This week’s Vegetable Box Feature: Red Onion, also called Spanish onion or purple onion

Did you know?

  • They are crunchy, pungent, sweet, and slightly spicy when raw and when cooked their flavor lessens and grows mildly sweeter.
  • The intensity of the pungent flavor varies depending on age, particular variety, and the amount of sulfur in the growing soil or the fertilizer used.
  • They contain vitamin C, fiber, iron, and calcium. They also have a high polyphenol and flavonoid content, including a large amount of quercetin, which provides antioxidant properties that contribute to overall health, and sulfur, which promotes anti-inflammatory processes within the body.
  • They have more health benefits than white onions.
  • They are the most popular type of onions in India, the Mediterranean, and the Middle East, but in Britain white onion is the most common type.

Fun Fact:

  • Red onions have earned their “red” name because their purplish skins have historically been used to make reddish dyes.

How to Store It:
The bulbs will keep 1-2 months when stored in a cool, dry, and dark place with good air circulation. When sliced, red onions will keep 7-10 days when stored in a sealed container in the refrigerator.

How to Use It:
Red onions are best suited for both raw and cooked applications such as grilling, roasting, braising, caramelizing, and pickling. Red onions are milder in flavor compared to the other popular common onions including white and yellow, and are favored for their sweet flavor, used raw by chefs and home cooks on sandwiches, burgers, and salads.  The onions can also be chopped and tossed into leafy green salads, minced into salsa or guacamole, or pickled in red wine vinegar and layered on tacos, pizza, and fried rice. In addition to fresh preparations, red onions can be grilled for a smoky flavor.
