Plain canned beets (aka beet root in the UK) are delicious. What a treat to be able to pull a jar off the shelf on a weeknight, zap in microwave and serve with some sour cream and a sprinkle of dill weed on a blustery winter’s evening. Or toss in some olive oil or duck fat and have them roasting in the oven within seconds.
These directions follow the USDA recommendations.
When canned with a pressure canner following the USDA procedure, plain beets are a high quality, safe product. Otherwise, freeze plain beets. Or pickle them. Never water bath plain beets: the documentation trail of illness from doing that is as old as the hills. (See: Botulism in America.) PLEASE DO NOT ASK US IF PLAIN BEETS MUST BE CANNED WITH A PRESSURE CANNER, AS THERE IS NOT AND NEVER WILL BE ANY OTHER ANSWER THAN ‘YES, THEY MUST BE’.
To be clear for people outside North America, this procedure just applies to the root (tuber) part — the beetroot. The beet tops (aka greens) can indeed also be canned, but they must be canned separately and there is a separate procedure for that.

Quantities of beets needed
Numbers are approximate guidelines.
On average, as a very rough guideline, expect to need about 1 ¼ kg (3 lbs) of beets per 1 litre (US quart) jar of canned beets.
- 9 ½ kg kg (21 lb) of beets = 7 litres (US quarts) canned beets
- 6 kg (13.5 lbs ) of beets = 9 x ½ litres (US pints) canned beets
- 1 US bushel beets = 23 ½ kg (52 lbs) = 15 to 20 litres (US quarts) canned beets
10 medium ( 9 cm / 3 inches) raw beets, skin on = 2 kg (4 ½ pounds).
The recipe
Jar size choices: Either half-litre (1 US pint) OR 1 litre (1 US quart)
Processing method: Pressure canning only
Yield: varies
Headspace: 3 cm (1 inch)
Processing pressure: 10 lbs (69 kPa) weighted gauge, 11 lbs (76 kpa) dial gauge (adjust pressure for your altitude when over 300 metres / 1000 feet)
Processing time: Half-litres (pints) 30 minutes; litres (quarts) 35 minutes
Canning plain beets
Ingredients
- home-canned beets
- water
- pickling salt (optional. OR non-bitter, non-clouding salt sub)
Instructions
- Trim beet tops off, leaving 2 to 3 cm (an inch).
- Leave any roots on.
- Scrub beets well.
- Put beets in a large pot.
- Cover with boiling water. Bring back to the boil, and boil for 15 to 25 minutes -- until it looks like you can persuade the skins to come off easily.
- Remove beets from pot, and let them cool just enough to handle safely. Don't cool them beyond that; the beets should be at least warm going into the jars. The processing time is based on that assumption.
- Trim off roots and remaining stem bit, and peel.
- Leave very small beets whole; cut large ones into slices, or into 1 cm (½ inch) cubes. Cut very wide slides in half.
- Pack into half-litre (US pint) jars or 1 litre (US quart) jars.
- Leave 3 cm (1 inch) headspace.
- Optional: to each smaller jar, add ½ teaspoon of salt OR non-bitter, non-clouding salt sub. (Use 1 teaspoon for the larger jars.)
- Top up with clean boiling water (such as from a kettle, for instance), maintaining headspace.
- Debubble, adjust headspace.
- Wipe jar rims.
- Put lids on.
- Processing pressure: 10 lbs (69 kPa) weighted gauge, 11 lbs (76 kpa) dial gauge (adjust pressure for your altitude when over 300 metres / 1000 feet)
- Processing time: half-litre (US pint) jars for 30 minutes OR 1 litre (US quart) jars for 35 minutes.

Recipe notes
The purpose of leaving the roots and a bit of the stem on during the pre-cooking is to reduce some colour loss (in theory — there will still be a heck of a lot lost, so don’t get your hopes up.)
How long exactly you need to boil the beets will depend on the size of them. If you are doing a lot, it’s a good idea to separate batches by size for more even cooking.
Beets must be canned peeled. You are reducing the bacterial load going into the jars in doing so, and the procedure is counting on that to have happened.
The procedure tested expects the beets to be at least somewhat warm if not hotter going into the jars — so however tempting it is to chill them in ice water to make them more comfortable to peel, don’t. If for whatever reason they are no longer reasonably warm, zap beet pieces in microwave to re-heat before putting into the jars.
The salt is just there for seasoning. It is not a safety control factor.
Pre-cooking the beets
The overall point is that the beets must to be pre-cooked a bit, until the skins come off easily. And to reinforce that last notion, yes, they must be peeled. And, they must go into the jars hot, not cold, even if that means you have to re-heat them somehow.
That being said, we looked at two energy saving ways to pre-cook the beets.
1. If you have a steam canner, of the multi-canner type, you could try steaming them.
2. Pre-cooking the beets in a pressure cooker might not always save a lot of time when it comes to preparing beets for this recipe, but it will save resources such as cooking fuel and water, with the bonus of avoiding a steamy kitchen. Note that when you are boiling beets in an open pot, it is easy to fish out the smaller ones as they are ready and to leave the larger ones in longer. You can’t do that when pressure cooking them, so it can be useful to sort big bags of various-sized beets into sizes, and process in a batch or two based on size, to avoid overcooking the smaller ones.
To be clear, the following is NOT processing times for jars, they are pre-cooking suggestions for the beets as you prepare the recipe. And these are just suggestions. Times will vary based on how many beets you load at once into your pressure cooker. And bear this contradiction in mind: the more beets you have in at once, the greater the “come up to speed” and “cooling down” times which means you are getting a longer cooking time overall so the LESS actual cooking time at pressure is needed.
Medium beets (up to around 10 cm / 4 inches, larger ones sorted out for a separate load). 9 kg / 20 lbs. of beets at once in a 23 quart Presto at 15 pounds, try 3 minutes with 1 ½ litres / quarts of water. Afterward, natural release. This should produce beets that are easy to peel.

