How To Can Pumpkin Cubes

You can can pumpkin cubes at home with just a few simple steps, and it’s one of the easiest ways to preserve this fall favorite.
 
Whether you grow your own pumpkins or grab a few from the store, learning how to can pumpkin cubes gives you shelf-stable pumpkin ready for soups, pies, and stews anytime.
 
The process involves peeling, cubing, and pressure canning your pumpkin in a light syrup or water.
 
It’s safe, rewarding, and way better than store-bought cans.
 
In this post, we’ll walk through exactly how to can pumpkin cubes so you end up with jars of golden goodness that last for months.
 
Let’s dive in.
 

Why Can Pumpkin Cubes Instead of Puree?

You might wonder why you’d can pumpkin cubes rather than just making puree.
 
There’s a good reason for that.
 
When you can pumpkin cubes, you keep the pieces intact, and they hold their shape beautifully in recipes.
 
Puree is thicker and denser, which makes it harder for heat to penetrate evenly during canning.
 
Cubes, on the other hand, let the heat circulate properly, so you get a safer, more reliable result.
 
Plus, having pumpkin cubes on hand means you can toss them into curries, roast them, or mash them later if you want puree anyway.
 
It’s the more versatile option, and honestly, it’s just as easy once you get the hang of it.
 

How to Can Pumpkin Cubes Step by Step

Learning how to can pumpkin cubes comes down to a few key steps, and once you’ve done it once, it becomes second nature.
 
Here’s how to can pumpkin cubes the right way.
 

1. Pick the Right Pumpkins

Start with small, firm pumpkins that are fully ripe.
 
Sugar pumpkins or pie pumpkins work best because they’re sweeter and less stringy than the big carving kind.
 
Avoid any pumpkins with soft spots, cracks, or mold.
 
You want fresh, healthy fruit so your canned pumpkin cubes turn out perfect.
 

2. Wash, Peel, and Cube the Pumpkin

Give your pumpkins a good rinse under cool water to remove dirt.
 
Then cut off the stem, slice the pumpkin in half, and scoop out the seeds and stringy pulp.
 
Now peel the skin using a sharp knife or a vegetable peeler.
 
Cut the flesh into uniform one-inch cubes so they can properly during processing.
 

3. Blanch the Cubes

Before you can pumpkin cubes, you need to blanch them.
 
Drop the cubes into boiling water for about two minutes, then transfer them straight into ice water to stop the cooking.
 
This step helps them keep their texture and color.
 
Drain them well and pat them dry with a clean towel.
 

4. Pack the Jars

Fill clean, hot jars with your pumpkin cubes, leaving about one inch of headspace.
 
You can pack them tightly, but don’t crush them.
 
Then pour boiling water or a light syrup over the cubes, still keeping that one-inch headspace.
 
Use a bubble remover or a small spatula to release trapped air.
 
Wipe the rims clean and screw on your lids.
 

5. Pressure Can the Jars

This is the most important part of how to can pumpkin cubes safely.
 
Pumpkin is a low-acid food, so it must be processed in a pressure canner, not a water bath.
 
Process pint jars at 10 pounds of pressure for 55 minutes, and quart jars for 90 minutes, adjusting for altitude if needed.
 
Once the time is up, let the pressure drop naturally before opening the canner.
 

6. Cool and Store

Remove the jars and let them cool undisturbed for 12 to 24 hours.
 
You’ll hear that satisfying pop as the lids seal.
 
Check that each lid is concave and doesn’t flex.
 
Label your jars and store them in a cool, dark place.
 
Properly canned pumpkin cubes last up to a year or more.
 

Tips for Perfect Canned Pumpkin Cubes

A few extra pointers can make your canned pumpkin cubes even better.
 
Always use fresh, unblemished pumpkins for the best flavor and safety.
 
Don’t skip the blanching step, as it helps the cubes hold up during canning.
 
Stick to the tested processing times from reliable sources like the USDA or Ball Canning.
 
Never can pumpkin puree or mashed pumpkin, as it’s too dense for safe home canning.
 
And always check your jar seals before storing, discarding any that didn’t seal properly.
 

So, How to Can Pumpkin Cubes?

You can can pumpkin cubes by peeling, cubing, and blanching fresh pumpkin, then pressure canning the cubes in jars with boiling water or syrup.
 
It’s a straightforward process that rewards you with shelf-stable pumpkin ready for any recipe.
 
Now that you know how to can pumpkin cubes, you can enjoy your harvest all year long.
 
Grab some pumpkins, fire up that pressure canner, and get started.
 
Happy canning!
