Step‑by‑Step Instructions

  • Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking dish with butter or cooking spray.
  • Cut the buttery croissants into quarters and arrange them evenly at the bottom of the prepared baking dish.
  • Sprinkle the diced ham generously over the croissant pieces, followed by an even layer of shredded Swiss cheese.
  • In a medium bowl, whisk together the eggs, milk, dried thyme, garlic powder, salt, and pepper until thoroughly combined.
  • Pour the egg mixture evenly over the croissant and ham layers, pressing down to absorb the custard.
  • Sprinkle the grated Parmesan cheese over the casserole's top.
  • Cover the baking dish with foil and bake for 30 minutes.
  • Remove the foil and bake for an additional 15-20 minutes, or until the top is golden brown.
  • Let the casserole cool for about 5 minutes and garnish with freshly chopped chives.
