Making the Harvest Last: You Can Can Soup!
There seem to be many blog posts all about cooking 5 , 10 , or um, even 20  meals in one day and freezing them all and eating easy for a week (or a month, year, lifetime, etc.). While this appeals to me it’s generally impossible for my family to do because we lack the freezer space. Our freezer is mostly full of frozen fruit from the summer.
Everyone has their priorities, but I would appreciate having a bunch of meals that I could make in a day and then eat simply by pulling them out of the freezer in the morning and stuffing in a crock pot. Alas, I don’t think we’ll have the freezer space any time soon.  Furthermore most of those meals I see  feature large amounts of meat, and we prefer to not eat large amounts of meat all the time.  However, we do have pantry space and a pressure canner….
This summer I was on the National Center for Home Food Preservation  website ( yes, very long name, shall we just refer to it as the Food Pres site?  No, I agree, we will keep referring to it by it’s easy name, the National Center for Home Food Preservation) and I came across directions for canning soup. Let’s all read what it said together, because if they  said  it’s safe  then it works for me!
They go on:
And then the table:
Thanks to that info I have felt sufficiently confident this harvest season (which, from what I can tell just ended) that I can cook up delicious soups like Cream of Broccoli, sans the cream, can the heck out them, and stick ‘em on the shelf until we need a quick and easy meal. Now, you’re thinking to yourself, “well I  have a huge empty freezer so I’m  going to stop reading and just freeze me some soup and I will take the time to defrost it and cook it for an easy dinner†and that’s fine for you but like I said before, I  don’t have the room in my  freezer. But really even that’s not why this appeals to me.  For me it’s the convenience of food in a jar.
How I Arrived Here:
Two months ago I came home from the market garden I volunteered at over the summer with the biggest zucchini ever. It was a nasty ogre of a zuke. It barely fit in my bike’s saddle bag and I had an even harder time figuring out what on earth to do with it, besides take a picture of it on my rustic wood table….
Next time I’ll put something next to it to show how big it was.
Anyways, point of the story is I ended up cooking a pretty big batch of Cream of Zucchini and Potato soup and decided to stick it in jars and pressure can it. I then stuck the jars in the basement pantry until a few weeks later when we were in a hurry to eat and we decided to have one. It was great! Compared to eating a frozen meal which either requires forethought or liberal use of the microwave, this soup was simply cracked open (easier than Campbell’s) and heated up on the stove. A bit of cream was added and we had a simple, tasty dinner of soup and leftover bread.
Then I started feeling sad that we had one less jar of soup in the basement.  (These are the kinds of things that make me sad, I know, lame).  So I started scheming (my word for planning, and others call it “preppingâ€). Next up came Cream of Broccoli with a few heads of broccoli that I had forgotten in the fridge. They were nearing the end of their freshness but made a great soup and got us three more large jars to add to the pantry supply.  We enjoyed one of them a few weeks later when in a rush again for a meal. And once again I was very pleased with the results but also sad at the declining supply of easy meals on the pantry shelf.
This past Saturday I came home from the market with what will likely be the last broccoli of the season. I bought quite a bit.  I had ridden my bike to the market and had a lot of trouble fitting everything in my bike saddle bags and backpack.  It also snowed while I was there and I rode home on snowy roads.  It was kind of absurd, but also fun!
On Sunday afternoon I washed the broccoli, cooked up a large pot of Cream of Broccoli without cream (look back at the instructions from the National Center for Home Food Preservation website and see that cream does not go in the jars), and then canned it to smithereens! Well, not quite, but I did can it. I mean I can did it.  I mean, you can do it.  No, the first was right.  Well, the last was true too, I can and so can you can!  Even Toucan, Pelican, Pecan, and Republican.  Okay, enough gibberish and rambling, see below!
(Canned) Cream of Broccoli
Recipe from (IMO)Â the most useful cookbook ever .
Enough to can 6-8 quarts/liters (I got 7, which is just between 6 and 8).
- 1-2 Tbs. olive oil (be sure to keep oil to a minimum  when canning)
- 3-5 onions, chopped
- 4-5 celery stalks, chopped
- 5-7 lbs broccoli, washed and coarsely chopped
- 1 gallon (16 cups) broth (chicken or vegetable)
- Salt and pepper to taste
- No cream now, but when you cook up your canned soup later, add ¼ – ½ cup cream or milk
- Dash of nutmeg when you cook up later.
Heat oil and fry up onions and celery until beginning to soften. Add broccoli, and stir briefly with the onions and celery. Add broth and bring to a simmer. Because you’re about to cook this under extreme pressure you do not need to fully cook the broccoli, just get it soft enough to puree with an immersion blender or working in batches in the food processor (I’m thankful for a lovely neighbor who lent me her immersion blender!  I shall have to give her one of my precious jars of soup…).  Add salt and pepper to taste and get ready to can!  Keep the soup at simmer.
Canning Instructions
- 8 quart/liter jars
- 8 lids
- 8 rings
- Pressure canner (we have this one )
Wash and sterilize jars, lids, and rings. Prepare pressure canner by filling with water to recommended fill line and boiling. Heat jars in 220◦ oven or in boiling water.  Fill jars, leaving 1-inch headspace. Clean the tops of the jars and attach lids and rings. Put lid on canner, blow steam out for 10 minutes to get all air out of the canner. Attach pressure regulator and process quarts/liters under 11 PSI for 75 minutes. Make sure to allow the pressure to completely drop before opening the canner to remove the cans. When they are cool (hey man, they were always cool, wait, what?) the next day remove the rings and store until you need an easy meal!
Instructions in Photo Form:
FYI: The intense heat of the pressure canning process may cause the soup to lose its nice green color. The flavor won’t be effected but if you’re wanting soup that retains its color try making a soup with vegetables of a different color.

