Homemade potato chips already feel like a treat, but this ginger-scallion version takes the whole snack game somewhere genuinely exciting. Thin-sliced russet potatoes get tossed in garlic-infused oil with freshly grated ginger and white pepper before hitting a hot oven, and the result is deeply savory, aromatic, and impossibly crispy. The trick is getting those slices paper-thin and bone-dry before they go in — that extra step is what separates a truly shatteringly crisp chip from a sad, chewy one. Once they come out of the oven, a shower of fresh scallion greens and an optional drizzle of toasted sesame oil adds brightness and a nutty finish that makes these feel almost restaurant-worthy. For anyone navigating a fungi-free diet, packaged snacks can be a minefield of hidden flavoring agents and seasoning blends that aren't always transparent on the label — making these from scratch means you know exactly what's in every bite. They're fantastic straight from the bowl while still warm, but they hold up beautifully on a wire rack if you want to make a batch ahead for a crowd.

Preheat the oven to 400°F (205°C). Line two large rimmed baking sheets with parchment paper.
Using a mandoline or a sharp knife, slice the potatoes crosswise as thin as possible — about 1/16 inch (1–2 mm). Pat the slices thoroughly dry with paper towels; the drier they are, the crisper the chips.
