Ingredients

4 large croissants, sliced in half
8 slices of deli ham (about 200g)
8 slices of Swiss cheese or Gruyère (about 120g)
2 tbsp Dijon mustard (optional)
2 tbsp mayonnaise (optional)
2 tbsp unsalted butter, melted

Instructions

Step 1: Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper.
Step 2: Spread Dijon mustard and mayonnaise on the inside of each croissant half if using.
Step 3: Layer 2 slices of ham and 2 slices of cheese inside each croissant half. Close the croissants and place them on the prepared baking sheet.
Step 4: Brush the tops of the croissants lightly with melted butter.
Step 5: Bake in the preheated oven for 12-15 minutes or until the cheese is melted and the croissants are golden brown.
Step 6: Serve warm and enjoy!

Tips & Variations

For added flavor, try adding a few slices of tomato or a sprinkle of fresh herbs like thyme or parsley inside the croissants before baking.
Substitute Swiss cheese with cheddar or mozzarella for a different cheese experience.
If you prefer a crispier top, brush the croissants with an egg wash instead of butter before baking.

Storage

Store any leftover baked croissants in an airtight container in the refrigerator for up to 2 days. Reheat in a preheated oven at 350°F (175°C) for 5-7 minutes to restore crispiness and melt the cheese. Avoid microwaving, as it can make the croissant soggy.
