Roasted Aubergine Soup with Harissa and Crispy Chickpeas

Deeply roasted aubergines are blended into a velvety, smoky soup with a good hit of harissa and a base of sweet red peppers and onions. The contrast of the smooth soup and the crunchy spiced chickpeas on top is what makes this dish — do not skip them. This is the kind of soup that warms you from the inside out and genuinely satisfies as a main course.

Ingredients

  • 900 Aubergines, cut into large chunks, roughly 4cm
  • 2 Red peppers, deseeded and roughly chopped
  • 2 Red onions, roughly chopped
  • 5 Garlic cloves, unpeeled
  • 4 tbsp Olive oil
  • 2 tbsp Harissa pasterose harissa works beautifully here
  • 900 ml Vegetable stock, hot
  • 1 tsp Ground cumin
  • 1 tsp Smoked paprika
  • 400 g Tinned chickpeas, drained, rinsed, and thoroughly dried with kitchen paper
  • 2 tbsp Neutral cooking oil
  • 1 tsp Ground coriander
  • 2 tsp Sea salt
  • 1 tsp Black pepper, freshly ground
  • 1 Lemon, juiced
  • 15 g Fresh coriander, roughly chopped (optional)

Method

  1. Preheat the oven to 200°C fan (220°C conventional). Spread the aubergine chunks, red peppers, red onions, and unpeeled garlic cloves across two large roasting trays. Drizzle with the olive oil, scatter over the cumin, smoked paprika, 1 tsp salt, and the black pepper. Toss everything together well, then spread into a single layer. Roast for 35–40 minutes, turning once halfway through, until everything is well roasted, caramelised, and slightly charred at the edges.About 40 min
  2. While the vegetables roast, prepare the crispy chickpeas. Make sure the chickpeas are completely dry — spread them on a clean tea towel and rub them firmly to remove excess moisture and any loose skins. Toss with the neutral oil, ground coriander, remaining 1 tsp salt, and a pinch of smoked paprika. Spread on a separate baking tray and put in the oven alongside the vegetables for the final 20 minutes of roasting, until deeply golden and crisp.About 20 min
  3. Once the vegetables are done, squeeze the roasted garlic cloves out of their skins directly into a large saucepan. Add all the roasted aubergine, peppers, and onions, scraping in any caramelised juices from the roasting tray. Add the harissa paste and pour over the hot stock.
  4. Use a stick blender to blitz the soup until completely smooth. Alternatively, carefully ladle into a jug blender in batches and blend until silky. Return the soup to a medium heat and simmer for 5 minutes. Add the lemon juice and taste, adjusting the seasoning and adding more harissa if you want more heat.About 5 min
  5. Ladle the soup into warmed bowls. Top each serving with a generous handful of the crispy chickpeas and scatter over the fresh coriander if using. Serve immediately — the chickpeas lose their crunch quickly once they hit the hot soup, so get them on at the last moment.

Tips

  • Drying the chickpeas thoroughly is the difference between crispy and chewy — it is worth spending a full minute rubbing them in a tea towel. Any moisture on the surface will steam rather than roast them.
  • The depth of colour you get on the roasted vegetables is the foundation of the soup's flavour. Push past the point where you might normally take them out — you want real caramelisation, not just softening.
  • If the soup is thicker than you like after blending, loosen it with a splash more stock or water and check the seasoning again.

Ring the changes

  • Swirl a tablespoon of tahini into each bowl just before serving for a creamier, nuttier result — note this adds sesame allergen.
  • Stir 200ml of coconut milk into the soup in step 4 instead of some of the stock for a slightly richer, more rounded version.

Keeping it

The soup keeps well in the fridge for up to 4 days and freezes brilliantly for up to 3 months. Store the crispy chickpeas separately in an airtight container at room temperature for up to 2 days — re-crisp in a hot oven for 5 minutes before serving. Do not freeze the chickpeas.

Miso-Glazed Aubergine Steaks with Sesame Soba Noodles

Thick aubergine steaks caramelise under a high grill with a sweet miso glaze until they are sticky, tender and almost meaty in the centre. They sit on a bed of cool sesame-dressed soba noodles, making this a dish that works just as well at room temperature as hot. It is bold enough to convert anyone who thinks aubergine needs to be hidden in something else.

Turkish Aubergine and Tomato Bake (İmam Bayıldı)

Whole aubergines are split and stuffed with a sweet, slow-cooked mixture of onions, tomatoes, and garlic, then baked in olive oil until completely tender and collapsing. This is the classic Turkish dish whose name translates as 'the imam fainted' — allegedly from the sheer quantity of olive oil used. Serve warm or at room temperature with crusty bread and a dollop of yoghurt.

Spiced Aubergine and Chickpea Stew

A deeply warming Middle Eastern-style stew that comes together in well under an hour, built on big cubes of aubergine that slowly melt into a spiced tomato broth alongside tender chickpeas. The aubergine practically disappears into the sauce, giving it a silky, almost meaty body that makes the whole thing taste like it has been cooking all day. Serve with flatbreads or over rice.
