1-Prepare the Miso Butter Compound: In a medium bowl, combine 6 tablespoons softened unsalted butter, 3 tablespoons white miso paste, 1 tablespoon brown sugar, 2 teaspoons grated fresh ginger, 1-2 cloves minced garlic, and 2 tablespoons thinly sliced green onions. Mash with a fork until thoroughly mixed and completely combined. The mixture should be smooth with small pieces of visible aromatics.

2-Prepare and Coat the Salmon: Take your four 6 oz salmon fillets and pat them dry with paper towels. This step ensures that the miso butter will adhere properly and promotes better browning during cooking. Let the salmon sit at room temperature for about 15 minutes before proceeding, which helps it cook more evenly.
Divide the miso butter evenly over the surface of each salmon fillet, spreading to cover completely. If your fillets have skin, place them skin-side down on your baking sheet or air fryer basket. The butter will melt during cooking, infusing the fish with flavor and creating a delicious glaze.

3-Choose Your Cooking Method: This recipe offers two convenient cooking methods, both yielding excellent results with slightly different textures. The choice between oven and air fryer depends on your equipment and personal preference.

4-Oven Method:
1. Preheat oven to 375°F (190°C).
2. Place salmon in a baking dish or oven-safe skillet.
3. Bake for 12-15 minutes until the salmon is opaque and nearly cooked through.
4. Finish by broiling on high for 1-2 minutes to caramelize the top, watching closely to prevent burning.

5-Air Fryer Method:
1. Preheat air fryer to 400°F (200°C).
2. Line the basket with parchment paper or foil for easy cleanup.
3. Place salmon fillets in the basket without overcrowding.
4. Cook for 9-10 minutes without turning the fish.

6-Final Touches and Serving: Once cooked, immediately transfer the salmon to a serving platter using a spatula. Be gentle, as the fish will be delicate and flaky. Drizzle with any remaining miso butter from the pan.
Garnish with additional thinly sliced green onions and a sprinkle of sesame seeds for color and texture contrast. Serve immediately with steamed rice and vegetables for a complete meal.
