Sweet potatoes hit different when they're sliced paper-thin and roasted until the edges go golden and caramelized. The combination of maple syrup, fresh sage, ground ginger, and turmeric gives these chips a warm, earthy sweetness that feels way more sophisticated than anything you'd pull from a bag. Coconut oil helps each slice crisp up beautifully in the oven, and the trick of patting the rounds completely dry before tossing them in the coating makes all the difference between a chip and a sad, soggy slice. Snack foods are one of those categories where hidden seafood-derived ingredients — like fish sauce, anchovy paste, or certain flavor enhancers — can sneak into otherwise innocent-looking products, so making your own from scratch is genuinely the cleanest move. Everything here is straightforward plant-based pantry staples, so you know exactly what you're eating. A final sprinkle of flaky sea salt right before serving pulls the sweet and savory flavors into perfect balance. These are the kind of snack that disappears fast, so consider making both sheet pans and calling it a single serving.

Preheat the oven to 375°F (190°C). Line two large baking sheets with parchment paper and set a wire cooling rack over one of them if you have one.
Using a mandoline set to 1/16-inch thickness, or a sharp knife, slice the sweet potatoes into rounds as uniformly thin as possible. Pat the slices dry with paper towels — the drier the slices, the crisper the chips.
