Salmon with Potato "Scales"

This stunning salmon with potato scales is a sophisticated take on a classic fish supper. By layering thinly sliced, buttered potatoes over fresh salmon fillets, you create a beautiful, lattice-like crust that crisps up perfectly in the frying pan. It is an impressive high-protein dish that combines the succulent texture of oven-roasted fish with the irresistible crunch of golden, buttery potatoes. The contrast of the salty skin and the earthy potato makes every bite a balanced delight.

Perfect for an elegant dinner party or a special weekend treat, this recipe showcases how a few simple ingredients can be transformed with a little technique. It is a wonderful way to serve heart-healthy salmon, providing a boost of omega-3s alongside essential nutrients. Serve these fillets with a wedge of fresh lemon and a side of steamed seasonal greens or a crisp watercress salad for a light yet satisfying meal that looks as good as it tastes.

Ingredients for Salmon with Potato "Scales"

  • 2 (900g ) pieces centre-cut salmon fillet

  • 1 teaspoon salt

  • 1 teaspoon freshly ground black pepper

  • 2 large russet (baking) potatoes (about 675g total)

  • 1 stick (120ml ) unsalted butter, melted

  • 2 tablespoons olive oil

  • Lemon slices for serving

  • An adjustable-blade slicer

  • a 1- to 1 1/2-inch round biscuit cutter

  • two slotted spatulas (see Cooks' notes)

Trim 1 to 2 inches off thinner (belly) side of salmon fillets so that remaining fillets have a more even thickness. Reserve the belly strips for another use. You will now have 2 more square-shaped pieces of salmon fillet. Cut each fillet into 4 roughly equal-size pieces for a total of 8 pieces.

Arrange fish, skin side down, on a baking sheet (or 2 dinner plates). Season with 1 teaspoon each salt and pepper.

Scrub potatoes well. Cut several 1/16-inch-thick slices lengthwise from wider side of 1 potato with slicer (discard outer piece or pieces that are all peel). Stack slices of potato and cut out as many rounds as possible with biscuit cutter.

Dip potato rounds, one at a time, in butter and lay slices on top of one piece of fish in an overlapping pattern (to resemble fish scales), covering surface completely. Continue cutting and stacking a few potato slices at a time and cutting and applying potato "scales" to fish in batches, until tops of all pieces of fish are coated. Lightly brush any remaining butter over scales, and chill until butter is firm, about 1 hour.

Preheat oven to 204°C with rack in middle. Line a large rimmed sheet pan with foil.

Heat oil in a 12-inch nonstick skillet over medium heat until it shimmers (dip a corner of a fish fillet into skillet to test; it should sizzle). Add 2 to 3 pieces of fish, potato sides down, to skillet. Cook until potatoes are golden brown and crisp, 2 to 4 minutes. Carefully turn fish over using 2 spatulas and cook until skin is golden and crisp, about 2 minutes. Carefully transfer fillets (again using 2 spatulas), skin sides down, to sheet pan. Brown remaining fillets.

Roast fish in oven until just cooked through, 4 to 8 minutes (depending on thickness; a possible visual clue—the better quality the salmon, the less likely you'll see it—is when the white albumin in the fish exudes from the fish and begins to set).
