Smoky black bean burgers with avocado and salsa

Proper chunky bean burgers with a crisp crust and a smoky middle, piled into buns with smashed avocado. Drying the beans in the oven first is what stops them going mushy.

Ingredients

Method

  1. Heat the oven to 200°C (180°C fan). Pat the drained beans dry with kitchen paper, spread them on a baking tray and bake until the skins start to split and look dry.
  2. Meanwhile, fry the onion in a splash of the oil for 5 minutes until soft, then stir in the garlic, smoked paprika and cumin for a minute. Tip the beans into a bowl and mash roughly, leaving some whole. Mix in the onion, tomato purée, breadcrumbs, flour and salt.
  3. With damp hands, shape the mix into 4 thick patties (or 6 smaller ones for children). Chill them so they firm up.
  4. Boil the corn in a big pan of water until tender, then drain.
  5. Heat the rest of the oil in a large frying pan over a medium heat. Fry the burgers for 4–5 minutes each side, turning carefully once, until they have a dark, crisp crust.
  6. Toast the buns. Mash the avocados with the lime juice and a pinch of salt. Spread avocado on the bases, add lettuce and a burger, spoon over salsa and serve with the corn.
