Ingredients
Method
Step 1: Prepare the Béchamel Sauce
- Start by making your béchamel.
- In a saucepan over medium heat, melt the butter.
- Once melted, add the flour, whisking constantly for about two minutes until the mixture turns a light golden color.
- Gradually whisk in the milk, ensuring there are no lumps. Cook until it thickens, roughly 5-7 minutes, stirring continuously.
- Stir in the Dijon mustard, nutmeg, and sautéed onions. Season with kosher salt to taste. Set aside.
Step 2: Preheat the Oven
- Set your oven to 375°F (190°C) so it’s ready for baking.
Step 3: Assemble the Croissants
- Slice open each croissant lengthwise.
- Layer the bottom half with slices of ham and a generous helping of Gruyère cheese.
- Spoon some of the béchamel on top of the cheese. It should coat the filling nicely.
- Place the top half of the croissant on each assembled bottom and lightly press down.
Step 4: Bake
- Place the assembled croissants on a baking sheet lined with parchment paper.
- Drizzle some béchamel over the top of each croissant, allowing it to seep in.
- Bake in the preheated oven for about 15-20 minutes. The croissants should be golden brown and the cheese bubbling.
Step 5: Serve and Enjoy
- Allow the croissants to rest for a couple of minutes before serving. Enjoy this wonder with your favorite side salad or drink!
Notes
- Stale Croissants: Day-old croissants work best because they hold up better against baking. Fresh croissants might get too soggy.
- Whisking: When making the béchamel, constantly whisking helps create a smooth sauce. Lumps are a no-go.
- Layering: Don’t skimp on the fillings! Ensure each croissant has enough ham and cheese for that irresistible flavor in every bite.
- Add Veggies: For an extra twist, try incorporating sautéed spinach or mushrooms in the filling for additional flavor and nutrition.
- Make Ahead: You can assemble the croissants ahead of time and bake them just before serving. They reheat beautifully, too!
