The best Korean Fried Chicken – crispy coated buttermilk fried chicken smothered in a spicy Korean-inspired gochujang sauce.
The sauce is so rich, flavourful and complex and it comes together very easily – just throw all the ingredients in a pan and bubble it up.
We love to eat this with rice, noodles, or my personal favourite – stuffed into bao buns!

One thing that I absolutely love as a recipe creator, is when I put a plate of food down in front of people, and the conversation stops the moment the first bite is taken. Just quiet, wide-eyed, satisfied munching, with the occasional ‘Mmmmm‘ and ‘oh my god, it’s so good‘ until it’s all gone.

That moment when everyone wants to focus all of their senses on what they’re eating, and nothing else matters.

That’s what happens with this Korean Fried Chicken Recipe.

I’m using my popular buttermilk chicken to start off this recipe. If you’ve never had it, you’ve got to give it a go (especially this Chicken burger version with honey mustard coleslaw). As someone who worked in fried chicken shops during school, college and university, I can confidently say I know my stuff when it comes to fried chicken.

What is gochujang?

Gochujang is a Korean fermented red chilli sauce or paste with a smoky-sweet and slightly spicy flavour. Some brands are spicier than others. I’ve prefer the paste, rather than the sauce for a stronger flavour. It’s a fantastic addition to sauces and marinades, as it adds heat, richness, tang and a little sweetness. I use it in lots of recipes (beef bulgogi, Pork ramen, Korean steak grilled cheese, sticky Asian ribs to name a few).


How to make it

  1. First we marinade the chicken in buttermilk, salt, white pepper and garlic salt.
  2. Then we coat the chicken in my special secret mixture. Only joking, it’s not secret. Find the full mixture in the recipe card below.

  • The spicy gochujang sauce is made using a mixture of gochujang paste (<– affiliate link), honey, brown sugar, soy sauce, garlic and ginger that’s been bubbled together until sticky and syrupy.
  • Then we fry the chicken until golden and crispy.
  • Pour the mixture over the crispy chicken and top with sesame seeds, spring onions and a few red pepper flakes.

Top Tips for Success

Ensuring the coating doesn’t fall off the cooked chicken:

When the chicken comes out of the oil, the coating will be securely adhered to the chicken. However, the longer you leave it before adding the sauce, the more careful you will have to be when tossing with the sauce to ensure the coating stays fully on.

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.

Can I bake the chicken rather than fry it?

If you want baked chicken, then follow the recipe for my baked chicken tenders, and mix with the gochujang sauce.

Instructions 

  • 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 overnight)
    4 chicken breasts, 240 ml (1 cup) buttermilk, 1/2 tsp salt, 1/4 tsp white pepper, 1/4 tsp garlic salt
  • Preheat the oven to a low heat (to keep the 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 cups) of oil.
    vegetable oil for deep frying
  • Mix together the crispy coating ingredients in a small bowl.
    180 g (1 1/2 cups) plain (all-purpose) flour, 1 tsp salt, 1 tsp ground black pepper, 1/2 tsp garlic salt, ½ tsp celery salt, 1 tsp dried thyme, 1 tsp paprika, 1 tsp baking powder, 1 tsp chilli flakes
  • 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.
    2 tbsp gochujang paste, 2 tbsp honey, 4 tbsp brown sugar, 4 tbsp soy sauce, 2 cloves garlic, 2 tsp minced ginger, 1 tbsp vegetable oil, 1 tbsp sesame oil
  • 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.

Notes

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.

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 1/2 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).

    Have you made this in an air fryer? Success? Thanks!

    I’ve made these wings about half a dozen times now and this recipe is fantastic. It’s got zing, savour and crunch, especially if you ONLY use corn flour for the pre-fry dusting. I’m also more generous with the sesame oil and seeds.
    Don’t sweat having to buy some ingredients that you don’t think you’ll use again. If you taste these wings, you’ll make them again and again!

  3. Geraldine says:

    Hi Nicky,

    May I know how to do the buttermilk?
    Thank you.

    1. Nicky Corbishley says:

      Hi Geraldine, you can replace the buttermilk with regular milk that’s been mixed with a tablespoon of lemon juice. Just stir it, then let it sit for 5 minutes before using.

    Absolutely phenomenal, Nicky! Whole family and I loved this and devoured this for dinner tonight. I would double the sauce next time, since I only had enough to cover half the chicken. Thank you!

    Please can you tell me how you make your buttermilk or where to purchase it from.
    Thanks

    This recipe takes a bit of time to make but it’s worth it. The chicken is crispy and flavourful, even by itself and the spicy glaze is just delicious.

  10. Malathi says:

    Hi i don’t have a refrigerator. So how can I store this chicken for 2 days?

    1. Nicky Corbishley says:

      Sorry, I can’t help on this one. I’d only ever store in a refrigerator for safety reasons.
