Adzuki bean burgers are juicy, healthy vegetarian patties made with canned beans. Burgers with adzuki beans and no breadcrumbs have a great flavour and texture, and they hold together well.
Place the frying pan on a medium heat and add the olive oil. Saute the onions for 5 minutes, then add the garlic and saute for a further 5 minutes. The onions should be golden brown.
Tip the cooked onions into a bowl and add the drained adzuki beans, ground oats, eggs, seasoning, mustard powder and Worcestershire sauce. Either mash together with a fork or lightly blitz with an immersion blender. Don't over-blend the mixture as it should have some texture.
Divide the mixture into 4 portions and shape into patties with your hands.
At this point, the burgers can be refrigerated. They are easier to handle when chilled, but if you don't have time it's not essential.
Heat a frying pan over a medium heat and add the remaining olive oil. Fry the burgers for about 5 minutes on each side until lightly browned.
If you want BBQ'd bean burgers, brush the patties with olive oil before placing on the grill.
Notes
Either use instant oats or grind the oats in a food processor
Add some spice if you like. Ground spices can be added to the sauteed onions
Make sure that the adzuki beans are well drained so that you don't add extra liquid to the recipe
For spicy veggie bean burgers, add your chosen ground spices (cumin and chilli both go well) to the caramelized onions.
If you want to make vegan adzuki bean burgers, then use flax eggs instead. Mix 2 tablespoons of flaxseed with 5 tablespoons of water. Leave it aside for 10 minutes then use in the mixture in place of the eggs.
