Instructions

Bash the Chicken
1

a) If you don't have a toaster, preheat your oven to 220°C/200°C fan/gas mark 7 for the burger buns.

b) Sandwich each chicken breast between two pieces of baking paper or cling film. 

c) Pop onto a board, then give it a bash with a rolling pin or the bottom of a saucepan until it’s 1-2 cm thick. Season with salt and pepper. IMPORTANT: Wash your hands and equipment after handling raw chicken and its packaging.

Oh Crumbs!
2

a) Crack the egg (see pantry for amount) into a medium bowl and whisk. 

b) Put the breadcrumbs into another bowl and season with salt (see pantry for amount) and pepper. 

c) Dip the chicken into the egg and then the breadcrumbs, ensuring it's completely coated.

d) Transfer to a clean plate. IMPORTANT: Discard any excess egg.

Into the Pan
3

a) Pop a large frying pan on high heat and add enough oil to completely coat the bottom of the pan. TIP: You want the oil to be hot so the chicken fries properly - heat for 2-3 mins before you add the chicken. 

b) Once hot, carefully lay the chicken into the pan, reduce the heat to medium-high and fry until golden brown and cooked through, 8-10 mins total.

c) Turn every 2-3 mins and adjust the heat if necessary. IMPORTANT: The chicken is cooked when no longer pink in the middle.

d) Once cooked, transfer the chicken to a plate lined with kitchen paper.

In a Pickle
4

a) Meanwhile, combine in a medium bowl half the rice vinegar with the sugar for the pickling (see pantry for amount).

b) Add the coleslaw mix and a pinch of salt to the rice vinegar bowl, then toss toss to coat. Set aside to pickle.

c) In a small bowl, combine the korma curry paste, mayonnaise and honey (see pantry for amount). Season with salt and pepper and mix well.

Finishing Touches
5

a) When the chicken is almost ready, halve the burger buns. 

b) If you're using the toaster, toast the burger buns in your toaster until golden. If you're using the oven, pop them into the oven to warm through, 2-3 mins.

c) In the meantime, combine in a large bowl the remaining vinegar with the sugar and olive oil for the dressing (see pantry for both amounts). Season with salt and pepper.

d) Add the baby leaves to the bowl and toss to coat. TIP: Don't add the leaves too early or they'll go soggy.

Assemble and Serve
6

a) Share the burger buns between 2 plates. Spread the katsu mayo over both the lid and base of the buns. 

b) Top the bun bases with the breaded chicken and pickled slaw mix. Sandwich shut with the bun lids. 

c) Serve the baby leaf salad on the side. Pop any remaining sauce in a small bowl alongside for dipping to finish.

Enjoy!

Review summary

Updated on Feb 2026
  • Flavour: The pickled vegetables elevate the burger when combined, creating a surprisingly good combination.
  • Ease of prep: While some found it easy to make, others noted it took longer than expected and required many bowls.
  • Suggestions: Consider slicing the chicken breast in half for better cooking and easier assembly with the salad.
  • Next-day meals: Enjoy the burger with homemade chips for a satisfying meal.
  • Sauce: The curry sauce might benefit from additional seasoning to round out the flavour.