I love the idea of canning soup, but I don’t have a pressure cooker. Do you have any suggestions on how long I would boil the jars without one?
Thanks

Hi Dianne,
Sadly you can’t heat it hot enough without a pressure canner to ensure the safety, at least according to the experts. Pressure canners are awesome, I can’t recommend them enough. Here are two good options well worth the investment: Presto 23-Quart and Presto 16-Quart

You are absolutely right, Jon. Buying a canning pressure cooker is a one-time purchase. I have been canning in mine for 32 years and it is still going strong. Especially if you are a gardener or hunter, the investment is one of the best ones you will ever make. Boiling water bath canning is only for acidic foods like fruit, pickles and tomatoes. I can beef, chicken, venison, beans, spaghetti sauce with meat, chili, you name it! I am currently trying to can the meat in my freezer to make room for a new side of beef. I can’t tell you what the satisfaction feels like of knowing that even if the electricity goes out, our food supply is safe and certain. While I will agree it is a lot of work on the front end, it’s like fast food when you are ready to eat it! Opening a jar and heating it up is a lot faster than getting in the car and going to the drive thru.

So it’s 2018 and I just found your idea of cream of broccoli . Just in time for this years canning season. Regarding your comment about the color change , would adding lemon juice or citric acid help keep the color ? I add it to me green beans to keep them pretty and doesn’t change the flavor .

Keep an eye on garage sales or use craigslist. I got both of my pressure canners for 5 bucks. Even if you have to replace a seal or something, it still is way cheaper than buying new if you don’t have the finances.

Thank you, this is one I was wondering about, I make basic green soup, and potato soup, and butternut soup. I do know not to can with the milk product added to soup. After opening is best

Why do you remove the rings from the jars?
Jon Spee
September 30, 2014 @ 7:11 pm
Great question, Mike. It’s for a couple reasons. The first was that we found that sometimes the rings would get stuck and we’d have a very difficult time getting them off after several months, especially if a little bit of whatever we were canning had ended up around the opening (which it shouldn’t, but sometimes does). The second reason is to verify that indeed our lids are sealed. If anything weird happens inside the jar it will likely pop the lid off because microbes tend to create gasses. This will be a helpful indication that all is not well in that jar and we’ll know not to eat the contents.

