Crispy, golden, and fragrant with garlic and rosemary, these oven-baked sweet potato chips are the kind of snack that disappears fast. Most store-bought chips are fried in canola, sunflower, or other refined vegetable oils, so finding a truly clean option on the shelf is nearly impossible — making a homemade batch the obvious move. Here, coconut oil does all the work, coating each paper-thin slice in a way that encourages even crisping without any of the industrial oils you're trying to avoid. The mandoline technique is key: getting those slices uniformly thin means they bake up shatteringly crisp rather than chewy or soft in the middle. A touch of ground ginger alongside the rosemary and garlic gives the seasoning an unexpected warmth that makes these way more interesting than a plain salted chip. Watch them closely in that final stretch of baking — pulling them just as the edges deepen is what separates perfectly crisp chips from bitter ones. Let them cool on the pan and they'll firm up into exactly the satisfying crunch you're after.

Preheat the oven to 375°F (190°C). Line a large baking sheet with parchment paper.
Using a mandoline or a sharp knife, slice the sweet potatoes into rounds about 1/16-inch (1.5 mm) thick — thin enough to see light through when held up, but not so thin they tear.
