Salmon Buried in Potatoes

This is a clever French-inspired technique: skinless salmon fillets sandwiched between layers of shredded potato, sealed tight in foil, and roasted hot. The potatoes steam and insulate the fish, locking in moisture so the salmon stays perfectly medium while the potatoes soften into a tender jacket. A final broil browns the outside into golden-crisp crust.

The foil-then-broil is the trick. Baking alone gives you soft, pale potatoes; skipping the foil dries the fish. The sequence gives you both at once: juicy salmon inside, golden crust outside.

Shred the potatoes just before assembling, or they’ll oxidize to gray. The lemon juice tossed with the shreds helps keep them bright and adds a subtle tang that plays well against the rich fish.

The beurre blanc on the side is a classic French restaurant move. Shallots, white wine, and white wine vinegar reduce to a syrupy base, then cold butter whisked in creates a silky emulsion that pours beautifully over each portion.

Chef Tips

• Press the potato packet firmly before sealing so the shreds adhere to the fish and don’t fall off when unwrapped.
• Squeeze shredded potatoes gently in a towel to remove excess water; soggy potatoes won’t brown under the broiler.
• Keep the beurre blanc warm but never boiling; high heat breaks the emulsion.
• Use a cold knife to slice portions so the crust doesn’t drag.

Variations

• Try the same technique with Arctic char, steelhead, or a thick cod fillet.
• Swap russets for sweet potatoes for a different flavor and color.
• Add fresh dill or tarragon to the potato shreds for a more herbaceous profile.
