How to Can Blueberries for Pie Filling Step by Step

Learning how to can blueberries for pie filling is easier than you think.
 
Just follow these steps carefully:
 

1. Gather Your Supplies

You’ll need clean quart or pint jars, lids, and bands, plus a water bath canner.
 
For the filling, grab fresh blueberries, sugar, lemon juice, and ClearJel (a modified cornstarch that holds up to canning heat).
 
Regular cornstarch breaks down during processing, so don’t substitute it.
 

2. Prep the Blueberries

Rinse your berries and pick out any stems or mushy ones.
 
For quart jars, aim for about 3½ cups of berries per jar.
 
If you want a smoother filling, lightly crush a third of the berries before packing.
 

3. Make the Syrup and Thickener

In a large pot, combine water, sugar, and ClearJel.
 
Whisk until smooth, then bring it to a boil, stirring constantly.
 
Add lemon juice at the end — it boosts flavor and helps the filling set.
 

4. Pack the Jars

Fill each hot jar with blueberries, leaving about an inch of headspace.
 
Ladle the hot syrup over the berries, making sure it covers them completely.
 
Run a plastic spatula around the inside to release air bubbles.
 

5. Process in a Water Bath Canner

Wipe the jar rims, add lids and bands, and lower the jars into boiling water.
 
Process pints for 30 minutes and quarts for 35 minutes, adjusting for altitude.
 
Once done, let the jars cool undisturbed for 24 hours and check that the lids sealed.
 

Tips for Perfect Canned Blueberry Pie Filling

Want your canned blueberry pie filling to taste like it came from a fancy bakery?
 
Keep these tips in mind:
 

1. Don’t Skip the ClearJel

ClearJel is the secret to a filling that thickens without getting gluey.
 
It stays stable through the canning process, unlike cornstarch or flour.
 

2. Add a Little Spice or Zest

A pinch of cinnamon or a bit of lemon zest can elevate your filling.
 
Just keep additions minimal so the blueberry flavor stays the star.
 

3. Use Firm, Ripe Berries

Overripe berries turn to mush once canned.
 
Pick berries that are ripe but still hold their shape for the best texture.
