Barbecued celeriac burger


This vegan burger recipe replaces the classic beef patty with a thick disc of barbecued celeriac, glazed in a homemade barbecue sauce until crisp, sweet and sticky. It's far better than any veggie burger you can buy in the shops, and once paired with your favourite vegan condiments and burger fillings, creates a fantastic dish to serve at any barbeuce.

The search for a decent vegan burger recipe can be quite an arduous one: crumbly textures, tasteless tofu, same old slimy portobello mushroom. This slow-roasted celeriac is cooked directly on the hot coals, giving it a wonderfully smoky flavour. It is then sliced into burgers and glazed with an umami-rich homemade vegan barbecue sauce – the secret ingredient is marmite!




Barbecued celeriac burger

Barbecue sauce

To serve

  • 4 bread buns
  • 1 tomato, sliced
  • gem lettuce, leaves washed
  • 1 red onion, sliced
  • gherkins
  • ketchup, vegan mayonnaise, mustard or any other burger condiments you like


Preheat the barbecue to 180°C
Peel the celeriac and rub with olive oil and wholegrain mustard. Wrap in tin foil then place directly onto the hot coals. Cook for 45–60 minutes, turning every 15 minutes to get a nice even cook. The celeriac should be cooked through but still hold its shape
While the celeriac is cooking, place all the barbecue sauce ingredients in a pan and gently heat for about 5–10 minutes, until it has thickened slightly
Unwrap the celeriac and scrape off any burnt bits. Slice into 4 nice thick burgers
Increase the heat of the barbecue to 220°C and set it up for direct cooking
Glaze the burgers with the barbecue sauce and grill on each side until crispy with bar marks. Brush with more barbecue glaze each time you flip
Serve immediately in a bread bun with your favourite burger condiments and fillings
