Ingredients for white sweet potato chips
Simple ingredients transform into crispy, golden sweet potato chips with restaurant-quality texture.
| Ingredient | Amount | Notes |
|---|---|---|
| White Sweet Potatoes 🍠 | 2 lbs | Medium-sized, peeled and sliced |
| Avocado Oil 🫒 | ¼ cup | High smoke point preferred |
| Sea Salt 🧂 | 1 ½ tsp | Fine grain preferred |
| Smoked Paprika 🌶️ | 1 tsp | For subtle smoky flavor |
| Garlic Powder 🧄 | ½ tsp | Freshly ground preferred |
| Baking Powder 🍞 | ¼ tsp | For crispiness enhancement |
| Cornstarch 🌾 | 1 tbsp | For extra crunch |
| Nutritional Yeast 🧀 | 1 tbsp | Optional for cheesy flavor |
The white sweet potatoes are the star—choose firm, evenly shaped tubers for consistent slicing. Trader Joe's or Whole Foods carry the best quality, but any grocery store's organic section works. Avoid sweet potatoes with soft spots or sprouts, as they won't slice evenly. Peeled and sliced paper-thin (about 1/16-inch), they caramelize beautifully during baking. For the oil, avocado oil has the highest smoke point, ensuring even crispiness without burning. Store-bought oils like Mazola or Crisco work too if you're in a pinch.
No avocado oil? Grapeseed or light olive oil are excellent substitutes, though they may impart a slight flavor. Skipping the smoked paprika? Regular paprika or chili powder adds warmth instead. The cornstarch is non-negotiable for that signature crunch—it coats the slices and prevents sogginess. For a tangy kick, swap nutritional yeast for lemon zest or lime juice. Pre-sliced sweet potatoes? Slice them yourself—mandoline or sharp knife works best. The baking powder might seem odd, but it reacts with moisture to create an extra crispy exterior.
These chips stay crispy for 3-4 days in an airtight container at room temperature, or up to 2 weeks in the freezer. To revive stale chips, pop them in a 350°F oven for 3-5 minutes. For meal prep, bake extra batches and store in portions—perfect for snacking or adding to salads. Avoid stacking chips directly; use parchment paper between layers to maintain crispness. Season lightly before serving, as the chips intensify in flavor after baking.

Step-by-step instructions for white sweet potato chips
Transforming these vibrant tubers into delicate, crispy chips requires precision timing and technique.
Prepare the Sweet Potatoes for Even Slicing
Start by peeling the 2 lbs white sweet potatoes using a mandoline or sharp knife set to ⅛-inch thickness. I use a mandoline for consistency—each slice should be uniform to ensure even cooking. If using a knife, wrap the potato in plastic wrap first to prevent slipping, and work slowly for precision.
Arrange the slices on paper towels and pat them completely dry with another paper towel. Any moisture left on the slices will prevent proper crisping. The drier the slices, the crunchier your final chips will be. Spread them in a single layer and let them air-dry for 10 minutes while you prepare the seasoning mixture.
Create the Seasoning Blend
In a small bowl, whisk together the 1.5 tsp sea salt, 1 tsp smoked paprika, 0.5 tsp garlic powder, 0.25 tsp baking powder, 1 tbsp cornstarch, and 1 tbsp nutritional yeast. The baking powder and cornstarch work together to create that signature crispy texture, while the nutritional yeast adds a subtle cheesy depth that pairs beautifully with the sweetness of the potatoes.
I like to use my fingers to mix this dry blend thoroughly—it helps distribute the finer particles evenly. If you prefer, you can sift the ingredients through a fine-mesh strainer to eliminate any lumps before tossing with the potato slices.
Season and Arrange for Perfect Crisping
Working in batches, toss the dried potato slices with the seasoning blend until they're evenly coated. Place them in a single layer on parchment-lined baking sheets, ensuring they don't overlap. Overlapping slices will steam rather than crisp. I use two baking sheets at once to maximize space—this prevents crowding and ensures even air circulation.
Lightly brush both sides of each slice with 0.25 cup avocado oil using a pastry brush or your fingers. The oil should coat the slices lightly but not pool. This high-smoke-point oil ensures a crisp finish without burning. Arrange the sheets in the fridge for 15 minutes while you preheat the oven to 400°F.
Bake to Crispy Perfection
Place the baking sheets in the preheated oven and bake for 10-12 minutes, flipping the slices halfway through using a thin spatula. You'll know they're done when they're deep golden brown and crisp to the touch. The edges should be slightly darker than the centers, indicating even cooking.
Remove the chips from the oven immediately and transfer them to a wire rack to cool for 5 minutes. This cooling step is crucial—it prevents them from softening in the pan. Serve warm for maximum crunch, or store in an airtight container for up to 3 days if you prefer them at room temperature.
Pro Tips For Making White Sweet Potato Chips
- Slice Thin, Even Strips: Use a mandoline or sharp knife to cut the potatoes into 1/8-inch slices—no thicker or they’ll turn gummy. I learned this the hard way after burning three batches of uneven chips. For extra control, freeze the slices for 30 minutes before frying to prevent curling.
