Ingredients You’ll Need

4 cups grated zucchini
1 cup finely chopped onion
1 cup finely chopped bell pepper
2 cups sugar
1 cup apple cider vinegar
1 tablespoon mustard seeds
1 tablespoon celery seed
1 teaspoon turmeric
1 teaspoon salt

From Grating to Canning

Wash zucchini thoroughly.
Grate zucchini until you have about 4 cups and place in a large bowl.
Sprinkle 1 teaspoon salt over the grated zucchini and let it sit for 1 hour to draw out moisture.
While zucchini rests, finely chop 1 cup onion and 1 cup bell pepper.
After an hour, pour the zucchini into a colander and rinse under cold water to remove excess salt.
Gently press or squeeze the zucchini to remove as much liquid as possible.
In a large bowl, combine the drained zucchini, chopped onion, chopped bell pepper, 2 cups sugar, 1 cup apple cider vinegar, 1 tablespoon mustard seeds, 1 tablespoon celery seed, 1 teaspoon turmeric, and 1 teaspoon salt; mix until evenly combined.
Transfer the mixture to a large pot and bring to a boil over medium heat.
Reduce heat and simmer slowly for 20–30 minutes, stirring occasionally, until the vegetables are tender and the liquid has thickened to a slightly jammy consistency.
Remove the pot from heat and let the relish cool slightly so it’s safe to handle.
Ladle the hot relish into clean, sterilized jars, leaving about 1/2 inch headspace; wipe the rims clean and seal tightly with lids.
Optional: Process sealed jars in a boiling water bath for 10–15 minutes for long-term preservation.
Let jars cool completely on the counter before storing.

Serving and Flavor Tips

Sweet Zucchini Relish is so versatile—it really shines with grilled foods like chicken and beef, and it’s an easy way to dress up burgers and hot dogs. If you’re going meatless, try it with roasted veggies or on a cheese board. It’s also fantastic spooned onto crackers or toasted bread for a quick appetizer. Pair it with an ice-cold glass of iced tea or a crisp white wine for a perfect combo.

Use fresh zucchini for the best crispness and flavor; it really makes a difference.
Don’t forget the salting step—it pulls out extra water and locks in great texture and taste.
Feel free to tweak the sugar and vinegar amounts to match how sweet or tangy you like it.
Mark your jars with the date—you’ll thank yourself later for keeping track of freshness.

Skipping the drain means the relish might end up watery—not what you want!
Overripe zucchini can get mushy, so choose ones that are firm and fresh.
Let the relish cool before sealing jars to avoid a bad seal.
Don’t rush simmering; letting flavors meld is key to that perfect taste and texture.

Flavor Variations and Swaps

Want some heat? Add minced jalapeños or a pinch of red pepper flakes for a spicy twist.
For fewer calories or lower sugar, swap sugar with a sugar substitute like erythritol or stevia.
Try swapping bell peppers for other peppers or even some shredded carrots to change things up.
For fresh herbal notes, toss in some chopped dill or thyme.

Storage, Canning, and Reheating

Storing

If you’ve water-bath canned your relish, keep it in a cool, dark cupboard. Once you open a jar, pop it into the fridge where it will stay fresh for up to 2 months. If you skip canning and just refrigerate, it will last about a week in a sealed jar.

Reheating

Need to warm it up? Just spoon out what you need and heat it gently in a saucepan over low heat until warmed through. If you’re short on time, microwaving in a microwave-safe container for 1 to 2 minutes, stirring halfway, works great too.
