Ingredients
  

  • 2 ripe plantains yellow with plenty of dark spots
  • 1 tablespoon olive oil or another suitable cooking oil
  • ¼ teaspoon salt
  • ¼ teaspoon ground cinnamon optional for a sweet version
  • Pinch of black pepper optional for a savory version
  • 1 teaspoon brown sugar optional for extra caramelization

Equipment

  • Baking sheet
  • Parchment paper
  • Sharp knife
  • Cutting board
  • Mixing bowl
  • Small spatula or tongs
  • Measuring spoons

Method
 

  1. Preheat the oven: Set the oven to 400°F (200°C) and allow it to fully preheat.
  2. Prepare the plantains: Cut off both ends and make a shallow lengthwise cut through the skin. Peel each plantain carefully.
  3. Slice evenly: Cut the peeled plantains diagonally into slices about ½ inch thick. Keeping the pieces similar in thickness helps them cook evenly.
  4. Season the slices: Place the plantains in a mixing bowl. Add the olive oil and gently toss until the pieces are lightly coated. Add salt and cinnamon for a sweet version, or salt and black pepper for a savory version.
  5. Arrange on the baking sheet: Line the baking sheet with parchment paper and place the slices in a single layer. Leave a little space between the pieces so they can brown instead of steaming.
  6. Start baking: Place the baking sheet in the preheated oven and bake for about 15 minutes.
  7. Turn the plantains: Carefully flip each slice with a spatula or tongs so the other side can brown evenly.
  8. Finish baking: Return the pan to the oven and bake for another 8–12 minutes, or until the centers are tender and the edges are golden brown.
  9. Add brown sugar if desired: For sweeter baked plantains, sprinkle a small amount of brown sugar over the slices during the final few minutes rather than adding a heavy layer at the beginning.
  10. Check for doneness: The finished plantains should be soft in the center with browned, caramelized edges. If they need more color, bake for another 2–3 minutes while watching them closely.
  11. Serve warm: Let the plantains cool for a minute or two, then serve immediately as a side dish or with your favorite main course.

Notes

Choose ripe plantains: Yellow plantains with dark spots are best for a naturally sweet, tender result. Green plantains will be firmer and more starchy.
Do not overcrowd the pan: Space between the slices helps moisture escape and gives the edges a better roasted texture.
Watch added sugar: Brown sugar can darken quickly at 400°F, so adding it near the end gives you more control over caramelization.
Adjust seasoning: Cinnamon is a good choice for sweet plantains, while garlic powder, paprika, black pepper, or chili can work well for a savory version.
Check the texture, not just the timer: Oven temperatures, plantain size, ripeness, and slice thickness can all affect the cooking time.

Storage

Refrigerate: Store leftover baked plantains in an airtight container for up to 3 days.
Reheat: Reheat in a 350–400°F oven or air fryer until warmed through. The edges will usually become firmer than when freshly baked.

Nutrition

Nutrition will vary according to the size of the plantains and the amount of oil or sugar used.

Summary

These easy baked plantains are made by slicing ripe plantains, lightly coating them with oil and seasoning, and baking them at 400°F until the centers are tender and the edges are beautifully browned. This simple method shows how to cook plantains in the oven without deep-frying and works especially well for a quick side dish.
