Every time I think about pickling something, that skit from Portlandia comes to mind. “We can pickle that!” Anyone else? (You can watch it here if you have no idea what I’m talking about.)

Anywho, several years ago, I came across a recipe for Sweet Yellow Squash Pickles in one of my magazines. I tore it out and have hung onto it since then. Last week when I spotted a basket of yellow squash at the local farmers market, I decided it was finally time to give that recipe a try.

The whole idea of pickling squash was new to me, so I was curious how the pickles would taste. I couldn’t be more pleased with the results. They are delicious!

Why you’ll love this recipe

  • It’s a simple and healthy snack that comes together with about 20 minutes of hands-on time.
  • This is a fantastic way to use your bounty of summer squash from the garden, or you can purchase squash relatively cheap at a farmer’s market or grocery store.
  • I also love the red onions in this recipe. They are as wonderful as the squash. Pickling dulls the overly pungent taste of the onion, which might be why pickled onions have become sort of trendy these days. (They seem to be served on tacos a lot.)
  • As with their regular pickle cousins, these yellow squash pickles would be great served with a sandwich or included with other seasonal snacks on an appetizer board or jarcuterie. They would be perfect on my Summer Cheese Board!

Ingredients

You only need a handful of ingredients to make this yummy pickle recipe.

  • Yellow squash – you’ll want to cut them into about 1/4″ thick slices.
  • Red onion – slice it up thinly. The onion adds the perfect balance of flavor to the sweetness of the brine.
  • Sugar – yup, sugar. This is a sweet pickled recipe…trust me on this one. It’s delicious! If you prefer to have less sweet pickles, you can cut the amount down.
  • White vinegar – I recommend using white vinegar as it’s the most neutral-tasting variety. There are some recipes where you can swap out one vinegar for another, but unfortunately, this isn’t one.
  • Mustard seed – this is what gives pickles that zing that makes them so delicious!
  • Celery seeds – this small but mighty seed adds some lovely distinct flavor that can’t be replicated with anything else.
  • Dry mustard – again, mustard gives you the zing. Since this is a quick pickles recipe, I recommend using both the seeds and the powder.

Storage

You have 2 options for storing pickled squash.

Firstly, you could opt to store the jar in the fridge. It’ll last for about 30 days. However, you’ll need to chill the pickles at least 24 hours before serving.

Secondly, you can can the pickles according to the jar manufacturer’s instructions. This works well if you want to make a large batch and store it away in your pantry for later.

  1. Most people today do not know what a water bath is so they need to look up cold water bath canning process. Make sure if using a water bath process your jars are covered by at least 1 or 2 inches of water and start timing when the water starts boiling and process for about 10 to 20 minutes.

  2. What do you mean by “processed for long-term canning” – how do you do this? My partner and I just made this for the first time and we’ve put them in the fridge. Thank you!

    1. Canning is the process of heating up the jars (in a canner or hot water bath) in order to make contents shelf stable. There are a couple ways to do this. You can research the techniques online. However, I believe it needs to be done right after adding the ingredients to the jars.

  3. I have made two batches of these Pickle’s and the juice keep coming out cloudy. I even used pickling salt in the second batch. They taste wonderful they are just cloudy.

  4. I just did this recipe two days ago and it is absolutely delicious! My first time at canning anything!! Recently retired and started a garden! Did a small batch to see if we liked it and will be canning more for winter! Can you reuse the pickled juice? Seems like such a waste once the veggies are gone!

      1. Thanks :;) gunna give it a try today. I’ve always canned at sea level.. I moved to West Texas 2 years ago and my altitude is 3202 ft …. Needless to say I didn’t account for that last year so it was a total failure!!! I think I have my adjustments right this year … add 10 min extra to processing time … fingers crossed lol

  5. Hi, I was wondering if you rinse the salt from the squash and onions after letting them sit together in the salt or do you just drain them and move on to the next step?

      1. I ended up making these before I saw your reply. I rinsed them and they turned out wonderful!!! Hubby and I LOVE them!!!! I’ll be making many more batches with my loads of squash. And this time I will try NOT rinsing! Thanks for the wonderful recipe.
        Have you tried making them with apple cider vinegar? I might try a batch using ACV. I’ll let you know how they turn out!
