Air Fryer Sweet Potato Chips — crisp, addictive, and healthier than store-bought chips. This air fryer sweet potato chips recipe gives you golden, crunchy slices with minimal oil and maximum flavor. We recommend a mandoline for uniform slices (about 3/32″ thick) and a short soak and dry step to remove excess starch — that’s the secret to ultra-crisp chips.
Prep Time: 10 mins • Cook Time: 15 mins • Additional Time: 25 mins • Total Time: 50 mins • Servings: 4
Ingredients
- 1 (8 ounce) sweet potato (about 1 medium)
- 1 tablespoon canola oil (or avocado oil)
- 1/4 teaspoon sea salt
- 1/4 teaspoon freshly ground black pepper
- cooking spray (optional)
Directions
Step 1
Slice the sweet potato into uniform 1/16″ (≈3/32″ preferred) rounds using a mandoline. Place slices in a large bowl of cold water and soak 20 minutes to remove excess starch.
Step 2
Drain and pat the slices completely dry on paper towels or a clean dish towel. Return dry slices to a clean bowl.
Step 3
Toss the slices with canola oil, sea salt, and black pepper until evenly coated. Wipe any excess oil from the bowl.
Step 4
Preheat the air fryer to 350°F (175°C). Lightly spray the basket with cooking spray. Arrange slices in a single layer (work in batches to avoid overcrowding).
Step 5
Air fry 12–16 minutes, turning and rearranging every 4 minutes so chips crisp evenly. Watch closely in the final 2–3 minutes; remove golden chips with tongs as they finish so the rest don’t burn.
Step 6
Cool chips on a wire rack 5 minutes — they will crisp further. Store in an airtight container for up to 3 days.
Cook’s Note
If you don’t have a mandoline, use a very sharp knife and slice as thinly and uniformly as possible. For extra flavor, toss with smoked paprika, garlic powder, or a pinch of cayenne before air frying.
