These black bean burgers are by far some of my favourite homemade burgers to make. It has a satisfying and robustly meaty texture, with the creaminess from the Sriracha garlic aioli and the sweetness of the caramelised onion. It is so good that even devout carnivores will love it. Serve the burgers with some crispy baked potato chips and more garlic aioli and enjoy!!!

Black Bean Burgers with Caramelised Balsamic Onion

Black Bean Burgers with Caramelised Balsamic Onion Prep time: 20 mins Cook time: 40 mins Serves: 5-6


  • 4 sourdough burger buns (or wholemeal burger buns)
  • 1 tablespoon of butter
  • 2 cups of cooked black turtle beans*, roughly mashed
  • 1 red onion, finely chopped
  • 1 cup finely chopped flat leaf parsley
  • ½ cup of almond meal or flour
  • 1 carrot, grated (squeeze out any excess water)
  • 1 egg
  • 1 teaspoon salt
  • 1 teaspoon pepper
  • 2 white onions, finely sliced
  • 2 tablespoons of balsamic vinegar
  • 1 tablespoon coconut sugar
  • 3 tablespoons extra virgin olive oil
  • 1 tablespoon Sriracha chilli sauce
  • 3 tablespoons garlic aioli
  • 1 tablespoon lemon juice
  • 2 tomatoes, sliced
  • 8 green leaf lettuce leaves


  1. 1 Black Bean Patties: Mix mashed black turtle beans, chopped red onion, parsley, almond meal, carrot, egg, salt, and pepper. Scrunch the bean mixtures well with clean hands. Divide into 4-5 balls (depends on the size you prefer), flatten into patties, and place into the fridge to chill for 15 minutes.
  2. 2 Caramelised Balsamic Onion: Heat 2 tablespoons of olive oil in a pan over medium heat. Add the sliced onion with a pinch of salt into the pan and cook very slowly for 15-20 minutes until soft and golden, stirring them occasionally. Add coconut sugar and balsamic vinegar when the onions are soft, and this will start the caramelisation process. Cook for another 5 minutes on low heat until sticky and caramelized and add some cracked pepper at the end. Place the cooked onion in a bowl and set aside.
  3. 3 Sriracha Garlic Aioli: Mix through the Sriracha sauce, garlic aioli and lemon in a bowl and set aside.
  4. 4 Heat 1 tablespoon of olive oil in a non-stick pan over medium heat.
  5. 5 When the pan is hot, fry the patties for about 3-4 minutes on medium heat on each side, until golden brown. Reduce the heat if they colour too quickly.
  6. 6 Place the patties onto a plate once they are cooked and leave them aside.
  7. 7 Halve the burger buns and spread them with butter to add more flavour.
  8. 8 Throw the buns onto a pan over high heat and grill them until toasted, about 1-2 minutes per side.
  9. 9 To assemble the burger, place 2 pieces of green leaf lettuce on each bun base, a burger patty, a tablespoon of siracha garlic aioli, 2-3 slices of tomatoes, and top with caramelised balsamic onion and the bun lid.
  10. 10 Serve immediately and enjoy!


* I usually use uncooked black turtle beans, soak them overnight, and then boil them in water for half an hour or until soft. However, you can also use beans from cans. You can also substitute black turtle beans with kidney beans, black-eyed beans, or even beef mince for a non-vegetarian version.
