The trick to preventing your French fries from getting soggy comes from a former McDonald’s employee. According to Bruno Bouchet from Sydney, Australia, keeping your fries crispy is all about how you arrange them in the paper takeout bag (via Men’s Health). “The error everyone makes is closing the top of the bag that contains the [fries],” Bouchet, who worked at McDonald’s as a teenager, told WOMI. He added that while you may think closing the bag keeps your fries hot, it actually traps in steam which creates moisture inside the bag — and thus, mushy fries. So leave your bag open.
For even better results, Bouchet shared that the placement of your fries in the bag can make a big difference. “Stack the [fries] so they’re horizontally at the bottom and put the burgers on top of the [fries] to keep them warm,” he recommended. Do this, and he says you’ll never have soggy fries again.
