01 - Preheat oven to 400°F. Line a baking sheet with parchment paper or lightly grease.
02 - In a small saucepan, combine soy sauce, honey, rice vinegar, mirin, ginger, garlic, and sesame oil. Bring to a simmer over medium heat.
03 - Stir in the cornstarch slurry and cook, stirring, until the glaze thickens (about 1-2 minutes). Remove from heat.
04 - Arrange salmon fillets on the prepared baking sheet, skin-side down. Brush generously with half of the teriyaki glaze.
05 - Bake for 12–15 minutes, or until salmon flakes easily with a fork and is just cooked through.
06 - Remove salmon from the oven and brush with the remaining teriyaki glaze.
07 - Garnish with green onions and sesame seeds. Serve with lemon wedges.
