Crispy, golden, and warmly spiced, these baked sweet potato chips hit that satisfying crunch you crave without relying on any of the citric acid preservatives that sneak into nearly every store-bought chip on the market. That's the frustrating reality of packaged snacks — citric acid shows up as a flavor enhancer or preservative in an enormous number of products, making the chip aisle a minefield. Here, the ingredient list stays clean and intentional: sweet potatoes, coconut oil, turmeric, ginger, and sea salt. The turmeric lends a gorgeous amber color and earthy depth, while the ginger adds just enough warmth to keep things interesting. Slicing the potatoes thin and uniform — ideally with a mandoline — is the real secret to getting that delicate, papery crisp rather than a chewy, limp result. The optional drizzle of fresh lemon juice at the end is a smart finishing touch that brightens the whole batch without introducing any processed additives. These are the kind of snack you make once and then find yourself making every single week.

Using a mandoline or a sharp knife, slice the sweet potatoes into rounds 1/16 to 1/8 inch thick — as uniform as possible so they bake evenly.
