Happy Birthday BOSH!: The Big BOSH! Burger

This month BOSH! turns five years old, so we’re celebrating by sharing one of our favourite BOSH! recipes ever!

Over the years, BOSH! have shared over 14 burger recipes, and the hungry public recently voted the Healthy Black Bean Burger as their favourite! But in close second was this Big BOSH! Burger, which we all have a soft spot for here at HQ. You can find the recipe in BOSH!, the first BOSH! cookbook we ever published, and we love it just as much now as we did back then.

Check out the recipe below!


400g sweet potatoes
1 onion
olive oil
250g pre-cooked brown rice
20g breadcrumbs
½ tsp salt
½ tsp black pepper
½ tsp ground cumin
½ tsp garlic powder
½ tsp smoked paprika
2 tbsp plain flour
1 x 400g tin black beans


1 beef tomato
1 gem lettuce
1 large red onion
6 burger buns
6 tsp tomato ketchup
6 tsp vegan mayonnaise
12 slices gherkin


Preheat oven to 200°C | Line a baking tray | Large frying pan on a medium heat | Food processor

Peel the sweet potatoes and cut them into 2cm cubes | Put them on the lined baking tray and bake for 30 minutes | Take them out of the oven and set aside

Meanwhile, peel and mince the onion | Pour a little oil into the frying pan | Put the onion in the pan and fry for 10–15 minutes, until very soft |Transfer the onion to a large bowl and wipe out the pan

Put the baked sweet potato in the food processor | Add the rice, breadcrumbs, salt, pepper, cumin, garlic powder, smoked paprika and flour | Drain the black beans and add them to the food processor, then whizz everything up to a thick paste | Scrape the paste into the bowl with the onions and mix everything together with a spoon

Add a little oil to the pan and put it on a medium-high heat | Divide the mixture into six and use your hands to mould them into patty shapes | Place the patties in the hot pan and fry for 3 minutes on each side, until golden

While the burgers are cooking, slice the beef tomato into 6 thin slices | Separate the leaves of the lettuce and peel and slice the onion into thin rings

Build your burgers by placing them inside the burger buns, topping with ketchup, vegan mayo and slices of tomato and gherkin, lettuce and red onion

Yum! We can’t wait until dinner time. Will you be giving this recipe a go?
