Caramelised red onion beef burger
Ingredients
Preparation
Step 1
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.
Step 2
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.
Step 3
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.
Step 4
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.
