Home canned sweet potatoes are a great thing to have on hand for soups, side dishes, and especially during the holidays!! And since they usually go on sale in the fall, this is a great time to stock up and can enough for the whole year!
Read on to get the full details on how to can sweet potatoes for your well-stocked pantry!
As with all vegetables, sweet potatoes have to be pressure canned. If you have never done that before, it can be a little overwhelming and even scary to thing about trying!
Rest assured, it is a simple process that you can quickly master. Read my step by step guide on pressure canning if you are new to the process - this post will not be as in depth :-)
How to Can Sweet Potatoes
Last Fall I found a great deal on organic sweet potatoes at Sam's Club of all places! They were about $1.52 a pound, so I bought 50 pounds!
By buying in bulk and canning them, I saved a ton as they are usually $3.65 a pound during the rest of the year. That's a 59% savings!!
While canning sweet potatoes does take about 3x longer to process per batch compared to carrots, it was worth it to save all that money and have such a nutrient dense food available to us during the year.
They especially come in handy during the holidays! Sweet potato casserole never tasted so good as when you use home canned sweet potatoes and a healthy topping of homemade marshmallows!
So when you're looking for great deals on food and you see those sweet potatoes on sale, grab them up and get to canning!
Home Canned Sweet Potatoes FAQ
Here are a few of the most common question I get about canning sweet potatoes at home!
Do I have to Use Syrup?
Nope! You can use just water instead, however, the sweet potatoes will be very bland with you use them later.
We like to use a light syrup for the least amount of sugar that will retain the flavor of the sweet potatoes.
Can I Use Something Other Than Sugar?
Actually, yes! You can use honey instead at the following ratio.
To make light syrup with honey: Mix 1/2 cups of honey with 4 cups of water and bring to a boil. Increase at this ratio as needed.
We use the same process for canning peaches in syrup.
Can I Use This Recipe for Yams?
Yep! Pressure canning yams and sweet potatoes are the same timings and method.
Are The Sweet Potatoes Mushy After Canning?
They have the same texture as boiled sweet potatoes, in my opinion.
So, they are not going to be the same texture as fresh baked sweet potatoes, but they are prefect for sweet potato casserole, blended soups, and so on.

I was wondering if it is okay to puree your sweet potatoes when canning. I would be using for sweet potato pies. Thank you for any help.
Victoria says
Hi Brenda!
No, it is not recommended to can puree of sweet potatoes, pumpkin, or other dense squashes. The reason being that the density of the puree can cause pockets of air that will grow bacteria. Instead, I can them in chunks and then puree before using. I hope that helps!
