Tips to make the Perfect Sweet Potato Slices in Air fryer
1. Any sweet potato works even those that are not the best looking
2. Use seasonings of your choice and vary them.
3. Use extra virgin olive oil to toss them. In case you want zero-oil version, skip the oil and use water, aquafaba or veg broth to toss the seasonings in. But I highly recommend using some oil to spray.
4. Cut the slices of equal width so that they cook evenly together.
5. Remember to shake the basket once or twice during the cooking time. This dislodges slices that may stick together and also facilitate even cooking.
6. You can do a batch of upto 500 gm. or 1 lb. at one go.
Ingredients
2 purple or orange sweet potatoes about 1 lb. or 500 gm. cut into medium slices
2 tsp. extra virgin olive oil
1 tsp. Himalayan pink salt
1 tsp. Italian seasoning
½ tsp. cayenne or paprika
½ tsp. garlic powder
Instructions
Wash, peel and slice sweet potatoes into ½ inch or medium-sized slices.

Toss sweet potato rounds in a bowl with extra virgin olive oil and seasonings mentioned. Using your hands toss well to coat each slice evenly.

Zero-oil version: Skip the oil and use water, vegetable broth or aquafaba in its place with seasonings and toss.
For Air frying:
Preheat air fryer at 180C or 360F for 3minutes. Lay the marinated slices in the air fryer basket in a single layer.
I fit 2 sliced sweet potatoes at one go. Here I have used the purple ones. But you can use orange, white or a mix of all of them for pretty colours.

Air fry at 180C or 360F for about 12 minutes. Check for doneness. Shake the basket every 6 minutes.
Now if needed, air fry at 180C or 360F for another 6-8 minutes depending upon the thickness of your slices and their doneness.

Serve hot. These sweet potato rounds have crispy edges and are fluffy inside. Enjoy. You can make these with regular potato slices too like these air fryer potato slices. These make for a lovely vegetable side or serve on casseroles.
FAQ
You can easily air fry thin slices of potatoes, sweet potatoes and veggies to make chips or crisps. Air fry medium slices for a side or to serve on top of casseroles.
You don't need to soak sweet potatoes in water before air frying as they are not very high in starch.
Peel the skin and snip off the ends of the sweet potato. Then cut into ½ inch slices for medium slices. I generally go with eyeballing it.
You can store leftover for 3 days in refrigerator in an airtight container. Reheat in air fryer for 3 minutes at 200C or 400F till heated through and crispy.
