These Vegan Mashed Potatoes from the Simple Vegan Blog are a great alternative to mashed potatoes with butter. My guys agree that they taste just as good if not better than the buttery version, and everyone gets to eat them. I won’t call them a substitute, because that implies that you would only have this if you can’t have something else. These are so good that even if we could have butter, I think we would still choose to do them this way.
Note: I use rice/quinoa milk, but any plant milk will work fine.
