According to an employee, there are no freezers at any location, only coolers, and each morning, the meat is prepped straight from the cooler, dated, and rotated to prevent any "old" meat from being reused. Another employee, per Reddit, admits that the burger patties are "technically frozen," stored in a cooler that's just below freezing temperature, but only for a brief period instead of sitting in a freezer.

Five Guys also uses peanut oil to deep-fry its French fries, which, as founding member Jerry Murrell explains, gives the fries a "melt-in-your-mouth buttery taste." Fryers are kept strictly for fries instead of "doubling up" on anything else from the menu, and the potatoes are cut in-store, washed, and then cooked twice — once to "pre-cook" and then to finish them off.
