Harvest Period

September 1 - October 1

Onions have long been identified as medicines in ancient cultures and have enjoyed a reputation as a health food. It is believed that onions originated in central Asia and were being cultivated there over 5000 years ago. Onions would have appealed to our ancestors as they were less perishable than other fresh plant foods, were easy to grow and transport, and could be dried for later use – all factors that continue to make the onion so appealing in the modern kitchen.   

What to Look For  

There are generally two types of large, globe-shaped onions – mild and storage. The former class includes those that are grown in warm weather climates and have characteristic mild or sweet tastes such as Vidalia. Storage onions are grown in cooler climates and are left to dry for several months after harvesting. They generally have a more pungent flavour and are usually named by their color: white, yellow or red. 

Any fresh onion is likely to be identified by a firmness that almost makes it seem to burst out of its dry, crisp, papery skin.


Cleaning and Preparation

To peel onions, first trim the ends and cut in half through the root. The skins will then peel off easily. Place half an onion face down on the cutting board and make a series of parallel cuts.  Rotate the onion 90 degrees and cut again across the grain several times.  The onion will fall apart in small dice.


Onions should be stored at room temperature in a well ventilated container away from bright light. They should last at least one month.  

To freeze, peel, chop or slice onions. No blanching is necessary.  Simply pack into freezer bags or containers and store for 3-6 months in the freezer.  

Nutritional Information  

Onions are very rich in chromium (a trace mineral that helps cells respond to insulin), vitamin C, folic acid, B6, B1 and quercitin. They are a good source of sulphides that may lower blood pressure and prevent heart disease.

The red colour in these onions derives from flavonoids called anthocyanidins.

How to Use  

Red onions tend to be medium to large in size and have a mild to sweet flavour. They are often consumed raw and added to salads for their colour. They may lose their redness when cooked.

Red onions are also great on cold sandwiches and warm ones, like hamburgers and grilled cheese. Red onions are also delicious grilled or lightly cooked and sautéed.
