In a small bowl, whisk together the smoked paprika, garlic powder, onion powder, dried thyme, cayenne pepper, black pepper, and salt to create the Cajun spice blend.
Pat the salmon fillets completely dry with a paper towel. Rub them all over with the avocado oil.
Sprinkle the Cajun spice blend generously and evenly over the top and sides of each salmon fillet.
Preheat your air fryer to 400°F (200°C) for 3-5 minutes.
Place the seasoned salmon fillets in the air fryer basket in a single layer, ensuring they do not overlap.
Cook for 8-10 minutes, until the salmon flakes easily with a fork or an instant-read thermometer inserted into the thickest part reads 135-140°F.
Carefully remove the salmon from the basket and let it rest for 1-2 minutes before serving.
Notes
The exact cooking time will vary based on the thickness of your salmon fillets and your specific air fryer model. Use an instant-read thermometer for best results.
