Preheat the air fryer to 400°F (200°C) for about 3 minutes to ensure a hot, even cooking environment.
Pat the salmon fillets dry with paper towels; this helps the skin crisp up nicely.
Brush the skin side of each fillet lightly with olive oil using a small brush or spoon, ensuring an even coating to promote crispness.
Sprinkle salt, pepper, garlic powder, and chopped dill evenly over the flesh side of the salmon, pressing gently to adhere.
Zest the lemon directly over the seasoned fillets for bright, fresh flavor, and squeeze a little lemon juice over each piece.
Place the salmon fillets skin-side down in the preheated air fryer basket, ensuring they aren’t touching each other for proper air circulation.
Cook the salmon at 400°F (200°C) for 8-10 minutes, or until the skin is golden and crispy, and the flesh is opaque and flakes easily.
Once cooked, carefully transfer the salmon to a serving plate and sprinkle with additional fresh dill and lemon zest for extra aroma and color.
Serve immediately with lemon wedges on the side for an added burst of citrus before enjoying this crisp, flaky salmon.
