Place the butter, chopped onions, garlic, ginger, and all spices in the Instant Pot. Set on Sauté for 5 minutes. Stir to make sure the ingredients don't burn. Once the onions are soft, turn off.
Pour 1/2 cup water into the pot. Then use a wooden spoon to scrub the debris off the bottom of the pot. (This ensures the burn notice will not go off!)
Add the chopped chicken thighs and canned tomato sauce. Lock the lid into place and turn the Instant Pot on Pressure Cook High for 7 minutes. Once finished, turn the Instant Pot Off, then perform a Quick Release to release the steam pressure. Once the valve button drops, unlock the lid and remove.
Stir in the heavy cream. Set the Instant Pot on Sauté again and simmer for 2-5 minutes to thicken the sauce. Sprinkle with chopped cilantro and serve with basmati rice.

Notes
Don't have an Instant Pot? You can make this recipe in the slow cooker! Follow step 1 on the stove top, then transfer the onions and spices to a slow cooker. Add the tomato sauce and chopped chicken. Cover and slow cook for 6-8 hours on low. Then stir in the cream and serve.Burn Notice: Some Instant Pot users have reported they get a "burn notice" with this recipe. Although I have not experienced this personally, different models of IPs vary a little in the cooking process. If your IP is prone to flash the burn notice, be sure to thoroughly scrub the debris off the bottom of the pot before moving onto step 3. You can even add a little water to make sure this does not happen... 1/2 cup water should do the trick!
