America's favorite way to eat Idaho® Potatoes has always been mashed, and there are more potatoes consumed on Thanksgiving than any other day. Now, thanks to a petition to the National Day Archives by the Idaho Potato Commission, America will officially celebrate the first-ever National Mashed Idaho® So enjoy a heaping helping this Thanksgiving. Because when you serve certified Mashed Idaho® Potatoes, everything else is just gravy. Potato Day this Thanksgiving. And on every Thanksgiving going forward.
