Pat the salmon fillets dry with paper towels to remove excess moisture, ensuring the skin will crisp properly.
In a small bowl, whisk together the juice of half a lemon, minced garlic, olive oil, and a pinch of salt and pepper to create the marinade.
Brush the lemon garlic mixture generously over the salmon fillets, coating all sides and especially the skin.
Preheat the air fryer to 400°F (200°C) for about 3 minutes. Place the fillets skin-side down in the air fryer basket, feeling their weight settle onto the surface.
Cook the salmon for 10-12 minutes, listening for the gentle sizzle and crackle of the skin crisping up as it cooks.
Once cooked, carefully remove the fillets using tongs, ensuring the skin is golden and crispy, and the inside is tender and flaky.
Squeeze fresh lemon juice over the cooked fillets and sprinkle with chopped parsley or dill for a burst of fresh flavor.
Serve immediately, allowing the crispy skin, smoky garlic aroma, and bright lemon zest to shine through in every bite.
