Directions

Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a medium bowl, combine the Gruyère cheese, cream cheese, chives, parsley, salt, and pepper. Mix until well combined.
Unroll the croissant dough and separate it into individual triangles.
Place a tablespoon of the cheese and herb mixture at the wide end of each triangle.
Roll up each triangle, starting from the wide end, and place them on the prepared baking sheet, seam side down.
Brush the tops of the croissants with the beaten egg to ensure a golden brown finish.
Bake in the preheated oven for 12-15 minutes, or until the croissants are golden brown and the cheese is melted and bubbly.

Allow to cool slightly before serving.

Variations & Tips

For a different flavor profile, try using a combination of cheeses such as cheddar and mozzarella. You can also experiment with different herbs like thyme or rosemary for a more aromatic touch. For a spicy kick, add a pinch of red pepper flakes to the cheese mixture. If you prefer a meatier option, consider adding thin slices of ham or prosciutto to the filling. For a vegetarian twist, add sautéed mushrooms or spinach to the cheese mixture.
