• Step 1: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or a silicone baking mat.
• Step 2: In a small bowl, whisk together the miso paste, honey, soy sauce, rice vinegar, sesame oil, garlic, and ginger until well combined.
• Step 3: Place the salmon fillets on the prepared baking sheet and spoon the miso mixture evenly over the top of each fillet, making sure to coat them thoroughly.
• Step 4: Bake the salmon for 12-15 minutes, or until the fish is cooked through and the glaze is caramelized and bubbling.
• Step 5: Remove the salmon from the oven and let it rest for 5 minutes before serving. Sprinkle with the optional red pepper flakes if desired.
