My first foray into refrigerator pickles was a seriously momentous occasion that took place just about 3 years ago. That post with my son, Ryan, remains one of my favorite of all time and the resulting Sriracha Refrigerator Pickles were a big success. I’ve had some very nice feedback from those of you who’ve made them – thank you very much! My pickle loving heart appreciates each and every one of your comments.

I’ve long heard that zucchini is fabulous pickled. This little kitchen project has been on my to-do list since last summer. I’m so glad I finally got around to trying to out because we are completely hooked. We’ve become a house full of die-hard Zucchini Pickle fans.

Due to the overwhelming response I received on my Italian Stuffed Zucchini Boats, I’m guessing that more than a few of you might have piles of these versatile veggies lying around your kitchen. I hope you’ll find some time to give this recipe a try. Try the Zucchini Boats too… oh my gosh, yum!

Ingredient Notes

Three open mason jars full of Refrigerator Zucchini PIckles.

Zucchini vs. Cucumber

Zucchini contains less water than cucumbers so less water is pulled from the zucchini during the brining process. This means there is less dilution of the brine. For this reason, I’ve upped the water to vinegar ratio as compared to the brine for my Sriracha Refrigerator Pickles. Zucchini won’t shrink and settle as much as cucumbers, so don’t feel the need to pack the jars too tightly. Fill them up close to the top, leaving about ½-inch headspace.

Vinegar

My vinegar of choice for this recipe is basic distilled white vinegar ( 5% acid). It’s bright, clear, and doesn’t affect the color of the finished product. It also makes for an excellent brine. It’s very inexpensive and I always have a big jug of it in my pantry.

Salt

It’s important to use coarse sea salt or kosher salt that does not contain iodine. Iodized salt can discolor your pickles and result in a cloudy brine.

Zucchini Pickling Spices

All pickles start with a seasoned brine of some sort. For the zucchini I went with black peppercorns, mustard seed, and dill seed. All of these should be readily available in the spice section of most grocery stores. I also threw in some halved cloves of garlic.

The pickling spices and garlic cloves in the bottom of three empty mason jars.

How to Make Refrigerator Zucchini Pickles

  1. Instead of adding the seasonings to the brine, I place them into the jars right off the bat. This ensures an even amount ends up in each jar. It works beautifully.
Slices of zucchini and sprigs of fresh dill are placed in the mason jars.

Filling the Jars

  1. Fill the jars with your sliced zucchini and a couple of sprigs of fresh dill.

Ingredient Swap

If you don’t have any fresh dill on hand, you can substitute ½ teaspoon dill seed per jar. You’ll still get that nice, dilly flavor.

The brining liquid is poured into the mason jars.

Zucchini Pickle Brine

  1. The water, distilled white vinegar, sugar, and coarse sea salt are brought to a boil. Then, the hot brine is poured right into the jars over the zucchini.
  2. Tightly secure the lids and shake the jars. Allow them to cool slightly on your kitchen counter for about 30 minutes. Then, refrigerate the pickles for 24 hours or more before eating.

Other Important Notes

  • Pretty pickles: I made my chips pretty by slicing the zucchini with my Wavy Knife.
  • Pre-cooking zucchini: I’ve seen other methods that instruct you to par-boil the zucchini or soak it in a salt water solution to soften it before adding the brine. I don’t recommend this. The zucchini will soften just the right amount from a good soak in the hot brine. Within 24 hours or less you’re going to have perfectly crisp-tender Zucchini Pickles on your hands. I believe this method makes it easier to avoid the dread of droopy, overly soft pickles. Nobody wants that!
  • Water bath canning: This recipe is strictly intended to be a refrigerator pickle recipe. Do not attempt to use it for water bath canning as it will not result in shelf-stable jars of pickles.
  • Storage: The pickles must be kept refrigerated and will stay fresh and tasty for 2 weeks or more.

    This recipe is seriously amazing! I wasn’t able to find dill seeds in my local area so I omitted them completely and it still came out wonderful. These taste identical to dill pickles and I am hooked!

    1. Valerie Brunmeier says:

      This is great to hear! Thanks, Kaisy. 🙂

  2. KATHY CHACE says:

    Our family loved these zucchini pickles!! Thank you for sharing! We will definitely be making these again!!😋

  3. Kathy says:

    So good! Crisp and delicious. They went great on a charcuterie board. Looking forward to trying them on a burger. I little on the mustardy side, but I like that.

  4. Linda P says:

    Do I have to use sugar? Will they be OK without?

    1. Valerie Brunmeier says:

      Hi Linda. The sugar helps balance the vinegar and without it, I’m afraid the brine would be very strong. I wouldn’t eliminate it altogether.

  5. Elizabeth says:

    I was worried because the zucchini looked like it was “soft” in the brine but after 24 hours they were perfect and crunchy. I cannot believe this was so easy and turned out. I added a dried pepper and they are spicy, sweet, garlicky.

  6. john wilson says:

    is there a substitute for the dill seed, that is hard to find in the stores

  7. LeAnn says:

    5 stars
    Wonderful recipe for these pickles! thank you! My family all loved them.
    I was wondering can you reuse the brine for another batch?

  8. Kristin says:

    5 stars
    This has been a huge hit in my neighborhood. I’ve made with both cucumbers and zucchini.

    I’d like to make a batch where I actually can in a water bath. Would you recommend I use canning/pickling salt? If so, how much?

    I’m new to this whole canning thing!

    1. Valerie says:

      Hi Kristin. In order to convert to a water bath canning recipe it would require testing. So glad you are enjoying the recipe!

  9. Diane says:

    Can you substitute anything other than mustard seeds?

  10. Amy says:

    5 stars
    This pickling recipe is fantastic! The ingredients amounts are on point. I’ve made so many batches with zucchini from my garden. My 12 year old son loves them!

  11. Heidi says:

    How long will these last (stay crisp, and able to be eaten)?

    1. Heidi says:

      I see now 😎

  12. Betty Schiller says:

    I switched the amounts of sugar and. Salt around as we don’t care for a sweet taste. They are absolutely awesome. Have made three batches already.

    1. Valerie says:

      So great to hear!

      We prefer them that way as well. In our case we kept the salt the same and omitted the sugar. I think they are great this way. We also cut up some of those mini-peppers that taste like bell peppers and added those to the jar. You can catch just a hint of the peppers flavor in the zucchini. It also adds some color to the jar as the peppers are usually red, yellow and orange.
