Preheating your oven to 375°F (190°C).

Peel the ripe plantains and slice them into uniform rounds or diagonal pieces, depending on your preference.

Line the baking sheet with parchment paper for easy cleanup.

Place the sliced plantains in a single layer on the prepared baking sheet, making sure to leave space between each piece.

Using the cooking spray, lightly coat the tops of the plantains with a thin layer of oil. Also use a basking brush to apply the oil evenly over the sliced plantains.

Optional Seasoning: For a savory twist, sprinkle the plantains with a pinch of sea salt before baking. Alternatively, for a hint of sweetness, dust them with a light sprinkle of ground cinnamon.

Transfer the baking sheet to the preheated oven and bake the plantains for 20-25 minutes, or until they are golden brown and tender. Be sure to check on them periodically to prevent burning.

Flip each piece of plantain and return back to the oven to bake for an additional 10 minutes.

Once the plantains are baked to perfection, remove them from the oven and allow them to cool slightly before serving.
