01 - Preheat oven to 400°F. Line a baking sheet with parchment paper and set aside.
02 - In a small saucepan over medium heat, combine tamari, maple syrup, rice vinegar, sesame oil, garlic, and ginger. Bring the mixture to a gentle simmer.
03 - Whisk in the cornstarch slurry and cook for 1 to 2 minutes, stirring constantly, until the sauce thickens to a glossy glaze. Remove from heat.
04 - Arrange salmon fillets on the prepared baking sheet. Brush each fillet generously with the teriyaki glaze using a pastry brush.
05 - Bake for 12 to 15 minutes until the salmon is opaque and flakes easily with a fork. For extra caramelization, broil for the final 2 minutes.
06 - Drizzle the remaining teriyaki sauce over the fillets. Sprinkle with toasted sesame seeds and sliced green onions. Serve with lemon wedges alongside steamed rice or sautéed vegetables.
