  • 400 g tin black beans rinsed, drained and lightly mashed
  • 250 g portabellini mushrooms finely sliced
  • 1 large white onion diced
  • 500 g beef mince
  • 50 g panko breadcrumbs
  • 2 tbsp fresh parsley finely chopped

Homemade tomato sauce

  • 400 g tin tomato purée
  • 40 g brown sugar
  • 3 tbsp red wine vinegar
  • ½ tsp onion powder
  • 1 tsp celery salt

To serve

  • 12-15 white slider buns / mini burger buns many bakeries also call these cocktail buns
  • mayonnaise
  • lettuce leaves
  • tomato sliced
  • red onion sliced
  • salt and pepper
  • olive oil


To make the tomato sauce

  • Place all the ingredients in a saucepan over medium heat.
    Stir gently until everything comes to a light simmer.
  • Cover and reduce heat to low.
    Simmer for 15 minutes for the flavours to develop.
  • Taste to adjust seasoning.

For the patties

  • Preheat a braai to medium high heat.
  • Heat a drizzle of olive oil in a frying pan.
    Add the mushrooms and cook until golden brown.
    Add the onion and a pinch of salt.
  • Cook until tender, golden and lightly caramelised.
    Place in a large bowl.
  • To the bowl add the black beans, beef, breadcrumbs and parsley.
    Season well with salt and pepper.
    Mix thoroughly until very well combined.
  • Shape mixture into patties.
    It is a good idea to check the size of your slider buns and make your patties are just larger than the buns as they will shrink during cooking.
  • Brush patties all over with olive oil and braai until golden brown on both sides.
    You can also bake them in the oven or cook them on the stovetop.
  • Allow the patties to rest.
    Build sliders with your favourite burger toppings.
    Add a generous dollop of homemade tomato sauce to each slider and enjoy!
