Ingredients

Scale

For the 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

For the Sandwiches

12 croissants (halved horizontally)
1 pound thinly sliced smoked deli ham
12 slices Swiss cheese (diagonally sliced)

For the Topping

1 large egg white
2 teaspoons poppy seeds

Instructions

Preheat Oven: Preheat your oven to 375 degrees F (190 degrees C). Lightly oil a 9 x 13 baking dish or coat it with nonstick spray to prepare for baking.
Prepare Butter Mixture: In a small bowl, combine the unsalted butter, Dijon mustard, thinly sliced green onions, and honey. Season the mixture with sea salt and black pepper to taste and mix well until smooth.
Assemble Croissants: Spread the prepared butter mixture evenly on each side of the halved croissants. Then layer each with smoked deli ham and a slice of Swiss cheese to assemble 12 sandwiches.
Arrange in Baking Dish: Place each filled croissant in a single layer into the prepared baking dish, ensuring they sit snugly but not overcrowded.
Prepare Egg Wash & Add Topping: In a small bowl, whisk together the egg white with 1 tablespoon of water. Brush the tops of the croissants generously with this egg wash, then sprinkle the poppy seeds evenly over each croissant for added texture and a decorative touch.
Bake: Bake the croissants in the preheated oven for about 15 to 18 minutes or until they turn golden brown and the cheese is melted and bubbly.
Rest & Serve: Remove the croissants from the oven and let them stand for 5 minutes to settle. Serve warm and enjoy your delicious ham and cheese croissants!

Notes

You can substitute Dijon mustard with spicy brown mustard for a different flavor profile.
For extra crispiness, broil the croissants for 1-2 minutes at the end of baking, watching carefully to prevent burning.
These croissants can be prepared a few hours ahead and warmed up before serving.
Use day-old croissants if available for better texture after baking.
Leftovers should be refrigerated and consumed within 2 days; reheat in an oven or toaster oven to maintain crispness.
