To do this, whisk together the mayo, soy milk, parsley, dill, garlic powder. Then, add a pinch of salt and season to taste, if needed. Set aside.
Next, heat the milk and cornstarch together in a medium saucepan until cornstarch has dissolved. Then, heat the milk over medium heat until slightly thickened, about 4-5 minutes, then set aside to let cool.
Then, whisk together the flour, garlic salt, paprika, onion powder, black pepper, and salt in a large bowl.
After that, dip the cauliflower into the flour, then into the thickened milk mixture, then back into the flour. Then, tap off as much of the excess flour as you can, then place in a single layer in the bottom of your Air Fryer. Repeat with the rest of the cauliflower; knowing that you may have to work in two batches depending on the size of your Air Fryer.
Then, place the air fryer tray into the Air Fryer and set to 7 minutes at 400 degrees F. Let cook, then flip/shake ~halfway through cooking.
Next, heat the butter, buffalo hot sauce and vinegar over medium heat. Finally, toss with the crispy cauliflower and serve immediately with the ranch dressing.
