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, for extra flavor.
Step 3: Layer 2 slices of ham and 2 slices of cheese inside each croissant. Close the croissants and place them on the prepared baking sheet.
Step 4: Brush the tops of the croissants lightly with melted butter to achieve a golden, crisp finish.
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 your delicious baked croissants.

Tips & Variations

For a richer taste, substitute Swiss cheese with Gruyère or add a sprinkle of fresh herbs like thyme before baking.
Try swapping ham with turkey or chicken for a different flavor profile.
Spread a little honey mustard instead of Dijon mustard and mayonnaise for a sweeter twist.

Storage

Store leftover baked croissants in an airtight container in the refrigerator for up to 2 days. Reheat in the oven at 350°F (175°C) for about 5-7 minutes to restore crispness and warm the filling thoroughly.

How to Serve

Each croissant is cut in half and filled with slices of pink ham and creamy white cheese, making three main layers: the shiny croissant top layer, the soft ham middle layer, and the smooth cheese bottom layer. Black poppy seeds are sprinkled generously over the croissants, adding a contrasting color and texture. The background is a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

Croissants and Fillings

4 large croissants, sliced in half
8 slices of deli ham (about 200g)
8 slices of Swiss cheese or Gruyère (about 120g)

Spread

2 tbsp Dijon mustard (optional)
2 tbsp mayonnaise (optional)

Finishing

2 tbsp unsalted butter, melted

Instructions

Preheat Oven: Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper to prevent sticking and make cleanup easier.
Prepare Croissants: Slice each croissant in half horizontally. If desired, spread Dijon mustard and mayonnaise on the inside of both halves for added flavor and moisture.
Assemble Fillings: Place 2 slices of deli ham and 2 slices of Swiss cheese inside each croissant half, layering neatly to ensure even melting and taste. Close the croissants carefully to keep the fillings inside.
Prepare for Baking: Arrange the filled croissants on the parchment-lined baking sheet with the closed side down. Brush the tops lightly with melted butter to impart a golden, shiny finish.
Bake: Bake in the preheated oven for 12-15 minutes, or until the croissants are golden brown and the cheese inside is fully melted and gooey.
Serve: Remove from oven and serve the croissants warm to enjoy their flaky texture and savory melted filling at their best.

Notes

For a stronger cheese flavor, substitute Swiss cheese with Gruyère or a mix of both.
You can omit the mustard and mayonnaise for a simpler taste or substitute with your favorite spreads.
Use freshly baked or day-old croissants for best texture.
Serve with a side salad or fresh fruit for a complete meal.
Store any leftovers wrapped in foil and reheat gently in the oven to maintain crispness.
