Step 1: Preheat the Oven

1. Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or aluminum foil for easy cleanup.

Step 2: Prepare the Teriyaki Sauce

1. In a small saucepan, combine the soy sauce, honey, rice vinegar, sesame oil, minced ginger, and garlic. Heat over medium heat until it begins to simmer.
2. In a small bowl, mix the cornstarch with water to create a slurry. Slowly whisk the slurry into the simmering sauce.
3. Continue to cook for 2–3 minutes, stirring constantly, until the sauce thickens. Remove from heat and set aside.

Step 3: Prepare the Salmon

1. Pat the salmon fillets dry with paper towels. Brush both sides lightly with olive oil, then season with salt and pepper.
2. Place the salmon fillets on the prepared baking sheet, skin-side down if applicable.

Step 4: Glaze and Bake

1. Spoon half of the prepared teriyaki sauce over the salmon fillets, ensuring they are evenly coated. Reserve the remaining sauce for serving.
2. Bake the salmon in the preheated oven for 12–15 minutes, or until the salmon flakes easily with a fork. The internal temperature should reach 145°F (63°C).

Step 5: Garnish and Serve

1. Remove the salmon from the oven and drizzle with the reserved teriyaki sauce. Garnish with sesame seeds and green onions, if desired.
2. Serve immediately with your choice of sides, such as steamed rice, sautéed vegetables, or a fresh salad.
