Grilled Salmon with Lemon Butter Sauce

Introduction

This recipe delivers restaurant-quality grilled salmon in about 30 minutes, with crispy skin and a silky lemon butter sauce that finishes the fish without overwhelming it. The key is high, even heat and a well-oiled grate to prevent sticking while the skin crisps.

Recipe Details

• Prep Time: 10 minutes
• Cook Time: 12–15 minutes
• Total Time: 22–25 minutes
• Servings: 4

Ingredients

• 4 ea. (24 ounces) skin-on Coho salmon fillets
• Olive oil
• Salt
• Freshly-ground black pepper
• 1 stick unsalted butter, softened
• ½ lemon, juiced
• A flame-resistant towel tied with twine and soaked in oil

Instructions

1. Brush salmon with olive oil and sprinkle liberally with salt and freshly ground black pepper. Set aside.
2. Heat a large chimney starter’s worth of charcoal briquets. Once hot, disperse evenly around the bottom of the grill and reapply the grate.
3. Quickly grease the grate with the towel. Add salmon fillets, skin side down, and cook, covered, turning often, until fish is pink throughout and flakes easily when tested with a fork.
4. Remove and keep warm.
5. Fold together lemon and butter. Melt over medium heat in a large saucepan.
6. Drizzle butter over salmon fillets and serve warm.

Variations

Herb butter: Mix fresh dill, parsley, or tarragon into the softened butter before melting for an herbal note that complements salmon without masking its flavor.

Garlic lemon butter: Add 2–3 minced garlic cloves to the butter as it melts, letting them infuse gently for 1–2 minutes to avoid burning.

Orange butter: Replace lemon juice with fresh orange juice for a subtly sweeter, less acidic sauce that pairs well with grilled salmon.

Charred lemon garnish: Skip the butter sauce and instead top each fillet with a half-moon of grilled lemon, charred cut-side down on the grill for 2 minutes, for brightness without richness.

Whole fish: Scale and gut a 2- to 3-pound salmon, season inside and out, and grill skin side down for 20–25 minutes, rotating the grate halfway through to ensure even cooking.

Tips for Success

Oil the grate aggressively. The flame-resistant towel method works well, but be generous—a dry or insufficiently oiled grate will stick and tear the skin.

Keep the grill covered while cooking. A covered grill traps heat and smoke, which cooks the fish through evenly and flavors the skin without drying the flesh.

Test doneness by flaking, not time. Salmon thickness varies, so check by inserting a fork into the thickest part and gently twisting—it should flake easily and look opaque pink, not translucent or chalky white.

Soften the butter ahead. Cut it into small pieces and leave it on the counter for 15–20 minutes before the meal, so folding in the lemon juice is quick and the sauce comes together smoothly.

Watch the butter as it melts. Use medium heat and stir occasionally; butter can brown or separate quickly, and you want it emulsified and glossy, not broken or dark.

Storage and Reheating

Reheat gently in a 275°F oven, loosely covered with foil, for 8–10 minutes until warmed through. Alternatively, flake the salmon into a salad or grain bowl and serve at room temperature with a drizzle of fresh lemon juice.

FAQ

Can I use a gas grill instead of charcoal?

Yes. Preheat all burners to high, oil the grate, reduce heat to medium-high, and follow the same cooking method. Gas grills heat less intensely than charcoal, so add 3–5 minutes to the cook time.

What if I don’t have a chimney starter?

Arrange charcoal in a pyramid shape and light it with a long match or fire starter, waiting 15–20 minutes until the briquets turn white and ash over before spreading them on the grill.

Can I make the butter sauce ahead?

Yes. Mix the softened butter and lemon juice in a bowl up to 2 hours before serving, cover, and refrigerate. Reheat gently in a saucepan over low heat just before serving, or serve cold as a compound butter on top of the warm salmon.

What size salmon fillets work best?

Fillets 1 to 1.5 inches thick cook evenly without drying out. Thinner fillets (under 1 inch) risk overcooking; thicker ones (over 1.5 inches) may char on the outside before the inside finishes.
