Basic Instant Pot Tri Tip: If you would like to make a more traditional instant pot tri tip, simply omit the ranch and fajita seasoning, the diced tomatoes and the green chilies. Use 1 cup water, 2 au jus packets, 3 whole cloves or garlic and one onion slice into thin strips or chopped.Mississippi Roast Instant Pot Tri Tip: Omit fajita seasoning, diced tomatoes and green chilies. The classic Mississippi roast recipe uses chuck roast (pot roast) and also adds a stick of butter. While the butter adds another dimension of flavor, I don't find that the extra butter is necessary as the fattiness of the meat is more than enough. You can't go wrong either way.Pressure Cooker Tri Tip: An instant pot is a multi functional kitchen gadget that has a pressure cooker functionality. If you have a standard pressure cooker, bring your pressure cooker to high pressure and cook for the same amount of time as this recipe indicates (60 minutes).
