Ingredients for white sweet potato chips
Two ingredients plus a handful of seasonings transform humble white sweet potatoes into addictive, crispy chips—no deep fryer needed.
| Ingredient | Amount | Notes |
|---|---|---|
| White Sweet Potatoes 🍠 | 2 large | Firm, uniform size preferred |
| Avocado Oil 🫒 | ¼ cup | High smoke point for baking |
| Flaky Sea Salt 🧂 | 1 tbsp | Diamond Crystal preferred |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Smoked Paprika 🌶️ | ½ tsp | For subtle smoky flavor |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Cornstarch 🌾 | 1 tbsp | For extra crispiness |
| Parchment Paper 📄 | 1 sheet | Non-stick baking surface |
| Mandoline Slicer ✂️ | 1 whole | For even 1/16-inch slices |
| Baking Sheet 🍳 | 1 whole | Rimmed, light-colored |
The sweet potatoes are everything here. Look for firm, uniform white sweet potatoes—avoid any with soft spots or sprouts. The Mandoline slicer is non-negotiable for even thickness (1/16-inch slices), but if you don’t have one, a sharp knife and steady hand work. Trader Joe’s and Whole Foods carry excellent white sweet potatoes year-round. Pro tip: Soak your potatoes in cold water for 10 minutes before slicing to remove excess starch—this ensures maximum crispiness. I’ve tested this with both orange and white varieties, and white sweet potatoes have a lower moisture content, which is key for that perfect crunch.
No avocado oil? Light olive oil or refined coconut oil work just as well—the high smoke point is what matters. Skip the cornstarch? Your chips will still crisp up, but they’ll be slightly less shatteringly crisp. For seasoning swaps, garlic salt instead of powder cuts prep time in half, though fresh garlic powder adds more depth. Want extra flavor? Toss in 1/4 tsp of cayenne for a subtle kick or 1/2 tsp of onion powder for sweetness. The key is keeping the slices thin and the oil minimal—this isn’t a frying operation, it’s a baking hack. If your oven runs hot, reduce the temperature by 25°F to prevent burning.
These chips are best served immediately, but if you’ve got leftovers, reheat at 375°F for 3-5 minutes to restore that crispy magic. Store in an airtight container at room temperature for up to 3 days, though they’ll lose some crunch over time. For meal prep, bake a double batch and freeze half on a tray before transferring to a bag—reheat frozen chips straight from the freezer at 400°F for 5-7 minutes. The parchment paper is your friend here: line your baking sheet with it, and you’ll never scrub another pan again. These chips reheat beautifully, making them perfect for game day or snack attacks all week.
Why You'll Love This Recipe
- No Peel, No Stress: I swear by these—just slice, toss, bake. The white sweet potatoes stay firm enough to cut cleanly (no mushy centers), and they crisp up perfectly without needing to peel them first. Honestly, I’ve made chips from store-bought sweet potatoes before, and this is the only batch that didn’t turn out like sad, gummy fries.
- Smoky-Savory Magic: That smoked paprika and garlic powder combo? It’s the kind of flavor that makes you reach for seconds without even thinking. The avocado oil keeps them crispy while letting the spices sing—slightly sweet, with a warm, earthy kick that pairs with everything from guac to a cold beer.
- Game for Any Occasion: Between us, these are my go-to for game day, lazy Sundays, or when I need a snack that feels fancy but isn’t. They hold up in airtight containers for days (yes, really), so I’ll make a big batch and toss them in lunchboxes or use them as a crunchy topping for tacos or salads later in the week.
- Budget Crunch Savior: A single white sweet potato stretches to four servings of chips—way more than regular potatoes—and costs next to nothing. I buy them in bulk, and the oil and spices are pantry staples, so this is my secret weapon for feeding a crowd without breaking the bank. Plus, the leftovers? They disappear faster than I can say “more chips, please.”
Step-by-step instructions for ultra-crispy white sweet potato chips
Here's how to achieve that perfect balance of crispy edges and tender centers every time.
