Make breading mixes: Add all ingredients for dry breading mix to a shallow dish and whisk to combine. Then place egg and buttermilk in a separate mixing bowl and whisk to combine.
Bread chicken: Toss chicken in dry mixture to thinly coat, then in egg mixture. Finally, dredge each chicken piece through dry mix again, this time thickly coating. Pound/press breading into chicken for it to stick (may seem floury and dry, but will cook perfectly with the butter added). You may not need all of the dry mix, but it's easier to bread if there is plenty.
Air fry: Place breaded chicken pieces in the hot air fryer basket (do not stack!). Top each piece with several slices of butter (using about 2 of the 3 tablespoons).Air fry at 400°F (200°C) until golden brown and crispy on top (8-10 minutes for thinner chicken breast, 10-12 minutes for thicker chicken breast, 12-14 minutes for chicken thighs, 6-8 minutes for chicken strips, 10 minutes for drumsticks).
Finish: Carefully flip chicken, dot with remaining butter and air fry at 400°F (200°C) for the same time as before again, until breading is golden and crispy and chicken reaches an internal temperature of at least 165°F (74°C).I flip for a final time and air fry for 1-2 minutes on the highest temperature my air fryer will go to for maximum crispiness. Serve immediately.

Ingredient notes
Chicken: You can make this recipe with chicken breast, thighs, drumsticks or tenders. I have seen a few recipes making them with different pieces, but I actually wouldn’t recommend it because they all have slightly different cooking times and make it more difficult to cook the chicken right. This really needs to be eaten as soon as it’s ready, so I prefer to use all of the same cut per batch I air fry.
Breadcrumbs: I used regular because Panko isn’t available all the time in my neck of the woods. Either works just fine – and you can even use Italian seasoned in a pinch if that’s all you have on hand.
Buttermilk: I prefer buttermilk over regular milk in this recipe, but if all you have is regular milk you can stir 1 tablespoon apple cider vinegar into the milk, leave it to sit on the counter for 10 minutes and then use it. I have made this recipe with regular milk before and while it's delicious, the breading tends to stick a little less well. A great option is to use 2 eggs in place of the buttermilk if you don't have any on hand. Just doesn’t have that little bit of tang from the buttermilk – I serve it with some lemon wedges to make up for it ?
Butter: Even though this is an air fryer recipe, you do still need fat to create a crispy, cooked coating. Without the butter, you’d be left with a very dry/floury coating. So please don’t skimp on this. It really isn’t that much butter per serving compared to deep fried chicken and you’ll regret it if you don’t use enough. I suppose you could spray the chicken with oil spray instead and it would be OK, but to be perfect I very strongly recommend the butter.
Baking powder: This may seem like an odd ingredient here, but together with the egg it adds some body to the breading and helps to puff it up and brown more.
Recipe tips
I recommend combining the dry breading ingredients before combining the wet ingredients. That way your whisk isn't wet when wanting to use it for the dry ingredients - and you don't need to wash/dry it in between OR use two utensils!
Make sure to pound the breading onto the chicken, else it may fall off. I either use the back of a large spoon or the back of my kitchen tongs for this. But if you’re breading by hand, you can also just use your flat hand to pound the breading on.
Evenly distribute the sliced butter over each piece to make sure some will melt everywhere. Otherwise you’ll be left with dry patches. You can check on your chicken after about 5 minutes and see if there are any dry patches of flour. Feel free to dab a little oil on there, or place another small pat of butter on the dry part.
Please do serve this right away. If you allow it to sit for a while, it will start to turn soggy. That’s perfectly normal because the chicken stays so juicy when cooked in the air fryer! It will start to release its juices once it’s cooked and then the breading will become affected after a while. So please, serve ASAP!
Recommended internal temperature for chicken
The US government’s food safety website recommends cooking all poultry to an internal temperature of at least 165°F (74°C) for safe consumption.
