Preheat gas or charcoal grill to 450°F - 475°F.

Remove moisture from salmon fillets by patting with a paper towel. Then, use a brush to brush olive oil onto all sides of each salmon fillet.

Generously season salmon fillets with salt and pepper.

Once your grill has fully preheated, place salmon fillets directly on the grill, skin side down, and close the grill.

Grill skin-side down for 6 minutes.

Then, flip the fillets and grill for an additional 2 minutes skin-side up. Ensure the salmon is cooked to an internal temperature of 140°F before removing from the grill. If salmon needs additional time to reach an internal temperature of 140°F, flip back to skin side down and grill for an additional 1 minute at a time.

Remove salmon from the grill and let rest for 5 minutes (internal temperature will continue to increase to 145°F even after being removed from heat).

Remove skin and serve with optional fresh lemon juice.
