Onion is one of the oldest cultivated vegetables in our history, originating in central Asia from where it spread across the entire world. This vegetable quickly entered into the religious ceremonies of several ancient civilizations. This was most apparent in Egypt, where onions were symbols of eternity, endless life and were part of burial ceremonies. It was described several times by the Israelites in the Bible.
To grow onion microgreens you do not need to soak or rinse and drain seeds. Prepare your soil by getting it sufficiently moist but be careful not to overwater. Spread seeds evenly across the surface of the soil. The mini scallions that are produced are smaller than the seed so it is a good idea to sow onions more densely than other microgreens. After seeds are sown, cover for three to four days to allow seeds to germinate, and then uncover seeds and place under a grow light. Continue to water when need. Harvest when the look and the flavor is to your liking. It grows slowly but harvest should be ready in 14-21 days.
Onion sprouts are very delicate and crunchy. Ideal in sandwiches or wraps – they will give texture and a light onion taste. Very effective as a garnish.
