Ingredients for sweet potato kettle chips
Restaurant-quality crunch starts with these nine simple yet strategic ingredients for perfect kettle chips.
| Ingredient | Amount | Notes |
|---|---|---|
| Medium Sweet Potatoes 🍠 | 2 lbs | Organic preferred, skin-on for texture |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | Light variety for crispiness |
| Kosher Salt 🧂 | 2 tbsp | Diamond Crystal preferred |
| Smoked Paprika 🌶️ | 1 tbsp | For smoky flavor variation |
| Ground Cinnamon 🌿 | 1 tsp | For sweet variation |
| Garlic Powder 🧄 | 1 tsp | For savory depth |
| Lemon Zest 🍋 | 1 tsp | Freshly grated for zesty kick |
| Avocado Oil Spray 🫒 | 1 can | For kettle cooking |
| Cornstarch 🌾 | 1 tbsp | For extra crispiness |
Sweet potatoes are the foundation—organic varieties like Jewel or Beauregard work best, with their vibrant orange hue and naturally sweet flavor. Trader Joe's and Whole Foods carry excellent options, but any local farm stand will do. Avoid sweet potatoes with soft spots or green areas, as these indicate spoilage. For even slicing, use a mandoline slicer (or a sharp knife and steady hand)—thin, consistent slices are key to crispy results. The skin adds texture, so don't peel unless you prefer a smoother bite. If you can't find organic, conventional sweet potatoes work fine, just give them a thorough rinse before slicing.
No smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close. Want extra crispiness? Toss in 1 tbsp cornstarch with the olive oil before coating. The lemon zest can be swapped for 1/2 tsp citric acid if fresh isn't available, though the flavor won't be identical. For a spicy kick, add 1/2 tsp cayenne pepper to the salt mix. The avocado oil spray is non-negotiable—it has a high smoke point and won't leave residue like other oils. If you're short on time, pre-cut sweet potato slices from the produce section work, but they won't be as crispy.
Store prepped sweet potato slices in airtight containers with parchment paper between layers for up to 2 days in the fridge. For longer storage, freeze slices on a tray before transferring to a bag—cook straight from frozen for best texture. The finished chips keep their crunch for 3-4 days in an airtight container, though they're best enjoyed within 24 hours. For bulk prep, double the batch and freeze portions—perfect for game day or movie nights. Reheat in a 200°F oven for 5 minutes to restore crispiness if needed.

Step-by-step instructions for sweet potato kettle chips
Transform simple sweet potatoes into crispy, flavorful chips using just an air fryer.
👨🍳 Step 1: Prep and Slice the Sweet Potatoes
Wash the 2 lbs of medium sweet potatoes thoroughly to remove any dirt, then pat them completely dry with a clean kitchen towel. I use a mandoline slicer set to ⅛-inch thickness for even slices—this ensures crispiness without burning. For extra safety, wear cut-resistant gloves when slicing.
Arrange the slices on a clean kitchen towel and lightly dust both sides with the 1 tbsp cornstarch. This coating prevents sticking and promotes that perfect crunch. Let them sit for 5 minutes while you prepare the seasoning mix—this gives the cornstarch time to adhere fully.
👨🍳 Step 2: Create the Seasoning Blend
In a small bowl, combine the 2 tbsp kosher salt, 1 tbsp smoked paprika, 1 tsp ground cinnamon, 1 tsp garlic powder, and 1 tsp lemon zest. Mix thoroughly with a fork to ensure even distribution of flavors. This blend adds depth—smoky, sweet, and tangy all at once.
I like to add the seasoning right before air frying to prevent moisture loss. Keep the bowl nearby so you can toss the chips quickly after they come out of the air fryer. The lemon zest adds a bright contrast that balances the sweetness perfectly.
🔥 Step 3: Arrange and Pre-Cook the Chips
Lightly spray the air fryer basket with the avocado oil spray, then arrange the sweet potato slices in a single layer without overlapping. Use the basket's rack to create space between slices—this ensures even air circulation. For the first batch, I recommend cooking at 350°F for 8 minutes to start the drying process.
