Củ khoai tây, known worldwide as the potato, is one of the most widely consumed root vegetables in human history. From humble beginnings in the Andes mountains of South America, it has traveled across continents and become a global staple. In Vietnam, as in many other countries, khoai tây is loved for its mild flavor, starchy richness, and ability to transform into countless delicious dishes.
What is Potato?
The potato (Solanum tuberosum) is a starchy tuber from the nightshade family, closely related to tomatoes, eggplants, and peppers. Its appearance varies: round or oval, with skin ranging from brown, yellow, red, to purple, and flesh that can be white, yellow, or even violet.
There are several common types:
-
Russet potatoes – high in starch, fluffy when cooked, ideal for baking and mashing.
-
Waxy potatoes – firm and moist, perfect for soups and salads.
-
Yellow and red potatoes – versatile, with a buttery flavor.
In Vietnam, khoai tây is often sold fresh in markets and supermarkets, used in both traditional dishes and modern recipes.

Leave the skin on for extra fiber and nutrients.
-
Soak cut potatoes in water before frying to reduce excess starch and make them crispier.
-
Do not overcook in soups – they may break apart and turn mushy.
-
Pair with herbs and spices – rosemary, garlic, dill, curry, or chili complement potatoes beautifully.

Choose the right potato type – starchy for mashing, waxy for boiling or salads.