Prep and Slice the Sweet Potatoes for Even Cooking
Start by peeling the 2 large white sweet potatoes using a vegetable peeler. I like to cut them in half lengthwise first to remove the skin more easily. Then, using the mandoline slicer, cut each half into 1/16-inch thick slices. This uniform thickness ensures all chips cook at the same rate.
As you slice, arrange the chips on a clean kitchen towel to remove any excess moisture. The drier the chips, the crispier they'll turn out. I press down gently on each slice with another towel to absorb moisture—this step is crucial for preventing soggy chips. Work in batches if needed to keep the slices from sticking together.
Create the Seasoning Blend for Maximum Flavor
In a small bowl, whisk together the 1 tbsp cornstarch, 1 tsp garlic powder, 0.5 tsp smoked paprika, and 0.5 tsp ground black pepper. The cornstarch acts as a natural thickener that helps create that irresistible crunch. I use freshly ground spices here because they deliver the most vibrant flavor—you can tell the difference immediately.
Next, add the 2 large white sweet potato slices to the bowl and toss them gently but thoroughly with the seasoning mixture. You want every slice coated evenly, but don't press down too hard or you'll crush some of the delicate pieces. If you're working with a large batch, do this in stages so the chips don't start to absorb moisture from the air.
Arrange Chips on the Baking Sheet for Optimal Airflow
Line the baking sheet with the parchment paper, leaving a slight overhang on the sides for easy transfer. Arrange the seasoned sweet potato slices in a single layer, leaving about 1/4-inch between each piece. This spacing is key—it allows hot air to circulate freely around each chip, promoting even crisping on all sides.
Here's a pro tip: I like to arrange the chips in overlapping rows, slightly offset like bricks. This maximizes surface area exposure to the heat while still fitting as many as possible on the sheet. Avoid stacking or overlapping too much, or you'll end up with unevenly cooked chips.
Bake at High Heat for Maximum Crispiness
Preheat your oven to 425°F while you're arranging the chips. Once preheated, carefully transfer the baking sheet to the middle rack. Bake for 20-25 minutes, flipping the chips once after 15 minutes. This flip ensures both sides get that perfect golden-brown color and crisp texture.
Watch closely during the last 5 minutes of baking. You're looking for chips that are deep golden brown with just a few slightly lighter spots—these will crisp up completely as they cool. The chips should be crisp to the touch but not burned. If any pieces seem to be browning too quickly, remove them early and finish them on the stovetop if needed.
Season Immediately and Serve While Crisp
As soon as the chips come out of the oven, sprinkle them generously with the 1 tbsp flaky sea salt. The heat from the chips will make the salt melt slightly, creating little flavor bombs that enhance every bite. I like to do this while the chips are still warm so the salt adheres perfectly.
Let the chips cool for 2-3 minutes on the baking sheet before transferring them to a serving bowl. This brief cooling period helps set the crispness, but don't let them sit too long or they'll lose their crunch. Serve immediately while they're at their crispest, and enjoy with your favorite dips or as a standalone snack. The contrast of the crispy exterior with the slightly sweet, tender interior makes these chips truly special.
Pro Tips For Making White Sweet Potato Chips
- CRANK THE HEAT HIGH: White sweet potatoes need serious heat to crisp properly—think 375°F (190°C) minimum, not whatever your oven’s default setting is. I used to cook them at 350°F and ended up with sad, greasy chips that stuck to the tray. High heat = crispy edges in 15-20 minutes, not a soggy mess.
- SLICE EVENLY, THINLY: Use a mandoline if you’re brave, but if not, a sharp chef’s knife and a ruler work—aim for ⅛-inch slices, no thicker. I learned this after burning one batch where the outer edges were perfect but the centers stayed raw. Thin slices = even cooking, no guesswork.
- DON’T SKIP THE DRYING: Pat those slices very dry with paper towels before tossing in oil—wet chips steam instead of crisp. I was lazy once and skipped this, and my oven smelled like a sad, greasy science experiment. Dry = crispy. Wet = regret.
- SALT AFTER COOLING: Toss the chips with flaky sea salt after they’ve cooled for 2-3 minutes—this prevents them from getting soggy from moisture. I used to salt them hot, and they’d turn limp within minutes. Wait, then sprinkle like you mean it (about ½ teaspoon per batch).