I tried your recipe today and the soup ended up a yellow-brown color, I presume overcooked during the canning process. Any tips to avoid this is the future?

Hi Amanda,
I’m afraid it’s just part of the process. All of our canned soups have had rather dull colors. The photos on this blog post are the before shots (I’m going to add a caption to the photo above stating as much). From what I’ve just read the color change in this case is the result of the high heat of the canning. The soup should still taste good, and maybe you can add some fresh herbs to bring back some of the color when you eat the soup. Otherwise if you want to avoid this you may need to go with frozen soup.

Hello, Just a quick question. I make a homemade Butternut Squash soup which has celery, carrots, onion, garlic, cream cheese and of course a large amount of butternut squash. I was told you can’t pressure can any cream soups… so I’m excited to hear that I might be able to can cream based soups. Do you know if the cream cheese will be an issue?
And a comment… I was in Germany in September 2015 and my mom’s best friend made her sultze… I believe in North American that would be headcheese (although I don’t understand the name since there’s no head or cheese in the recipe) but I’m wandering off topic. Anyway it’s quite the process and cooking the headcheese takes upwards of 8 hours. And although it has pork in it they never pressure can it. When I asked why I was told why would you? You put it in the jar boiling hot and the jars are boiling hot. Nothing can survive that. Then they store it in the dark. She’s in her 70’s and her gramma gave her the recipe. So passed down for generations. My Omi did the same. I sometimes wonder how everyone survived. lol According to today’s standards everyone I know should be dead. 😉
Love your blog. Makes me happy to find some common sense canning. Cheers, Diane

Hi Diane, I think you’d be okay canning your butternut soup but I would omit the cream cheese. You can just add it when you open the jar and heat the soup up. Regarding the headcheese I’m not sure about the statement “nothing can survive that” since botulism can indeed survive boiling temperatures. It’s the acidity (from vinegar or high-acid fruits/veggies) that ends up killing it in hot water bath canning. For low-acid foods (like soup in this case)the high heat of pressure cooking is what kills the botulism.
Obviously people don’t get too sick from canned foods very often but I’m not really ready to break the rules. I think it is good though to know the reasons for the rules because then you can apply them with common sense. Anyway, thank you for stopping by and sharing 🙂

I’m glad I’m not the only one who is sad when they take something off the shelf! I’m down to one salsa (and last year’s came out soooo awesome) that I almost don’t want to use it.
I do have a quick question. I’d like to make this in pint jars (I make soups for my dad so he can watch his sodiium and carb intake). Would the psi and cooking time stay the same? Our broccoli is going crazy this year and I know my father would love the soup. Thank in advance!

Hi Michele,
According to the table above you’d reduce the time to 60 minutes but keep the pressure the same.
Cheers!

would you post the recipie for the cream of potato and zuchinni soup please. I have tons of broccoli left and I have alreadyfrozen 45 qt.bags in my freezer.
kitchen'r jon
October 23, 2016 @ 2:18 pm
Hi Beth,
I’m afraid I can’t remember what cookbook or website the recipe came from but it was very basic. The idea with any soup recipe for canning is to leave out the ingredients that shouldn’t be canned, in the case of the creamy zucchini and potato soup you’d want to leave out the cream and add that fresh.

Jon,
I like to have some larger than puree, smaller than whole size pieces of broccoli in my Cream of Brocolli soup, would you recommend leaving them that size prior to canning?
kitchen'r jon
January 12, 2017 @ 6:09 pm
Hi Jeannie, I think I would can them as whatever way you want the finished soup to look. So if you like some chunks leave them that size from the beginning. Cheers!

could you use food color to keep the green color in the soup. I do it with end of the garden chow chow

I don’t see why not (other than the fact that some people don’t like artificial coloring in their food).
