Pat the salmon fillets dry with paper towels to remove excess moisture and help them crisp up.
Mix the minced garlic, lemon juice, olive oil, salt, pepper, and herbs in a small bowl to create a lemon garlic paste.
Use a brush or your fingers to evenly smear the lemon garlic paste all over the surface of each salmon fillet, ensuring the skin side is well coated.
Preheat the air fryer to 400°F (200°C) for about 3-5 minutes until hot and ready.
Place the salmon fillets skin-side down in the air fryer basket, making sure they aren’t touching to allow even crisping.
Cook the salmon for 8-10 minutes, until the skin is crispy and crackling, and the flesh feels firm when gently pressed.
Halfway through cooking, carefully flip the fillets to ensure even crispness on both sides, then return to the air fryer to finish cooking.
Remove the salmon from the air fryer once the skin is crisp and the flesh flakes easily with a fork.
Serve immediately, garnished with extra lemon slices or herbs if desired, and enjoy the crispy skin and tender, flavorful interior.
