How to preserve vegetables for winter?

In this brief guide, we are going to answer the question “How to preserve vegetables for winter” and discuss the different techniques of preserving vegetables for winter.

How to preserve vegetables for winter?

Vegetables can be preserved for winter by using one of the following ways:

  • Storing whole vegetables under proper storage conditions: Using the correct storage conditions such as temperature, humidity, and light.
  • Freezing
  • Dehydrating
  • Pickling
  • Canning

Storing whole vegetables under proper storage conditions

The proper storage conditions will preserve vegetables for winter without needing any additional preservation methods. 


Different vegetables require different storage temperatures. Vegetables like carrots, beets, and leeks must be stored at colder temperatures while potatoes, pumpkins, and onions prefer warmer temperatures.


Most vegetables that require colder temperatures also need high humidity. A storage room can be made more humid by placing buckets of water to evaporate. 


Most vegetables store well at dark temperatures. Exposure to light can cause vegetables like potatoes and onions to sprout.

Curing the vegetables before storage

Some vegetables must be cured before storage. Curing hardens the skin on the vegetables and allows longer storage. Potatoes, sweet potatoes, onions, garlic, and squash are vegetables that need to be cured. The conditions for curing depends on the vegetables.

Trimming off leafy tops

Vegetables like carrots, beets, and radishes have leafy tops. These leafy tops will absorb the moisture from the roots, causing the roots to dry out. Leafy tops can also harbor insects. Always trim the leafy tops before storage.

Prevent washing the vegetables

Never wash the vegetables before storage. Washing will introduce moisture and this will cause the vegetables to spoil. If the vegetables have a lot of soil on them, brush them with a soft brush.

Discarding spoiled vegetables

A few spoiled vegetables can ruin the whole harvest. Remove spoiled and insect-damaged vegetables as soon as you spot them.

Preserving vegetables for winter by freezing

One of the simplest methods to store veggies for the winter is to freeze them. 

Except for potatoes, sweet potatoes, onions, and pumpkins which tend to get limp and soggy, almost all vegetables can be frozen.

Most vegetables must first be blanched, which includes boiling them for a specific time (typically 1-3 minutes). Blanching stops enzyme activity, preserving color, flavor, and nutrition. After blanching, the vegetables are immediately cooled in cold water. 

Pack the vegetables into plastic containers or freezer-safe ziplock bags before freezing.

How to preserve vegetables for winter by dehydrating?

Vegetables can be dried in a variety of methods and then rehydrated for use in soups and casseroles in the winter. The most convenient technique is to use an electric food dehydrator, but you can also dry vegetables in the oven or even in direct sunshine. 

When compared to traditional canning, dehydrated foods take up significantly less space and have a much longer shelf life. Dehydrated vegetables have a stronger flavor than fresh vegetables. Vegetable soup with dehydrated vegetables is a great dish for the winter.

Before dehydrating vegetables, they should be blanched. This helps to avoid discoloration.  It is not required to blanch vegetables like onions, peppers, garlic, or herbs.

The only downside of dehydration is that it takes time. Dehydration will take about 4-8 hours, depending on the thickness and moisture level of the vegetable. Watery vegetables like zucchinis will take longer to dehydrate.

Fully dehydrated vegetables should be dry brittle. 

Store dehydrated vegetables in labeled air-tight containers in a cool, dark, and dry place.

Vegetables commonly preserved by dehydration are tomatoes, pumpkins, and zucchini. 

How to preserve vegetables for winter by pickling?

Pickling is a food preservation process that involves immersing vegetables in a brine solution to extend their shelf life. Most vegetables can be made into pickles. Examples include cucumber, radish, beans, peppers, squash, and beets. 

Pickling is a great way to preserve vegetables for the winter. Pickled vegetables can be eaten as a side dish or by adding to sandwiches and burgers. 

Winter pickles can be made by a combination of multiple vegetables that are out of season in the winter. This way you can enjoy these vegetables throughout the year. There are many recipes for winter pickled vegetables and each of them uses a different mix of veggies. This recipe makes winter pickles from radishes, fennel, beets, and butternut squash.

How to preserve vegetables for winter by canning?

Canning is one of the more difficult techniques of preserving vegetables, but it is quite simple if you take your time and carefully follow the instructions. 

Some foods may contain harmful bacteria if they are not treated properly, so canning must be done correctly. Most fruits and vegetables can be canned in a boiling water bath, but low-acid vegetables like beans, peas, carrots, corn, and squash should be processed in a pressure canner.

Here are step-by-step instructions on water bath canning and pressure canning.
