01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease with cooking spray.
02 - In a small saucepan over medium heat, combine soy sauce, honey, rice vinegar, mirin, ginger, garlic, and sesame oil. Bring to a gentle simmer.
03 - Stir in the cornstarch slurry and cook for 1-2 minutes, stirring constantly, until the glaze thickens to a glossy consistency. Remove from heat.
04 - Arrange salmon fillets on the prepared baking sheet, skin-side down. Brush generously with half of the teriyaki glaze, ensuring even coverage.
05 - Bake for 12-15 minutes until salmon flakes easily with a fork and reaches an internal temperature of 145°F.
06 - Remove salmon from the oven. Brush with the remaining teriyaki glaze for a glossy finish.
07 - Sprinkle with sliced green onions and toasted sesame seeds. Serve immediately with lemon wedges on the side.
