Thin-sliced sweet potatoes hit differently when they come out of the oven golden, fragrant, and genuinely crispy. Coconut oil, fresh rosemary, thyme, and a touch of turmeric do all the heavy lifting here, turning humble root vegetables into something that feels almost fancy. The garlic gets tossed right in with the slices before baking, so every chip picks up that savory, aromatic depth without any extra fuss. Slicing uniformly thin — ideally with a mandoline — is the real secret to getting that satisfying crunch, and the wire rack setup means hot air circulates underneath so nothing goes soggy. Many packaged chips and seasoning blends sneak in spices you didn't ask for, so making these at home gives you full control over exactly what goes into the bowl. A scatter of fresh parsley at the end adds a little brightness and color that makes the whole tray look like it came from a restaurant snack menu. These are best eaten right away while the edges are still curling and crisp, though they rarely last long enough to test that theory.

Preheat the oven to 375°F (190°C). Line two large baking sheets with parchment paper and set a wire rack on top of each, if available — this promotes airflow and crisper edges.
Using a mandoline set to 1/16-inch (about 1.5 mm) or a very sharp knife, slice the sweet potatoes into rounds as uniformly thin as possible. Uniform thickness is the single most important factor for even baking — thicker slices will stay chewy while thinner ones crisp.
