How to Can Blueberries for Pie Filling: Step by Step

Learning how to can blueberries for pie filling comes down to a few key steps, and once you’ve done it once, it becomes second nature.
 

1. Gather Your Ingredients and Equipment

To can blueberries for pie filling, you’ll need about 6 quarts of fresh blueberries, 6 cups of sugar, 2 ¼ cups of Clear Jel, 7 cups of water, and ½ cup of lemon juice.
 
You’ll also need a water bath canner, mason jars, lids, and bands.
 
Clear Jel is important here because it’s the only thickener that’s safe and reliable for canning pie filling.
 
Cornstarch and flour break down during processing, so don’t use them.
 

2. Prep the Blueberries and Jars

Rinse your blueberries well and pick out any stems or mushy ones.
 
Meanwhile, wash your jars in hot soapy water and keep them warm until you’re ready to fill them.
 
Simmer your lids in a small pot of hot water to soften the rubber seals.
 

3. Make the Syrup Base

In a large pot, combine the sugar, Clear Jel, and water.
 
Whisk it together so there are no lumps, then cook over medium-high heat, stirring constantly until the mixture thickens and starts to bubble.
 
This is the part where you can blueberries for pie filling properly, because a smooth, thick syrup coats every berry evenly.
 

4. Add the Blueberries and Lemon Juice

Once your syrup is thick and bubbling, gently fold in the blueberries and lemon juice.
 
Stir carefully so you don’t crush the berries, and bring the mixture back up to a gentle boil.
 
Let it bubble for about a minute, then turn off the heat.
 

5. Fill and Process Your Jars

Ladle the hot filling into your prepared jars, leaving about an inch of headspace.
 
Wipe the rims clean, place the lids on, and screw the bands down fingertip-tight.
 
Process the jars in a boiling water bath canner for 30 minutes, adjusting for your altitude if needed.
 
When you can blueberries for pie filling this way, the heat seals the jars and makes them shelf-stable for up to a year.
 

Tips for Perfect Canned Blueberry Pie Filling

A few small details make a big difference when you can blueberries for pie filling.
 

1. Don’t Skip the Lemon Juice

Lemon juice isn’t just for flavor.
 
It adds acid, which helps the filling stay safe and brightens the color of the berries.
 
Skipping it can leave you with a dull, flat-tasting filling.
 

2. Use Clear Jel, Not Cornstarch

We mentioned this already, but it’s worth repeating.
 
Clear Jel is the gold standard when you can blueberries for pie filling because it thickens without turning gummy or cloudy.
 
Cornstarch will break down in the canner and leave you with runny filling.
 

3. Check Your Seals Before Storing

After your jars cool, press the center of each lid.
 
If it doesn’t pop up and down, the jar is sealed.
 
Any jars that didn’t seal should go straight into the fridge and be used within a couple of weeks.
