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

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.

TO BBQ

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.
