Part 3/5:
Coating the Onion
Once the onion has soaked, it’s time to prepare the batter. In a mixing bowl, combine the flour, black pepper, sweet paprika, and salt.
Next, in another bowl, whisk together the egg and milk until fully combined.
Once the onion has finished soaking, remove any excess flour and coat the onion with the egg and milk mixture. This coating will help the breadcrumbs stick better, ensuring a crunchier outcome.
Generously sprinkle breadcrumbs all over the onion, trying to get them into all the nooks and crannies for an even crunch. Once done, make sure to remove any excess breadcrumbs.
Spraying for Crispness
To achieve that perfectly crispy exterior without deep frying, spray the base of the air fryer and the onion with oil. This will aid in crisping while cooking.
