Equipment

  • Paper towels
  • Bowl
  • Medium pot
  • Shallow ramekins
  • Small spatula
  • Baking tray

Instructions

Preparation

  1. Step 1: Preheat the oven to 200°C / 400°F (180°C fan-forced).

  2. Step 2: Pat the scallops dry with paper towel. Remove the little side muscle, or “foot,” if present; it is edible but can get chewy when cooked. Set the scallops aside.

  1. Step 4: Melt the butter in a medium pot over medium heat. Add the eschalot and mushrooms. Stir regularly and cook for 4–5 minutes, until the mushrooms are soft.

  2. Step 5: Add the flour. Stir and cook for 30 seconds; the mixture will look a bit pasty.

  3. Step 6: Pour in the hot milk and cream. Stir until incorporated and lump-free.

  4. Step 7: Add the salt, pepper and nutmeg, then stir well. When the first small bubbles appear, cook for 30 seconds and take the pot off the heat. The béchamel should be more pourable than a regular béchamel so it spreads easily around the scallops.

Assemble

  1. Step 8: Season the scallops with salt and divide them among 4 shallow ramekins. The recipe uses flat round ramekins about 11 cm / 4.3 inches in diameter and 2.5 cm / 1 inch deep.

  2. Step 9: Cover the scallops with all the mushroom béchamel, filling the gaps. Flatten the surface with a small spatula or the back of a spoon.

  3. Step 10: Scatter the cheesy crust evenly over each ramekin, right to the edges, with no empty spots.

  5. Step 12: Rest for 2 minutes, then serve.

Notes

Notes

For medium scallops, cut each one in half; keep small scallops whole or cut large scallops into three pieces so they cook evenly. Thaw frozen scallops before using. The recipe notes allow about 2 hours for thawing, but do not include that time in the preparation estimate.

If needed, substitute regular breadcrumbs for panko. Swiss or Emmental cheese is the closest alternative to Gruyère; mild melting cheeses are also listed as options. Brown onion can replace the eschalot.

The gratins are best fresh. Refrigerate leftovers for up to 2 days and reheat in a 180°C / 350°F fan oven for 15 minutes or until hot through and crisp on top. Freezing is not recommended.
