Instructions

Prepare the oven

  1. Step 1: Preheat the oven to 200°C/390°F (180°C fan).

Make the béchamel

  1. Step 2: Place the milk and cream in a saucepan over medium heat. Heat until steaming, but do not let it boil. Set aside.

  2. Step 3: Melt the butter in a separate small saucepan over medium heat, then turn the heat to low. Add the flour and cook, stirring almost constantly, for 3 minutes. Do not let it brown.

  3. Step 4: While stirring, add half the hot milk and cream mixture. Once it is incorporated into the roux, stir in the remaining mixture, nutmeg, salt and pepper.

  4. Step 5: Mix for 30 seconds to 1 minute, or until the sauce thickens to a spreadable, soft butter-like consistency. If there are lumps, whisk until smooth. Remove from the heat; the sauce can cool.

Assemble the sandwiches

  1. Step 6: Spread half the béchamel over all 4 slices of bread, as you would butter bread for a sandwich. Reserve the remaining béchamel for the topping.

  2. Step 7: Top two slices of bread with 2 slices of Gruyère or Swiss cheese each, folding the cheese as needed to fit. Spread half the Dijon mustard over the cheese.

  3. Step 8: Add the ham, then spread it with the remaining Dijon mustard.

  4. Step 9: Top each sandwich with 2 more slices of cheese, folding as needed, then close the sandwiches with the other bread slices.

Pan-fry

  1. Step 10: Melt the butter in a skillet over medium to medium-high heat. Add the sandwiches and cook for 2 minutes, pressing down lightly with a spatula, until deeply golden brown.

  2. Step 11: Turn the sandwiches and cook the other side until golden brown. Transfer them to a baking tray.

Top and bake

  1. Step 12: Spread the reserved béchamel thickly over the top of each sandwich. Sprinkle with Gruyère, then Parmesan.

  2. Step 13: Bake for 15 minutes, then switch to the grill/broiler for 3 minutes, until the top is golden and bubbling.

Serve

  1. Step 14: Transfer the sandwiches immediately to warmed serving plates. Serve with knives and forks, as they are too messy to eat by hand. For a traditional French bistro-style meal, add fries and leafy greens lightly dressed with French dressing or a basic vinaigrette.

Notes

Bread and cheese options

Choose a sturdy bread with a substantial crumb rather than a soft, delicate sandwich loaf. Sourdough without an overly thick or chewy crust is one option; ciabatta or pane di casa also work. If using soft bread, toast it before assembling. Comté, Emmental or another good melting cheese can stand in for the Swiss or Gruyère; the recipe advises against mozzarella.

Make ahead

Assemble the sandwiches, wrap them tightly and freeze for 2 to 3 months. Thaw before cooking.