Serving suggestions for this recipe
Dip Pairings
These sweet potato chips shine with cool, creamy dips that balance their natural sweetness. My go-to is spicy cashew cream—blend 1 cup raw cashews, 2 tbsp lemon juice, 1 tbsp maple syrup, and ½ tsp cayenne—for a velvety contrast.
For something lighter, try avocado lime dip: mash 1 ripe avocado with 2 tbsp Greek yogurt, 1 tbsp lime juice, and a pinch of salt. 🌿
Sweet Toppings
Enhance the natural sweetness with fruit-based toppings served alongside. Fresh mango slices or pineapple chunks add juicy brightness, while a sprinkle of toasted coconut flakes introduces tropical crunch.
For a decadent touch, drizzle with dark chocolate sauce (melt ½ cup dark chocolate with 1 tbsp coconut oil)—the rich cocoa pairs beautifully with the caramelized edges. 🍍
Savory Serving Ideas
Transform these chips into a savory snack platter by pairing with pickled vegetables like radishes or jalapeños. A smoky chipotle aioli (mix ½ cup mayo, 1 tbsp chipotle in adobo, and 1 tsp lime juice) adds heat and creaminess.
For a protein boost, serve with grilled shrimp skewers or spicy black bean dip—the contrast of textures makes every bite exciting. 🍤
Game Day Spread
Elevate your game day spread by arranging chips in a rustic wooden bowl surrounded by mini dipping stations. Set out small ramekins with buffalo blue cheese dip, salsa verde, and honey mustard for variety.
Add crudité sticks (carrots, celery) and warm pita chips to create a full snack board. The key is keeping dips chilled and chips warm—use a slow cooker on "warm" for dips to maintain temperature. ⚽
Meal Prep Hack
Prep these chips ahead for easy meal prep by baking a double batch and storing in airtight containers with parchment paper between layers. Reheat at 375°F for 3-5 minutes to restore crispiness.
Pack them in bento boxes with hummus, sliced bell peppers, and whole-grain crackers for a balanced lunch. They also make a great trail mix alternative—toss with dried cranberries and almonds for a sweet-savory crunch on the go. 📦
Presentation Tips
For restaurant-worthy presentation, serve chips on a slate board with edible flowers (like nasturtiums) and microgreens for color. Use small cast-iron skillets for individual servings to keep chips warm and crispy.
Garnish with crispy fried shallots or toasted sesame seeds for extra texture. A lemon wedge on the side lets guests squeeze fresh juice over their dips for a zesty kick. 🎨

Frequently asked questions
Why do white sweet potato chips turn out soggy?
Soggy chips usually happen from excess moisture or uneven baking. Always pat your 1/16-inch slices dry with a kitchen towel after slicing, and avoid overcrowding the baking sheet. The 425°F oven temperature is crucial—too low and they'll steam instead of crisp. For extra insurance, spread the chips in a single layer with 1/4-inch spacing between each.
Can I use regular sweet potatoes instead of white?
You can try, but white sweet potatoes have less moisture, which makes them crispier. Regular sweet potatoes contain more water, so they may turn out softer. If you must use them, slice extra thin (1/16-inch) and bake at 400°F for 15-20 minutes
How do I make these chips oil-free?
For an oil-free version, skip the avocado oil and toss the slices with 1 tbsp cornstarch instead. Arrange them on a parchment-lined baking sheet and bake at 425°F for 25-30 minutes, flipping once. The cornstarch helps create crispiness through caramelization, though the texture will be slightly different from oil-baked chips.
What’s the best way to store leftover chips?
Store in an airtight container at room temperature for up to 3 days, but they’ll lose crunch over time. For longer storage, freeze them on a tray first, then transfer to a bag. Reheat frozen chips at 400°F for 5-7 minutes to restore crispiness. Avoid refrigerating—condensation ruins the texture.
Can I air-fry these chips instead of baking?
Use the air fryer at 375°F for 8-10 minutes, shaking the basket every 2-3 minutes for even cooking. The air fryer works well but requires more attention to prevent burning. Start with a small batch to test your specific model, as cooking times vary by appliance.
