Al's pitch is the fastest family Rogan Josh on the hob, 30 minutes start to finish using chicken breast instead of lamb. The slow cooker version preserves the entire hob spice build (which is where the colour and depth come from), then takes the chicken slow and gentle so the breast doesn't dry. Whole spices in oil, onions softened, ginger-garlic, then 900 g of vine-ripened tomatoes cooked down and mashed. Mixed powder, Kashmiri chilli, cumin, tandoori masala, ground coriander, black pepper, methi and tomato paste all bloom in the rogan-red gravy. Tip into the slow cooker, add chicken breast and 100 ml hot water, 2 hours low. Cherry tomatoes, coriander, salt, yoghurt and a teaspoon of sugar finish. Tastes even better next day.

Slow cooker notes: Al's hob version is built around a 30-minute time pressure with chicken breast added in the last 10 minutes. The slow cooker version preserves the entire hob spice build (whole spice oil bloom, onion soften, ginger-garlic, tomato cook-down and mash, ground spice bhuna) and replaces the 10-minute hob simmer with 2 hours low, gentler heat means juicier breast meat. Cherry tomatoes go in at the end so they keep their shape and pop in the bite. Yoghurt finishes the gravy and a teaspoon of sugar tames the tomato acidity.

Method

  1. Heat the oil in a wide non-stick pan over a medium heat. Add the cracked cardamom pods and the cinnamon piece. When tiny bubbles form around the spices, the oil is hot enough.

    ~2 min
  2. Add the finely diced onion. Cook for 5 minutes, stirring, until just starting to brown at the edges.

    ~5 min
  3. Stir in the ginger-garlic paste. Cook for 30 seconds.

    ~1 min
  4. Add all the chopped tomatoes. Cover and cook on a medium heat for 10 minutes, until the tomatoes are completely soft.

    ~10 min
  5. Mash the tomatoes hard with a potato masher to break them into a rough sauce, about 30-40 seconds.

    ~1 min
  6. Add the mixed curry powder, Kashmiri chilli powder, ground cumin, tandoori masala, ground coriander and black pepper. Stir through.

    ~1 min
  7. Add the loosened tomato puree. Stir hard, the gravy turns from red-orange to a deep rogan-red.

    ~1 min
  8. Tip the entire spiced tomato base into the slow cooker. Stir in the cubed chicken breast and the 100 ml hot water.

    ~3 min
  9. Cover and cook on low for 2 hours, or high for 1.5 hours, until the chicken is just cooked through and the gravy is rich.

    ~120 min
  10. For the last 30 minutes, stir in the cherry tomatoes. For the last 10 minutes, stir in the kasuri methi.

    ~30 min
  11. Stir in the fresh coriander, the yoghurt and the teaspoon of sugar with the heat off. Taste and adjust salt. Scoop off any excess oil from the top.

    ~2 min
  12. Serve with basmati rice or warm naan.

    ~1 min

Frequently asked

Can I use chicken thighs?
Yes, chicken thighs stay juicier still over the long cook and are the safer pick if your slow cooker runs hot. Use boneless thighs cubed the same size; no time change needed.
It's a tomato-led curry, what tomatoes matter?
Al is firm: vine-ripened, best quality you can afford. Salad tomatoes (anaemic, watery) give a thin, bland gravy. If your fresh tomatoes are mediocre, supplement with a tin of good Italian plum tomatoes for the deeper colour.
Why add the yoghurt at the end?
Yoghurt added to a hot acidic tomato gravy can split. Stirring it in at the very end with the heat off keeps the gravy silky and adds the dairy body Al describes as the magic finish. If you're worried, whisk the yoghurt with a tablespoon of warm sauce first to temper it, then fold into the pot.
Extraction notes (transparency): All major quantities clearly stated by Al. Mixed powder is Al's own 'basar' blend, Madras curry powder is the listed swap. Yoghurt 2 tbsp stated, sugar 1 tsp stated. Note: batch.json miscategorised this as 'lamb' from the source query, corrected to chicken (Al explicitly uses chicken breast, not lamb).
