Step 1: Preheat the Oven

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 over medium heat, combine the soy sauce, honey, rice vinegar, sesame oil, garlic, and ginger.
2. Bring to a gentle simmer, stirring occasionally.
3. Mix 1 teaspoon cornstarch with 1 tablespoon water in a small bowl, then add it to the sauce. Stir until the sauce thickens slightly (about 2 minutes).
4. Remove from heat and let it cool slightly.

Step 3: Prep the Salmon

1. Pat the salmon fillets dry with paper towels to remove excess moisture.
2. Place them on the prepared baking sheet, skin-side down.
3. Brush each fillet with olive oil, then sprinkle with salt and black pepper.

Step 4: Glaze and Bake the Salmon

1. Brush half of the teriyaki sauce over the salmon fillets, coating them evenly.
2. Bake for 12–15 minutes, or until the salmon flakes easily with a fork. (Tip: Thicker fillets may need up to 18 minutes.)
3. In the last 2 minutes of baking, brush the salmon with the remaining teriyaki sauce to create a thick, caramelized glaze.

Step 5: Garnish and Serve

1. Remove from the oven and sprinkle with sesame seeds and green onions (if using).
2. Serve hot with steamed rice, roasted vegetables, or a fresh salad.
