Units Scale

for the chicken…

  • 2 large chicken breasts (around 200g each), sliced in half across the length so you have 2 flatter pieces (see note 1)
  • 300ml buttermilk (see note 2)
  • 100g plain/all-purpose flour
  • 100g cornflour/corn starch
  • 1 tbsp garlic powder
  • 2 tsp smoked paprika (see note 3)
  • 1 tsp salt
  • 1 tsp pepper
  • 500ml oil (vegetable or rapeseed/canola)

for the garlic mayo…

  • 4 tbsp mayo
  • 1 tbsp lemon juice
  • 1 clove garlic, minced

to serve…

  • 4 soft burger buns
  • lettuce
  • 4 cheese slices such as Emmental, Gruyere or Swiss (see note 4)
  • 4 thick slices of tomato
  • 1 red onion, skin removed and cut into rounds down the length.


  1. In a large bowl, pour the buttermilk over the chicken and turn the pieces to coat them. Place in the fridge for at least 30 minutes, or up to 1 day (see note 5)
  2. Mix the flour ingredients together and turn the pieces of chicken in the flour until they are fully covered.
  3. Add the oil to a deep frying pan over medium heat. You want the oil to be around 2cm/1/2″ deep. Bring the oil to 180C/350F, if you don’t have a kitchen thermometer then add a small piece of batter to the pan and if it fizzes gently then the temperature is about right.
  4. Gently fry the chicken for 10 minutes, until cooked through and golden brown on the outside. When making multiple burgers, work in batches so you don’t overcrowd the pan.
  5. Use heatproof tongs to transfer the chicken to a wire rack and place a piece of cheese over each. Leave for 5 minutes.
  6. While the chicken is resting, make the mayo by whisking together all the ingredients.
  7. Prepare the burgers by adding a couple of pieces of lettuce to the bottom bun and a slice of tomato. Place the chicken on top followed by the onion and the garlic mayo.


  1. If your chicken breasts are small then you can alternatively place them between two pieces of cling film and bash them with a rolling pin to flatten them out.
  2. If you can’t find any buttermilk then you can make your own by using 3 parts sour cream mixed with 1 part milk. Or you can use kefir instead.
  3. If you want a bit of a kick to the burger then use hot paprika or add some cayenne pepper.
  4. Choose any type of cheese that will melt easily when placed on the chicken.
  5. The buttermilk actually helps to tenderise the chicken, so leaving the chicken marinading in the buttermilk overnight helps you achieve a super tender and delicious burger.
