Why Making Canned Blueberry Pie Filling at Home Is Worth It
When you learn how to make canned blueberry pie filling, you gain control over flavor and ingredients.
Here’s why it stands out.

Usually, it’s just blueberries, sugar, lemon juice, and a little ClearJel or cornstarch.
3. It Saves Money and Prevents Waste
If you’ve ever had a bumper crop of blueberries, you know how fast they can go bad.
Learning how to make canned blueberry pie filling turns that surplus into jars you can enjoy all year.
That’s one of the best reasons to master how to make canned blueberry pie filling.
Ingredients for Canned Blueberry Pie Filling
Before you start making canned blueberry pie filling, gather everything you need.
Here’s what goes into a standard batch.
1. Fresh or Frozen Blueberries
You’ll need about 6 cups of fresh blueberries for a solid batch of canned blueberry pie filling.
Frozen berries work too — just thaw and drain them before making canned blueberry pie filling.
2. Sugar and Lemon Juice
Sugar sweetens and helps preserve your canned blueberry pie filling.
Lemon juice balances the flavor and boosts the acidity, which is key when making canned blueberry pie filling safely.
3. ClearJel or Cornstarch
ClearJel is the gold standard for thickening canned blueberry pie filling because it holds up to heat.
Cornstarch works if you’re eating the filling soon, but it’s not ideal for canning.
Use ClearJel when making canned blueberry pie filling you plan to store long-term.
4. Water or Blueberry Juice
A little liquid helps everything come together smoothly.
Some people use water, while others use extra blueberry juice for a richer canned blueberry pie filling.
Step-by-Step: How to Make Canned Blueberry Pie Filling
Here’s the process for how to make canned blueberry pie filling from scratch.
1. Prep Your Jars and Equipment
Start by sterilizing your jars and lids.
You’ll also need a water bath canner, a jar lifter, and a clean towel.
Getting this ready first makes the whole process of making canned blueberry pie filling run smoothly.
2. Make the Slurry
In a large pot, whisk your ClearJel or cornstarch with cold water until smooth.
This step prevents lumps when you start making canned blueberry pie filling.
3. Cook the Blueberries and Sugar
Add your blueberries, sugar, and lemon juice to the pot.
Bring everything to a boil, stirring gently so the berries stay mostly whole.
This is the heart of how to make canned blueberry pie filling — letting the fruit soften while the sugar dissolves.
4. Thicken the Mixture
Once boiling, stir in your slurry and cook for another minute or two.
The filling should turn glossy and thick.
If you’re wondering how to make canned blueberry pie filling that sets properly, this is the moment to get it right.
5. Fill and Process the Jars
Ladle the hot filling into your sterilized jars, leaving about an inch of headspace.
Wipe the rims, add the lids, and process in a boiling water bath for 30 minutes.
This final step seals your canned blueberry pie filling so it stays shelf-stable.
Tips for Perfect Canned Blueberry Pie Filling
A few extra pointers can make all the difference when you make canned blueberry pie filling.
1. Don’t Skip the Lemon Juice
Lemon juice isn’t just for flavor — it raises acidity, which keeps your canned blueberry pie filling safe.
2. Use ClearJel for Canning
Regular cornstarch breaks down during processing, leaving your canned blueberry pie filling runny.
ClearJel stays stable, so your canned blueberry pie filling keeps its texture.
3. Adjust for Altitude
If you live above 1,000 feet, you may need extra processing time.
Altitude affects how you make canned blueberry pie filling, so check your local guidelines.
So, How Do You Make Canned Blueberry Pie Filling?
Making canned blueberry pie filling comes down to combining blueberries, sugar, lemon juice, and ClearJel, then processing the jars in a water bath.
With the right ingredients and a little patience, you can enjoy homemade canned blueberry pie filling anytime you crave a slice of pie.
Now that you know how to make canned blueberry pie filling, grab some berries and get started — your future pies will thank you.
