Method

Step-by-step

  1. Step 1

    Spread a thin layer of Dijon on the bread and fill with ham and half the Gruyère.

  2. Step 2

    Close the sandwiches and butter the outside lightly.

  3. Step 3

    Toast in a pan until golden on both sides.

  4. Step 4

    Transfer to a tray, spoon béchamel over the top and scatter with the remaining Gruyère.

  5. Step 5

    Grill until bubbling and browned, then serve hot.

    Look for: crisp bread below a bubbling, browned cheese-and-béchamel crown Tip: Keep the sauce thick enough to sit on top rather than run down the sides. Avoid: using too much béchamel so the sandwich turns heavy and soggy
Storage

Make ahead and storage

Storage

Store prepared fillings separately in the refrigerator and assemble as close to serving as possible.

Make ahead

Prepare sauces, pickles and cooked fillings ahead where practical; refresh, reheat or toast just before assembly.
