Sweet potato chips made in an air fryer are a crunchy, satisfying alternative to mass-produced potato crisps. This recipe transforms thin slices of sweet potato into a crispy snack using just a tiny fraction of the oil needed for deep frying. Seasoned with simple spices, they offer a perfect balance of natural sweetness and savoury crunch that makes them ideal for healthy snacking.
Finding a snack that satisfies the craving for something crunchy without being loaded with empty calories is a constant challenge. Store-bought crisps are often fried in heavy oils and covered in artificial flavourings, leaving you feeling sluggish afterwards. This homemade air fryer version offers a clean swap that respects your health goals while still delivering that essential crispiness. Sweet potatoes are naturally packed with vitamins and fibre, giving this snack a great nutritional profile compared to standard white potatoes.
The secret to getting a genuinely crispy chip in the air fryer comes down to moisture control and slice thickness. Sweet potatoes contain a fair amount of natural starch and sugar, which can cause them to soften or burn quickly if not handled correctly. Slicing them uniformly thin ensures they cook at the exact same rate. A brief soak in cold water helps wash away surface starches, which is crucial if you want to avoid soggy results.

Slice the sweet potatoes into very thin, uniform rounds. Using a mandoline slicer is the easiest way to ensure they are all the same thickness.
Place the slices into a large bowl filled with cold water. Let them soak for about twenty minutes to draw out the excess starch.
Drain the water and transfer the slices to a clean kitchen towel or paper towels. Pat them completely dry. Any leftover moisture will steam the chips instead of crisping them.
Put the dry sweet potato slices back into a dry bowl. Drizzle the oil over them and toss thoroughly so every slice has a very thin coating.
Add the sea salt, black pepper, and your choice of spices like smoked paprika. Toss again to distribute the seasoning evenly.
Preheat your air fryer to 180 degrees Celsius for three minutes.
Place the seasoned slices into the air fryer basket. Try not to overcrowd the basket too much, though a slight overlap is fine as they will shrink while cooking.
Cook at 180 degrees Celsius for twelve to fifteen minutes. Shake the basket every four to five minutes to redistribute the chips and ensure even crisping.
Keep a close eye on them during the last few minutes as the natural sugars can cause them to brown quickly. Remove them once they look golden and feel firm. Let them cool for five minutes to reach full crispiness before serving.
This usually happens if the slices were not dried properly after soaking, or if the air fryer basket was packed too tightly. Moisture is the enemy of crispiness.
No, the skin adds extra nutrition and a rustic texture. Just make sure to scrub them well under running water before slicing.
These chips are best eaten fresh. If you have leftovers, store them in an airtight container, but you may need to pop them back in the air fryer for two minutes to crisp them up again.
This indicates uneven slicing. If some pieces are thicker than others, the thin ones will burn before the thick ones can crisp up.
You can, but a tiny amount of oil helps conduct the heat and gives the chips that familiar, satisfying crunch.
