Ingredients

Scale

Main Proteins:

  • 6 large eggs
  • 1.5 cups diced ham
  • 1.5 cups shredded cheddar cheese
  • 0.5 cup shredded Swiss or Gruyere cheese

Bread and Vegetables:

  • 4 large croissants, torn into chunks
  • 0.5 cup diced bell peppers
  • 0.5 cup sauteed mushrooms
  • 1 cup baby spinach, chopped

Seasonings and Liquids:

  • 1.5 cups whole milk
  • 0.5 cup heavy cream
  • 0.5 teaspoon salt
  • 0.5 teaspoon black pepper
  • 0.5 teaspoon garlic powder
  • 0.5 teaspoon onion powder
  • 0.5 teaspoon Dijon mustard
  • 1 tablespoon chopped fresh parsley

Instructions

  1. Shred 4 large croissants into rustic chunks that will soak up the rich custard mixture perfectly. Spread these pieces evenly across a generously buttered 9×13-inch baking dish.
  2. Dice 1 ½ cups of ham into bite-sized cubes, ensuring each piece is roughly the same size for consistent flavor distribution throughout the casserole.
  3. Sprinkle 1 ½ cups shredded cheddar cheese and ½ cup Swiss cheese over the croissant chunks, creating a delightful cheesy layer.
  4. Whisk 6 large eggs in a large mixing bowl until they become smooth and slightly frothy. Add 1 ½ cups whole milk and ½ cup heavy cream to create the custard base.
  5. Season the egg mixture with ½ teaspoon each of salt, black pepper, garlic powder, and onion powder. Stir in ½ teaspoon Dijon mustard for an extra layer of complexity.
  6. Gently pour the seasoned custard over the croissants and cheese, making sure every piece gets saturated. Use a spatula to press down lightly and help absorption.
  7. Add ½ cup diced bell peppers, ½ cup sauteed mushrooms, and 1 cup chopped baby spinach for extra texture and nutrition.
  8. Cover the dish with aluminum foil and refrigerate for at least 2 hours or overnight to let the flavors meld together.
  9. Preheat your oven to 350°F. Remove the casserole from the refrigerator and let it sit at room temperature for 15 minutes.
  10. Bake the casserole, covered with foil, for 30 minutes. Then remove the foil and continue baking for an additional 20-25 minutes until the top turns golden brown and the center is set.
  11. Sprinkle 1 tablespoon of chopped fresh parsley over the top for a bright, fresh garnish. Let the casserole rest for 10 minutes before serving.

Notes

  • Choose day-old croissants for better texture and less moisture in the casserole.
  • Cut or tear croissants into roughly equal-sized pieces to ensure even cooking and distribution.
  • Grease the baking dish generously to prevent sticking and make cleanup easier.
  • Let the casserole sit for 10-15 minutes before baking to help the croissants absorb the egg mixture completely.
