Butter chicken — murgh makhani — was invented in Delhi at Moti Mahal restaurant by Kundan Lal Gujral in the 1950s. The origin story involves using leftover tandoori chicken and a tomato-butter-cream sauce to reheat it. Whether or not that's entirely accurate, the dish's logic is sound: the two components (char-kissed spiced chicken + silky makhani sauce) are made separately and united at the end. That separation is the technique — not a shortcut, but the actual method.
What makes butter chicken distinct from tikka masala (beyond the ownership debate)? The makhani sauce: fresh tomatoes or good canned tomatoes reduced with onion and cashews, blended smooth, then finished with butter, cream, and most importantly kasoori methi (dried fenugreek leaves). The kasoori methi delivers the characteristic slightly bitter, maple-tinged flavor that makes butter chicken identifiable even in a blind tasting. It's not optional.
Score chicken thighs with a knife (3–4 cuts per piece, about ½ inch deep). Toss with lemon juice, Kashmiri chili, and salt. Rest 20 minutes. This acid marinade begins tenderizing and the lemon brightens the flavor. Don't skip this step — the double marinade is standard in restaurant kitchens for a reason.
Mix yogurt marinade ingredients. Add to the chicken, coat thoroughly, cover, and refrigerate minimum 1 hour — overnight is better. The yogurt creates a protective coating that chars beautifully under the broiler while keeping the inside moist. It's also the reason butter chicken has that characteristic orange-red tinted crust.
Set oven to highest broil setting. Place chicken on a wire rack over a foil-lined baking sheet. Broil 8–10 minutes until deeply charred in spots and cooked through (internal 74°C/165°F). The char is not a mistake — it's the flavor. Flip once halfway. Cut into bite-sized pieces after resting 5 minutes. Don't wash the pan; the drippings can enhance the sauce if added.
In a large, heavy-bottomed pan, melt butter with oil over medium heat. Add onion and cook until deeply golden, 15–18 minutes — don't rush. Add garlic and ginger; cook 3 minutes more. Add spices and toast 1 minute. Add tomatoes and cashews. Simmer 20 minutes until tomatoes break down and oil begins to separate. Cool slightly and blend until very smooth — pass through a strainer for restaurant-level silkiness. This step can be done while the chicken marinates.
Return blended sauce to the pan over medium-low heat. Add butter and cream; stir until incorporated. Add the kasoori methi — crush it between your palms before adding to release the oils. Taste and adjust with salt and sugar (the sugar balances tomato acidity, not sweetness). Add the broiled chicken pieces. Simmer together 5–8 minutes so the chicken absorbs some sauce. Finish with a drizzle of cream. Serve with naan, basmati, or paratha.
The signature brick-red color of butter chicken comes from Kashmiri dried chilies or Kashmiri chili powder — not generic red chili powder. Kashmiri chili is very low in heat (similar to mild paprika) but intensely red and slightly fruity. Substituting regular chili powder gives heat without color; substituting pure paprika gives color without depth. Good compromise: 1 part regular chili + 1 part sweet paprika. The real thing is available at any South Asian grocery and is worth having.
