Combine your cubed chicken thighs with salt, pepper, paprika, garlic powder, onion powder, turmeric, cumin, ground ginger, Greek yogurt, and lemon juice. Stir to coat evenly, cover, and let it marinate for at least 2 hours (overnight if you have the time). This step is what gives the chicken its signature tenderness and flavor.
Heat olive oil in a large skillet over medium heat. Add the marinated chicken in batches, searing until browned on all sides. You’re not cooking it all the way through yet — just locking in flavor and giving it a golden crust. Remove and set aside.
In the same skillet, add a little more olive oil if needed, then toss in the diced onion. Sauté until translucent, then add garlic paste. Let it cook until fragrant — about 30 seconds.
Pour in your jar of butter chicken sauce, then stir in 2 tablespoons of butter for extra creaminess. Add the seared chicken back to the pan and simmer for about 10–15 minutes, or until the chicken is fully cooked and the sauce thickens slightly.
Spoon the butter chicken over fluffy basmati rice, add a sprinkle of fresh cilantro, and serve with warm naan on the side.
