Method

  1. 1

    Make your homemade chili powder by lightly toasting the dried chillies in a dry frying pan over a medium heat for 1–2 minutes until fragrant. Remove stems and seeds, then grind the toasted chillies together with ground cumin, coriander, and smoked paprika using a spice grinder. Set aside.

    ~5 mins

    Tip: Toasting the chillies before grinding intensifies their flavour significantly

  2. 2

    Heat the olive oil in a large frying pan over a medium heat. Add the diced onions, garlic, celery, and carrots. Sauté for 5–7 minutes, stirring occasionally, until the vegetables are softened and fragrant.

    ~7 mins

    Tip: This forms the aromatic base of your chili

  3. 3

    Add your homemade chili powder blend to the sautéed vegetables and stir continuously for 1–2 minutes to bloom the spices and release their essential oils.

    ~2 mins

    Tip: Blooming spices in fat develops deeper, more complex flavour

  4. 4

    Deglaze the pan by adding a splash of vegetable stock and scraping up any browned bits from the bottom of the pan with a wooden spoon.

    ~2 mins

    Tip: These browned bits are packed with flavour

  5. 5

    Transfer the sautéed vegetables and spices to your slow cooker. Add the crushed tomatoes, drained kidney beans, drained black beans, and the remaining vegetable stock.

    ~3 mins

    Tip: Make sure all ingredients are well combined

  6. 6

    Season with sea salt and black pepper. Stir well to combine all ingredients.

    ~2 mins

    Tip: You can adjust seasoning further at the end

  7. 7

    Cover and cook on Low for 6 hours or on High for 3.5 hours. The chili should be bubbling gently at the edges and the flavours well developed.

    ~6 hrs

    Tip: Low setting develops flavour most beautifully, but High works if you're short on time

  8. 8

    Taste the finished chili and adjust seasoning as needed. Stir in fresh coriander if using.

    ~5 mins

    Tip: Add fresh herbs only just before serving to preserve their brightness

  9. 9

    Serve hot with lime wedges on the side and any additional toppings you enjoy.

    ~5 mins

    Tip: Popular toppings include sliced spring onions, diced avocado, or vegan soured cream
