Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease it with oil.
Make the glaze: In a small bowl, whisk together the hoisin sauce, soy sauce, honey, rice vinegar, sesame oil, garlic, ginger, and sriracha (if using).
Prepare the salmon: Pat the salmon fillets dry with a paper towel and place them on the prepared baking sheet. Brush the salmon generously with the hoisin glaze, ensuring each fillet is well-coated.
Bake the salmon: Place the salmon in the preheated oven and bake for 12-15 minutes, or until the salmon flakes easily with a fork and is cooked through.
Garnish and serve: Remove the salmon from the oven and sprinkle with sesame seeds and green onions. Serve immediately with your choice of sides like steamed rice, quinoa, or stir-fried vegetables.
