Cut 350 g Chicken breast into small, bite-sized pieces (about the size of a dice).
Combine 2 tablespoon Plain flour and 1 pinch Sea salt and ground black pepper on one plate.
Combine 50 g Panko breadcrumbs, 1 teaspoon Garlic powder, 1 teaspoon Onion powder and 0.5 teaspoon Paprika on another plate. Whisk 1 Egg in a bowl.
Coat the chicken in the flour, then dip into the whisked egg, then coat in the breadcrumb mix.
Repeat until all the chicken pieces are breaded.
Put into the air fryer basket in a single layer and spray with a little olive oil.
Cook at 200°C/400°F for 5 minutes, shaking halfway through cooking. You may have to cook in batches, depending on the size of your air fryer.
Notes
When breading the popcorn chicken, use one hand for putting the chicken in the flour and then putting it in and out of the egg mixture and then another hand for tossing it in breadcrumbs. This is to make sure the breadcrumb hand doesn't get covered in egg and clumps of breadcrumbs. You can also use tongs to prevent messy fingers.
If you are cooking air fryer popcorn chicken from frozen, don't thaw the chicken first, just cook from frozen.
Every air fryer varies, so the first time you make this in your air fryer, check the popcorn chicken after 4 minutes and adjust the cooking time as needed.
Don't overcrowd the air fryer basket. They need to be in one layer, without touching. This is so the air can circulate and they can get nice and crispy.
Shake the basket half way through.
Make sure the chicken is cut to the same size pieces, so that it cooked evenly.
You could add Parmesan cheese to the breadcrumbs for extra crispiness and cheesy flavour.
You can cook these in the oven instead. They will take about 12 minutes and will need flipping half way through.
