Ingredients
Method
Step 1: Make the Cheese Sauce
- In a saucepan over medium heat, melt the butter. Whisk in the flour and cook for about a minute to develop flavor. Gradually add the heavy cream, stirring continuously. After it thickens slightly, reduce the heat, then add in the Gruyère cheese, pinch of salt, pepper, and nutmeg. Stir until melted and smooth. Set aside.
Step 2: Prepare the Baguette
- Slice the baguette into even slices. You want them thick enough to hold together but thin enough to toast nicely. Lay them out on a baking sheet.
Step 3: Assemble the Sandwiches
- Spread Dijon mustard generously on one side of each baguette slice. Layer thinly sliced ham on half of the pieces. Top that with the freshly grated Gruyère and a sprinkle of Parmigiano-Reggiano cheese.
Step 4: Top It Off
- Place the remaining baguette slices on top of the ham and cheese layers to form sandwiches. Drizzle the cheese sauce generously over each sandwich, allowing it to cascade down the sides.
Step 5: Bake
- Preheat your oven to 375°F (190°C). Bake the assembled sandwiches for about 15 minutes or until the cheese is bubbly and golden.
Step 6: Finish and Serve
- Sprinkle fresh thyme and add herbs for garnish. Slice the sandwiches in half and serve while hot.
Notes
- Use Fresh Ingredients: Always opt for fresh bread and high-quality meats for the best flavor.
- Don’t Rush the Cheese Sauce: Letting the cheese melt slowly creates a smoother sauce.
- Experiment with Cheese: If Gruyère isn’t available, try Emmental or a sharp Cheddar.
- Add a Twist: Consider adding sautéed mushrooms or spinach for extra flavor.
- Serve Immediately: For the best taste, serve right after baking while the cheese is gooey.
