Whisk together maple syrup, soy sauce, smoked paprika, Dijon mustard, minced garlic, balsamic vinegar, liquid smoke, black pepper, and sea salt in a small bowl. Stir until the mixture becomes smooth and all spices dissolve completely into the liquid. This glaze is the heart of your summer BBQ success.
Pat salmon fillets dry with paper towels and brush both sides lightly with olive oil. Season skin-side with sea salt and black pepper. Drying the fish ensures proper searing and prevents steaming on the grill.
Preheat your grill to medium-high heat (around 400°F) for 5-7 minutes until the grates are hot and clean. Oil the grates with a paper towel dipped in olive oil to prevent sticking. CIA-level precision here means your grill is ready before your fish touches the surface.
Place salmon skin-side down on the hot grates and cook for exactly 5-6 minutes without moving it. During this time, brush the flesh-side generously with the maple glaze. The smoky maple grilled salmon recipe depends on this undisturbed cooking to develop that crispy skin.
Flip the fillets carefully and brush the skin-side with remaining glaze. Cook for another 5-6 minutes until the flesh flakes easily with a fork and reaches an internal temperature of 145°F. Fresh thyme sprigs and lemon slices can be placed on top during the final 2 minutes.
Transfer salmon to a serving platter and drizzle any remaining glaze over the top. Let it rest for 2 minutes before serving to allow the juices to redistribute through the fish.
