Ingredients
  

Main Ingredients
  • 6 croissants Croissants, preferably day-old Slightly stale croissants work best
  • 1 cup Ham, sliced or chopped Any ham can be used
  • 2 cups Swiss cheese, shredded or torn Other cheeses can be substituted
  • 4 large Eggs Large eggs for best results
  • 1 cup Milk or half and half Half and half adds richness
  • 2 tablespoons Dijon mustard Optional but recommended for added flavor
  • 1 teaspoon Salt Season to taste, especially if ham is salty
  • 1 teaspoon Pepper Black pepper for seasoning
  • 1 pinch Garlic powder Optional flavor enhancer
  • 2 tablespoons Butter For greasing the baking dish

Method
 

Preparation
  1. Preheat the oven to 350°F (175°C).
  2. Grease a baking dish with butter.
  3. Tear the croissants into bite-sized pieces and place them in the baking dish.
  4. Sprinkle the chopped ham and shredded Swiss cheese over the croissant pieces.
  5. In a bowl, whisk together the eggs, milk or half and half, Dijon mustard, salt, pepper, and garlic powder.
  6. Pour the egg mixture evenly over the croissant and ham mixture, pressing down gently to ensure everything is soaked.
  7. Cover the dish with foil and let it rest in the refrigerator for at least 30 minutes or overnight for best results.
Baking
  1. Remove the dish from the refrigerator about 15-20 minutes before baking.
  2. Bake in the preheated oven for 45 minutes, removing the foil for the last 10-15 minutes until the top is golden and the center is set.
  3. Let it cool for 10 minutes before slicing and serving.

Notes

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven for best results. This dish is great for make-ahead brunches, and for variations, feel free to swap cheeses or add vegetables like spinach or onions.
