Start by chopping the onions in thick slices, about 4-5 slices per onion. Then separate each ring(the internal layers of the onion) by pressing from the centre, leaving 2 of them together if they’re too thin. This will assure a soft onion ring when cooked.
Prepare the chickpea egg by mixing the chickpea flour with water, and 2 tbsp of cornstarch. Then add smoked paprika, nutritional yeast, salt and garlic powder. Whisk well to avoid clumps. This should result in a thick batter, if it is not the case you could always add more cornstarch to thicken.
Place ½ cup of cornstarch in a small bowl, this is going to be the first step for the onion rings. Take one ring and coat it with cornstarch, shake it to throw away the excess.
Then place it in the chickpea egg. Make sure to perfectly coat it.
Finally, dip in the Panko.
Place each ring in the Air Fryer basket without overlapping, you may need to cook them in batches.
Cook them in the AirFryer at 400 F for 8-10 minutes.
