Butter chicken (murgh makhani) was invented at Moti Mahal restaurant in Daryaganj, Delhi, in 1947 by Kundan Lal Gujral — reportedly as a way to rescue leftover tandoori chicken by simmering it in a tomato, butter, and cream sauce. Gujral had developed tandoori chicken (cooking marinated chicken in a clay tandoor oven at 480°C/900°F) as his signature dish. The rich, silky makhani sauce was the solution to using the next day's leftover charred chicken without waste. The result became one of the most beloved dishes in the world.
The version most people encounter in restaurants is often a pale shadow — pre-cooked chicken cubes dropped into sauce made from tomato paste, heavy cream, and premixed spice powder. The real dish has two separate layers of flavor: the charred, yogurt-marinated chicken (which must be cooked separately at high heat to develop smoky caramelized edges) and the slow-built makhani sauce with whole spices, fresh aromatics, cashew cream, and the defining touch of kasuri methi (dried fenugreek leaves).
Combine all marinade ingredients and coat chicken thighs thoroughly. Marinate covered in the refrigerator for at least 2 hours; overnight produces significantly deeper flavor and more tender texture as the yogurt's lactic acid partially denatures the surface proteins. Cut thighs into large pieces (about 5cm) or leave whole — whole pieces are easier to manage under the broiler and stay juicier.
Melt butter in a heavy-bottomed pot over medium-high heat. Add whole spices (cardamom, cloves, cinnamon, bay leaves) and cook 60–90 seconds until fragrant and sizzling. Add diced onion and cook over medium heat, stirring occasionally, until deeply golden — 15–18 minutes minimum; do not rush this, properly caramelized onion is the flavor foundation. Add ginger and garlic; cook 2 minutes until raw smell disappears. Add Kashmiri chili powder and coriander; cook 1 minute. Add tomatoes and soaked cashews; season with salt; cook covered over medium-low heat for 20 minutes until tomatoes are completely broken down.
Remove the cinnamon stick and bay leaves (cardamom and cloves can be blended). Blend completely smooth in a standing blender (not immersion blender — a standing blender produces a finer emulsion). Strain through a medium-mesh sieve, pressing with a spoon to extract maximum liquid; discard solids. Return the smooth sauce to the pot over low heat.
Preheat broiler to maximum heat. Place chicken on a wire rack over a foil-lined baking sheet. Broil 12–15 minutes until the surface is well-charred in places, the yogurt marinade is caramelized to dark red, and the chicken is just cooked through. The char is not a mistake — it is the point; this is what the tandoor produces and what gives the dish its complexity. Rest 5 minutes.
With the blended, strained sauce on low heat: add remaining butter and stir to incorporate. Add cream and stir through. Add garam masala and the sugar/honey to balance acidity. Taste and adjust salt. Add the broiled chicken pieces; simmer gently 5–8 minutes to infuse. Off heat: rub kasuri methi between your palms until fragrant and add to the pot; stir through. Cover and rest 2 minutes before serving over basmati rice or with naan.
The deep brick-red color of restaurant butter chicken comes from Kashmiri red chili powder — a mild, vibrantly red dried chili that provides color without excessive heat. It is NOT the same as regular cayenne or hot chili powder. Kashmiri chili has about 1,000 Scoville units vs cayenne at 30,000–50,000; substituting cayenne 1:1 will make the dish far too spicy. If unavailable: use a 3:1 mix of sweet paprika to cayenne to approximate the color and mild heat. Find it at Indian grocery stores.
Butter chicken vs chicken tikka masala: Butter chicken (murgh makhani) has a sweeter, silkier, less tangy sauce with buttery richness and fenugreek finish. Chicken tikka masala (attributed to South Asian restaurants in the UK, reportedly invented in Glasgow) has a tangier, more acidic sauce without fenugreek. Both are excellent; they are different dishes with different origins.
