Parsnips are an underrated root vegetable, and slicing them paper-thin and roasting them into golden, shatteringly crisp chips is one of the best things you can do with them. The warm spice blend of turmeric and ginger gives every chip a subtle, earthy depth, while the optional rosemary adds a fragrant herbal note that makes the whole kitchen smell incredible. Coconut oil helps each slice crisp up beautifully in the oven without relying on any dairy or iodine-containing ingredients, so the snack stays completely on-plan. The wire rack trick is the real secret here — elevating the slices allows hot air to circulate underneath, which means you get genuine crunch rather than a soggy, steamed result. People following a low-iodine protocol often find themselves missing satisfying snack foods, and this recipe fills that gap without any compromise on flavor or texture. Sea salt, fresh aromatics, and a hot oven are all you need to turn a humble root vegetable into something genuinely craveable. Let them cool fully on the rack before you dig in — they firm up even more as they rest, and the patience is absolutely worth it.

Preheat the oven to 375°F (190°C). Line two large baking sheets with parchment paper and set a wire rack on each sheet.
Using a mandoline set to 1/16-inch thickness, or a sharp knife, slice the parsnips into rounds as uniformly thin as possible. Pat the slices thoroughly dry with paper towels — any surface moisture will steam rather than crisp.