- Preheat Oil to 350°F: Too hot, and they burn before crisping. Too cool, and they absorb oil like a sponge. 350°F is the sweet spot—test with a pinch of potato: if it sizzles and floats, it’s ready. (Yes, even if you’re impatient like me.)
- Season After Frying: Sprinkle salt, smoked paprika, and garlic powder right as they come out of the oil, while they’re still sizzling. The heat helps the spices stick—dumping them in the bowl first just makes a dusty mess. Shake the bowl like you’re mad at it.
- Double-Fry for Crunch: Fry once at 350°F until soft (about 3 minutes), drain, then crank the oil to 375°F and fry again for 1-2 minutes. This two-step method guarantees a crisp exterior without a starchy interior. Sounds weird, but it works.
Perfect pairings for this white sweet potato chips
Dip Pairings
These sweet potato chips pair beautifully with rich, creamy dips that balance their natural sweetness. My go-to is a spicy cashew cream—blend 1 cup raw cashews, ½ cup water, 1 tbsp lemon juice, ½ tsp cayenne, and ½ tsp sea salt until smooth.
The creaminess contrasts perfectly with the crispy texture. For something lighter, try avocado lime dip: mash 1 ripe avocado with 2 tbsp lime juice, 1 tbsp Greek yogurt, and a pinch of salt. The zesty tang cuts through the sweetness. 🥑
Protein Pairings
Turn these chips into a complete snack by pairing them with protein-rich toppings. Sprinkle crumbled feta cheese or shredded rotisserie chicken over the chips for a savory crunch.
I love adding spiced chickpeas—toss cooked chickpeas with 1 tsp smoked paprika, ½ tsp cumin, and 1 tbsp olive oil, then bake at 400°F for 15 minutes. The protein keeps you full, while the chips add that satisfying crunch.
Sweet Pairings
For a dessert-like treat, pair these chips with sweet accompaniments. A drizzle of dark chocolate (melt 2 oz 70% dark chocolate and drizzle over warm chips) adds a luxurious finish. Or try honey mustard—mix 2 tbsp honey with 1 tbsp Dijon mustard and a pinch of salt.
The sweetness of the honey enhances the natural sweetness of the chips, creating a delightful contrast. Perfect for a sweet tooth craving! 🍯
Drink Pairings
Cool beverages balance the richness of these chips. A sparkling citrus spritzer—mix ½ cup sparkling water with 2 tbsp fresh orange juice and a splash of soda—cleanses the palate.
For something stronger, sip on an iced matcha latte (whisk 1 tsp matcha powder with ½ cup hot water, then add ½ cup cold milk and ice). The earthy notes of matcha complement the smoky seasoning on the chips beautifully.
Mealtime Pairings
Use these chips as a side dish to elevate any meal. Serve them alongside grilled shrimp tacos for a crunchy contrast to the tender protein. They also work well with charcuterie boards—pair with cured meats, cheeses, and fresh fruit for a balanced snack spread.
For a vegetarian option, serve with hummus and roasted veggies—the chips add a satisfying crunch to the soft textures. 🍽️

Frequently asked questions
Why do my sweet potato chips turn out soggy instead of crispy?
Soggy chips usually happen when moisture isn't properly removed before baking. Always pat slices completely dry with paper towels and let them air-dry for 10 minutes before seasoning. Also, avoid overcrowding on baking sheets—leave ½-inch space between slices for proper air circulation. The cornstarch in the seasoning blend helps absorb any remaining moisture too.
Can I make these chips without oil for a healthier version?
Yes! For oil-free chips, skip the brushing step and increase the cornstarch to 2 tablespoons in your seasoning blend. This creates a light coating that promotes crispiness through baking alone. Bake at 425°F for 12-15 minutes (2 minutes longer than oiled version) and flip once. The texture will be slightly less crisp but still satisfying.
What's the best way to store leftover sweet potato chips?
Store chips in an airtight container at room temperature for 3-4 days—they'll lose crispness faster than store-bought chips. For longer storage, freeze them in a single layer on parchment paper for 1 hour, then transfer to a freezer bag for up to 2 weeks. To revive, bake at 350°F for 3-5 minutes until crisp again. Never store them in the fridge—condensation makes them soggy.
How do I adjust this recipe for spicier chips?
Add ½ teaspoon cayenne pepper or 1 teaspoon chili powder to the seasoning blend for mild heat. For extra spicy chips, toss baked chips with 1 teaspoon hot sauce or sprinkle with ½ teaspoon red pepper flakes right before serving. Pro tip: Pair with cooling dips like yogurt or avocado to balance the heat.
Can I use regular sweet potatoes instead of white sweet potatoes?
Regular sweet potatoes work, but they'll be slightly darker and have a different texture. White sweet potatoes have a creamier, less fibrous interior that crisps more evenly. If using regular sweet potatoes, reduce baking time by 1-2 minutes and check for doneness at 9 minutes—they brown faster. The flavor difference is subtle but noticeable.
