Big Bhaji Burger

This vibrant vegan onion bhaji burger is a spectacular fusion of classic Indian street food and a hearty British takeaway favourite. The bhajis are expertly spiced with garam masala, fresh ginger, and toasted seeds, creating a satisfyingly crisp patty that rivals any traditional beef burger. Deep-frying the bhajis until they are golden brown ensures a wonderful crunch that contrasts beautifully with the soft, toasted bun and creamy avocado.

Perfect for a weekend treat or a creative meat-free Monday dinner, this dish is packed with fresh flavours and contrasting textures. The addition of sweet mango chutney and crushed poppadoms provides a salty, tangy finish that elevates the burger to something truly special. Serve these immediately while the bhajis are hot and the toppings are fresh for the ultimate homemade experience.

Ingredients for Big Bhaji Burger

  • 475 to 950ml vegetable oil, for deep-frying

  • 2 red onions

  • 1 (2 1/2-inch) piece fresh ginger

  • 1 fresh red chilli

  • Generous 1 cup fresh coriander leaves

  • 1 1/2 teaspoons coriander seeds

  • 1 1/2 teaspoons cumin seeds

  • 325g chickpea flour

  • 1 1/2 teaspoons garam masala

  • Generous 180ml water

  • 4 good-quality burger buns

  • 45ml vegan mayonnaise, to serve

  • 1/4 small cucumber, to serve

  • 1 large tomato, to serve

  • 1 avocado, to serve

  • 1 little gem lettuce, to serve

  • 2 tablespoons mango chutney, to serve

  • 1 pappadum, to serve

  • Salt

  • Large saucepan over high heat | Cooking thermometer, optional | Pestle and mortar | Line a dinner plate with paper towels

Pour the vegetable oil into the large saucepan so that it comes no more than two-thirds up the side of the pan | Heat the oil to 177°C, or until a wooden spoon dipped into the oil sizzles around the edges

Meanwhile, peel and very finely slice the onions and put them into a big bowl | Peel the ginger by scraping off the skin with a spoon and finely chop | Rip the stem from the chilli, cut it in half lengthwise, and remove the seeds if you prefer a milder flavour, then finely chop and add to the pan | Roughly chop the coriander leaves | Add the ginger, chilli, and coriander to the bowl | Crush the coriander seeds and cumin seeds with a pestle and mortar or the end of a rolling pin and add them to the bowl | Add the chickpea flour, garam masala, water, and a generous pinch of salt and mix until everything is well combined and covered with a wet sticky batter

Divide the mixture into 6 and use your hands to mold it into patties around 3 1/2 inches wide and no more than 1/3 inch thick | Use a metal spoon to carefully lower 2 of the patties into the hot oil and cook them for about 5 minutes, flipping them over halfway | Remove the patties when they are golden and crisp and transfer to the plate lined with paper towels to drain any excess oil | Repeat with the remaining patties

While the bhajis are frying, split the burger buns open and spread the bottom halves with vegan mayonnaise | Thinly slice the cucumber and tomato | Halve and carefully pit the avocado by tapping the pit firmly with the heel of a knife so that it lodges in the pit, then twist and remove the pit | Run a spoon around the inside of the avocado skin to scoop out the flesh, then slice finely

To serve the bhaji burgers, lay a few lettuce leaves on the bottom of the burger buns and place the burgers on top | Spread a little mango chutney on top of each, followed by slices of tomato, avocado, and cucumber | Break up the pappadum and sprinkle it over the top before closing the buns
