1. Prep the Salmon: If starting with frozen salmon, ensure it’s fully thawed before cooking. The best way to thaw salmon for air fryer use is by leaving it in the refrigerator overnight. This slow thawing ensures the fish retains its texture and flavor.

2. Pat the salmon fillets dry with paper towels. This step is crucial for the seasoning to stick properly. Mix the BBQ rub with a tablespoon of olive oil in a small bowl. Then, brush this mixture evenly over all sides of the salmon fillets. The oil not only helps the rub to adhere but also promotes even cooking and browning.

3. Preheat the Air Fryer: Set your air fryer to 400°F (about 200°C). This cooking temperature is ideal for salmon, giving it a slightly crisp exterior with a tender, moist interior.

4. Arrange the Salmon: Place the salmon fillets in the air fryer basket. Make sure they are not touching; air flow is key to the air frying process. If your air fryer is small, cook the salmon in batches.

5. Cook the salmon for about 10 minutes, depending on their thickness. The cooking time for salmon in air fryer can vary, so it’s essential to check for doneness. The salmon should flake easily with a fork but still retain some firmness.

6. Check for Doneness: Insert a fork or a toothpick into the thickest part of the salmon. If it slides in easily and the flesh flakes, it’s done. If you have a cooking thermometer, the internal temperature should read 145°F (63°C).
