When it comes to canning vegetables, it is important to find veggies that keep the best and have a high nutritional content and offer a good value for your dollar and time spent.

Here are some things to consider and a few of the best veggies for long term canning.

What is most readily available locally?

I live near a ton of tomato and sweet pepper fields. There are also a lot of hot peppers at the farmer’s market. Cabbage is another cheap and readily available vegetable.

Tomatoes can be had for $10 for a 25 lb box for standard canning tomatoes whereas heirlooms like Cherokee Purple can go for $25 for a 25 lb box. The price goes down at some point in the season until you can get regular tomatoes for as little as $7 a box or even less if you want to go directly to the packing house.

Find out what you can get for the best price locally and think about what you can do with it. The bell peppers and hot peppers I mentioned are expensive out of season, costing $1 per bell pepper or more and pickled banana peppers are at least 10x the cost they are if I can my own.

The Art Of Pickling; Cucumbers, Cabbage, and More

There is a lot to be said for utilizing the art of pickling. To avoid soggy pickles of any sort you need to use pickling lime, which is very inexpensive and takes care of the problem easily. Fermented pickles are another option of course and have more health benefits.

You can take cucumbers or cabbage and make enhance the nutritional content of the foods beyond what they have to offer raw or even cooked. Fermentation is a beautiful think when it comes to taking bland foods and enhancing flavor and overall nutritional value.

Peppers are also very good pickled and keep well. Backdoor Survival has some informative articles that cover the pickling and fermentation processes much more in depth. 

The Wonderful World Of Tomatoes

You can use tomatoes as a base for a lot of good canned foods. While I am lucky to live in a place where tomatoes are plentiful, in some areas they are not so cheap.

You can do well growing your own if you have the space to do so. Tomatos have a lot of vitamins and nutrients and amazing versatility. Salsas, whole or diced canned tomatoes, marinara sauce, and more have a delicious place in your prepper pantry.

Beans Of All Types

Green beans are very expensive when fresh in the winter. Buying frozen means $3 a lb and you have to maintain freezer space. You can grow a lot of pole beans in a small space or buy them in season at a local farmers market for a reasonable price. Of course, if you want Greasy Cut Shorts, those are going to be twice as much per bushel in some cases.

Green beans are one of the few things where I have to advise using a quart jar for. You can also make Dilly beans which I used to devour by the jar when I was a kid. My grandma couldn’t keep them around for me eating them all the time.

Dried beans can be cooked and canned which I can see the argument for doing this because dried beans take forever to cook in a survival situation. This has been something I have struggled with as a prepper.

Beans are cheap to put back but they sure take forever to cook even if you soak them! 


Carrots will can well and maintain a good texture. If you find a good deal on them then consider canning them up. Carrots can be a challenge to grow without the right soil. You need it a bit sandy with good drainage.

Personally, if I was going to can a lot of these I would just go down to the grocery store and get the giant 20 lbs or more bag of Earthbound Organic carrots. They are sold in quantity for juicing but are of high enough quality to be excellent to can.

If you are picking and choosing what to grow in a small space, the low price of carrots at the store might mean you should save your space for other higher value veggies.

Pesto & Tomato Based Oil Spreads

While I know basil is technically an herb and not a veggie, I want to include it here because it keeps a long time and Basil is very prolific even if you just have a small patch.

Using olive or sunflower seed oil for your pesto and canning it results in a product that will last for many years. You can easily use pesto that has been canned for 4 or 5 years if it has been sealed well. I just know that a lot of people grow some herbs alongside the veggies they want to put back!

You can also make oil based spreads with tomatoes that can keep longer than regular tomatoes. Anytime you add salt or oil and seal well, you are usually extending the shelf life of your food some.

Time Versus Calories

I love canned veggies and pickles and the like definitely add variety to your prepper pantry. On the other hand if you are pressed for space for supplies, you are better off dehydrating veggies and canning meat. This allows for the maximum nutrition value in the smallest space.

Vacuum seal bags and moisture absorbers combined with a dehydrator means you can fit a lot more veggies in the same space. Dried veggies also maintain their nutritional and caloric value more easily.

I am not trying to discourage canning. I love to can and it is a good method but I also have a lot of space to stash things. If I was prepping in an apartment it would not be realistic for a major food supply.

In these articles, I want to make sure to try to consider the situation of others instead of just saying what is useful for those with more storage capacity. Prepping is important to do regardless of what your living situation is but it does need to be approached differently based on family size and space.

Salt Matters

Salt is a preservative thus saltier foods just keep better. While a lot of people have to watch how much salt they consume, when it comes to canning you should consider adding a little more than you would normally. In an emergency, you may need it.

Working hard means you lose salt more easily through sweating and without adequate salt you can start to feel pretty awful. It has happened to us more than once working on our place during good times but in the summer.

During the Vietnam War they would give soldiers salt tablets for this very reason. I would not be surprised if this was still a thing that happens when troops are in hot places and going hard.

Best Dollar Value For Your Time

Canned soups are expensive so when it comes to veggies I have found going the mixed route is the best bang for your dollar.

