Preheat your grill to medium-high heat (about 400°F/200°C). If using an indoor grill pan, heat it over medium-high heat with a light coating of oil.
In a small bowl, whisk together the olive oil, lemon zest, lemon juice, minced garlic, parsley, dill, oregano, salt, and black pepper to create a marinade.
Pat the salmon fillets dry with paper towels. Brush both sides of the fillets with the marinade, ensuring they’re well coated. Let them sit for 5-10 minutes to absorb the flavors.
Lightly oil the grill grates to prevent sticking. Place the salmon fillets on the grill, skin-side down if applicable. Grill for 5-6 minutes per side, depending on thickness, until the salmon flakes easily with a fork and reaches an internal temperature of 145°F (63°C). Avoid overcooking to keep it moist.
Carefully remove the salmon from the grill using a spatula. If any marinade remains, drizzle it over the cooked fillets for extra flavor.
Transfer the grilled salmon to a serving platter. Garnish with lemon slices if desired. Serve your grilled lemon herb salmon hot, paired with a side of vegetables or salad for a light and flavorful dinner!
