In a bowl, whisk together the lemon juice, olive oil, Dijon mustard, and honey until the mustard and honey are fully dissolved—this creates an emulsified base that helps the oil and acid blend smoothly rather than separate. Add the minced garlic, lemon zest, parsley, rosemary, thyme, salt, black pepper, and red pepper flakes, stirring well to combine all flavors. I like to let this marinade sit for a minute so the herbs can begin releasing their oils into the liquid, which deepens the flavor profile significantly.

Place the salmon in a shallow dish or zip-top bag. Pour the lemon-herb marinade from Step 1 over the salmon, making sure to coat both sides evenly. Turn the salmon once halfway through to ensure even flavor absorption. Let it marinate for 30 minutes at room temperature—this timeframe is perfect for infusing the herbs and citrus without over-marinating, which can affect the texture.

While the salmon marinates, preheat your grill to medium-high heat (around 400-425°F if you have a temperature gauge). Once it reaches temperature, oil the grill grates thoroughly using a folded paper towel dipped in neutral oil—this prevents sticking and creates those beautiful grill marks. I like to heat the grill for at least 10 minutes so it reaches a true medium-high temperature, which ensures the salmon gets a nice crust without drying out.

Remove the salmon from the marinade, letting excess marinade drip off, and place it skin-side up on the hot grill grates. Cook for 3-5 minutes without moving it—this allows the bottom to develop a flavorful crust. Carefully flip the salmon and cook for another 3-5 minutes on the second side until the flesh is opaque and flakes easily with a fork. The salmon is done when it reaches an internal temperature of 145°F; cooking times vary based on thickness, so adjust accordingly.

Transfer the grilled salmon to a serving platter and let it rest for 2-3 minutes. This short rest allows the juices to redistribute throughout the fish, keeping it moist and tender. Serve warm while the herbs and lemon flavors are still vibrant.
