Remove any outer leaves of the brussels sprouts that don't look healthy. Lightly cook your brussels sprouts, either by boiling them for 13-15 minutes or by microwaving them on high for about 3-4 minutes.
Cut them in half.
Place all ingredients in a medium or large mixing bowl and toss to coat the brussels sprouts evenly.
Pour them into the food basket of the air fryer and close it up.
Set the heat to 390 F. and the time to 8 minutes. This setting roasts them nicely on the outside while leaving the insides a nicely cooked al dente.
Cool slightly and serve.
