Panko-Crusted Sand Sole with Lemon Maître d'Hôtel Butter and Lively Red Onion Salad

A clean, homestyle fish dish: sand sole fillets lightly coated in panko, crisp without heaviness, topped with lemon maître d'hôtel butter. A small red onion, herb, and white vinegar salad brings the acidity that keeps the fish at the center.

Ingredients

  • 300 g very fresh sand sole fillets, skinless, or common sole fillets
  • 80 g Japanese panko breadcrumbs
  • 40 g all-purpose flour
  • 1 piece fresh egg
  • 70 g lemon maître d'hôtel butter
  • 1 piece untreated lemon
  • 1 piece red onion
  • 1 tbsp white wine vinegar
  • 2 tbsp extra-virgin olive oil
  • 1/2 tsp smoked sweet paprika
  • 1 pinch ground cayenne pepper
  • 0.5 bunches fresh chives
  • 0.5 bunches fresh flat-leaf parsley
  • to taste fine salt
  • to taste freshly ground black pepper

Method

  1. Pat the sand sole fillets very carefully dry with paper towels. Salt them lightly and let them rest in the refrigerator while you prepare the rest: the surface should become matte, never waterlogged.
  2. Prepare the lemon maître d'hôtel butter, or check the prepared component. It should be cold but sliceable when you plate, so it melts slowly over the hot fish.
  3. Finely slice the red onion. Mix it with the white wine vinegar, some of the lemon juice, salt, and pepper. Let it relax while the fish is prepared: the onion should become softer, glossy, and less aggressive.
  4. Add the olive oil, snipped chives, and a little parsley to the seasoned onion. Taste: the accompaniment should be bright, herbaceous, and tart, neither sweet nor dominant.
  5. Prepare three shallow dishes: flour, beaten egg, then panko mixed with smoked sweet paprika, cayenne pepper, and a pinch of salt. The panko should remain dry and light.
  6. Pass each fillet through the flour, tap off the excess, then dip it in the beaten egg and finally in the panko. Press very gently with your palm: the breading should adhere without crushing the flesh.
  7. Heat a wide skillet over medium heat with a drizzle of olive oil and a small knob of butter, if desired. The fat is ready when it gently shimmers and the butter foams without browning too quickly.
  8. Cook the breaded fillets presentation side first. Do not move them at the beginning: the crust needs to set. Turn them when the underside is golden, the edges of the fish have drawn in slightly, and the breading makes a dry sound under the spatula.
  9. Finish cooking on the other side until the flesh is just opaque and separates into moist flakes when pressed. Remove immediately to a rack or warm plate to preserve the crispness.
  10. Off the heat, place a round of maître d'hôtel butter on each still-hot fillet. Wait until it begins to melt and perfume the breading, then add a few drops of fresh lemon.
  11. Plate the fish in the center of the dishes. Place the red onion and herb salad beside it, never over the entire breading. Finish with a little lemon zest, black pepper, and a few chive stems.
