This keto butter chicken is rich, creamy, and incredibly easy to make. It uses just a handful of ingredients while still delivering the classic flavors of butter chicken.
Season the chopped chicken evenly with salt and black pepper.
Heat the avocado oil in a large pan over medium- high heat. Add the chicken and cook for 5–6 minutes, stirring occasionally, until browned and cooked through. Remove from the pan and set aside.
Reduce the heat to medium and add the butter to the same pan. Once melted, add the tomato purée and stir until smooth.
Add the kasuri methi and water, mix well, cover, and cook for 5 minutes. The oil should begin to separate slightly from the sauce.
Reduce the heat to low and stir in the heavy cream until fully emulsified.
Return the chicken to the pan and cook gently for about 1 minute, just until heated through.
