Sweet potato chips from scratch hit differently than anything you'd grab off a store shelf, and this version layers in warm sage, ginger, and turmeric for a flavor combination that feels almost autumnal. The touch of maple syrup in the coating gives the edges a subtle caramelized sweetness that plays beautifully against the earthy spice. Coconut oil keeps everything dairy-free and helps the slices crisp up in the oven without any fuss. The real trick here is slicing the potatoes as thin and uniform as possible — a mandoline makes this effortless — and patting them completely dry before tossing them in the coating, since moisture is the enemy of a truly crispy chip. Baking in a single layer and flipping halfway through ensures even color and that satisfying snap when they cool. For anyone navigating tree nut allergies or sensitivities, this is the kind of snack recipe that's genuinely worry-free — every ingredient is straightforward, and there's nothing hiding in the pantry list. Finish with a pinch of flaky sea salt and you've got a snack that disappears fast.

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.
