A quick and easy croissant bake combining day-old croissants, savory ham, and melted Gruyere cheese for a cozy and indulgent brunch dish.

Ingredients

Scale
  • 6 large day-old croissants, roughly torn into bite-sized pieces
  • 8 ounces diced cooked ham
  • 1 ½ cups shredded Gruyere cheese
  • 5 large eggs, room temperature
  • 2 cups whole milk
  • 1 tablespoon Dijon mustard
  • 1 teaspoon fresh thyme leaves, finely chopped (optional)
  • Salt and pepper to taste
  • 1 tablespoon butter, for greasing the baking dish

Instructions

  1. Preheat your oven to 350°F (175°C).
  2. Butter the bottom and sides of a 9×13-inch baking dish to prevent sticking.
  3. Tear croissants into roughly 2-inch bite-sized pieces and place evenly in the prepared dish.
  4. Scatter diced ham evenly over the croissants, then sprinkle shredded Gruyere cheese on top.
  5. In a large bowl, whisk together eggs, whole milk, Dijon mustard, chopped thyme, salt, and pepper until smooth.
  6. Pour the custard mixture evenly over the croissant, ham, and cheese layers, pressing down lightly to help soak the custard.
  7. Let the dish rest for 15 minutes to allow the croissants to absorb the custard.
  8. Bake uncovered for 35-40 minutes until the top is golden brown and set, and a knife inserted in the center comes out clean. If the top browns too quickly, tent loosely with foil halfway through baking.
  9. Let cool for 5-10 minutes before cutting and serving.

Notes

Use day-old croissants for best texture; let the custard soak for 15 minutes before baking. If top browns too fast, cover with foil halfway through baking. Room temperature eggs and milk help create a smooth custard. For gluten-free, use gluten-free croissants; for dairy-free, substitute milk and cheese accordingly.
