Zucchini Mustard Relish

This Zucchini Mustard Relish is for all the people wondering what to do with their bumper crop of zucchini this Summer! Perfect on hamburgers or hot dogs or enjoy with sausage.

My sister introduced me to this relish. It’s a great way to use up your bumper summer crop of zucchini! So if you have lots of zucchini to use up, this is for you. It uses up a lot of zucchini and reduces it to a few lovely jars of preserves to be enjoyed over the winter.

Zucchini is combined with onions, red peppers, chili pepper flakes (for a touch of heat), vinegar and mustard, for a relish that is perfect with sausage, pork or on hot dogs or hamburgers. (We love it with sausage, especially!)

Cook’s Notes for Zucchini Mustard Relish

This is a super easy relish, with just a bit of chopping to do, but honestly, I find chopping very therapeutic. After that, it’s a quick cook and in to the jars. If you’re starting out with a particularly large zucchini (the one I used was about 5 lbs.!), you’ll probably want to remove some of the seeds. Otherwise, with a normal sized one, you’re good to leave them in. You can also chop the zucchini by hand, if you don’t have a processor.

  • I have made 2 batches of this already this summer. I like to dip pretzels in it, and my husband likes it mixed in with his scrambled eggs. Yummy!

  • Even though we don’t garden, we’ve got zucchini comin out of our ears! Gifts from friends :) This sounds perfect for sausage (or sandwiches, or anything!). My mother has all the canning supplies, and since we haven’t canned our usual tomatoes this year, I think we should try this instead. Delicious!

    • Same here Sophie. I was gifted a monster zucchini. I cut 3 lbs. worth out of it and still had some left! This stuff is addictive. We can’t eat sausage anymore without a bit of mustard pickle on the side. Hope you get a chance to try it.

I love hearing from you, so if you have a question or something isn't quite clear, I'm happy to help. If you made this recipe, I'd love to know how you liked it ~ Jennifer
