This zucchini and green tomato relish recipe is the perfect way to use up the abundance of these vegetables that might be lingering in your garden. The relish is made with zucchini and green tomatoes (of course!) along with bell peppers, onions, pickling salt and spices, garlic and other spices, then canned in clean, glass jars. 

Get ready to make this recipe by prepping the zucchini, tomatoes, peppers, and onions and chopping them. We used the coarse grind of a stand mixer's grinder attachment to make this sweet relish. You can finely chop the vegetables if you don't have a grinder. Plan accordingly as the gound veggies need to sit in the pickling salt for three hours before mixing with the other ingredients and canning.

This is a great relish for hot dogs or burgers, or can be used as a condiment on sandwiches and salads, as a topping for potatoes, or on entrees. You can also use it to make tartar sauce. It's good with cheese too!


  • 2 1/2 pounds zucchini, ground, to make about 4 1/2 cups

  • 1 1/2 pounds green tomatoes, ground, to make about 2 cups

  • 3 large bell peppers, red and/or yellow, ground

  • 1 large onion, peeled, ground

  • 1/3 cup pickling or canning salt

  • 3 cups cider vinegar

  • 1 1/2 cups sugar

  • 1 tablespoon pickling spices

  • 1 teaspoon yellow mustard seeds

  • 1/2 teaspoon turmeric

  • 2 cloves garlic, finely minced

Steps to Make It

  1. Gather the ingredients.

  2. Put ground vegetables in a large nonreactive container with the pickling or canning salt; gently stir to combine.

  3. Top with about 3 cups of ice cubes. Cover and let stand for 3 hours. 

  4.  Drain and lightly rinse.

  5. In a large, nonreactive kettle combine the vinegar, sugar, pickling spices, mustard seeds, turmeric, and garlic. Bring to a boil. Then reduce heat to medium-low and simmer for 5 minutes.

  6. Add drained vegetable mixture and bring slowly to a boil. Simmer for 15 minutes.

  7. Pack into clean jars. Wipe rims with a clean damp cloth and seal with 2-part lids.

  8. Process in a boiling water bath canner for 10 minutes.


For the bell peppers, you can use all red, all yellow, or mix them up and use both for a more colorful accent to the relish.
