How to Can Shredded Zucchini Safely

When you can shredded zucchini, the key is understanding that zucchini is a low-acid vegetable.
 
That means you can’t just pop it in a water bath canner by itself without adding acid.
 
The safest way to can shredded zucchini is to either pickle it with vinegar or pressure can it following tested guidelines.
 
Many people ask, “Can I just water bath can shredded zucchini?” and the answer is only if you add enough acid, like in a pickled zucchini relish or zucchini pickles.
 
If you want plain canned shredded zucchini, you’ll need a pressure canner to reach the high temperatures required to kill botulism spores.
 

1. Choose the Right Zucchini

Start by picking firm, young zucchini that are free of bruises or soft spots.
 
Smaller zucchini tend to have better texture when canned, while giant overgrown ones can turn mushy.
 
Wash them thoroughly under cool running water to remove dirt and any garden debris.
 
You don’t need to peel them unless the skin is tough, but many people do peel before shredding for a smoother texture.
 

2. Shred and Prepare Your Zucchini

Use a box grater or a food processor to shred your zucchini.
 
If you’re planning to can shredded zucchini for baking, you might want to squeeze out some of the excess moisture first.
 
Excess water can make your canned zucchini watery, so place the shreds in a clean towel and wring them out gently.
 
Don’t squeeze them completely dry, though, because some moisture helps them pack nicely into jars.
 

3. Acidify or Pickle for Water Bath Canning

If you want to water bath can shredded zucchini, you must add acid.
 
A common approach is to make a pickling brine with vinegar, water, and salt, then pack your shredded zucchini into jars and cover it with the brine.
 
This turns your shredded zucchini into a tangy, pickle-like product that’s great on sandwiches or in salads.
 
Alternatively, you can make a zucchini relish with vinegar, sugar, and spices, which is another safe way to can shredded zucchini in a water bath.
 

4. Pressure Canning Plain Shredded Zucchini

For plain canned shredded zucchini without vinegar, you’ll need a pressure canner.
 
Pack the shredded zucchini loosely into hot, sterilized jars, leaving about 1 inch of headspace.
 
Add boiling water to cover the zucchini, leaving that 1-inch headspace.
 
Wipe the rims, add your lids, and process pints at 10 pounds of pressure for 25 minutes (adjust for altitude).
 
Quarts take about 30 minutes at the same pressure.
 
Always follow your pressure canner’s manual and tested recipes from a reliable source like the National Center for Home Food Preservation.
