Preheat air fryer at 400 F degrees. To a large bowl, add cauliflower florets.
In another small bowl combine melted butter and red hot sauce; stir. Pour over cauliflower and using tongs stir very well to coat.
In another small bowl, add flour, cornstarch, garlic powder, paprika and salt; stir well to mix. Sprinkle 1/4th of it over the cauliflower and using tongs stir well to coat. Repeat with remaining flour mixture adding it in small increments until it runs out.
Spray air fryer basket with cooking spray well and transfer cauliflower into it in a single layer. You will have to cook it in a few batches, depending on the size of your air fryer. Air fry for 12 minutes at 400 degrees F.
While buffalo cauliflower is roasting, prepare blue cheese dipping sauce. Serve immediately with celery and carrot sticks, if you wish.
Notes
Store: Refrigerate in an airtight container for up to 4 days.
Reheat: Reheat in air fryer at 400 degrees F for 3-4 minutes or until warm.
Work in batches. You want an even single layer spread out in the basket, but also leaving enough room for the air to circulate and the heat to evenly distribute throughout. If not, you'll end up with soggy cauliflower.
My air fryer size: I use a large 5.8 quart Cosori air fryer. If yours is smaller, fit as many ingredients as you can, as long as they are in a single layer.
For an extra bit of crunch: Transfer the cauliflower to a lined baking sheet and place them under the broiler for a couple of minutes.
