If you don't eat butter, you can use 1/4 cup olive oil, then use additional milk (dairy-free milk, if needed) or broth for the rest of the liquid. We've done this in our Instant Pot Mashed Potatoes loads of times. Vegan butter (like Earth Balance) also works! If dairy's not a problem, you can also use sour cream, cream cheese, or plain Greek yogurt in place of all or part of the butter.
