These mashed potatoes are indulgently buttery, creamy, tangy, and made with a subtle hint of garlic (or you’re welcome to add much more, if you’d like). They are perfectly dense and thick (not the whipped and ultra-light variety). They feature not one, but two popular kinds of potatoes (whose skins you are welcome to leave on or peel off). They can be mashed as smooth or as chunky as you prefer. Oh, and they’re also incredibly easy to make ahead of time and reheat in the microwave if you have a busy menu lineup and would like to prep them ahead of time.
