Pat the salmon fillets dry with paper towels to remove excess moisture, ensuring a crispy skin.
Brush the skin side of each fillet lightly with olive oil using a kitchen brush; this helps achieve a golden, crispy exterior.
Sprinkle the fillets generously with salt, pepper, lemon zest, and chopped fresh herbs, pressing them gently into the flesh for flavor.
If using garlic, evenly scatter the minced garlic over the fillets now to prevent burning during cooking.
Place the salmon fillets skin-side down carefully into the air fryer basket, trying not to disturb the herb crust.
Set the air fryer to 400°F (200°C) and cook for about 8-10 minutes, until the skin is crispy and the flesh feels firm but still moist.
Once cooked, gently press the fillet with a spatula to check for a crackling, crispy skin; it should shatter slightly under pressure.
Carefully transfer the salmon fillets onto a serving plate, skin-side up to keep the crispness intact.
Squeeze fresh lemon wedges over the fish just before serving to add a bright, citrusy aroma that complements the herbs.
Serve immediately with your favorite side dishes and enjoy the crispy, herbaceous flavor of this simple yet elegant dish.
