Pat the salmon fillets dry thoroughly with paper towels to remove excess moisture, which helps achieve crispy skin.
Mix soy sauce, honey, garlic powder, sesame oil, and black pepper in a small bowl to create your glaze.
Using a basting brush, generously brush the salmon fillets with the soy glaze, ensuring the surface is shiny and well-coated.
Lightly spray the air fryer basket with oil to prevent sticking, then place the glazed salmon filts skin-side down inside.
Preheat the air fryer to 400°F (200°C) if your model requires preheating, then cook the salmon for about 10-12 minutes, until the skin is crispy and golden, and the flesh flakes easily.
Optionally, open the air fryer and brush additional glaze on the salmon for extra shine and flavor, then cook for another 1-2 minutes if desired.
Once done, carefully remove the salmon from the air fryer and let it rest for a minute. Garnish with chopped green onions or sesame seeds if using.
Serve immediately, enjoying the crispy skin and tender, flavorful flesh with the glossy soy glaze.
