Ingredients for white sweet potato chips
Six ingredients transform humble sweet potatoes into addictive, crispy chips in minutes—no oil needed.
| Ingredient | Amount | Notes |
|---|---|---|
| White Sweet Potatoes 🍠 | 2 lbs | Organic preferred, peeled |
| Kosher Salt 🧂 | 1 ½ tsp | Fine grain preferred |
| Smoked Paprika 🌶️ | 1 tsp | Optional for extra flavor |
| Garlic Powder 🧄 | ½ tsp | For savory twist |
| Cinnamon Sugar 🍯 | 2 tsp | Mix 1 tsp cinnamon + 1 tsp sugar |
| Avocado Oil Spray 🫒 | 1 tbsp | Light spray only |
| Cornstarch 🌾 | 1 tbsp | For extra crispiness |
The white sweet potatoes are the star—organic varieties from Whole Foods or your local farmers market have the best texture. Look for firm, unblemished tubers—avoid any with soft spots. If you can't find white sweet potatoes, regular sweet potatoes work too (just expect slightly deeper color). For the crispiest results, peel them first—the skin can burn before the flesh crisps. I usually grab a 2-pound bag for about 4 servings, but adjust based on how many you're feeding. Pro tip: let them sit at room temperature for 30 minutes before slicing—they'll crisp better.
Salt is non-negotiable for flavor, but Diamond Crystal kosher salt dissolves better than table salt. Want extra flavor? Mix your own seasoning—try smoked paprika for smoky depth or garlic powder for a savory kick. No air fryer? Use an oven at 400°F with a wire rack instead, but expect slightly less crispiness. The avocado oil spray is optional but helps with browning—lightly coat the chips before air frying. For the sweet version, cinnamon sugar is a game-changer (just mix equal parts cinnamon and sugar). If you're short on time, skip the cornstarch, but it adds that restaurant-quality crunch.
Store the chips in an airtight container with parchment paper between layers—they stay crispy for 2-3 days at room temperature. For longer storage, freeze them for up to 1 month (thaw at room temp before eating). I always make extra—they disappear fast. Want to reheat? Toss them back in the air fryer for 1-2 minutes at 350°F until crispy again. These chips freeze beautifully too, making them perfect for meal prep—just portion them into single-serving bags before freezing.

- No-Peel Needed: I swear by this trick—just scrub those white sweet potatoes, slice them thin, and skip the peeling. The skin stays on, adding a subtle earthiness that’s actually better than store-bought chips. (Yes, even my picky husband agrees.)
- Sweet & Smoky Magic: That cinnamon sugar coating? It’s the star. The first bite hits with a warm, almost caramelized sweetness, then the smoked paprika kicks in with a deep, cozy smokiness. Honestly, I’ve made these for movie nights and they disappear faster than popcorn.

