Make the Marinade: In a small blender or food processor, process all sauce ingredients until smooth. (I like to do it this way because miso can be thick, so blending really makes the sauce cohesive).
1/4 cup miso paste, 3-4 Tbsp shoyu or soy sauce, 2 Tbsp brown sugar, 1 tsp. honey, 1 ½ Tbsp mirin, 1 Tbsp rice vinegar, 2 tsp sesame oil, 2 tsp avocado oil or vegetable oil, 1 tsp. garlic, 1 tsp. fresh ginger, 1/4-1/3 cup water
Marinate the Salmon: Pat salmon dry and place in a dish or zip-top bag. Pour a little more than half of the glaze over the salmon, reserving the rest for later. Marinate for at least 15-30 minutes, or up to 2 hours. Start Timer
4 salmon fillets
Bake: Preheat the oven to 425°F. Line a baking sheet with foil and place an oven-safe wire rack on top. Lightly grease the rack to prevent sticking. Arrange the marinated salmon fillets on the rack leaving the excess marinade behind, skin-side down (if using skin-on). Bake for ~10 minutes, or until the salmon is mostly cooked and just beginning to turn opaque. Start Timer
Broil to finish: Remove from the oven and brush the tops with a light layer of the reserved glaze. Switch the oven to broil (high) and return the pan to the oven. Broil for 3-4 minutes, or until the glaze and salmon are caramelized and slightly charred in spots. Watch closely to prevent burning. Remove from oven and let rest for a couple of minutes. Start TimerNote: For internal temp, the USDA recommends an internal temperature of 145°F. But most chefs would argue that the 130°F range is best. Use your best judgment and note that the temperature will rise more as it finishes cooking when you pull it out of the oven. Serve: Top with green onions, any more of the glaze, sesame seeds, or chili flakes. Serve with rice, noodles, or veggies.
