5
- 1½ cup whole milk (or heavy cream and milk)
- 1 cup grated cheese of choice I like swiss and cheddar
- 1 cup thinly sliced ham, cut into about 1" pieces I use deli ham, but any ham will work
- 1 tsp dry mustard powder
- ½ tsp kosher salt
- ¼ tsp freshly ground black pepper
- powdered sugar (optional)
Instructions
- Lightly spray a 9x13" baking pan with cooking spray (or butter generously)
- Tear the croissants into about 1" pieces and place them into the baking pan in an even layer, then sprinkle the ham pieces over the top, then cover with the grated cheese.
- In a separate bowl, combine the 5-6 large eggs, 1½ cup whole milk (or heavy cream and milk), 1 tsp dry mustard powder, ½ tsp kosher salt and ¼ tsp freshly ground black pepper. Whisk well to combine then pour the mixture evenly over the croissant and ham and cheese base. Cover and refrigerate overnight or at least 4 hours.
- In the morning, preheat your oven to 350℉
- remove the casserole from the refrigerator and cover with foil, bake covered for 30 minutes then uncover and bake for a further 10 minutes until it is golden brown. Remove from oven and let rest for 5 minutes then sprinkle with powdered sugar if desired. Cut into 8 servings and enjoy.
Notes
This is a family favorite, and it's so easy to make. Even those who don't like eggs will enjoy this breakfast casserole.
If you want a vegetarian option you can omit the ham and cheese and add frozen blueberries and some maple syrup for a sweet version.
