Choosing the Best Salmon for Grilling

Not all salmon is created equal. Here’s how to select the perfect one for grilling:

Wild-Caught vs. Farmed Salmon

  • Wild-Caught Salmon: Richer flavor and higher omega-3 content. Examples include:
    • Sockeye Salmon: Known for its vibrant color and robust flavor.
    • King Salmon: High in fat, making it ideal for grilling.
    • Coho Salmon: A balanced choice with a mild, delicate flavor.
  • Farmed Salmon: Budget-friendly but less flavorful compared to wild-caught options.

How to Prepare a Whole Salmon for the Grill

Preparation is key to achieving perfectly grilled salmon.

Essential Ingredients:

  • 1 whole salmon (Sockeye or King preferred)
  • 1 large lemon, thinly sliced
  • 1 bunch of fresh dill
  • 4 cloves of garlic, minced
  • Salt and pepper to taste
  • 3 tablespoons unsalted butter

Step-by-Step Preparation

  1. Clean the Salmon: Rinse the salmon under cold water and pat it dry with paper towels. Remove any scales with a fish scaler or the back of a knife.
  2. Score the Fish: Make shallow cuts on both sides of the fish for even cooking and better flavor infusion.
  3. Season Generously: Rub the inside and outside with salt, pepper, and minced garlic.
  4. Stuff the Cavity: Fill the cavity with lemon slices and fresh dill for added moisture and flavor.

Grilling a Whole Salmon: Techniques and Tips

Grilling Salmon in Aluminum Foil

Grilling salmon in foil locks in moisture and creates a self-basting effect.

  1. Lay out a large piece of heavy-duty aluminum foil.
  2. Place the seasoned salmon in the center.
  3. Fold the edges of the foil to create a sealed packet.
  4. Grill over medium heat (375°F–400°F) for 45–60 minutes, depending on the size.

Grilling Salmon Directly on the Grates

For a smoky, charred flavor, grill the salmon directly on the grates.

  1. Preheat the Grill: Ensure it reaches 450°F–500°F for even cooking.
  2. Oil the Grates: Use a high-smoke-point oil like grapeseed to prevent sticking.
  3. Start Skin-Side Down: Place the salmon skin-side down and grill for 10–12 minutes.
  4. Flip Carefully: Use a fish spatula to flip and cook for an additional 10 minutes.

Pro Tip: Always start with the skin-side down to create a crispy layer and protect the flesh from overcooking.

How to Check for Doneness

Serving Suggestions for Grilled Salmon

Pair your perfectly grilled salmon with these sides and accompaniments:

  • Vegetables: Grilled asparagus, roasted Brussels sprouts, or sautéed spinach.
  • Grains: Wild rice, quinoa, or couscous.
  • Sauces: A drizzle of garlic aioli, lemon butter sauce, or a tangy dill yogurt dressing.
