Place the chicken in a bowl. Add the buttermilk, salt, pepper and garlic salt. Mix together, cover and place in the fridge to marinade for at least 1 hour (up to over night)
Preheat the oven to a low heat (to keep cooked chicken warm). Heat a large pan of vegetable oil (or preheat your deep fat fryer) until hot (you can test by dropping a small cube of bread in there, if it rises immediately to the top and starts to bubble rapidly, it’s hot enough). You’ll need at least 1 litre (4 cup) of oil.
Mix together the crispy coating ingredients in a small bowl.
Take the chicken out of the fridge. Lift a piece from the buttermilk and allow the excess to drip off. Dredge the chicken in the crispy coating mixture – ensuring it’s fully covered. Place on a tray and repeat until all of the chicken is coated.
Once the oil is hot enough, add in 5 or 6 of the chicken tenders. You can add more or less depending on the size of your pan, just be sure not to overcrowd the chicken.
Cook for 3-5 minutes until golden brown and cooked in the middle. You can check this by cutting open a piece of chicken, if it’s no longer pink in the middle, it’s cooked.
Place on a tray in the oven to keep warm whilst you cook the rest of the chicken. **If you want to ensure the chicken stays extra crispy whilst in the oven, see my 'Top Tips for Success' section in the post.
Meanwhile make the sauce. Place the gochujang, honey, sugar, soy sauce, garlic, ginger, vegetable oil and sesame oil in a saucepan and stir together.
Bring to the boil, then simmer for 5 minutes until thickened.
Pour over the crispy chicken and carefully toss together, then top with the spring onions, chilli flakes and sesame seeds before serving.
Can I scale up or scale down the recipe?Yes you can halve or double the recipe using the same ingredient ratios. If doubling the recipe, please note it will take longer to fry the chicken as you'll have more batches to fry.How do you reheat Korean fried chicken?I prefer this Korean fried chicken served right away, as that's when the chicken will be at it's crispiest. However, you can cool, cover and refrigerate the Korean fried chicken (for up to a day), then reheat in the oven (covered) for 10-15 minutes at 190C/380F, until piping hot throughout.If you want to keep the chicken crispy, then fully cook both the crispy chicken and sauce, then cool and cover (keep the sauce separate from the chicken) and refrigerate for up to a day. Then reheat the chicken in the oven, uncovered, for 10-15 minutes at 190C/380F, until piping hot throughout. Reheat the sauce in a pan until piping hot.Nutritional Information is per serving.This info is approximate, as all of the flour may not be used up in coating the chicken (I've counted all of the flour as part of the nutritional info though). Also, I've included 1 ½ tbsp of oil per serving to account for the oil that is absorbed during deep frying (this is an *approximate* amount, the chicken may absorb more or less).