Canned beets losing their colour
Penn State Extension says,
The red pigments in beets (betalaines) are sensitive to high temperatures and can transform into a colorless compound during canning. Some varieties are more sensitive than others. The reaction is reversible and often the color of the canned product will return to a darker red after a few days of storage at room temperature. Some people recommend that you leave two inches (5 cm) of stem and tap root attached to the beets before boiling to remove the skins. Then trim the stem and root and slice, dice or leave whole for canning.” [1] Preparing Beets —Whole, Cubed, or Sliced for Canning” . Red Beets (losing colour in canning. Penn State Extension. Accessed January 2015.
Two good varieties for canning that hold their colour are: (a) ‘Detroit Dark Red’ Sturdy, which is round, and (b) Formanova, which are long beets. But, you would pretty much have to grow them yourself to ensure that you are getting them.
But as noted above by Penn State, with some other varieties, the faded colour may return on its own to being a deeper red after a short time in the jars.
The pale beets on the left were photographed right after canning in Sept 2015. The deeper coloured beets on the right were initially as pale when canned in November 2014, but regained their colour after a while on the shelf.
Judging criteria for plain canned beets
The National Center for Home Food Preservation’s judging criteria for beets says,
Must be canned peeled. Beets less than 2 inches (5 cm) in diameter may be canned whole; larger beets should be sliced or cubed. Uniform size and shape. Color should be dark, deep, and even. Brownish-red or faded color or white rings are undesirable. Liquid should be sparkling clear, red color with no cloudiness or sediment. Free from stems and roots or any traces of skin. Free from fibrous appearance (beets over 3 inches / 7 cm in diameter are often fibrous). [2] National Center for Home Food Preservation. Judging Home Preserved Foods. August 2003. Page 28.
Pressure-canning only for plain beets
The Putting Food By authors remind home canners that it’s pressure canning only for plain beets.
Only Pressure Canning for beets: they rank with home-canned string beans as carriers of C. botulinum toxin. Because they’re firm-fleshed, use Hot pack only.” [3] Hertzberg, Ruth; Greene, Janet; Vaughan, Beatrice (2010-05-25). Putting Food By: Fifth Edition (p. 136). Penguin Publishing Group. Kindle Edition.
From 1990 to 2012, there have been at least 10 people afflicted with botulism from beets that were water-bathed instead of being pressure-canned. (You can review the causes for those years in the US.)
But don’t panic: sucking on a raw piece of chicken would be dangerous, too. But if you cook chicken properly, you don’t give it a second thought. In the same vein, just pressure-can your beets according to directions and put them on your shelves, worry-free.
History
To be clear: this is the historical section, for educational purposes only. Don’t follow any of these directions; only use current USDA directions.
As early as 1926, advice to pressure can beets was being given out by the USDA. The USDA also explained why:
Because of spoilage difficulties and the risk of poisoning from occasional contamination with botulinus bacteria when nonacid vegetables are canned by the waterbath method, the department recommends the canning of such vegetables with the steam-pressure canner…… Baby beets.—Only young, tender beets should be canned, and the turnip shaped varieties make a more attractive product. Wash thoroughly and scald in boiling water or steam for about 15 minutes until the skins slip easily. Leave on at least 1 inch of the stems and all of the roots during this cooking to prevent bleeding. Slip off the skins, fill into the containers, add 1 teaspoon of salt to each quart, and fill with hot water. Process immediately at 10 pounds pressure, or 240° F., quart glass jars for 40 minutes, pint glass jars for 35 minutes, and No. 2 and No. 3 tin cans for 30 minutes.” [4] Stanley, Louise. Canning Fruits and Vegetables at Home. Washington, DC: USDA. Farmers’ Bulletin No. 1471. Page 19.
(As an aside, note that the processing times needed were presumed to be 5 minutes longer back then.)
Despite that previous safe advice, some home canning books issued by University Extensions during the Second World War era reverted to giving out dangerous advice about home canning beets.
Beets, Acid Method: Boil beets for 20 minutes, remove skins and pack beets in jars. Add 1 tablespoon of vinegar to each pint jar and fill with boiling water. Do not add salt, for it tends to draw out the color. Process for 1 ½ hours in boiling water. Beets canned under steam pressure are likely to lose much of their colour, so where acid flavor is not objectionable, this method helps preserve the color.” [5] Cameron, Janet L. and Mary L. Thompson. Home Bulletin No. 128. Blacksburg, Virginia: Virginia Agricultural Extension Service. Revised June 1944. Page 10. Access March 2015.
Note the false, unsafe assumption that a bit of vinegar would make plain beets safe for boiling water processing. Perhaps they were trying to be helpful, as pressure canners were rationed during the war owing to metal being needed for the war effort. Still, the dangerous advice lingers on.
Do not follow that slightly acidified advice or assume that because it’s old advice, it’s magically wise. Remember, even older advice pre-dates it, saying that such water-bathing of beets is unsafe.

