How to Make Ham and Cheese Croissant Breakfast Casserole

  1. Preheat your oven to 350°F (175°C). This ensures even cooking so the casserole turns out perfectly fluffy and golden.

  2. Prepare your baking dish by lightly coating a 9×6 or 9×11 deep baking dish with cooking spray. This helps to prevent sticking, ensuring easy serving later on.

  3. Layer the croissants by tearing them into halves and placing them in the prepared dish, creating a fluffy foundation for your casserole.

  4. Chop the ham into thirds and distribute it evenly around the croissant layers. This way, every bite will have a delicious, smoky flavor.

  5. Sprinkle shredded cheese generously over the croissants and ham. This melty layer will bind all the ingredients together beautifully.

  6. Whisk together eggs, half and half, Dijon mustard, and salt in a separate bowl. Pour this creamy mixture evenly over the layered ingredients in the dish.

  7. Cover the dish with foil and chill it in the refrigerator for 30 minutes to overnight. This soaking time allows the croissants to absorb the custard mixture for better flavor.

  8. Bake the casserole covered for 20 minutes, then remove the foil and continue baking for an additional 10-15 minutes until it’s bubbly and golden brown on top.

  9. Rest for 5 minutes before serving. Dust with powdered sugar for a sweet finish, and enjoy this delightful brunch dish!

Optional: Serve with a dollop of your favorite jam for an extra touch of sweetness.
