The secret to a smooth, stress-free Thanksgiving is prepping what you can ahead of time. And these creamy make-ahead mashed potatoes should be at the top of your list. In fact, you might have found your mashed potato recipe soulmate. A mixture of meltingly tender leeks cooked in butter and kissed with garlic is stirred into hot, just-riced potatoes along with sour cream and half-and-half. Using a potato ricer allows for fluffier, clump-free potatoes, but fret not, use a masher if it's what you've got on hand. These creamy mashed potatoes can be made up to three days ahead, and simply reheated low and slow with a bit more half-and-half.
