Start your morning right with this Ham and Cheese Croissant Casserole. Buttery croissants, cheddar and fontina cheeses, tender mushrooms, sweet onions, and savory ham come together in a creamy custard baked to perfection.

This Is One Of My Favorite Breakfast Casseroles Because It’s…
- Packed with Flavor: A rich custard pairs perfectly with melty cheeses, smoky ham, and sautéed vegetables.
- Versatile: Great for breakfast, brunch, or even dinner.
- Make-Ahead Friendly: Prep it the night before and bake fresh in the morning.
- Crowd-Pleasing: Ideal for holiday entertaining or feeding a hungry family.
Some Tips For Making This Richly Satisfying Breakfast Casserole
- Custard absorption: Let the croissants soak in the custard for at least 15-20 minutes to ensure the casserole is moist and flavorful.
- Check for doneness: When done, the casserole should be puffed and have a slight jiggle in the center. It will continue to set as it cools.
- Grease the pan: Spray with cooking spray or brush with butter or oil to prevent sticking.
- Cooling time: Let the casserole rest for 10 minutes before serving for the best texture.
The Ingredients That Make This Casserole A Standout
are things you likely already have in your fridge.
- Large Eggs, Heavy Cream, and Whole Milk make up the custard base.
- Onions, Mushrooms, and Garlic sautéed in Olive Oil, plus a bit of Thyme stirred in when mixing, add lots of flavor.

Making This Ham And Cheese Croissant Casserole Couldn’t Be Easier
