Whisk the marinade
Preheat the oven. Mix the garlic, ginger, honey, tamari, sesame oil, and rice wine vinegar in a bowl.
Prep the salmon
Place the salmon in a bowl and pour in half of the marinade. Gently stir the salmon until it’s completely coated in the sauce. Arrange it on the baking sheet.
Bake and Broil
Pop the salmon into the oven until flaky. Remove it from the oven and turn on the broiler. Broil the salmon until slightly browned. Remove it from the broiler.
Pour the remaining sauce into a small pot over low heat. Whisk the cornstarch and water in a small bowl until smooth to make a slurry. Simmer the sauce and whisk continuously until thickened. Remove it from the heat and set it aside. Brush teriyaki sauce over the salmon to taste. Garnish with sesame seeds and green onions. Enjoy!
