The story behind this recipe
- One lazy Sunday afternoon, I was craving a crunchy snack but didn’t want to fuss with oil or frying. I remembered how my grandmother used to bake thin slices of sweet potato for a simple, wholesome treat, and I thought, why not modernize that with a touch of my own? The smell of roasting sweet potatoes, caramelized and smoky, instantly transported me back to childhood afternoons in her kitchen.
- This recipe came together out of a need for something satisfying yet easy, with the kind of comfort that comes from knowing exactly what’s going into your snack. It’s become a little ritual for me—baking a batch when I need a quick, guilt-free crunch after a long day. Sometimes, simple is just enough to turn a regular evening into a cozy moment.

Key ingredients and their quirks
- Sweet potatoes: I prefer a firm, bright orange one—I find they turn out the sweetest and most vibrant. Use a sharp knife to slice paper-thin for maximum crispness, and watch the edges—they’ll curl when done.
- Olive oil: Just a light brush helps the chips crisp up without feeling greasy. Skip it if you want a totally oil-free version, but they won’t be quite as shiny or crispy.
- Salt: I like a generous sprinkle right after baking—brings out that sweet-salty contrast. You can swap with smoked paprika or chili powder for a smoky kick or skip altogether if you’re avoiding sodium.
- Spices: Cinnamon or cumin sprinkle well with the sweet potato’s natural earthy flavor. Keep it light—these chips are all about highlighting that mellow sweetness and smoky aroma.
- Optional toppings: A pinch of sesame seeds or a drizzle of honey can add texture and a touch of extra flavor. Use sparingly so they don’t overpower the natural sweetness.
- Baking sheet: Use a rimmed sheet lined with parchment—no sticking, easy cleanup. The thin slices need plenty of air circulation to crisp evenly, so don’t overcrowd.

Equipment & Tools
- Mandoline slicer: Ensures even, paper-thin slices for maximum crispness.
- Baking sheet: Provides a flat surface for baking, with space for air circulation.
- Parchment paper: Prevents sticking and makes cleanup easier.
- Silicone brush: Lightsly coats slices with oil for crisping and flavor.
- Cooling rack: Allows air to circulate around chips for even cooling and crisping.
Step-by-step guide to baked chips
- Gather your equipment: a sharp knife, a mandoline slicer (if available), a baking sheet, parchment paper, a silicone brush, and a cooling rack. Preheat your oven to 150°C (300°F).
- Wash and dry the sweet potatoes thoroughly. Using the mandoline or a sharp knife, slice the sweet potatoes into very thin, even rounds—about 1/16 inch thick. Thin slices ensure maximum crispness.
- Line the baking sheet with parchment paper. Arrange the sweet potato slices in a single layer, making sure they don’t overlap—crowding leads to soggy chips.
- Lightly brush each slice with olive oil using the silicone brush. This helps with browning and crisping. Sprinkle with a pinch of salt and any spices you like—cinnamon, paprika, or chili powder work well.
- Place the tray in the oven and bake for 25-30 minutes. Keep an eye on them from the 20-minute mark. They should turn a golden, slightly darker edge—crisp and fragrant. If edges brown too quickly, tent with foil.
- Once baked, turn off the oven and let the chips sit inside for an additional 5 minutes. This final dry heat ensures they’re thoroughly crisp. They will feel firm and brittle when cooled.
- Transfer the chips to a cooling rack and let them rest for at least 10 minutes. This step allows excess moisture to escape, enhancing crunch. Serve once cooled and crispy.
Allow the chips to cool completely on a rack before serving. They should be dry, crispy, and aromatic. Store in an airtight container for up to 3 days for best crunch.
How to Know It’s Done
- Color: edges should be a deep golden brown without burning.
- Texture: chips feel firm and snap easily when broken.
- Appearance: no soggy or limp spots, uniform crispness across slices.

Pro tips for perfect sweet potato chips
- Boldly brush slices with oil → Thin, even coating helps chips crisp up uniformly.
- Boldly slice very thin → Use a mandoline for consistent, paper-thin slices that crackle beautifully.
- Boldly watch during baking → Turn off oven once edges turn deep golden to avoid over-browning.
- Boldly let chips rest on a rack → Cooling prevents sogginess and boosts that perfect crunch.
- Boldly experiment with spices → Sprinkle lightly and taste as you go to keep flavor balanced.
- Boldly check for doneness → Chips should be firm, not bendable, with a slight shimmer of oil.
Common mistakes and how to fix them
- FORGOT to check oven temperature → Always verify with an oven thermometer.
- DUMPED too much oil on slices → Use a light, even brush for crispness without greasiness.
- OVER-TORCHED edges → Reduce baking time or tent with foil if edges darken too fast.
- MISSED cooling step → Let chips rest on a rack for maximum crunch and dryness.
Quick fixes for perfect chips
- When chips burn quickly, splash a little water on the tray and quickly wipe—smoke fades fast.
- If chips stick, patch with a bit of parchment paper and gently slide them off during cooling.
- DUMPED too much oil? Shield with a paper towel before baking to absorb excess and crisp up.
- When slices curl unevenly, rescue with a quick spray of water and rearrange for even baking.
- Pantry swap: use sweet potato with parsnip for a milder, earthier crunch that shimmer in the oven.
Prep, store, and reheat tips
- You can slice the sweet potatoes a day ahead; keep the slices in an airtight container in the fridge to prevent drying out. They stay fresh for up to 24 hours with minimal color change.
- Bake the chips ahead of time and store them in an airtight container at room temperature. They remain crisp for about 2 days, but for the best crunch, enjoy within 24 hours.
- Reheat baked chips in a 180°C (350°F) oven for 5-7 minutes until warmed and crispy again. Keep an eye on them to avoid burning the edges—sniff for that smoky aroma, and listen for a gentle crackle.
- Chips can be frozen after baking—place in a single layer on a tray to freeze, then transfer to a zip-top bag. Reheat straight from freezer, adding 2-3 minutes to the warming time, until they shimmer with crispness.
