Grilled Salmon with Lemon & Thyme

This salmon gets treated more like a cure than a marinade. Cognac rubbed over both sides, then a paste of lemon zest, kosher salt, brown sugar, fresh thyme, minced shallots, and black pepper pressed onto the fish. Weighted down and refrigerated for at least six hours, the salt and sugar partially cure the flesh, firming the texture and driving flavor deep into the fillet.

That overnight press under a weighted baking sheet is the key technique. The pressure forces the cure into the salmon while drawing out moisture, concentrating the fish flavor and giving it a firmer, silkier texture that holds up beautifully on the grill.

Three minutes per side over medium-high heat is all you need. The cured surface caramelizes fast, forming a golden, aromatic crust while the interior stays moist.

Chef Tips

• Use a generous amount of lemon zest. A quarter cup sounds like a lot, but it’s what gives the cure its punch against the rich salmon.
• Kosher salt is a must here. Fine table salt dissolves too quickly and over-salts the fish during the long cure.
• Weight the salmon evenly. A second baking sheet topped with a cast iron skillet works perfectly.
• Pat the fillets dry before grilling. Excess moisture from the cure steams instead of searing on the grill.

Variations

• Dill and gin: Swap the Cognac for gin and the thyme for fresh dill for a Scandinavian-style gravlax approach.
• Oven alternative: Roast at high heat for 10 to 12 minutes if grilling isn’t an option.