I think combining a lot of the vegetables discussed above for a soup blend is a good way to go as well. A tomato base with your choice of any combination of the veggies in this article. You may even do several different types of these mixes.

Going the variety route is helpful because then you are not stuck eating a while pint or quart of one vegetable. This may not matter so much for those that are planning on cooking for a whole family but for one or two people, even a pint of just one thing may be too much.

You can also add meat to soup mixes but if you do this you will need to use a pressure canner and process as you would meat. My husband and I have done this a lot to make healthy convenience food for ourselves and my father who is on a salt and sugar restricted diet due to diabetes.

The Essentials Of Canning Supplies

Below is a list of supplies you will find necessary. There are also kits that you buy that contain a lot of what you need to get started.

  • Hot Water Bath Canner Or Steam Canner
  • Large stainless steel pots – You can use a large pot as a water bath canner too.
  • Strainer or colander
  • Jars & Extra Lids
  • Lid Lifter
  • Funnel, Ladles, and Spoons
  • Citric Acid
  • Spices
  • Non Iodized Salt.

Classic Enamel Water Bath Canner

The above canner is ideal for those just starting out and that are on a budget. I recommend getting two of them if you are planning on doing a lot. These also make great stock pots for cooking down sauces and preparing veggies.

Granite Wear Canning Kit

This kit is more complete and will get you started. The tools are nice to have.

I started out canning without them years ago and quickly realized they are worth the investment for handling hot lids and jars without injury. A good funnel means less mess and faster jar filling.

Regarding Lids and Rings

There are reusable canning jar lids that you can get. Tattler is the most common brand out there. They are more expensive of course and you wouldn’t want to use them for canned goods you are going to give away.

Rings need to be replaced after they get too rusty or mangled. This happens more readily if you are keeping your veggies in a damp space.

Why I Don’t Suggest Corn Or Potatoes For Canning

I want to address why I have not included two of the basic veggies out there.

  1. Corn
  2. Potato

The simple fact is that buying corn on the cobb or growing it and canning it is an insane amount of work. The average person just doesn’t have the time for this veggie. While there are tools to get the corn off the cobb, it is incredibly time consuming for the amount you get.

If you have the patience then go for it!

Corn is definitely delicious canned and it keeps well but for the cost and the amount of work it is I will be buying mine already canned. Of course we don’t eat a lot of corn so you may feel different about all this.

I remember growing a big corn patch and being amazed how few jars I got for the amount of work done!

Potatoes are so inexpensive and easy to keep in a cool place that I don’t think they are worth it to can. You would be better off slicing potatoes thin, using citric acid to keep them from turning brown, and dehydrating them.

For further preservation, you can use a moisture absorber with a vacuum seal bag and your sealer for very long term use.

Canned Vegetable Shelf Life & Food Safety

If you listen to food safety experts they will say that ideally you should rotate out canned goods within a year or two. This is mostly just because the flavor can start to deteriorate over time. This can happen even faster if your canned goods are not kept at a steady cool temperature.

The 50 and 60 degree Fahrenheit ranges are a nice rule of thumb. Too much light can also have an effect on color over time, especially if you did not use citric acid or similar to preserve it in the first place.

Even under good conditions though, it is wise to try to consume canned vegetables within 3 years.

Of course if you notice any off flavors, smells, or a jar has become unsealed, it is best to exercise caution. Botulism and other food borne illnesses can be very unpleasant and can sometimes be fatal, especially if a child, elderly person, or anyone with a compromised immune system gets infected.

What if a jar doesn’t seal?

If you catch the fact that a jar hasn’t sealed within 24 hours of attempting to can it, you can try to process it again. In this case, you should check the mouth of the jar for debris or ridges in the glass. You should also consider using a fresh jar lid.

Jar Life

Over time, jars can get small cracks or chips that are hard to see. If you are reusing your jars year after year, you should give a quick inspection of them when cleaning them for use.

Of course, you should never use old mayonnaise jars for veggie canning. You can get away with that for some jelly and jams but they are so thin compared to a Mason jar and are definitely not made to withstand the pressure of a pressure canner.

If cracks or chips don’t happen then a jar can be used for many years. My personal opinion though is that if a jar has been used for pressure canning a lot, they are more prone to a short life from the stresses of the pressure put on them and the temperature changes.

  1. A pressure-cooker is a great help in preparing dried beans. After soaking 1-1/2 C of dried kidney beans for a day, I spent about 10 minutes on “high” bringing the pot to a boil, then 30 minutes on simmer/low (just gently hissing from the pressure-relief valve), then about 10 minutes cooling (on the stove). The beans were perfectly tender.

    Before dehydrating potatoes, try blanching them in boiling water for a couple of minutes. That prevents them from turning gray, without the acid bath.

    In my humble opinion, home-canned applesauce is much tastier than anything sold in stores. Maybe it’s the selection of apples, or the minimum added water, but it’s a staple around here. Ingredients: apples (and a little water to make steam for efficient heat transfer). Home-fermented sauerkraut, because it’s never cooked, is also much crisper and tastier than commercial. I use red cabbage, which is beautifully rosy-red due to the lactic acid. Ingredients: cabbage, salt, water.
