What is green onion salt?

Basically, green onion salt is an herb salt. You’re crushing sea salt into raw green onions and then drying them out to preserve that bite of fresh, green onion flavor.

It has a light, aromatic flavor. We like to use it to season our scrambled eggs as it gives the eggs a really nice flavor.

Scallions vs green onions vs spring onions

There are subtle differences between the three different plants and they typically refer to the age of the plant. For example, scallions have the thinnest whites, green onions are slightly thicker, and spring onions have a small bulb. (Source).

For this recipe, feel free to use any of these plants! The most important thing is to make sure your greens are still firm and healthy. We typically use our onions at the spring onion state for this recipe.

How do you make it?

First, you’ll need to gather your supplies. For us, this often means heading to the garden as we typically grow at least 100 onions a year. We eat many of them as spring onions (or green onions)! They’re delicious fresh, dried, or preserved in this delicious spring onion salt.

Ready to get started? Here’s all you need to do!

  1. Preheat your oven to its lowest temperature. This is typically 170 degrees Fahrenheit.
  2. Place your parchment paper or silicone liner on your baking tray.
  3. Rinse and dry the greens of 3-4 green onions. Remove any decaying or wilting sections.
  4. Remove the greens from the whites of the onions. Roughly cut your greens into 3 or 4 parts to fit into the food processor bowl.
  5. Pulse your green onions in your food processor until they turn into a paste. You may need to stop and stir occasionally.
  6. Add sea salt to the bowl. Pulse until completely distributed.
  7. Pour the green onion salt onto the tray and spread evenly. If using a baking dish, press it into the thinnest layer you can make.
  8. Place in the oven and allow to dehydrate until completely dry. Stir around every 30 minutes to an hour for even drying.
  9. Allow to cool and store in airtight jars.

How will I know when my herb salt is done?

There are several things to look for to tell when the salt is fully dry. It’s important to make sure the salt is completely dry so that you avoid any bacteria growth (although salt is naturally anti-bacterial) and to minimize clumping.

  • The color will turn to a lighter shade of green
  • You shouldn’t feel any moisture when you rub the salt between your fingers
  • You might notice sections of the salt starting to clump together

How long will green onion salt store?

Sine this spring onion salt is baked to dry, it should last about a year (if not longer)! How convenient is that? You can make one batch and come back to it again and again.

How can you preserve green onions?

There are several wonderful ways to preserve green onions! We like to dehydrate green onions to season soups and other recipes. This spring onion salt is such an easy to use up too many green onions, too. You can also make and freeze a spring onion pesto. We even like to slice up green onions and freeze them to use later!

This makes a great gift!

Although we love this lightly herby salt, it will take a time to use it all up. I recommend storing in 1/4 pint jars and giving it away! It’d be perfect to add to a housewarming basket.

Save some for zucchini season and sneak a jar onto your neighbor’s porch with a heap of squash. It’s a simple way to share some love with the people around you.
