Peel the sweet potatoes, trim the ends, and slice them thinly into sticks.

Place the sweet potato sticks into a ziplock bag.

Add 2 pinches of salt and 3 tbsp of cooking oil into the bag.

Inflate the bag slightly and shake well to evenly coat the sweet potatoes.

Place a layer of kitchen paper on a plate and spread the sweet potato sticks evenly on top.

Microwave for 2 minutes.

Place another layer of kitchen paper on top, flip the sweet potatoes, and remove the bottom paper. Wipe off any moisture from the plate.

Microwave for another 2 minutes.
