Spray your chicken breasts with spray oil.
Sprinkle over smoked paprika, garlic salt and season well with salt and pepper too. Alternatively you can mix it all together beforehand and sprinkle on.
Turn over and repeat this step again.
Lay the chicken in the air fryer basket.
Cook at 180C (360F approx) for 10 minutes.
Turn over the chicken breast.
Air fry at 180C (360F approx) for another 8 minutes.
Pour over the barbecue sauce; I like to use a silicone pastry brush to ensure even coverage, but you can just use a spoon or whatever you have to hand.
Air fry at 180C (360F approx) for another 2 minutes.
Check the internal temperature of the chicken breast (in the thickest part) is a minimum of 74C (165F) and then remove.
You can rest for 5 minutes before you slice and serve. Or just serve up as a whole chicken breast alongside the rest of your dinner.
