French Fry Casserole has become a guilty pleasure at our house. This is something we concocted. You may be familiar with Tator Tot Casserole (recipe below). Somehow that classic morphed into something else at our house. One night my brother brought home leftover French fries. And it wasn’t just a few fries, it was a boatload. He brought the fries into the house to make sure no one wanted them before he threw them away. We don’t really enjoy cold fries, and don’t think they reheat particularly well. But this was such a huge portion of French fries, it seemed to be wasteful to throw them away. So this was the practical beginning of French Fry Casserole. It was our solution for what to do with leftover French fries.
