Prepare the Marinade: In a mixing bowl, combine the olive oil, garlic powder, paprika, oregano, salt, black pepper, and lemon juice. Mix well.
Marinate the Salmon: Place the salmon fillets in the bowl and coat them evenly with the marinade. Let them sit for about 10 minutes to absorb the flavors.
Preheat the Air Fryer: Preheat your air fryer to 400°F (200°C) for about 5 minutes.
Cook the Salmon: Place the marinated salmon fillets in the air fryer basket, skin side down. Cook for 10-12 minutes, or until the salmon flakes easily with a fork and has a crispy exterior.
Serve: Carefully remove the salmon from the air fryer. Garnish with fresh herbs and a slice of lemon if desired. Serve hot with your choice of sides.
