Description

Perfecting Ham Cheese Croissant takes zero fancy skills – just grab some flaky pastry, pile on salty ham slices, and sprinkle sharp cheese before a quick oven bake that brings delicious European cafe charm right to your kitchen counter.


Ingredients

Scale

Protein & Base:

  • 6 large eggs
  • 1 ½ cups diced ham
  • 4 large croissants

Dairy & Cheese:

  • 1 ½ cups shredded cheddar cheese
  • ½ cup heavy cream
  • 1 ½ cups milk

Seasonings & Optional Add-Ins:

  • 1 teaspoon Dijon mustard
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • ½ cup diced bell peppers
  • ¼ cup chopped green onions
  • ½ teaspoon red pepper flakes

Instructions

  1. Rip 4 large croissants into bite-sized chunks, spreading them across a greased 9×13-inch baking dish to create an even base for your breakfast casserole.
  2. Allow fresh croissants to air-dry for several hours, helping them better absorb the upcoming egg mixture.
  3. Scatter 1½ cups diced ham across the croissant pieces, ensuring uniform coverage of your base layer.
  4. Generously distribute 1½ cups shredded cheddar cheese over the ham, creating a rich, melty topping.
  5. Whisk 6 large eggs, 1½ cups whole milk, ½ cup heavy cream, 1 teaspoon Dijon mustard, ½ teaspoon garlic powder, ½ teaspoon onion powder, ½ teaspoon salt, and ¼ teaspoon black pepper in a large bowl until completely blended.
  6. Pour the egg mixture slowly over the croissants, ensuring every piece gets thoroughly coated with the liquid.
  7. Gently press down on the croissants to help them absorb the egg mixture more effectively.
  8. Refrigerate the casserole, covered with plastic wrap, for a minimum of 30 minutes to enhance flavor absorption.
  9. Heat your oven to 375°F (190°C), preparing for the baking process.
  10. Remove the casserole from the refrigerator and let it rest at room temperature for 10 minutes before baking.
  11. Cover the dish with aluminum foil and bake for 30 minutes, then uncover and continue baking for an additional 10-15 minutes until the top turns golden brown and the center sets completely.
  12. Allow the casserole to cool for 5 minutes after removing from the oven, which helps it maintain structural integrity when serving.
  13. Optional: Sprinkle chopped green onions or fresh parsley on top for added color and fresh flavor before serving warm.

Notes

  • Selecting slightly stale croissants helps them soak up the egg mixture without becoming soggy, creating a perfect texture.
  • Letting the casserole rest in the refrigerator allows the flavors to meld and the croissants to fully absorb the liquid, making each bite more delicious.
  • For a lighter version, substitute half-and-half for heavy cream and use lean ham to reduce overall calories.
  • Experiment with different cheese varieties like gruyère or sharp cheddar to customize the flavor profile and make the dish your own.
