A sweet and tangy zucchini relish made with fresh zucchini, peppers, onions, apple cider vinegar, sugar, and spices. Perfect for hotdogs, burgers, cheese boards, and sandwiches, and ideal for preserving your summer harvest.

  • Total Time: 1 hour 10 minutes
  • Yield: 5 half-pint jars

Ingredients

3 cups grated zucchini (about 23 medium zucchinis)

3 cups chopped red or green pepper (about 23 whole peppers)

1 cup grated onion (about 1 large onion)

2 cups apple cider vinegar, divided

1 cup white sugar

1 tablespoon salt (not iodized)

1 tablespoon yellow mustard seeds

1/2 teaspoon celery seed

Pinch of red pepper flakes (optional)

Instructions

  1. Fill a water bath canner or large stockpot with water and bring to a boil. Wash 5 half-pint jars, lids, and rings in hot soapy water. Place jars in the water bath to heat and set aside lids and rings.
  2. In a large non-reactive pot, combine zucchini, pepper, and onion. Stir in 1 cup apple cider vinegar and bring to a simmer over medium heat. Cook for about 30 minutes until vegetables soften.
  3. Drain any excess vinegar and add remaining apple cider vinegar, sugar, salt, mustard seeds, celery seed, and red pepper flakes (if using). Bring back to a simmer and cook for 5 minutes.
  4. Ladle hot relish into heated jars, leaving 0.5 inch (12mm) headspace. Remove air bubbles, wipe rims clean, place lids, and screw on rings fingertip tight.
  5. Place jars in the water bath and process for 10 minutes. Turn off heat, remove lid, and let jars sit for 5 minutes before removing. Let jars sit undisturbed overnight.
  6. The next day, remove rings, check seals, wipe jars, label, and store in a cool, dark place.

Notes

  • For a spicier relish, add more red pepper flakes or a chopped jalapeƱo.
  • You can substitute apple cider vinegar with white wine or rice vinegar for a different flavor.
  • For a sugar-free version, replace white sugar with a sugar alternative like stevia or monk fruit.
  • Properly sealed jars can last up to a year when stored in a cool, dark place.
