How to Make Home Canned Pumpkin!

(and winter squash, like butternut)

You probably take canned pumpkin for granted.  You're there, the can is there, there's a pumpkin on the label... open it and mix it up with spices to make a pie, right.  Ah, but a pumpkin pie, pumpkin soup, pumpkin bread made from a fresh pumpkin tastes so much better than the glop that was processed last year! Canning pumpkin at home is easy! Here's how to do it, complete instructions in easy steps and completely illustrated. And it is much easier than you think, using my "patented" tips and tricks!  You can freeze it for later use, too. One important fact: you can the pumpkin as cooked cubes, not a puree nor a ready pie filling.  And you must use a pressure canner, not a water bath canner. See this page for the safety reasons why.

Directions for Home Canning Pumpkin from Scratch

Ingredients and Equipment

  • a pie pumpkin (see step 1)
  • A sharp, large serrated knife
  • an ice cream scoop
  • a large microwaveable bowl or large pot
  •  Pressure canner
  • Canning jars with rings and new lids

Recipe and Directions

Step 1 - Get your pie pumpkin

"Pie pumpkins" are smaller, sweeter, less grainy textured pumpkins than the usual jack-o-lantern types.  grocery stores usually carry them in late September through December in the U.S.   Note: the Libby's can of cooked pumpkin is just there for reference - it is the small can, so that gives you an idea of the size of a typical pie pumpkin.  They're only about 8 inches in diameter.
Just like selecting any squash, look for one that is firm, no bruises or soft spots, and a good orange color. Pumpkins and squash should have a hard rind and stringless, mature pulp of ideal quality for cooking fresh. You can also use these directions for any hard winter squash, such as butternut, hubbard, turban, etc.
Yield: Pie pumpkins are small, usually only 6 inches in diameter.  You can usually obtain about 2 or 3 cups or puree  per pumpkin. An average of 16 pounds of raw pumpkin is needed per canner load of 7 quarts.  Or an average of 10 pounds per canner load of 9 pint jars.  This works out to an average of 2¼ pounds per quart.

Step 2 - Prepare the pumpkin for cooking

Wash the exterior of the pumpkin in cool or warm water, no soap.
Cut the pumpkin in half.  A serrated knife and a sawing motion works best - a smooth knife is more likely to slip and hurt you!


Step 3 - Scoop out the seeds...

And scrape the insides.  You want to get out that stringy, dangly stuff that coats the inside surface.  I find a heavy ice cream scoop works great for this.
Note: SAVE THE SEEDS:
The seeds can be used either to plant pumpkins next year, or roasted to eat this year! Place them in a bowl of water and rub them between your hands.  then pick out the orange buts (throw that away) and drain off the water. Spread them out on a clean towel or paper towel to dry and they're ready to save for next year's planting or roast.  Click here for roasting instructions! (opens in a new window)

Step 4 - Cooking the pumpkin

There are several ways to cook the pumpkin;  just choose use your preferred method.  Most people have microwaves, and the use the least energy, so I'll describe that here. But others make good arguments in favor of using a pressure cooker, steaming on the stovetop or baking in the oven. I’ll describe microwaving here, and at the end of this document, I’ve included alternative instructions to replace step 4, if you’d rather use a different method.

Put it in a microwaveable bowl

Remove the stem, and put the pumpkin into a microwaveable. You may need to cut the pumpkin further to make it fit.  The fewer the number of pieces, the easier it will to scoop out the cooked pumpkin afterwards.
Put a couple of inches of water in the bowl, cover it, and put in the microwave. 

Step 5 - Cook the pumpkin until it just starts to get soft

Cook for 10 minutes on high, check to see if it is soft, then repeat in smaller increments of time until it is soft enough to separate (peel by hand) the skin easily, but the pumpkin is not yet mushy..  Normally it takes 20 or 30 minutes in total. Caution: Do not mash or puree.

 

 

Or steam on the stovetop

Step 6 - Peel

You should be able to easily peel off the skin using a blunt knife in one hand and an oven mitt (I like the waterproof silicone type) in the other.

Step 7 - Cut into 1 inch cubes

Note: there are many varieties of pumpkin and some make better pies that other (due to sugar content, flavor, texture and water content.  Drier, sweeter, fine-grained pies; the small (8" across) ones called "pie pumpkins" are best.  If your pumpkin is much more watery than the puree in the photo at right (there should not be any free water), you may want to let it sit for 30 minutes and then pour off any free water.  That will help prevent you pie from being too watery! Beyond, that, I have not found that the water makes a difference - I wouldn't be TOO concerned about it!

