In a large mixing bowl whisk turmeric, ginger, salt, chili powder, and cinnamon. Toss chicken to thoroughly coat in spices.
Over medium heat melt butter in a cast iron pan. Add onion and garlic and good for 3 minutes.
Add chicken and cook for 3-5 minutes, almost entirely through but not quite. Add in heavy cream and tomato paste. Mix until a warm, orange color sauce appears. Turn down the heat and cover with a lid. Cook for 5-7 minutes.
Our family often serves this butter chicken over a 1:1 blend of white rice and cauliflower rice (gotta sneak in those veggies where you can!). We like to have Stonefire naan from Costco too on the side too! It’s the perfect dipper for the sauce!
