How to Dehydrate Green Onions

Introduction

Green onions are a popular veggie in your kitchen with great nutritional value. It is a part of the Allium family, which consists of veggies like garlic, leeks, and shallots. Green onion is an amazing vegetable to add to your healthy diet. If you know how to dehydrate green Onions, you can easily preserve them for a longer time rather than keeping them in the fridge.

Green onions are a variety of onions, which are also known as spring onions, and grow to be small bulbs that never get to full-size onion bulbs. They have a similar flavor and texture to fresh green onions, but they are more concentrated and last longer.

Green onions can lose their flavor and taste easily when they are preserved in the fridge. So, wasting green onions may happen. If you learn how to dehydrate green onions, you will never ever waste any green onions again.

How to dehydrate green onions – Step-by-step guide

Dehydrating green onions is a step-by-step process that is used to preserve their flavor for later use. Here’s a basic guide on how to dehydrate green onions:

Step 1: Preparing the green onions for dehydrating

Preparing the green onions for dehydrating

First, wash the green onions with fresh water. Then, simply cut off the roots and chop the onion into pieces according to your choice. But the outer white portion is thicker than the inner green portion, so piece them in a suitable size as it is easy to dehydrate.

The piece size and shape are recommended to be kept the same as it takes the same amount of time to dehydrate.

Step 2: Place the green onions into the dehydrator

Now, place the sliced onions on the dehydrator trays. Keep the green part and white part of the onions separately. As the white portion is thicker than the green part, it will take longer to dehydrate. I collect the green part from the tray when it’s done. I prefer to keep the white portion of the onions longer time in the dehydrator, so it will automatically dehydrate.

Step 3: Start dehydrating

When you have done the two steps, you are ready to jump to start dehydrating. You can assume the green onions as vegetables or as an herb.

Vegetable: The favorable temperature for fresh vegetables like green onions is 125 degrees Fahrenheit. It may take 5-6 hours to dehydrate at this temperature.

Herb: As a spicy lover people, I like to use green vegetables as one of the main ingredients in my cooking, which is basically an herb. I prefer to dehydrate green onions at 100 degrees Fahrenheit for 7-9 hours as it is good to preserve their flavor, color, and taste.

How to dry green onions without the dehydrator

Drying green onions without a dehydrator is a simple process that can be done using common kitchen tools. Let’s have a look at how to dehydrate onions without a dehydrator:

Drying green onions in the oven is a quick and effective method. Here’s a step-by-step guide about how to dry green onions in the oven:

  • Wash the green onions thoroughly and pat them dry with a clean kitchen towel.
  • Then, trim off the roots.
  • Next, chop the green onions into small, even pieces. The size should be roughly one-fourth to one-half of an inch.
  • Set your oven on to the lowest temperature setting you can (125ºF/52ºC).
  • Place the prepared green onions on a baking sheet or tray and put it in the oven.

Note: If your oven doesn’t support 125ºF, then set the lowest temperature setting possible and keep the door of the oven slightly open. However, in this case you need to be extra careful and check regularly.

Dehydrating green onions using the Microwave

Step 1: Lay out the sliced green onions in a single layer on a microwave-safe plate. Make sure they are evenly distributed to ensure uniform drying.

Step 2: Set your microwave to a low power setting, such as 30-40%. Microwaving on low power helps prevent the onions from cooking completely and lets them gradually dry. Microwave the green onions in 1–2-minute intervals so that they will not over-drying. Stir or rearrange the onions on the plate between intervals to ensure even drying.

Step 3: Keep a close eye on the green onions as they dry. The length of time it takes to dry the green onions will be determined based on the microwave’s wattage and the amount of onions being dried. Typically, it may take 5-15 minutes. The green onions are ready when they are thoroughly dried and crispy but still retain their green color.

How to store dehydrated green onions

Storing dehydrated green onions properly is important to maintain their flavor and quality. Make sure the dehydrated green onions are cooled completely before storing. If they are still warm, condensation can form in the storage container, leading to spoilage.

  • Soak the green onions in warm water for 10 minutes. Time may vary depending on the thickness of the pieces and how dry they are.
  • After soaking, check the green onions for rehydration. They should become plump and tender.
  • Once the green onions are fully rehydrated, you can use a colander or gently squeeze the onions to remove the water.
