Cut the cauliflowers into 1 to 2 inches florets

Combine the cornstarch, garlic powder, onion powder, salt, paprika, and water in a bowl and whisk until homogenous.

Add the batter to the cauliflowers and stir with clean hands until the cauliflowers are well coated with the batter.

Place the breadcrumbs into a plate and place the cauliflowers into it (a few pieces at a time) to coat them with the breadcrumbs.

Place the cauliflowers into the air fryer basket and fry during 15 minutes at 370 degrees. Then stir, and fry the cauliflowers 7 more minutes.

Let it cool a few minutes, and eat while crispy and warm.
