Per portion: 802 kJ / 192 kcal

  • 2 tbsp olive oil
  • knob butter
  • 2 large red onions, thinly sliced
  • 2 tbsp soft light brown sugar
  • 500g good quality beef mince
  • 2 tbsp finely chopped fresh parsley
  • 2 tbsp finely chopped fresh thyme
  • 8 tbsp Kikkoman Teriyaki Sauce with Roasted Garlic
  • 1 small head radicchio, shredded
  • 4 brioche burger buns, halved and cut side toasted
  • 2 avocado’s, sliced


Preparation time: 40 mins

Heat 1 tbsp of the oil and the butter in a frying pan over a low heat. Add the sliced onions and the sugar and cook over a fairly low heat for about 30 minutes, stirring often, until the onions are soft and caramelised, season with a little salt and pepper. 

While the onions cook mix the mince with the parsley and thyme and season with salt and pepper. Form into 4 burgers. Once the onions are cooked remove from the pan and keep warm. Wipe out the pan with a piece of kitchen paper and heat the remaining oil. Cook the burgers for 3 – 4 minutes on each side then add the Kikkoman Teriyaki Sauce with Roasted Garlic and cook for a couple of minutes, basting with the sauce.

Place a handful of the shredded radicchio on the base of the burger buns, then add a burger, followed by a spoonful of the leftover sauce. Pile a quarter of the caramelised onions on top, then add the avocado slices before placing the lid of the burger bun on top.


Brush the burgers with oil, then cook for 3 – 4 minutes on each side (depending on how hot your BBQ is). Brush the burgers with the teriyaki sauce and cook on each side for another couple of minutes.
