An Onion is a food item in Survival 303.


An onion has a beige body with a long green shoot on top. They grow in groups of three. The plant is found on several different islands.

Onions can be eaten on their own or used in crafting fish rolls with herbs, sardines, and mackerel. The onion can also be planted in a small compost to grow more of its kind. Though onions are one of the more efficient foods to forage, providing more nutrition than berries or apples, they have limited usage outside of being eaten raw and don't compare to bread, so they are rare to see on farms. Even so, they are necessary to craft fish rolls, if a player wants to be fancy, and they make a good snack on the go. Also, 25 onions can be crafted with a crate into a crate of onions, for ease of shipping or storage.
