Wash and thinly slice fingerling potatoes on thin setting using a mandoline slicer.

Cover a microwave-safe plate with parchment paper. Brush olive oil on parchment paper (do NOT toss potato chips with olive oil!). Place potatoes in a single layer on the plate, being sure their edges do not touch (otherwise, they will stick together!). Sprinkle with sea salt.

Place in microwave and heat on high for 2 and 1/2 to 3 minutes*. Watch them closely to be sure they do not get to brown.

Remove from microwave and serve! Repeat process until all potatoes are crispy and crunchy!
