Baked Potato Chips

Why This Baked Potato Chips Works

In the oven, the thin potato slices dry out and firm up. Each slice starts with a lot of water inside. With steady heat, that water slowly steams out, especially because the slices are only about 1/8 inch thick. As the moisture leaves, the potato flesh goes from soft and bendy to stiff and crisp.

Olive oil coats every slice, so the potatoes don’t just dry out in random spots. The oil spreads the heat more evenly and lets the surface brown instead of burning. Salt sticks to the oiled surface and pulls out a bit more water, which helps the chips crisp faster. Any paprika or garlic powder stays on the outside and toasts slightly, so the seasoning clings to each chip instead of falling off.

By the time they come out of the oven and cool on the rack, the slices have lost enough moisture to stay crunchy. Cooling lets the chips firm up even more, so they snap instead of bend.

Mistakes To Avoid

Cutting the potato slices too thick means the centers stay soft while the edges start to brown. By the time the middle cooks through, the outside can turn hard or even burn, so the chips never get evenly crisp.

Crowding the baking sheet causes steam to get trapped between the slices. Instead of drying out and crisping, the potatoes stay soft and bendy, and some spots can stick to the parchment and tear.

Skipping the flip halfway through baking leaves one side of each slice pressed against the hot pan the whole time. That side can get too dark or burn while the top side stays pale and leathery instead of crisp.

Rinsing the potatoes after slicing and not drying them well leaves a lot of water on the surface. Extra moisture makes the oil slide off, so the slices steam in the oven and come out patchy, with some parts crisp and other parts still soft.