 

Step 7 - Pack the jars

Step 8 - Put the jars in the canner and the lid on the canner (but still vented)

Using the jar tongs, put the jars on the rack in the canner.  By now the water level has probably boiled down to 3 inches.  If it is lower than that, add more hot tap water to the canner. When all the jars that the canner will hold are in, put on the lid and twist it into place, but leave the weight off (or valve open, if you have that type of pressure canner). And, yes, you MUST use a pressure canner!!!

Step 9 - Let the canner vent steam for 10 minutes

Put the heat on high and let the steam escape through the vent for 10 minutes to purge the airspace inside the canner.

Step 10 - Put the weight on and let the pressure build

After 10 minutes of venting, put the weight on and close any openings to allow the pressure to build to 11 to 13 pounds in a dial-type gauge canner - shown in the photos (or at 10 to 15 pounds pressure in a weighted gauge canner.

 

Step 11 - Process for the required time

Once the gauge hits 11 pounds (or 10 pounds in a weighted gauge type), start your timer going - for 65 minutes for pint jars and quarts for 75 minutes.  Adjust the heat, as needed, to maintain 10 pounds of pressure. Remember - this is an estimated time based on cubed squash - I still recommend you put the finished jars in the refrigerator afterwards.
Pressure required depends on the altitude where canning is being done. Note: the chart below will help you determine the right processing time and pressure, if you are above sea level.
It is important to learn how to operate your pressure canner by reading the owner's manual that came with your particular canner. If you can not find your owner's manual, you can obtain find one online: Here is where to find some common manufacturer's manuals:
or by contacting the company that made your canner. Give the model number to the manufacturer, and they will send you the right manual. More information about pressure canners and a variety of models you can order.

Hot Pints 55 min 10 lb 15 lb
Quarts 90 10 15

Step 12 - Turn off the heat and let it cool down

When the processing time from the chart above is up, turn off the heat, and allow the pressure canner to cool and the pressure to drop to zero before opening the canner.  Let the jars cool without being jostled. After the pressure drops to zero (usually, you can tell but the "click" sound of the safety release vents opening, as well as but the gauge.  Let the pressure in the canner drop to zero by itself. This may take 45 minutes in a 16-quart canner filled with jars and almost an hour in a 22-quart canner. If the vent is opened before the pressure drops to zero OR if the cooling is rushed by running cold water over the canner, liquid will be lost from the jars. Too rapid cooling causes loss of liquid in the jars!

Step 13 - Remove the jars

Lift the jars out of the water and let them cool on a wooden cutting board or a towel,  without touching or bumping them in a draft-free place (until warm to the touch). You can then remove the rings if you like, but if you leave them on, at least loosen them quite a bit, so they don't rust in place due to trapped moisture. Now store them in a cool dark area, like a basement, or pop them into the fridge and you're done!

To use the cooked pumpkin

The pumpkin is now cooked and ready for the pie recipe. Just drain the water and puree the contents, then use as any cooked pumpkin! How about ...

Alternative Cooking methods for step 4

If you don’t have a microwave, or prefer another method, try these:Stovetop steaming – Place your steaming basket or grid in the bottom of a large pot.  Put enough water so it won’t boil dry in 20 minutes, and yet is not so high that the pumpkin is touching the water level. You may need to add more water during the cooking. Add the pumpkin prepared in step 3, and get the steamer going. The cooking time is only between 8 and 12 minutes, depending on the range (gas or electric), and the pumpkin literally falls off the skin.
Pressure cooker – Place your grid in the bottom of the pressure cooker.  If your pressure cooker came with directions, follow those for pumpkin and/or winter squash, like butternut squash.  If, like most people, you’ve long since lost the directions, try this: Add enough  water to just touch the bottom of the grid or shelf that you will place the pumpkin on. Add the pumpkin prepared in step 3, put the lid with the gasket, the weight and anything else your cooker requires in place, and turn the heat on  high. Once it starts hissing, turn it to medium or medium high.   The cooking time should only be about 10 minutes,  and the pumpkin should literally fall out of its skin.
Oven – You can also bake the prepared pumpkin in the oven, just like a butternut squash.  This method takes the longest. Just put the prepared pumpkin in an ovenproof container (with a lid), add about 3 cups of water to help prevent it from drying out and pop it in an 350 F (200 C) oven. It normally takes about 45 minutes to an hour; just test it periodically by sticking it with a fork to see if it is soft!
