Whole spice chicken curry with mustard oil — the everyday non-veg of Bihari households

Ingredients

Method

  1. About Bihari Chicken Curry: The Bihari chicken curry is a robust, deeply flavoured non-vegetarian dish that uses mustard oil instead of refined oil, whole spices for layered aromatics, and a relatively dry-cooking technique that concentrates the masala onto the chicken pieces. It tastes distinctly different from the Punjabi or Bengali chicken curries — sharper, hotter, and with a clear mustard note throughout.
  2. Choose bone-in chicken: Use 1 kg of bone-in chicken pieces — thighs, drumsticks, and curry-cut bone-in pieces work best. Bone-in chicken produces dramatically more flavourful curry than boneless. Avoid breast meat for this recipe — it dries out during the long cook.
  3. Clean the chicken: Wash the chicken pieces under cold running water. Pat dry with kitchen paper. Drying matters — wet chicken will not sear properly and instead steams in its own moisture.
  4. Prepare the marinade: In a wide bowl combine 1 tsp turmeric powder, 1 tsp salt, and 2 tbsp ginger-garlic paste (or grind 5 garlic cloves and a 2-inch piece of ginger together with a splash of water). Mix well.
  5. Marinate the chicken: Add the chicken pieces to the marinade. Massage the marinade into every piece, including under the skin if any. Cover and let marinate for 30 minutes minimum at room temperature, or up to 4 hours in the fridge. Longer marination produces more flavour.
  6. Prepare the onions: Take 2 medium onions. Peel and slice thinly into half-moons. The Bihari chicken curry uses sliced rather than chopped onion — sliced onion caramelises more deeply and produces a richer gravy.
  7. Prepare the tomatoes: Take 2 medium tomatoes. Chop finely or, even better, blend to a smooth puree. Pureed tomato gives a smoother gravy.
  8. Prepare the whole spices: Have ready 1 bay leaf, 3 green cardamom pods (lightly cracked), 3 cloves and a 1-inch cinnamon stick (broken in half). These are not optional — they are the foundation of the curry's aroma.
  9. Heat the mustard oil correctly: Pour 2 tbsp mustard oil into a heavy-bottomed pot or kadhai over high heat. Heat for 1-2 minutes until the oil is smoking heavily and turns paler in colour — this completely removes the harsh raw mustard sharpness. This step is critical for chicken curry; raw mustard oil and chicken do not work well together.
  10. Reduce heat and temper: Reduce heat to medium. Add the bay leaf, cracked cardamom pods, cloves and cinnamon stick to the hot oil. Fry for 30 seconds — they will sizzle and the kitchen will fill with their aroma.
  11. Fry the onions: Add the sliced onions. Stir-fry on medium heat for 12-15 minutes, stirring every minute, until deep golden brown — almost mahogany at the edges. Take your time. Pale onions produce pale, weak curry; deep golden onions produce rich, deep curry.
  12. Add the tomatoes: Tip in the chopped or pureed tomatoes. Cook for 8-10 minutes on medium heat, stirring every 2 minutes, until the tomato has fully broken down into a thick paste and oil starts to separate at the edges.
  13. Add the dry spices: Sprinkle in 2 tsp red chilli powder and 1 tsp coriander powder. Stir for 1 minute — the masala will turn a beautiful rust-red colour.
  14. Add the marinated chicken: Add the marinated chicken pieces along with any leftover marinade. Stir well to coat every piece in the masala. The pan will hiss as the chicken hits the hot masala.
  15. The sear stage: Cook on medium-high heat for 8-10 minutes, stirring and turning the pieces every 2 minutes. The chicken will release some liquid initially, then start to dry and brown. The masala will deeply coat each piece. This searing is what gives the dish its distinctive Bihari character.
  16. Add water and salt: Pour in 1/2 cup hot water. Add salt to taste — usually 1 tsp, but the marinade already had salt so taste before adding. Stir well to lift any masala sticking to the bottom.
  17. The slow simmer: Reduce heat to low. Cover the pot tightly with a lid. Cook for 25-30 minutes, lifting the lid every 8-10 minutes to gently turn the chicken pieces and check the gravy. Add 2-3 tbsp hot water only if the bottom looks dry.
  18. Check doneness: Pierce a thick chicken piece with a knife — the juice should run clear, not pink. The meat should be tender and pull easily from the bone. The gravy should be thick and clinging to the pieces, not watery.
  19. Final flavour adjustments: Open the lid. If the gravy is watery, increase heat to medium-high and cook uncovered for 3-4 minutes to reduce. If too dry, stir in 2-3 tbsp hot water. Taste and adjust salt or chilli.
  20. Add garam masala (optional): Sprinkle 1/2 tsp garam masala over the curry. Stir gently. Cook 1 more minute. Garam masala adds a final aromatic warmth.
  21. Garnish and serve: Switch off heat. Sprinkle 2 tbsp finely chopped fresh coriander over the top. Serve hot with hot rotis, paratha or steamed rice. Bihari chicken curry tastes even better the next day after the chicken has soaked in the gravy overnight — store in the fridge and reheat gently.
