Plantain vs Banana: What's the Difference?
Short answer: Plantains and bananas are both Musa, but plantains are larger, starchier, lower in sugar, and almost always cooked (fried, boiled, grilled), while dessert bananas are sweeter and eaten raw. A ripe plantain turns black and sweetens, but stays firmer and more savoury than a banana.
| 🍌 Plantain | 🍌 Banana | |

| Taste | Green plantain is starchy and neutral (potato territory); yellow turns tangy-sweet with body; black-ripe is dessert-sweet with banana perfume and caramel edges when fried. One fruit, a whole ripening menu. | Creamy, sweet, and mildly tangy with vanilla and clove-like aromatics; cooking bananas (Saba, plantains) are starchy and squash-like until caramelized by heat. |

Plantains and bananas both belong to the genus Musa, which is why they look like siblings on the shelf. The practical split is culinary, not botanical: a dessert banana (the familiar Cavendish) is bred to ripen soft and sweet and is eaten out of hand, while a plantain is a starchier cooking cultivar treated much more like a potato.
Green plantains are firm, dry, and starchy - perfect for frying into tostones or chips. As they ripen the skin goes yellow, then fully black, and the flesh sweetens and softens somewhat, good for sweet fried maduros. But even at their ripest, plantains hold their shape and stay more savoury than a banana, and they don’t develop the same soft, fragrant sweetness.
The quick tell at the store: plantains are usually bigger, more angular, thicker-skinned, and often sold while still green or blotchy, whereas dessert bananas are smaller, rounder-shouldered, and sold yellow. When in doubt, remember the rule of thumb - if you plan to eat it raw, buy a banana; if you plan to cook it, buy a plantain.
Frequently asked questions
Is a plantain just an unripe banana?
No. They're different cultivars of the same genus (Musa). Plantains are bred for cooking and stay starchy and firm even when ripe, whereas a dessert banana is bred to be sweet and soft when ripe. An unripe dessert banana is starchy too, but it isn't a plantain.
Can I eat a plantain raw?
You can, but it's usually unpleasant when green - dry, starchy, and astringent. Very ripe (black-skinned) plantains are sweeter and some people eat them raw, but plantains are almost always cooked.
Which is sweeter?
The dessert banana. Plantains contain more starch and less sugar, so even a fully ripe plantain tastes far less sweet than a banana.
