Ingredients
  

  • Non-stick cooking spray
  • 6 large eggs
  • 1 1/2 cups whole milk 360 ml
  • 1/2 cup buttermilk 120 ml
  • 1/2 teaspoon granulated garlic
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • 6 bakery croissants cut into 2-inch pieces, 12 oz / 340 g
  • 2 cups chopped cooked ham 280 g
  • 1/2 cup shredded provolone cheese 50 g
  • 1/2 cup shredded sharp cheddar cheese 50 g

Instructions
 

  • Coat an 8x8-inch baking dish with non-stick cooking spray and set it aside.
  • Whisk the eggs, whole milk, buttermilk, granulated garlic, kosher salt, and black pepper together in a medium bowl.
  • Place the chopped croissants and ham in a large bowl. Pour the egg mixture over the top and stir gently until the bread is evenly coated.
  • Transfer the mixture to the prepared baking dish. Cover tightly with plastic wrap or foil and refrigerate for 8 hours or overnight.
  • Preheat the oven to 350°F (175°C) when you are ready to bake.
  • Uncover the casserole and sprinkle the shredded provolone and cheddar cheese evenly over the top.
  • Bake uncovered for 40 to 45 minutes. The casserole is done when the eggs are fully set and the center reaches a safe internal temperature of 160°F (71°C).
  • Remove from the oven and let the casserole cool for 10 minutes before serving.

Notes

Check the center of the casserole with a food thermometer to ensure the eggs reach a safe internal temperature of 160°F (71°C).
If the top of the casserole starts browning too quickly during baking, tent a piece of aluminum foil loosely over the dish.
You can substitute different cheeses like Swiss or Gruyere depending on what you have in your refrigerator.
