Cut off both ends of the plantains and remove the skin.
Slice the plantains diagonally into pieces about ½ to 1 inch thick. Try to keep the slices roughly the same thickness so they cook evenly.
Add enough oil to a large skillet to come about halfway up the plantain slices. Heat over medium to medium-high heat.
Add the plantain slices to the hot oil in a single layer, making sure not to overcrowd the pan.
Fry for 2–3 minutes, until the bottoms are golden brown and caramelized.
Flip the plantains and fry for another 2–3 minutes, until golden brown.
Remove the fried plantains from the oil with a slotted spoon and place them on a paper towel-lined plate to drain any excess oil.
Serve warm.
