Ingredients & Substitutions
Everything you need to make these sweet potato chips
Sweet potato: Swap with regular potatoes or parsnips for a different flavor and texture.
Olive oil: Avocado or light coconut oil work well as alternatives.
Thyme: Use dried rosemary or oregano if you prefer a different herb note.
Paprika: Smoked paprika adds depth; omit for a milder chip.

How to Make Air Fryer Sweet Potato Chips
Step 1. Slice the Sweet Potatoes
Rinse and peel a medium to large sweet potato. Slice into uniform 1/8″ thick rounds using a sharp knife or a mandoline for consistent results.
Step 2. Mix the Seasoning
In a medium bowl, combine 2 tablespoons olive oil with thyme, paprika, garlic powder, onion powder, salt, and a dash of pepper. Stir to blend the oil and spices into a cohesive coating.
Step 3. Coat the Sweet Potatoes
Place the sweet potato slices in the bowl and toss gently so each slice is evenly coated with the oil and seasoning mixture.
Step 4. Load the Air Fryer
Arrange the coated slices in a single layer across the air fryer basket. They may overlap slightly but should not be stacked. Air fry at 380°F (approx. 193°C) for 10 minutes.
Step 5. Check and Finish
After 10 minutes, remove the tray and discard any slices that are fully browned. Rearrange remaining slices for even cooking and air fry 2–3 more minutes until crisp. Transfer to a board to cool — they will firm up as they cool.
Expert Recipe Tips
Slice evenly: Consistent 1/8″ slices give the best, most even crisping — a mandoline helps.
Watch closely: Chips can go from perfectly crisp to burnt quickly, so check them near the end of cooking.
Cook in batches: For small air fryers, cook in batches to avoid overcrowding and ensure crisp results.
Serving Suggestions
- Dip: Serve with garlic aioli or Greek yogurt-based ranch.
- Topping: Use chips as a crunchy taco or salad garnish.
- Side: Pair with burgers or include on an appetizer platter.
- Breakfast: Add to a breakfast hash for extra texture.
Store airtight: Keep chips in an airtight container; they may soften overnight from moisture.
Re-crisp: Reheat in the air fryer 2–3 minutes to restore crunch before serving.
How do I ensure crispiness? Slice uniformly and avoid overcrowding the basket.
Can I bake them instead? Yes — bake at 400°F for 20–25 minutes, flipping once, until crisp.
Best slicer? A mandoline makes thin, even slices quickly; use a sharp knife if you don’t have one.
Different seasonings? Try chili powder, cumin, or a touch of cinnamon for a sweet-savory twist.
How long do they keep? Best the same day, but up to 2 days in an airtight container; re-crisp before serving.
