In planning your Thanksgiving menu, there are tons of holiday side dishes! Some years will call for green bean casserole while other times you'll choose an unexpected Brussels sprouts recipe. But if there's one side dish that always makes its way onto the table, it's mashed potatoes. Whether it's Ree Drummond's creamy mashed potatoes, a quick Instant pot mashed potatoes, or something with added flavor like roasted garlic mashed potatoes, there's no denying this classic Thanksgiving recipe is a must-have. In fact, we love mashed potatoes so much that we sometimes make more than we can eat in one sitting. Luckily, as Ree says, "Thanksgiving leftovers are one of the best parts about Thanksgiving!"
