Preheat oven to 375°F. Line a large baking sheet with parchment. Pat the salmon dry and place skin side down on the parchment-lined baking pan.
In a small bowl, whisk together the remaining ingredients to make the sauce. Brush or spoon the sauce over the salmon.
Bake for 18-24 minutes, until the internal temperature reads 135°F and flakes easily with a fork.
Turn the oven to broil and broil until the top of the salmon begins to crisp up slightly. Sprinkle sliced green onion and sesame seeds over top and serve.
Notes
Storage: Store in an airtight container in the refrigerator for up to 3 days.Temperature: The salmon will continue to cook after it's removed from the oven, so to avoid over cooking you want to remove the salmon from the oven before it reaches the recommended internal temperature of 145°F. This way you'll have a firm, flakey fillet that's juicy not dry.
