Turn your Instant Pot to the saute, add 3 tablespoons unsalted butter and let melt. Once butter has melted, add in ¼ cup minced onion and saute for 2-3 minutes, stirring often, until onions have softened. Add in 5 cloves garlic minced and 2 teaspoons fresh ginger (grated) and saute for one minute longer.
Add 1 tablespoon tomato paste, 1 teaspoon garam masala, 1 teaspoon ground coriander , 1 teaspoon cumin, 1 teaspoon paprika, ½ teaspoon turmeric, and ½ teaspoon salt and saute for 1-2 minutes, or until spices are fragrant. Be careful not to burn the spices or tomato paste. Turn the Instant Pot OFF by hitting cancel.
Add in ¾ cup low-sodium chicken broth and scrape up any browned bits on the bottom of the inner pot. Add 1 pound chicken breasts or thighs, boneless and skinless to the mixture and then top with 15 ounces crushed tomatoes .
Close the lid and set to cook on high pressure for 5 minutes. (Hit Manual or Pressure Cook and adjust the time to 5 minutes using +/- buttons.)
Once the cooking time has elapsed, let the pressure release naturally for 10 minutes. Do a quick pressure release of any remaining pressure to open the lid to the Instant Pot.

Notes
To make Dairy Free Butter Chicken, use coconut oil in place of butter and full-fat canned coconut milk in place of heavy cream. When using an 8-quart Instant Pot, you may want to add in an additional ¼ cup stock to prevent a burn warning. I have made this many times in a 6-quart and 8 quarts with no issues, but have found some 8-quart models are a bit more finicky. Spices: Be sure to use ALL the spices listed for the best results and be sure your dried spices are no older than 6 months old for the most flavor. To Make Rice at the same time: Place rinsed long-grain white rice in a stainless steel bowl with an equal amount of water. Place a trivet above the chicken and set the bowl on the trivet. The rice needs a bit longer to account for the stainless steel bowl, so the cooking time of 5 minutes with at least 10 minutes of natural pressure release.Leftover Instant Pot Butter Chicken will last in the fridge for 3 days. You can also freeze for one month. Just let the butter chicken defrost overnight in the fridge and warm in 30-second intervals in the microwave. I have had no issues freezing this recipe when I have used heavy cream.
