Cut off the top part and score the peel lengthwise to make it easier to peel them. Remove the peel.
Slice the plantain with a mandolin slicer for evenly sliced pieces.
Add olive oil and salt to the sliced plantains and mix it well until the plantain slices are coated evenly.
Place them on a baking tray lined with parchment paper, make sure that they are laying flat without touching each other. Bake them at 350°F/180°C for about 15 minutes until they are golden brown.
*Your plantains for chips should be a light green.Storage: I would recommend eating them fresh, on the same day. But if you make sure to bake them all the way through, let them cool off completely, and then store them in an air-tight jar at room temperature, they will be good for 1-2 days.
