Ingredients

The key to this dish lies in selecting the right ingredients, especially the croissants. I recommend using buttery, flaky croissants — preferably a day or two old — because they soak up the custard beautifully without turning mushy. For the cheese, I like a sharp cheddar that melts well and gives a nice tang, but Swiss or Gruyère work wonderfully too, adding depth and a touch of nuttiness. And of course, quality ham is essential; I use smoked deli ham for that extra flavor boost.

  • 6 large day-old croissants, torn into bite-sized pieces
  • 2 cups diced smoked ham
  • 2 cups shredded sharp cheddar cheese (or Swiss/Gruyère)
  • 4 large eggs
  • 2 cups whole milk
  • 1 cup heavy cream
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • 1/4 teaspoon garlic powder (optional)
  • Fresh chives or parsley for garnish (optional)

Instructions

  1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with butter or non-stick spray.
  2. Tear the croissants into bite-sized pieces and spread half of them evenly in the prepared dish.
  3. Layer half of the diced ham and shredded cheese over the croissants, then repeat the layers with the remaining croissants, ham, and cheese.
  4. In a large bowl, whisk together the eggs, whole milk, heavy cream, Dijon mustard, salt, pepper, and garlic powder until fully combined.
  5. Pour the custard mixture evenly over the layered croissants, pressing down gently to help the bread absorb the liquid.
  6. Cover the casserole with plastic wrap and refrigerate for at least 1 hour, or overnight for best results. This step allows the flavors to meld and the croissants to soak thoroughly.
  7. Remove the plastic wrap and bake uncovered for 45-50 minutes, or until the top is golden brown and the custard is set (a knife inserted should come out clean).
  8. Let the casserole rest for 10 minutes before serving. Garnish with fresh chives or parsley if desired.
