In a medium mixing bowl, combine the soy sauce, honey (or maple syrup), grated ginger, minced garlic, sesame oil, and rice vinegar. Whisk together until the mixture is well blended; this will serve as your flavorful marinade.
Arrange the salmon fillets in a shallow dish and evenly pour the marinade over each one, ensuring that every fillet is thoroughly coated. Cover the dish with plastic wrap and refrigerate for 30 minutes, allowing the flavors to deeply penetrate the salmon.
Preheat your oven to 400°F (200°C) to prepare for baking.
Line a baking sheet with parchment paper for easy cleanup and to prevent sticking. Arrange the marinated salmon fillets on the baking sheet, placing them skin side down. Set aside the remaining marinade that will be used later.
Bake the salmon in the preheated oven for approximately 15-18 minutes, adjusting the time based on the thickness of your fillets. The salmon should be opaque and flake easily with a fork when done.
While the salmon bakes, pour the reserved marinade into a small saucepan. Heat it over medium heat and bring it to a simmer. Allow it to reduce and thicken for about 5-7 minutes, stirring occasionally.
Once the salmon is finished baking, carefully remove it from the oven. Drizzle the thickened glaze generously over each fillet for added flavor.
For a finishing touch, garnish the glazed salmon with finely chopped green onions and a sprinkle of sesame seeds right before serving.
Notes
For an appealing presentation, serve the glazed salmon on a fluffy bed of jasmine rice or alongside vibrant steamed vegetables.
