Pat the salmon fillets dry with paper towels to remove excess moisture, ensuring the skin crisps well.
Using a brush or your fingers, lightly coat the skin side of each fillet with olive oil to promote crisping and prevent sticking.
Sprinkle salt, pepper, lemon zest, garlic powder, and smoked paprika evenly over both sides of the fillets, pressing lightly to adhere.
Preheat the air fryer to 400°F (200°C) for about 3 minutes, allowing it to reach the right cooking temperature.
Lay the salmon skin-side down in the air fryer basket, making sure they aren't touching to allow proper air circulation.
Cook for 8-10 minutes, or until the skin is golden and crispy, and the flesh appears opaque and flakes easily when tested with a fork.
Gently lift the salmon using tongs or a fish spatula, being careful to keep the crispy skin intact.
Transfer the salmon to a serving plate and sprinkle with freshly chopped herbs for added flavor and color.
Squeeze fresh lemon juice over the top for a bright, tangy finish before serving.
Enjoy your perfectly crispy, tender salmon with your favorite sides or atop a fresh salad.
