Ingredients for Sweet Zucchini Relish

This recipe yields seven 1-pint jars of relish, perfect for stocking your shelves or gifting.

• 12 cups shredded unpeeled zucchini
• 4 cups chopped onion
• 5 tablespoons canning salt
• 6 cups white sugar
• 2 ½ cups white vinegar
• 1 red bell pepper, chopped
• 1 green bell pepper, chopped
• 1 tablespoon cornstarch
• 1 ½ teaspoons celery seed
• ¾ teaspoon ground nutmeg
• ¾ teaspoon ground turmeric
• ½ teaspoon ground black pepper

Step-by-Step Instructions

1. Prepare the Zucchini Mix

In a large non-metallic bowl, combine the shredded zucchini and chopped onion. Sprinkle the canning salt over the mixture and use your hands to work it in evenly. Cover the bowl and refrigerate overnight to draw out excess moisture.

2. Rinse and Drain

The next day, drain the zucchini mixture in a colander. Rinse well with cool water and squeeze out as much liquid as possible. Set the zucchini aside.

3. Cook the Relish

In a large pot, combine the white sugar, white vinegar, chopped red and green bell peppers, and cornstarch. Stir in the celery seed, nutmeg, turmeric, and black pepper. Mix thoroughly, then add the drained zucchini.

Bring the mixture to a boil over medium-high heat, then reduce to medium-low and simmer for 30 minutes, stirring occasionally.

4. Sterilize Jars

While the relish is simmering, sterilize seven 1-pint jars and lids. This is crucial for safe long-term storage.

5. Pack and Process

Pack the hot relish into the sterilized jars, removing any air pockets and filling them to the top. Screw the lids on tightly.

Place a rack in the bottom of a large stockpot and fill halfway with boiling water. Carefully lower the jars into the water, making sure there’s 2 inches of water covering the tops. Add more boiling water if needed.

Cover and process for 30 minutes.

6. Cool and Store

Remove jars carefully and set them on a cloth-covered surface to cool. Once cool, press the center of each lid to ensure the seal is tight. If the lid pops up and down, the jar is not sealed properly and should be refrigerated and used within a few weeks.

Kitchen Equipment You’ll Need

• Large non-metallic mixing bowl
• Colander
• Large pot or Dutch oven
• Measuring cups and spoons
• Cheesecloth or clean kitchen towel (optional, for squeezing liquid)
• Canning funnel
• 7 one-pint canning jars with lids
• Jar lifter or tongs
• Large stockpot with rack (for water bath)
• Clean towels or wood surface (for cooling jars)

Storage Instructions

Properly processed and sealed jars of relish will last up to a year in a cool, dark pantry. Once opened, store in the refrigerator and use within 2-3 months.

If any jars didn’t seal correctly, refrigerate them and use within 2 weeks.

Recipe Variations and Substitutions

• Spicy Kick: Add 1–2 teaspoons crushed red pepper flakes or minced jalapeño for a spicier version.
• Sweeter Notes: Substitute part of the white sugar with light brown sugar or honey for a richer depth.
• Different Vinegar: Apple cider vinegar can be swapped in for a slightly fruitier tang.
• More Veggies: Add shredded carrots or chopped cucumbers for extra texture and color.

Feel free to experiment! Just maintain the vinegar and sugar ratios for safe canning.

FAQ About Sweet Zucchini Relish

Can I freeze this relish instead of canning it?

Yes, you can store it in freezer-safe containers. Leave about an inch of headspace for expansion. It will last about 6 months in the freezer.

Can I use yellow zucchini or summer squash?

Absolutely! Yellow zucchini or any tender summer squash will work just as well and add beautiful color variation.

Do I really need to refrigerate overnight?

Yes—this step helps draw out moisture from the zucchini and onions, improving the texture and shelf-life of your relish.

How do I know if my jars sealed properly?

Once cool, press the center of the lid. If it does not move, the seal is good. If it pops up and down, the seal failed—store the jar in the fridge and consume within a few weeks.

Can I reduce the sugar?

Reducing sugar is not recommended for canning, as it affects preservation. If you’d like a less-sweet version, make a smaller batch and store it in the fridge or freezer.
