Preheat your air fryer to 400 degrees F (200°C). This ensures that the salmon cooks evenly and gets that delicious, crispy exterior.
While the air fryer is heating, pat the salmon fillets dry with paper towels. This is important for getting a nice sear on the salmon.
In a small bowl, mix the olive oil, lemon juice, garlic powder, salt, and pepper. Brush this mixture over both sides of the salmon fillets, ensuring they are well coated.
Place the salmon fillets, skin-side down, in the air fryer basket. Cook for 7-10 minutes until the salmon is cooked and flakes quickly with a fork. The exact cooking time will depend on the thickness of your fillets.
When done, the salmon should reach an internal temperature of 145°F (63°C). Use a meat thermometer to ensure it's perfectly cooked.
Remove the salmon from the air fryer and rest for a few minutes. Garnish with fresh dill before serving. For an extra burst of citrus, serve additional lemon wedges on the side.
