How to Can Zucchini Pickles: Step by Step

Learning how to can zucchini pickles starts with a few key steps you’ll repeat whether you’re making bread and butter pickles or a dill version.
 

1. Choose and Prep Your Zucchini

The best zucchini for canning pickles are small to medium, about 6 to 8 inches long.
 
Larger zucchini have more seeds and water, which can make your pickles mushy.
 
Wash them well, then slice into 1/4-inch rounds or spears, depending on your preference.
 
You can also can zucchini pickles using a mix of yellow squash if that’s what you have on hand.
 

2. Make a Crisping Brine

Zucchini is softer than cucumbers, so a good trick when you can zucchini pickles is to soak the slices in a saltwater brine first.
 
Combine 1/2 cup of pickling salt with 4 cups of water and let the zucchini sit in it for 2 hours.
 
This draws out excess moisture and helps the pickles stay firm.
 
After soaking, rinse and drain the slices thoroughly.
 

3. Prepare Your Pickling Liquid

In a large pot, combine 3 cups of white vinegar, 3 cups of water, 2 tablespoons of pickling salt, and 2 tablespoons of sugar.
 
Add your spices: mustard seeds, celery seeds, turmeric, and peppercorns for bread and butter style.
 
For dill zucchini pickles, add fresh dill heads and garlic cloves to each jar instead.
 
Bring the liquid to a boil, then reduce to a simmer.
 

4. Pack the Jars and Process Them

Sterilize your jars, then pack the zucchini slices tightly, leaving about 1/2 inch of headspace.
 
Ladle the hot brine over the zucchini, making sure all the slices are covered.
 
Wipe the rims, seal with lids, and process in a water bath canner for 10 minutes for pint jars (adjust for altitude).
 
Once you know how to can zucchini pickles this way, you’ll never let a zucchini go to waste again.
 

Tips for the Best Canned Zucchini Pickles

If you want your canned zucchini pickles to turn out crisp and flavorful, these tips will help.
 

1. Use Fresh, Firm Zucchini

When you can zucchini pickles, fresh is best.
 
Pick your zucchini the same day you plan to can them if possible.
 
Avoid any zucchini that feels soft or has blemishes, as these won’t hold up well.
 

2. Don’t Skip the Saltwater Soak

This step is the difference between crunchy zucchini pickles and sad, soggy ones.
 
The salt draws out water so the brine can fully penetrate the zucchini, keeping them crisp.
 

3. Add a Grape Leaf for Extra Crunch

If you really want to can zucchini pickles that stay crunchy, tuck a fresh grape leaf into the bottom of each jar.
 
The tannins in grape leaves help prevent the enzymes that cause softening.
 

4. Let Them Cure Before Eating

Freshly canned zucchini pickles need about 4 to 6 weeks to develop their full flavor.
 
Patience pays off, and you’ll be rewarded with tangy, crisp pickles that taste amazing on burgers, sandwiches, or straight from the jar.
 

5. Store Them Properly

Keep your canned zucchini pickles in a cool, dark place like a pantry shelf.
 
Once opened, move them to the fridge and use within a few weeks.

If you want shelf-stable pickles, you must process the jars in a boiling water bath.
 
Otherwise, you’ll need to store them in the fridge and eat them within a few weeks.
 

3. Not Adjusting for Altitude

If you live above 1,000 feet, you’ll need to add extra processing time.
 
Check your local extension office for the correct times.