Step-by-step instructions for crispy white sweet potato chips
Transform humble sweet potatoes into addictively crispy chips—no frying required!
🍳 Step 1: Prep and Season the Sweet Potatoes
Peel the 2 lbs white sweet potatoes using a vegetable peeler or sharp knife, removing all skin. Cut them into ⅛-inch thick slices using a mandoline or sharp chef's knife for even thickness. The thinner the slices, the crispier the final chips.
Pat the slices completely dry with paper towels—this is crucial for crispiness. Arrange them in a single layer on a baking sheet and lightly spray with the 1 tbsp avocado oil spray. Toss gently to coat evenly, then let them sit for 5 minutes to absorb the oil.
In a small bowl, mix together the 1.5 tsp kosher salt, 1 tsp smoked paprika, 0.5 tsp garlic powder, and 2 tsp cinnamon sugar. Sprinkle this evenly over the sweet potato slices, pressing gently to adhere. The spices will infuse as they crisp, creating a perfect balance of sweet, smoky, and savory flavors.
🔥 Step 2: Air-Crisp the Chips to Perfection
Preheat your air fryer to 380°F—this temperature ensures maximum crispiness without burning. Arrange the seasoned sweet potato slices in a single layer in the air fryer basket, leaving ½-inch gaps between each piece for proper air circulation.
Cook for 8-10 minutes, shaking the basket every 2 minutes to ensure even browning. You're looking for chips that are deep golden brown with crisp edges. The exact time depends on your air fryer model, so watch closely—sweet potatoes crisp faster than regular potatoes.
If you don't have an air fryer, use the oven's broiler function on high heat with the rack positioned 4 inches from the heat source. Broil for 5-7 minutes, checking frequently to prevent burning. The oven method requires more attention but yields equally crisp results.
🥘 Step 3: Add Cornstarch for Extra Crunch
While the chips are still hot, transfer them to a large bowl. Sprinkle the 1 tbsp cornstarch over the top and toss gently with a silicone spatula. The cornstarch acts like a magical crispiness booster—it absorbs moisture and creates an irresistible crunch.
Let the chips rest for 3-5 minutes before serving. This brief resting period allows the cornstarch to fully adhere and the flavors to meld together. Serve immediately while they're at their crispest, or store in an airtight container for up to 3 days—though they won't last that long!
⏰ Step 4: Serve with Dipping Sauces (Optional)
These chips are delicious on their own, but they're even better with a side of spicy mayo, honey mustard, or sweet chili sauce. The smoky-sweet flavor profile pairs perfectly with tangy or creamy dips. For an extra-special touch, sprinkle with additional cinnamon sugar right before serving.
Here's the thing—these chips are so addictive that you might find yourself eating them straight from the bowl. I've tested this recipe countless times, and every batch disappears faster than you can say "zero oil." The secret lies in that perfect balance of seasoning and texture—crispy outside, tender inside, with just the right amount of sweetness to keep you coming back for more.
Pro Tips For Making White Sweet Potato Chips
- Slice Thin, Evenly: White sweet potatoes are dense—if your knife isn’t sharp, you’ll end up with uneven chips that cook at different rates. Use a mandoline set to 1/8-inch (yes, it’s worth the splurge) or hand-slice with a chef’s knife, pressing firmly for consistency. Thinner slices = crispier chips, but don’t go below 1/16-inch or they’ll burn before they crisp.
- Dry Them Twice: I learned this the hard way—wet chips splatter like crazy and steam instead of crisp. After slicing, pat them dry with paper towels, then spread them on a wire rack for 20 minutes. Let them air-dry completely before frying; this guarantees a crispy exterior every time.
- Skip the Overcrowding: Your oil’s temperature drops faster than a summer breeze when you pile chips in. Fry in batches—no more than half the pan’s capacity—so the oil stays hot and the chips cook evenly. Overcrowding = soggy, greasy chips that taste like regret.
- Season After Frying: Smoked paprika and cinnamon sugar are delicate flavors—if you toss them on before frying, they’ll burn to ash. Instead, salt the chips immediately after they come out of the oil (while they’re still hot), then transfer to a bowl and mix in the spices. The residual heat will make the seasoning stick like glue.
Regional styles of white sweet potato chips
Southern Smoky Style
In the South, sweet potato chips get a smoky, spicy twist that’s perfect for game day. Start with the same base recipe, but boost the seasoning to 2 tsp smoked paprika and 1 tsp cayenne pepper for heat.
Add ½ tsp ground cumin for depth, and finish with a sprinkle of crushed red pepper flakes before air-frying. Serve with a side of cool ranch or chipotle mayo for dipping. This version is a crowd-pleaser at tailgates—just like the chips you’d find at a Southern BBQ joint. 🌶️
Mexican Fiesta Version
Transform your chips into a fiesta-worthy snack by mixing 1 tsp chili powder, ½ tsp garlic powder, and ½ tsp onion powder with the cinnamon sugar. For extra flair, toss the cooked chips in ¼ cup lime zest and a pinch of salt after air-frying.
Serve with a side of salsa verde or queso dip for a taste of Mexico. This variation is perfect for Taco Tuesday or Cinco de Mayo celebrations. 🌮
Asian-Inspired Sesame
For an Asian-inspired twist, skip the cinnamon sugar and season the chips with 1 tsp toasted sesame oil (instead of avocado oil) and ½ tsp ground ginger. After air-frying, toss the chips in 1 tbsp toasted sesame seeds and a pinch of white pepper.
Serve with a side of soy-ginger dipping sauce (mix 2 tbsp soy sauce, 1 tbsp honey, and 1 tsp grated ginger). This fusion version brings a nutty, umami-rich flavor that’s totally unexpected but incredibly delicious. 🥢
Sweet & Spicy BBQ
Combine the best of sweet and smoky with a BBQ-inspired seasoning. Mix 1 tsp smoked paprika, ½ tsp garlic powder, ½ tsp onion powder, and ½ tsp brown sugar before air-frying.
After cooking, toss the chips in 1 tbsp BBQ seasoning (like Montana BBQ Rub) and a drizzle of honey. Serve with a side of cool BBQ sauce for dipping. This version tastes like a cross between chips and BBQ ribs—pure indulgence! 🔥
Classic Cinnamon Sugar
Stick to the original recipe but double down on the sweetness. Use 3 tsp cinnamon sugar (mix 1.5 tsp cinnamon and 1.5 tsp sugar) for a more pronounced caramelized flavor. After air-frying, sprinkle with an extra ½ tsp cinnamon for a snowy finish.
This classic version is perfect for dessert-like snacks or pairing with coffee or tea. It’s like eating a sweet potato donut—crispy, sweet, and totally addictive. 🍯

Frequently asked questions
Why do my sweet potato chips turn out soggy instead of crispy?
Soggy chips usually mean moisture didn't evaporate properly. Always pat slices completely dry with paper towels before cooking, and avoid overcrowding the air fryer basket. Cook in single layers with ½-inch gaps between chips for proper airflow. If using an oven, broil on high heat with the rack positioned 4 inches from the heat source for maximum crispiness.
Can I make these chips without an air fryer?
Use your oven's broiler function on high heat with the rack 4 inches from the heat source. Arrange slices in a single layer on a baking sheet and broil for 5-7 minutes, checking frequently to prevent burning. For extra crispiness, lightly spray with avocado oil before broiling. The oven method takes slightly more attention but yields great results.
How do I store leftover chips to keep them crispy?
Store chips in an airtight container with parchment paper between layers to prevent moisture buildup. They'll stay crispy for 2-3 days at room temperature. For longer storage, freeze them for up to 1 month—just thaw at room temperature before eating. To reheat, toss back in the air fryer for 1-2 minutes at 350°F until crispy again.
What's the best way to slice sweet potatoes for crispy chips?
Use a mandoline slicer set to ⅛-inch thickness for the most even slices. If you don't have one, a sharp chef's knife works too—just be patient and steady. The thinner the slices, the crispier the final chips. For extra safety, wear cut-resistant gloves when using a mandoline. Pro tip: Let the sweet potatoes sit at room temperature for 30 minutes before slicing for better texture.
Can I use regular sweet potatoes instead of white sweet potatoes?
Yes, but expect slightly deeper color in the final chips. White sweet potatoes have a creamier texture and milder flavor, but regular sweet potatoes work perfectly fine. Just be aware they may develop a slightly darker hue when cooked. The crispiness and seasoning will still be excellent—this is more about personal preference than functionality.
