In a bowl, combine honey, minced garlic, soy sauce, and grated ginger. Whisk until well mixed.
Place the salmon fillets in a shallow dish and pour the marinade over them. Cover and refrigerate for at least 30 minutes (up to 2 hours for more flavor).
Preheat your oven to 400°F (200°C).
In an oven-safe skillet, heat olive oil over medium-high heat. Remove salmon from the marinade, allowing excess to drip off, and season with salt and pepper. Place the fillets skin-side down in the skillet. Cook for about 4-5 minutes until the skin is crispy.
Carefully spoon some of the reserved marinade over the fillets, then transfer the skillet to the preheated oven. Bake for another 6-8 minutes or until the salmon is cooked through and flakes easily with a fork.
In the last minute of baking, sprinkle sesame seeds over the salmon to toast.
Remove from the oven, garnish with sliced green onions, and drizzle any remaining marinade from the pan over the top.
Notes
For extra flavor, marinate the salmon for up to 2 hours.
