Ingredients
  

Main Ingredients
  • 6 pieces croissants (preferably day-old)
  • 6 large eggs
  • 1 cup milk (dairy or plant-based)
  • 1 cup shredded cheese (cheddar, Swiss, or your favorite)
  • 1 cup diced vegetables (bell peppers, spinach, or mushrooms)
  • ½ cup diced cooked ham or crumbled breakfast sausage (optional)
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • 1 teaspoon dried herbs (thyme, basil, or Italian seasoning)

Method
 

Preparation
  1. Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish.
  2. Tear the croissants into bite-sized pieces and scatter them evenly across the greased dish.
  3. In a mixing bowl, whisk together the eggs, milk, salt, pepper, and dried herbs until smooth.
  4. Pour the egg mixture over the croissants, ensuring all pieces are coated.
  5. Add the cheese, diced vegetables, and any optional protein on top, mixing gently with a spatula.
  6. Let the mixture rest for about 20 minutes to allow the croissants to absorb the custard.
  7. Bake in the preheated oven for approximately 30-35 minutes, until golden and puffy.
