Preheat your air fryer to 400°F (200°C) for about 3 minutes to ensure it's hot and ready.
Pat the salmon fillets dry with paper towels to remove excess moisture, which helps the skin crisp up.
Lightly brush the skin side of each fillet with olive oil using a small brush—this promotes crispiness and helps the seasoning stick.
Generously season the fillets with flaky sea salt and freshly cracked black pepper, making sure to cover the skin for added flavor.
Sprinkle lemon zest and garlic powder evenly over the fillets, then add dried herbs and optional paprika or red pepper flakes for extra flavor.
Place the seasoned fillets skin-side down in the air fryer basket, ensuring they aren’t touching for even cooking.
Cook the salmon at 400°F (200°C) for about 10 minutes. The skin will crackle and turn golden, and the flesh will become opaque and flaky.
Once cooked, carefully remove the fillets from the basket and squeeze fresh lemon juice over the top for brightness.
Serve immediately with your favorite sides, enjoying the crispy skin and tender, flaky interior.
