Canning butternut squash soup base is a delicious way to have a home-cooked meal in a jar ready right on your pantry shelf. Since butternut squash cannot be canned as a puree, this recipe cans butternut squash soup as chunks, and you simply puree the soup before heating and serving. Everything’s in the jar, cooked and ready to puree, heat and eat.
Does anything say “fall” quite like butternut squash soup? We think not!
Nothing compares to the taste and freshness of homemade butternut squash soup base – so why not make it a year-round staple in your pantry?
Pressure canning is the safest and most effective way to preserve low-acid vegetables like squash, providing you with a safe way to extend their shelf life for up to 18 months (and sometimes even longer).
Butternut squash is perhaps the most popular squash for canning because it is the easiest to peel and cube. All you have to do is peel your squashes with a vegetable peeler, cut in half, then remove the seeds. Easy enough, and you can even save the seeds for roasting and snacking later on.
The beauty of this recipe is that it creates a soup base that can be served on its own or used as a starting point for all kinds of recipes, including pastas, more complex soups and stews, and sauces. It’s versatile and highly nutritious.
Here, we’ll show you how to pressure can butternut squash soup base at home, giving you an incredibly delicious and nutritious meal that will last all winter long!
Ingredients for Canning Butternut Squash Soup Base
This recipe is adapted from the Homestead Canning Cookbook by Georgia Varozza.
It’s based on the instructions for canning pumpkin and other winter squash, as well as the National Center for Home Food Preservation’s instructions for canning soup at home.
It follows all the principles of home canning, and cans the squash as a soup base that’s pureed to serve (rather than pureed in the jars before canning).
This recipe for canning butternut squash soup base is pretty basic, and it uses butternut, onions, celery, carrots, and potatoes, which give the finished soup a bit of body and creaminess.
You can add in whatever spices you like, as you’re always allowed to add reasonable amounts of dry spices to any canning recipe. That’s one of the lovely things about pressure-canning soup recipes in general. You can make them your own simply by changing up the spices.
You’re also allowed to add sugar (as well as honey, maple, or my favorite in butternut squash soup, homemade apple cider syrup (you can also buy Vermont made cider syrup online). Just a dash of it goes a long way, and really makes the flavors of this simple butternut squash soup pop.
Alternatively, you can replace some of the broth, maybe about 1/3 of the total, with fresh apple cider for amazing flavor.
Canning butternut squash soup base is easy and requires just a few simple ingredients. To make a canner batch of 10 pints or 5 quarts of soup, you’ll need the following:
- 5 lbs butternut squash, peeled and cubed into ½ inch pieces
- 2 ½ lbs red potatoes, peeled and cubed into ½ inch pieces
- 5 stalks of celery, chopped
- 5 carrots, chopped
- 3 onions, chopped
- 2 tablespoons of salt
- About 3 quarts water or broth to cover the vegetables in the jars
You can use any kind of butternut squash, potatoes, carrots, celery, and onions you’d like for this recipe.
There are a few adjustments you can make to this recipe to suit your tastes. All of these variations follow guidelines for safe canning released by the National Center for Home Food Preservation.
You may choose to leave the other vegetables out of this recipe, and that’s fine. Make sure you do not mash or puree the squash until after canning. Mashed or pureed vegetables do not heat evenly inside a canning jar and so your finished product could be unsafe to eat.
Another possible recipe variation is to add chicken stock (instead of veggie stock). You can add four cups of chicken stock for every five pounds of butternut squash you can, using this instead of water when you cover the jars.
You can also add spices and other herbs as you choose without having to worry about them affecting the safety of your finished product.
For a savory variation, try adding thyme and rosemary.
For a savory, earthy soup, add about ¼ teaspoon of nutmeg per quart.
For a Thai-style butternut squash soup, you might consider adding a tablespoon of red curry and two teaspoons of fresh chopped ginger.
Molasses, cinnamon, and a bit of allspice also work wonderfully.
Canning Butternut Squash Soup Base
All vegetables should be washed thoroughly to remove any lingering traces of dirt, and the carrots, squash, and potatoes should all be peeled. Wash these vegetables before you peel them so you don’t drive dirt and bacteria into the flesh as you peel.
Your next step is cutting the squash, potatoes, celery, carrots, and onions into cubes.
You must also remove all seeds from the squash.
Put the potatoes and squash into a large stockpot. Cover with water, then bring to a low boil and boil for two minutes.
Avoid boiling for longer than two minutes, or the squash and other vegetables will break down and become mushy later on.
Add the remainder of the ingredients and mix to combine.
Put the hot mixture into jars, leaving an inch of headspace.
Ladle boiling water over the vegetables, making sure the inch of headspace still remains.
Remove air bubbles and wipe the lids to remove any food particles.
Process quarts for 90 minutes and pints for 75 minutes at 10 lbs of pressure, adjusting as needed for elevation.
When the canning time has elapsed, allow the canner to depressurize naturally. Then, remove the jars and allow them to cool for 24 hours before storing them.
Altitude Adjustments for Canning Butternut Squash Soup Base
Canning time remains the same regardless of altitude. However, the processing pressure increases as altitude increases.
Use the following table to determine the correct processing pressure if you’re above 1,000 feet in elevation.
For dial gauge pressure canners:
- 0 to 2,000 feet in elevation – 11 lbs pressure
- 2,001 to 4,000 feet in elevation – 12 lbs pressure
- 4,001 to 6,000 feet in elevation – 13 lbs pressure
- 6,001 to 8,000 feet in elevation – 14 lbs pressure
For weighted gauge pressure canners:
- 0 to 1,000 feet in elevation – 10 lbs pressure
- Above 1,000 feet – 15 lbs pressure
Butternut Squash Soup Variations
We’ve already discussed a number of variations in spicing, but you can go a bit further. There are other butternut squash (and pumpkin) soup canning recipes out there, and combining inspiration from more than one isn’t a bad idea.
I’m particularly fond of this recipe for butternut squash and white bean soup. It’s hearty and filling, with just enough butternut to give it amazing flavor.
For a really unique twist, you can also try the Thai Coconut Squash soup recipe that Ball Canning developed.
Serving Butternut Squash Soup Base
To serve, drain the water from the cans.
The only downside to canning butternut squash is that it tends to be the wateriest of all the winter squashes, so you will need to strain the excess liquid before you do anything with it.
Then, puree in a blender for a smooth soup or mash with a potato masher for a coarse mix. Add a cup of cream or milk to the soup and heat, adding any other spices if desired (good choices are parsley, curry, ginger, and nutmeg).
Add a dollop of sour cream to each serving – and enjoy!
If you’d like to take your dinnertime game up a notch, you can add other ingredients to this soup or use it as a base for all kinds of different recipes.
Use it in a casserole, as a pasta sauce, or even as a base for more complex soups (some popular options include a butternut squash soup with apple, kale, and bacon, or even a butternut squash soup with goat cheese and sage).

Notes
This soup base can be made in any type of broth or stock, or plain water. To fill the jars and cook the soup, you should need about 3 quarts of broth or water. Have a kettle heating on the side to help fill the jars if you run short of liquid. The jars should be filled to within 1'' of the top rim with liquid to ensure proper processing. (Make sure you have no more than 1'' headspace, but also no less than 1'' headspace.)

Would it be safe to pressure can this recipe and include shredded chicken? There is a recipe I make just like this, but no potatoes, and with chicken, and serve over rice. Its delicious, and would be great if I could can with the added chicken.