After 8 minutes, carefully remove the basket and shake it gently to separate any stuck slices. Return them to the air fryer for another 4 minutes at 375°F. This two-stage cooking prevents burning while ensuring maximum crispiness. You'll know they're ready when edges turn golden brown and centers still feel slightly soft.
🥘 Step 4: Season and Finish
Immediately after the second cook, transfer the hot chips to a large bowl. Add the seasoning blend and toss vigorously with tongs to coat every piece evenly. The residual heat helps the seasoning adhere perfectly. For extra crunch, I like to spread them on a wire rack for 2-3 minutes to let any excess moisture evaporate.
Serve immediately while still crispy—these chips lose their texture as they cool. For a restaurant-style presentation, arrange them on a platter with a sprinkle of extra lemon zest. The combination of smoky paprika, sweet cinnamon, and bright lemon creates a flavor profile that's both comforting and sophisticated.
⏰ Step 5: Batch Cooking for Full Yield
Repeat the process in batches, making sure not to overcrowd the air fryer basket. Each full load of 2 lbs sweet potatoes yields about 6-8 cups of chips, perfect for sharing. I find that cooking in two 10-minute sessions at 375°F works best for larger batches—this maintains consistent texture throughout.
For storage, let the chips cool completely, then transfer to an airtight container. They'll stay crispy for 3-4 days at room temperature, though I always find they disappear long before then. The key to perfect kettle chips is patience—don't rush the cooking or seasoning steps, and you'll achieve that ideal balance of crispy exterior and tender interior every time.
Pro Tips For Making Sweet Potato Kettle Chips
- Slice Thin, Slice Even: I learned this the hard way—uneven slices mean uneven cooking. Use a sharp mandoline or a steady hand with a knife to cut them 1/8-inch thick, no thicker. If you’re freehanding, wrap the potato in plastic first to grip it better.
- Toss Dry, Not Wet: Extra-virgin olive oil sticks better to dry potatoes. After slicing, pat them very dry with a towel, then toss in the oil and spices. Wet slices steam instead of crisp, and you’ll end up with sad, limp chips—no one wants that.
- Watch the Heat, Then Bake Low: Start at 425°F for 10 minutes to crisp the edges, then drop to 350°F for 20-25 minutes. High heat too long burns the outside before the center cooks; too low and they turn into sweet potato fries. The second temp is where magic happens.
- Salt Before Baking, Twice: Salt before baking (½ tsp per pound) lets it penetrate, and sprinkle another pinch halfway through. I know, it sounds excessive, but the flavor builds—especially with smoked paprika and cinnamon. Skip this, and your chips taste bland, even if they look perfect.

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
While you can technically make chips from regular potatoes, sweet potatoes bring a naturally sweet, vibrant flavor that pairs beautifully with the smoky and spicy seasonings. Regular potatoes tend to be starchy and less flavorful, though they'll still crisp up nicely. For best results, stick with sweet potatoes—their texture and taste make them ideal for this recipe.
Why did my chips turn out soggy instead of crispy? Soggy chips usually happen from uneven cooking or moisture buildup.
What’s the best way to store leftover chips?
Transfer cooled chips to an airtight container immediately to maintain crispiness. They’ll stay fresh for 3-4 days at room temperature, though I recommend eating them within 24 hours for the best texture. For longer storage, freeze slices on a tray before transferring to a bag—cook straight from frozen for best results. To revive stale chips, reheat at 200°F for 5 minutes.
Can I make these chips without an air fryer?
If you don’t have an air fryer, use a baking sheet with a wire rack. Arrange slices on the rack, spray lightly with oil, and bake at 400°F for 15-20 minutes, flipping halfway. For a stovetop method, pan-fry slices in a thin layer of oil over medium-high heat for 2-3 minutes per side until crispy. The kettle method is just a faster, more efficient alternative.
How can I make these chips spicier?
Boost the heat by adding ½ tsp cayenne pepper or 1 tsp chili powder to the seasoning mix. For extra kick, toss cooked chips with 1 tbsp hot sauce or sprinkle with crushed red pepper flakes right before serving. Pair with a cool dip like ranch or lime crema to balance the spice. Adjust to taste—start with less if you're sensitive to heat!
