Preheat the air fryer: Set it to 390°F (200°C) for 3 minutes.
A hot basket helps the salmon sear lightly on contact.
Prep the salmon: Pat the fillets dry on both sides with paper towels. Dry fish browns better and won’t steam in the basket.
Season: In a small bowl, mix lemon pepper, salt, and garlic powder. Rub salmon with olive oil, then sprinkle seasoning evenly. Add lemon zest over the tops and press gently so it adheres.
Arrange in the basket: Lightly spray or brush the basket with oil.
Place fillets in a single layer, skin-side down if using skin-on. Leave space between pieces for airflow.
Air fry: Cook for 7–10 minutes, depending on thickness. A 1-inch-thick fillet typically takes about 8 minutes. Salmon is done when it flakes easily and reaches 125–130°F for medium or 140°F for well-done.
Finish with lemon: As soon as it’s done, squeeze fresh lemon juice over the fillets.
Add a few cracks of black pepper for extra aroma.
Garnish and serve: Top with chopped parsley or dill and serve with lemon wedges. Pair with your favorite side for a complete meal.
