If you’ve been wondering how to make canned pumpkin from scratch without any special equipment, you’ll be happy to know it only takes a few basic steps.
In this post, we’ll walk through how to make canned pumpkin from scratch, from picking the right pumpkin to processing and storing your homemade puree safely.
Let’s get to it.
How to Make Canned Pumpkin from Scratch
Learning how to make canned pumpkin from scratch starts with a few key steps:
1. Choose the Right Pumpkin
To make canned pumpkin from scratch that actually tastes good, skip the big carving pumpkin on your porch.
Those are watery and stringy, which makes for a bland puree.
Instead, grab a sugar pumpkin or pie pumpkin.
These are smaller, denser, and naturally sweeter, which is exactly what you want when you make canned pumpkin from scratch at home.
2. Wash, Cut, and Scoop
Rinse your pumpkin under cool water and pat it dry.
Cut it in half from stem to base, then scoop out the seeds and stringy pulp with a sturdy spoon.
Save those seeds if you like, since they’re perfect for roasting later.
3. Roast Until Tender
Place the halves cut-side down on a baking sheet lined with parchment paper.
Roast at 400°F for about 45 to 60 minutes, until the flesh pierces easily with a fork.
Roasting is the secret to making canned pumpkin from scratch taste rich and caramelized instead of watery and flat.
4. Scoop and Blend
Let the pumpkin cool until you can handle it comfortably.
Scoop the softened flesh away from the skin and drop it into a blender or food processor.
Blend until completely smooth, scraping down the sides as needed.
If the mixture seems too thick, add a tablespoon of water at a time until it reaches a puree consistency.
Tips for Making Canned Pumpkin from Scratch Taste Better
Once you know how to make canned pumpkin from scratch, a few small tricks make a big difference:
1. Drain Excess Liquid
Homemade pumpkin puree can hold more water than store-bought.
After blending, let it sit in a fine-mesh strainer lined with cheesecloth for 30 minutes so the extra liquid drips away.
This step is key when you make canned pumpkin from scratch for baking, because wet puree can ruin pies and breads.
2. Roast, Don’t Boil
Boiling pumpkin adds water and washes out flavor.
Roasting concentrates the natural sugars, so the canned pumpkin you make from scratch ends up sweeter and more flavorful without adding a thing.
3. Blend in Small Batches
Overloading your blender leaves lumps behind.
Work in small batches so your homemade canned pumpkin comes out silky smooth every time.
How to Store Homemade Canned Pumpkin
Knowing how to make canned pumpkin from scratch also means knowing how to keep it fresh:
1. Refrigerate in Airtight Jars
Pack your puree into clean glass jars and seal them tightly.
Homemade canned pumpkin keeps in the fridge for about 5 to 7 days.
2. Freeze for Longer Storage
For longer storage, portion the puree into freezer bags or ice cube trays.
Frozen canned pumpkin made from scratch lasts up to 6 months, and the cubes are handy for tossing into soups and smoothies.
3. Can It Properly if You Want Shelf Life
If you plan to actually can your pumpkin in jars, use a pressure canner and follow tested USDA guidelines.
Pumpkin is low-acid, so water bath canning isn’t safe for making shelf-stable canned pumpkin from scratch.

You make canned pumpkin from scratch by roasting a sugar pumpkin, scooping out the flesh, blending it smooth, and draining any excess liquid.
