Cold french fries are often considered one of the most impossible leftovers to save. Once they cool, the water inside the starchy center escapes toward the crispy outer layer, leaving the insides grainy and the outsides soggy. It's a disappointing result.
Trying to heat them back up in the oven doesn’t do much— it simply makes them taste like warm cardboard instead of cold cardboard—and deep-frying them again requires plenty of oil with subpar results. The most effective and refined method to reheat fries and restore their crispiness is by using the waffle maker.
However, I must point out that these waffle fries won’t be quite the same as fresh ones, since there’s no simple way to rehydrate the starches. But pressing them in the waffle maker will help remove the moisture that’s made them soggy, creating crispy, crunchy sections (more surface area), with a texture similar to a home-style breakfast potato.
Simply heat your waffle maker to its highest setting, place a handful of cold, sad fries in the center, and press them between the hot plates. Once you notice dark, golden brown pockets forming on the fries, remove them and serve immediately. They’re great with ketchup or a spicy mayo, but even better when topped with a fried egg. Their extra-crispy texture makes them perfect for smothering in gravy.
