Description

A rich, slow-cooked Indian lamb curry (Rogan Josh) infused with bold spices, coconut milk, and tomatoes, creating a tender and comforting dish perfect for family dinners or meal prep.


Ingredients

1 large brown onion

4 cloves garlic

1 thumb-sized piece of ginger

400g chopped tomatoes

250ml chicken stock

1 tsp ground cinnamon

2 tbsp curry powder

1 tsp ground cumin

1 tsp turmeric

400ml coconut milk

1 tbsp dark soy sauce

1.2kg leg of lamb, cut into chunks

100g spinach

Fresh coriander, for garnish

Greek yogurt (optional, for serving)

Naan bread (optional, for serving)


Instructions

  1. Blend the onion, garlic, and ginger with about 250 ml of water until smooth and transfer to a pot.
  2. Simmer the mixture on low with the lid on for 15 minutes.
  3. Add oil and cook uncovered until the base turns deep golden brown.
  4. Stir in the lamb pieces and cook for 8–10 minutes until browned.
  5. Add chopped tomatoes, chicken stock, cinnamon, curry powder, cumin, and turmeric. Bring to a boil, then simmer covered.
  6. Cook in a slow cooker on Low for 6–8 hours or High for 3.5–4 hours, or simmer on stovetop for 1 hour 45 minutes until lamb is tender.
  7. Stir in coconut milk and soy sauce, bring back to a simmer, then turn off heat.
  8. Add spinach, cover, and let wilt for 5 minutes.
  9. Top with fresh coriander and serve with rice and naan.

Notes

  • Can substitute spinach with kale or Swiss chard.
  • To make it dairy-free, omit yogurt and add more coconut milk.
  • Chickpeas or paneer can replace lamb for a vegetarian version.
  • Flavors deepen if made ahead and reheated the next day.
  • Trim lamb fat to reduce oiliness in the final dish.