I don’t have a pressure canner. I cook and skin beets, slice into quart cans. Add salt and boiling water. Put in canner and boil for an hour. Sometime later a week or more, notice the beets are turning a terrible color and would not want to eat them. What am I doing wrong?
Eleanor Pittroff
I wouldn’t want to shred beets. It just seems I’m doing something wrong.
Healthy Canning
Please see the third para at the top of the page which says canning with a pressure canner is the only safe and reliable way. If you don’t have a pressure canner, then freeze. Why waste all that food, time, work and cooking fuel?
Jeanette
Can you shred your beets and parboil them and then fill your jars with the Shredded beets and the same liquid that you cooked your shredded beets in. This way it will retain its color.
Healthy Canning
Canning directions are meant to be followed as given, even though they didn’t always have the ink space to explain the why behind their directions. Don’t shred the beets; that’s going to affect the density and heat flow in the jar during sterilization. How the heat flows in a jar during canning is critical.

How do you cold pack beets, not pickled? no pressure cooker
Healthy Canning
You don’t.
Donna
I don’t have a pressure canner I have been canning red beets all my life I am 73yrs old.I use a hot water bath method I never had anyone get sick but now I am second guessing my method is this method okay and how long should I be boiling the jars of beets
Healthy Canning
Plain beets must be canned using a pressure canner; I see the stats and botulism does occur with jars of plain beets that are water bathed. Directions are above. Without a pressure canner, you could freeze the beets, or, pickle them and water bath those jars of pickled beets. Beet slices can also be dehydrated.
Karen Woltering
My recipe for plain beets is to add 1tsp salt and 1 Tbs of vinegar, then pressure cook in a pressure canner for 15-20 mins.. you don’t taste the vinegar, but my beets never lose color. This recipe is for quart jars. Is this recipe up to USDA standards, because I just kind of made up my recipe. If I wanted to add a tsp of sugar, would it be up to USDA standards?
Healthy Canning
Adding a tablespoon of vinegar is fine, and yes you could add sugar, both are just seasonings here, but, the processing time is what they would term “grossly inadequate” and those jars should be discarded for safety. The tested processing times are pints 30 minutes; quarts 35 minutes.
Gerry Jacobsen
While pressure cooking the beets in jars a lot of the liquid seems to boil out is there some way to prevent that?
Healthy Canning
A lot of it comes down to how to manage your pressure *canner* while it is running. See pressure canning step-by-step: https://www.healthycanning.com/pressure-canning-step-by-step/
Laurie
So your plain canned beets do not lose their color add 1 Tsp vinegar, 1/2 tsp salt, 1/4 tsp. Fruit fresh to one pint of beets. They will be as red after you pressure can them as they were fresh,
Michael P Schofield
I am growing another large quantity for my wife. It seems as though we lost a lot of beet flavor when we boiled them to take the skins off.
I am searching for a means of baking them in large quantity and then canning with a pressure cooker.
Any experience with this? I’d like to use large covered roasting pans & then peel. I just don’t want to waste them an an experiment.
Tips to keep things moving along when we are processing 3-4 bushels and using the water bath method?
I usually have large pots going for this outdoors and cook a couple batches in the same liquid.
Thank you!
Sharon Pulscher
How do you keep beets to retain their red color when canning them?
Healthy Canning
Hi Sharon, see dedicated discussion on above page. At one point, we did try adding red food colouring to the canning, but it had little effect, and overtime, we just stopped worrying about the lighter hues after canning.
rene
Why can we not just peel them with a potato peeler and then heat them? this way we could
pack them in the red water they were heated in
Healthy Canning
The parboiling step helps to start reducing the bacterial load. This is an example of the reason canning recipes are meant to be followed as they are written. I sometimes wish they’d add a few sentences explaining the rationale behind the steps.
Jeri moore
Info very helpful
Barbara Amason
No salt at all for can Ning beets w pressure cooker??
Just hot water n peeled beets???
Healthy Canning
Yes, salt is optional. In the quantities used in home canning, salt is not there for safety. The safety comes from the heat treatment and the tested processing times and methods. Be sure to use a certified pressure canner, rather than just a pressure cooker.
