Sweet potato chips baked in the oven might sound simple, but there’s a surprising depth to their flavor and crunch that keeps me coming back. Unlike fried chips, these are lighter, and the natural sugars caramelize beautifully, giving you that smoky-sweet bite without the greasy mess.
I started making these as a way to satisfy my snack cravings without overdoing it on oil or salt. The process is honest—just thin slices, a little oil, and patience in the oven. Watching them turn from pale to golden with crisp edges is almost meditative, and the aroma that drifts through the kitchen? Pure comfort.
What really makes this recipe stick with me is how adaptable it is. You can toss in a pinch of cinnamon, a sprinkle of paprika, or even a dash of chili powder. It’s a humble snack that feels special, perfect for those evenings when you want something warm, crunchy, and a little bit sweet.
This recipe focuses on the surprisingly addictive aspect of sweet potato chips that are baked, not fried, making them a healthier yet still deeply satisfying snack. I love how the natural sweetness of the potatoes caramelizes in the oven, creating a crispy edge with a slightly smoky flavor that’s perfect for binge-watching or sharing.
The story behind this recipe
- This recipe came about one lazy weekend when I found a bag of sweet potatoes lurking in the back of the pantry. I was craving something crunchy, but not fried, and the idea of baking thin slices just clicked. It’s funny how a simple snack can turn into a little ritual, especially when I want something satisfying without the fuss of deep frying.
- I remember the first batch I made—watching those slices turn from pale to golden, edges curling up like tiny chips, that smell of caramelized sugars filling the air. It felt like a small act of rebellion, choosing wholesome over greasy, and still ending up with something totally addictive. Now, it’s become my go-to for a quick, wholesome snack that actually feels indulgent.

Key ingredients and tips
- Sweet potatoes: I prefer the orange variety for their natural sweetness and vibrant color, but you can try different types for varied flavor profiles.
- Olive oil: Just a light coating helps the chips crisp up; too much, and they can turn greasy. Use a good quality, neutral oil if possible.
- Salt: I like finishing with flaky sea salt for that satisfying crunch and burst of saltiness, but seasoned salts or chili flakes work well if you want a flavor twist.
- Optional spices: A pinch of smoked paprika or cinnamon adds warmth and depth—start small and adjust to taste.
- Sugar or honey: A tiny drizzle can enhance caramelization, but be cautious—too much and the chips might burn quickly, creating a bitter edge.
- Lemon juice: A splash before baking brightens the natural sweetness and adds a subtle zing—don’t skip it if you want a fresh, lively flavor.
- Parchment paper: Lining your baking sheet prevents sticking and makes cleanup easier, especially since the sugars can caramelize fiercely.

- Baking sheet: To hold the chips during baking, ensuring they lay flat.

Step-by-step guide to baked sweet potato chips
- Preheat your oven to 200°C (390°F). Line a baking sheet with parchment paper to prevent sticking and make cleanup easier.
- Wash and scrub 2 large sweet potatoes thoroughly. No need to peel unless you prefer them that way.
- Slice the sweet potatoes very thin, about 1/16 inch (1.5 mm), using a mandoline or a sharp knife. Uniform slices ensure even baking.
- Place the slices in a large bowl. Drizzle with 1-2 tablespoons of olive oil, tossing gently to coat each piece evenly.
- Sprinkle with about 1 teaspoon of sea salt, and add optional spices like paprika or cinnamon if desired. Toss again.
- Arrange the slices in a single layer on the prepared baking sheet, not overlapping. Use tongs or a fork to handle the slices without breaking them.
- Bake in the preheated oven for 15-20 minutes. Keep an eye on them after 10 minutes to prevent burning.
- After 10 minutes, check the color and edges. They should be golden and crispy at the edges, with a slight bend. If not, continue baking in 2-minute intervals.
- Flip the chips carefully with a spatula at the halfway point for even crisping. Watch for bubbling and crackling sounds as a sign of readiness.
- Once crispy and golden, remove from the oven. Let them rest on the baking sheet for 2-3 minutes to firm up.
- Transfer to a wire rack or plate. If they cool too long on the sheet, they might lose some crispness.
- Serve immediately or store in an airtight container once cooled completely. Reheat in a 180°C (350°F) oven for 5 minutes if needed.
Allow chips to cool on a wire rack for 2-3 minutes. Serve immediately for maximum crunch or store in a sealed container once fully cooled.
How to Know It’s Done
- Color: edges are deep golden brown, not pale or burnt.
- Texture: chips are crispy and snap when broken, not limp or chewy.
- Appearance: evenly baked, no soggy or undercooked spots.

Notes
Pro tips for perfect chips
- Thin slices are key → Use a mandoline for uniform, crispy chips.
- Even coating matters → Toss slices gently in oil to prevent soggy spots.
- Watch the edges → Remove chips as soon as they turn deep golden to avoid bitterness.
- Flip halfway → Turn chips at 10-minute mark for even crispness and color.
- Use parchment paper → Keeps chips from sticking and makes cleanup easier.
- Cool on a rack → Rest chips 2-3 minutes to retain maximum crunch.
- Adjust oven rack → Position in middle for even heat distribution and optimal crisping.
Common mistakes and how to fix them
- FORGOT to evenly slice → Thin, uniform slices ensure crisp chips.
- DUMPED sugar directly on potatoes → Mix sugar with oil for even caramelization.
- OVER-TORCHED edges → Remove chips at first golden edges to avoid bitterness.
- MISSED flipping halfway → Flip chips at 10 minutes for even browning.
Quick fixes and pantry swaps
- If chips burn quickly, lower oven temperature and watch closely during the last 5 minutes.
- When slices stick, line your baking sheet with parchment paper to prevent tearing and sticking.
- Splash a few drops of lemon juice on potatoes before slicing to prevent browning and add brightness.
- Patch uneven cooking by flipping chips halfway through baking for uniform crispness.
- Shield edges from over-torching by tenting with foil if they brown too fast, preserving flavor and crunch.
Prep, store, and reheat tips
- Slice sweet potatoes ahead of time; store in an airtight container in the fridge for up to 24 hours to keep them from browning and drying out.
- You can bake the chips a day in advance; store in a sealed container at room temperature for up to 2 days. Crispness may slightly diminish, but reheating helps.
- For longer storage, freeze cooled chips in a freezer-safe bag for up to a month. Reheat in a 180°C (350°F) oven until crispy again, about 5 minutes, watching for smoky edges.
- Reheating chips can sometimes soften them; to restore crunch, spread on a baking sheet and re-bake at 180°C (350°F) for 5 minutes or until crisp and fragrant.
