Heat the oil over medium/high heat in a skillet before preparing the zucchini so it has enough time to heat up. 

Put the flours and seasonings on a plate (i used a rimmed paper plate) and mixed together. Put the milk in a wide bowl or tupperware dish. 

Dip a zucchini stick into the milk and then gently roll it in the flour mixture. Tap off any excess flour and put it in the oil for about 5-7 mins or until it starts to brown and turn crispy. Use tongs or a skimmer to retrieve them and put them on a paper towel lined plate. 

Dip in my amazing ranch dressing and enjoy!

To reheat, place in an air fryer for a couple mins to make them crispy again. Or you could put them in the oven.
