Smoky Ham & Cheese Croissant Casserole

20 minutes prep + 35 minutes cook
6 servings
Easy and delicious breakfast casserole made with croissants, smoked ham, melty cheese, and eggs. The best savory French toast recipe!

Ingredients 

  • 12 large eggs
  • 1 cup half-and-half, or cream
  • 2 to 3 tsp sea salt
  • ground black pepper, to taste
  • 1 tsp paprika
  • 12 oz smoked ham, finely diced
  • 7 oz smoked cheese, (I use Smoked Beechers)
  • 3 tbsp finely chopped chives
  • 6 to 7 large butter croissants, (For size reference, I use Costco croissants)
  • 2 tbsp finely chopped chives, for garnish

Instructions

Preparing the Casserole:

  • Preheat the oven to 425°F. Butter the bottom and sides of a 9x13-inch (or similar) casserole dish.
  • Dice the smoked ham into small, pea-sized pieces. Grate the cheese into a small bowl.
  • In a large mixing bowl, combine the eggs and half-and-half (or cream). Season with salt, pepper, and paprika, then whisk for a few minutes until the eggs are well-beaten.
  • Add the diced ham next, along with the grated cheese and finely chopped chives. Stir everything together.
  • Use a bread knife to gently cut the croissants into 1 ½-inch pieces. Drop the croissant pieces into the buttered casserole dish.
  • Pour the prepared egg, ham, and cheese mixture over the croissants. Use a spoon or spatula to toss everything together, allowing the croissants to soak up the egg custard. There should be no dry pieces of bread.
  • Arrange the croissants in an even layer. Sprinkle additional chopped chives over the casserole, as garnish.

Baking Instructions:

  • Bake the ham and cheese casserole at 425°F for 34 to 38 minutes. At the 15-minute baking mark, lay a sheet of foil over the casserole to prevent the croissants from browning too much.
  • Bake until the egg custard is completely set. There should be no liquid egg at the top.
  • Make-ahead instructions: follow the instructions as written, then cover and refrigerate the casserole before baking. Bake as usual at 425°F.
  • To serve this delicious ham and cheese casserole, use a sharp serrated knife to cut the dish into individual servings. Enjoy the casserole warm for the best tasting results. Try pairing the casserole with salsa or hot sauce for additional flavor.
