In a medium bowl, whisk together the flour, milk, salt, and garlic powder. Allow for the mixture to sit for a couple minutes to thicken up.
Toss the florets in the flour-milk mixture until the florets are well coated.
Spray the trays or air fryer baskets with oil.
Spread the florets out on the trays of the air fryer in a single layer. Make sure not to overcrowd the florets so the air can circulate around them.
Air fry for 15 minutes. If you have two trays in your air fryer, you’ll want to switch them halfway through to they both get evenly cooked. If you have a basket with your air fryer, you may need to work in batches.
Transfer the air fried cauliflower to a large bowl with the BBQ sauce and toss until coated.
Plate the BBQ cauliflower and serve with fresh herbs like cilantro for garnish.
nutrition facts will depend a lot on what BBQ sauce you use 🙂
