Sweet potato chips feel like a treat, but they’re surprisingly easy to make at home. With just a few pantry staples and a hot oven, you can get that crunchy, salty bite without deep-frying. The trick is thin slices, even heat, and a little patience.
These chips are great for snacking, topping salads, or serving with a dip. Once you make them, you’ll wonder why you ever bought a bag.
What Makes This Recipe So Good
- Crunch without the fryer: You get crisp, golden edges using only the oven.
- Simple ingredients: Just sweet potatoes, oil, and a few seasonings.
- Endlessly customizable: Go sweet, smoky, spicy, or herby your call.
- Better-for-you snack: Baked, not fried, with fiber and natural sweetness.
- Make-ahead friendly: They keep well and stay crisp with the right storage.
Ingredients
- 2 medium sweet potatoes, scrubbed (skin on or peeled)
- 2 tablespoons olive oil or avocado oil
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon black pepper
- Optional spices: 1/2 teaspoon smoked paprika, garlic powder, chili powder, or cinnamon
How to Make It
- Preheat the oven: Set to 300°F (150°C) with racks in the upper and lower thirds. Line two large baking sheets with parchment for even browning and easy cleanup.
- Slice the sweet potatoes: Use a mandoline set to 1/16–1/8 inch (1.5–3 mm).If using a knife, take your time and keep slices as uniform as possible. Even thickness = even crisping.
- Dry the slices: Pat slices dry with paper towels. Removing surface moisture helps them crisp instead of steam.
- Season: Toss slices in a large bowl with oil, salt, pepper, and any optional spices. Coat lightly and evenly—no puddles of oil.
- Arrange on sheets: Lay slices in a single layer with no overlap.Crowding leads to soft chips.
- Bake low and slow: Bake 18–22 minutes, then rotate pans and flip the slices. Continue 15–25 minutes more, watching closely. They’re done when edges are deep golden and centers look mostly dry.
- Finish and crisp: Turn off the oven, crack the door, and let the chips sit inside 5–10 minutes.This gentle dry-out step boosts crunch.
- Cool completely: Transfer to a rack and let them cool. They crisp further as they cool. Taste and add a pinch of salt if needed.
Keeping It Fresh
- Cool before storing: Any warmth traps steam and softens chips.
- Store airtight: Use a sealed jar or container at room temperature for 3–4 days.
- Add a paper towel: A small piece inside the container absorbs extra moisture.
- Re-crisp if needed: Warm on a baking sheet at 275°F (135°C) for 5–7 minutes, then cool.
Benefits of This Recipe
- Less oil, more control: You decide the oil, salt, and seasonings.
- Nutrient-rich bite: Sweet potatoes bring fiber, vitamin A, and natural sweetness.
- Budget-friendly: A couple of potatoes make a big batch.
- Flexible for diets: Naturally gluten-free and easy to make vegan or Whole30-friendly.
What Not to Do
- Don’t slice thick: Thick slices stay chewy instead of crisp.
- Don’t crank the heat: High temps burn edges before centers dry.
- Don’t crowd the pan: Overlapping leads to soggy spots.
- Don’t skip the flip: Turning halfway helps them cook evenly.
- Don’t store warm: Steam inside the container ruins crunch fast.
Recipe Variations
- Smoky BBQ: Smoked paprika, garlic powder, onion powder, a pinch of brown sugar, and chili powder.
- Chili-Lime: Chili powder, cayenne to taste, and zest of 1 lime added after baking.
- Maple-Cinnamon: Light brush of maple syrup and a sprinkle of cinnamon before baking; finish with flaky salt.
- Herb and Sea Salt:</-strong> Dried thyme or rosemary with flaky sea salt; add fresh herbs after baking.
- Everything Seasoning: Sesame seeds, poppy seeds, dried garlic, dried onion, and salt.
FAQ
How do I slice without a mandoline?
Use a sharp chef’s knife and aim for the thinnest, most even slices you can manage. Cut off a small piece to create a flat base so the potato sits steady, then slice carefully. Consistency matters more than absolute thinness.
Why are my chips still soft in the middle?
They’re either too thick, too oily, or baked too hot. Keep the temp low, slice thinner, and use just enough oil to lightly coat. Let them rest in the turned-off oven and cool fully on a rack to finish crisping.
Can I make them without oil?
Yes, but they’ll be a bit drier and may brown unevenly. Lightly misting with water before seasoning can help spices stick. Watch the timing closely, as oil-free chips can go from done to overdone quickly.
What dips go well with sweet potato chips?
Try garlicky yogurt dip, sriracha mayo, guacamole, hummus, or a tangy lime crema. For sweet versions, pair with a cinnamon Greek yogurt or honeyed ricotta.
Can I use the convection setting?
Yes. Lower the temperature by about 25°F (15°C) and check earlier. Convection moves air efficiently, so chips can brown faster and more evenly.
Do I need to peel the sweet potatoes?
No. The skin adds texture and nutrients. If you prefer a smoother bite, peel them. Either way works.
