Pat salmon fillets completely dry with paper towels. Season all over with kosher salt and black pepper. Let sit at room temperature for 15 minutes.
In a small bowl, whisk together ketchup, brown sugar, apple cider vinegar, Worcestershire sauce, smoked paprika, garlic powder, and onion powder until smooth.
Preheat the air fryer to 400°F (200°C) for 3-5 minutes.
Brush the salmon fillets with avocado oil. Place them skin-side down in the preheated air fryer basket, ensuring they are not overcrowded. Cook for 5 minutes.
Pause the air fryer, pull out the basket, and brush a generous layer of the BBQ glaze over the top of each fillet.
Return the basket to the air fryer and cook for another 3-5 minutes, or until the internal temperature reaches 145°F and the glaze is bubbly.
Carefully remove the salmon from the air fryer and let it rest for 1-2 minutes before serving.
Notes
For best results, use an instant-read thermometer to ensure the salmon is cooked to a perfect 145°F and not a degree more.
