Prepare the salmon by patting it dry with paper towels. This crucial step ensures the glaze adheres well and helps achieve that perfect exterior texture.
Make the miso glaze by combining miso paste, maple syrup, soy sauce, rice vinegar, ginger, garlic, and sesame oil in a small bowl. Whisk until smooth and well incorporated.
Coat the salmon generously with the miso mixture, ensuring all sides are covered. For the best flavor, allow it to marinate for 5-10 minutes if time permits.
Preheat your air fryer to 380°F (190°C) for 3 minutes. This ensures the salmon starts cooking immediately when placed inside.
Lightly spray the air fryer basket with cooking spray or brush with a thin layer of oil to prevent sticking.
Place the salmon in the air fryer basket, skin-side down if using skin-on fillets, making sure the pieces don’t touch each other.
Cook for 7-10 minutes depending on thickness and desired doneness. For medium salmon, cook until the internal temperature reaches 125-130°F. There’s no need to flip the fish during cooking.
Check for doneness by gently inserting a fork into the thickest part – it should flake easily but still look moist.
Garnish with sliced green onions and a sprinkle of sesame seeds before serving for added flavor and visual appeal.
