Baked Kale Chips

Why This Baked Kale Chips Works

In the oven, the kale dries out slowly instead of roasting fast and hard. The low heat gives the water inside the leaves time to steam away without burning the edges right away. As the moisture leaves, the thin parts of the kale become light and crisp, kind of like very thin crackers. If the kale went into a hotter oven, the edges would scorch while the centers stayed a bit chewy.

Drying the kale well at the start matters a lot. Extra water on the leaves would steam and keep them soft, so the chips would stay bendy instead of snapping. Rubbing in the olive oil coats each piece in a thin layer of fat, which lets the leaves dry evenly and keeps them from sticking to the pan. The salt and powders cling to the oiled surface, so as the kale crisps, the seasoning stays on the chips instead of falling to the bottom of the tray. Letting them cool on the sheet finishes the drying, so they stay crunchy instead of going limp.

Mistakes To Avoid

Letting the kale go into the oven even slightly damp keeps steam trapped around the leaves. Instead of drying out, the pieces soften and wilt, and the chips come out chewy in the center instead of crisp all the way through.

Crowding the baking sheet so the kale overlaps creates little piles that never dry properly. The top bits may crisp, but the leaves underneath stay soft and sometimes turn a bit soggy and dark in spots.

Turning the oven hotter than 300°F to “speed it up” often scorches the thin edges before the thicker parts dry. The result is a mix of burnt, bitter edges and still-flexible centers that don’t really snap.

Skipping the step of massaging the oil onto the leaves leaves some pieces almost dry and others greasy. Dry spots burn and turn papery, while the oily ones get heavy and sometimes stay a little limp instead of light and crisp.

Pouring on too much salt at the start can be misleading because the raw leaves taste mild. Once the kale shrinks in the oven, that same amount of salt is concentrated on a much smaller chip, and the batch ends up harshly salty.
