If you love fries, the best day to celebrate the popular potato side is on National French Fry Day, July 11, 2025. No matter your favorite fry — crinkle-cut, curly, waffle, steak or shoestring — all are a staple anytime there’s a burger on the plate. And there’s the debate over dipping sauces. Besides the standard ketchup, you find fans of everything from ranch dressing to mayo…or even a milkshake.

There’s also a fierce debate about which restaurant chain has the best fries. Whichever fries are your favorite, fries are always best when they’re served hot and fresh. There’s no debate about that!
