Ingredients
Scale
Butter Mixture
- 1/3 cup unsalted butter (at room temperature)
- 2 tablespoons Dijon mustard
- 2 green onions (thinly sliced)
- 1 tablespoon honey
- ½ tsp sea salt
- ¼ tsp black pepper
Sandwich Components
- 12 croissants (halved horizontally)
- 1 pound thinly sliced smoked deli ham
- 12 slices Swiss cheese (diagonally sliced)
Topping
- 1 large egg white
- 2 teaspoons poppy seeds
Instructions
- Preheat Oven: Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius). Lightly oil a 9 x 13-inch baking dish or coat it with nonstick spray to prevent sticking.
- Prepare Butter Mixture: In a small bowl, combine the softened unsalted butter, Dijon mustard, thinly sliced green onions, and honey. Season the mixture with sea salt and black pepper to taste, stirring until well blended.
- Assemble Croissants: Spread the prepared butter mixture on both the cut sides of each croissant half. Layer the bottom halves with smoked deli ham and Swiss cheese slices, then top with the other half to form 12 sandwiches.
- Arrange in Baking Dish: Place the assembled croissant sandwiches in a single layer inside the prepared baking dish, ensuring they have enough space for even baking.
- Prepare Egg Wash and Toppings: In a small bowl, whisk together the egg white and 1 tablespoon of water to create an egg wash. Brush the tops of each croissant sandwich with the egg wash, then sprinkle with poppy seeds evenly.
- Bake: Bake in the preheated oven until the croissants are golden brown and toasted, approximately 15 to 18 minutes. Once done, remove from the oven and let them stand for 5 minutes to settle.
- Serve: Serve the ham and cheese croissants warm for the best flavor and texture. Enjoy as a hearty breakfast or brunch option.
Notes
- You can substitute Swiss cheese with Gruyère or Havarti for variation.
- Ensure the croissants are fresh or thawed completely if using frozen for best results.
- The egg white wash helps create a glossy finish and helps the poppy seeds stick.
- For added flavor, add a slice of tomato or a few spinach leaves inside before baking.
- Leftover croissants can be reheated in the oven to maintain crispiness.
