Béchamel Sauce
- ¼ cup unsalted butter (½ stick)
- ¼ cup all-purpose flour
- 1½ cups whole milk
- Salt and freshly ground black pepper, to taste
- ¼ teaspoon Dijon mustard
- Dash of ground nutmeg
Sandwiches
- 8 thin slices white sandwich bread
- 5 ounces good quality ham (about 8 slices)
- 6 ounces Gruyere cheese, or Emmental cheese, grated (about 2½ cups)
- ¼ cup freshly grated Parmesan cheese
- Make Béchamel Sauce: In a medium saucepan over medium heat, melt the butter. Whisk in the flour and cook, stirring constantly, for about 3 minutes to form a roux. Gradually add the whole milk, whisking continuously until the mixture is smooth. Continue cooking and stirring until the sauce thickens to a creamy consistency.
- Season Sauce: Remove from heat and season with salt and freshly ground black pepper to taste. Whisk in the Dijon mustard and a dash of ground nutmeg for added flavor. Set the béchamel sauce aside while you assemble the sandwiches, or refrigerate for up to 1 week if preparing in advance.
- Preheat Oven: Preheat your oven to 425°F (220°C). Line a baking tray with parchment paper and set it aside for assembling the sandwiches.
- Prepare Bread: Spread each slice of bread evenly with a layer of the béchamel sauce, covering the surface all the way to the edges to ensure maximum creaminess.
- Assemble Sandwiches: Arrange four of the bread slices, béchamel side up, on the prepared baking tray. Top each with one slice of ham, a generous handful of grated Gruyere cheese, and a sprinkle of grated Parmesan cheese.
- Complete Sandwiches: Place the remaining four slices of bread on top of the cheese layer, béchamel side up. Then, evenly distribute the remaining Gruyere and Parmesan cheese on top of the sandwiches.
- Bake: Place the baking tray in the preheated oven and bake for about 5-6 minutes, or until the cheese has melted thoroughly.
- Broil for Finish: Switch your oven setting to broil and broil the sandwiches for an additional 2-4 minutes, or until the cheese on top turns lightly golden and bubbly. Watch closely to avoid burning.
- Serve: Remove from the oven and allow to cool slightly before serving warm for a delightful rich and cheesy experience.
Notes
- You can substitute Emmental cheese if Gruyere is unavailable.
- For a lighter version, use low-fat milk instead of whole milk, though the sauce will be less rich.
- To make Croque Madame, top each sandwich with a fried egg after baking.
- Leftover béchamel sauce can be stored in the refrigerator for up to one week.
- Broiling time may vary depending on your oven, so keep a close eye to prevent burning.
