Chicken Korma Recipe
A scientifically optimized recipe for authentic Chicken Korma, featuring a velvety, emulsion-stabilized yogurt sauce and deeply caramelized onions.
- Stabilized yogurt emulsion prevents curdling and ensures a perfectly smooth, velvety sauce.
- Slow-caramelized onion paste provides a rich, authentic sweetness without excess sugar.
- Gentle poaching technique keeps the chicken breast or thigh meat incredibly tender and juicy.
The secret to an authentic chicken korma lies in the delicate emulsification of spiced yogurt and deeply caramelized onions. Unlike high-heat curries, this Mughlai classic demands a low-and-slow simmering technique to prevent the dairy from curdling and to keep the chicken tender.
Temperature control is everything.
When yogurt is heated rapidly, its protein matrix collapses, squeezing out water and curdling the sauce. By whisking in a stabilizer and tempering the mixture with warm pan juices, you create a resilient emulsion that coats the meat beautifully, much like the technique used in a rich Chicken Tikka Masala.
Caramelizing the onions slowly is equally critical, as it coaxes out natural sugars for a deeply sweet flavor profile.
This slow browning process relies on the Maillard reaction, converting amino acids and reducing sugars into complex flavor compounds. It provides the signature golden hue and nutty undertone characteristic of royal North Indian cuisine, similar to other slow-cooked curries.
Never rush this foundational step.

Chicken Korma
Ingredients
- 1.5 lbs (680g) boneless, skinless chicken thighs, cut into 1.5-inch pieces
- 2 large yellow onions, thinly sliced
- 3 tablespoons ghee or neutral oil
- 1 cup full-fat Greek yogurt (such as Fage)
- 1 tablespoon cornstarch or chickpea flour (besan)
- 1.5 tablespoons ginger-garlic paste
- 1 teaspoon garam masala
- 1 teaspoon ground coriander
- 0.5 teaspoon ground cumin
- 0.5 teaspoon Kashmiri chili powder
- 0.25 teaspoon ground turmeric
- 0.25 cup raw cashews, soaked in warm water for 15 minutes and blended into a smooth paste
- 1 teaspoon Diamond Crystal kosher salt
- 0.5 cup water or low-sodium chicken stock
Directions
- Heat the ghee or neutral oil in a heavy-bottomed Dutch oven over medium heat. Add the sliced onions and cook, stirring frequently, for 15 to 20 minutes until they are deeply golden brown and caramelized, taking care not to burn them.
- Remove the caramelized onions with a slotted spoon, leaving the fat in the pan. Let the onions cool slightly, then blend them with 2 tablespoons of water into a smooth paste; set aside.
- In a bowl, whisk together the full-fat Greek yogurt, cornstarch, garam masala, coriander, cumin, Kashmiri chili powder, turmeric, and kosher salt until completely smooth.
- Return the Dutch oven to medium-low heat. Add the ginger-garlic paste and sauté for 1 minute until fragrant, then add the chicken pieces and sear for 3 to 4 minutes until the exterior turns opaque.
- Reduce the heat to low. Gradually whisk 0.25 cup of the warm pan juices into the yogurt mixture to temper it, then pour the tempered yogurt, onion paste, and cashew paste into the pot, stirring constantly to establish the emulsion.
- Pour in the water or chicken stock, cover the pot with a tight-fitting lid, and simmer gently on low heat for 15 to 20 minutes until the chicken reaches an internal temperature of 165°F (74°C). </
Notes
Follow these critical guidelines to ensure a flawless, restaurant-quality emulsion.
- Brand-specific recommendation: Use Diamond Crystal kosher salt; if substituting with Morton's kosher salt or fine table salt, reduce the volume by half (0.5 teaspoon) to prevent over-salting.
- Science-backed rationale: Adding a starch like cornstarch or chickpea flour physically interferes with the dairy proteins, preventing them from bonding tightly and curdling when exposed to heat and acid.
- Preemptive workflow warning: If you skip tempering the yogurt before adding it to the hot pan, the thermal shock will instantly break the emulsion. Prevent this by slowly whisking warm pan liquid into the cold yogurt first.
- Storage behaviour note: After 24 hours in the refrigerator, the starch retrogradation process may cause the sauce to thicken significantly and slightly separate. Whisk in a tablespoon of warm water during reheating to restore the original creamy texture.
- Equipment alternative: A heavy-bottomed Dutch oven is ideal for heat retention; if using a thin stainless steel pan, reduce the burner heat to low and stir more frequently to prevent the cashew paste from scorching on the bottom.
Serving Suggestions
Complete this luxurious Mughlai meal by pairing the rich, creamy korma with elements that offer textural contrast and bright acidity.
- Warm garlic naan (the soft, chewy texture is perfect for scooping up the velvety korma sauce).
- Fragrant basmati rice (fluffy, individual grains absorb the curry without becoming mushy).
- Quick-pickled red onions (the sharp acidity cuts through the richness of the cashew and yogurt base).
- Fresh cilantro leaves and julienned ginger (provides a bright, herbal contrast to the warm spices).
Storage and Reheating
Store leftover chicken korma in an airtight glass container in the coldest zone of your refrigerator for up to 3 days. Glass is preferred over plastic as the fat-soluble spices can stain and retain odors in plastic vessels.
Freezing is not recommended for this recipe. The delicate yogurt and cashew emulsion will break during the freezing and thawing process, resulting in a watery, grainy texture upon reheating.
To reheat on the stovetop, place the korma in a small saucepan over low heat. Add 1 to 2 tablespoons of water or chicken stock to loosen the sauce, and stir constantly until the chicken is warmed through to 165°F (74°C).
If using a microwave, heat in 30-second intervals at 70% power, stirring thoroughly between each interval to distribute the heat evenly and prevent the sauce from splitting.
Ingredient Substitutes
You can adapt this recipe to suit different dietary needs or pantry availability with minor technical adjustments.
- Chicken Thighs to Chicken Breasts: Substitute 1.5 lbs of thighs with 1.5 lbs of boneless chicken breasts. Reduce the final simmering time by 5 minutes to prevent the leaner breast meat from drying out.
- Greek Yogurt to Coconut Cream: Substitute 1 cup of Greek yogurt with 1 cup of unsweetened coconut cream for a dairy-free option. Omit the cornstarch, as coconut cream does not contain casein proteins and will not curdle under heat.
- Cashew Paste to Sunflower Seed Paste: Substitute 0.25 cup of raw cashews with 0.25 cup of raw sunflower seeds (soaked and blended) for a nut-free alternative. The sauce will have a slightly earthier flavor profile but will retain its signature thickness. </
Master the art of emulsification, and this chicken korma will become a staple in your culinary repertoire. By respecting the science of temperature control and starch stabilization, you can consistently reproduce a flawless, royal-quality curry at home. Keep your heat low, your onions deeply browned, and enjoy the process.
