Onion Microgreens are easy to grow and very rich in flavor and nutrients.

It only takes a couple of greens on a sandwich or salad to taste the flavor! So, it’s best to start tasting small amounts to gauge how strong they are!

Onion microgreens smell strongly of onions, but they never make your eyes water or taste buds burn, even when chopped! Instead, chopping them up creates a beautiful aroma when added to a salad, burger, or steak.

The finished microgreen is a long, slender green similar to miniature chives. You can use micro-onions as an onion bulb substitute for many dishes — fantastic on hamburgers, salads, soups, garnishes, and more.

A small amount of onion microgreens goes a long way, so don’t use them too heavily at first.

White onion microgreen seed may produce more than one onion.

Harvest onion microgreens when they reach a height of 2 1/2- to 4 inches.

Onion microgreens will re-grow after harvest! You can get at least two or three cuttings.

The thin green stem will more than not have the remains of the black seed resting at the tip. The seed pod isn’t much of an issue when cooking. If it bothers you, rinse them off with running water.

Onions microgreens are ready to harvest between 11 and 15 days after sowing the seeds.

Seed Density

Seeding Density for Onion Microgreen Seed

By Weight

Home Microgreens Tray: 3.0 grams

1010 Tray: 8.0 grams

1020 Tray: 16 grams

Home Microgreens Tray: 1.2 teaspoons

1010 Tray: 3.2 teaspoons

1020 Tray: 6.3 teaspoons

All volumetric measurements are level, not heaping spoons.

I use these vertical-sided measuring spoons because the seeds are easier to level with the straight sides.

These are my recommended seeding densities to produce a great-looking tray of Onion microgreens. 

I like to allow microgreen leaves to develop to a larger size as they provide more nutrition & flavor than producing smaller leaves and stems.

Microgreen density depends on many environmental factors and seed germination percentages.

You may prefer to modify the seeding density, but my seeding densities are a great starting point if nothing else.
