Peel the plantains. Start by trimming the ends off of both plantains. Slice through the peel lengthwise, just deep enough to wedge your knife (or nails) under the peel. Pull the peel back to remove completely.
Slice the plantains. Using a sharp knife, slice the plantains into ⅛ inch thick slices.
Preheat the oven & prep a pan. Preheat the oven to 350 degrees Fahrenheit / 177 degrees Celcius. Line a sheet pan with parchment paper.
Season the plantains. Toss the plantains in a bowl with oil and salt until evenly coated. Spread them out on the parchment lined pan, making sure they don't overlap.
Bake until golden & crispy. Transfer the pan to the oven and bake for 15-20 minutes, or until they are golden and crispy. Note that they will continue to firm up while cooling. Enjoy!
