You make squash relish by combining chopped squash with onions, peppers, vinegar, sugar, and a few key spices, then cooking it down into a sweet and tangy spread.
It’s one of those old-fashioned recipes that turns an abundance of garden squash into jars of gold you can enjoy all year long.
If you’ve ever wondered how do you make squash relish, the good news is that it’s way easier than you might think.
You don’t need fancy equipment or years of canning experience to make squash relish that tastes like it came from your grandmother’s kitchen.
In this post, we’ll walk through how to make squash relish step by step, including the ingredients you’ll need, the cooking process, and how to preserve it properly.
Let’s dive in.
How Do You Make Squash Relish? The Basic Process
When you make squash relish, the process boils down to three simple stages.
You prep and chop your vegetables, you simmer everything in a vinegar and sugar brine, and then you either refrigerate or water-bath can your jars for long-term storage.
That’s really all there is to it.
The result is a versatile condiment that’s sweet, tangy, and slightly crunchy, perfect for topping hot dogs, burgers, beans, or even scrambled eggs.
Learning how to make squash relish is also a fantastic way to use up those giant zucchini or yellow squash that seem to appear overnight in your garden.
1. Gather Your Ingredients
To make squash relish, you’ll need about eight cups of diced squash, which works out to roughly four pounds.
Yellow squash, zucchini, or a mix of both will work beautifully.
You’ll also need two large onions, two green bell peppers, and two red bell peppers, all finely chopped.
For the brine, grab three cups of white vinegar, two and a half cups of granulated sugar, one tablespoon of salt, one teaspoon of celery seed, and one teaspoon of mustard seed.
Some folks like to add a teaspoon of turmeric for color, and a pinch of red pepper flakes if they want a little heat.
2. Prep and Salt the Squash
Start by dicing your squash into small, uniform pieces.
If you’re making squash relish with large zucchini, scoop out the seeds first so your relish doesn’t turn out watery.
Toss the diced squash and onions with a couple tablespoons of salt in a large bowl.
Cover it and let it sit for at least two hours, or overnight if you have time.
This step pulls excess moisture out of the squash, which is the secret to making squash relish that stays crisp instead of turning to mush.
After salting, drain the mixture and rinse it well under cold water.
Squeeze out as much liquid as you can using a clean kitchen towel or paper towels.
3. Simmer the Relish
In a large pot, combine your vinegar, sugar, and spices.
Bring that mixture to a boil, stirring until the sugar dissolves completely.
Add your drained squash, onions, and peppers to the pot.
Reduce the heat and let everything simmer for about ten to fifteen minutes.
You want the vegetables to soften slightly but still hold their shape.
If you’re asking how do you make squash relish thick enough, the answer is patience.
Letting it simmer a bit longer allows the liquid to reduce and the flavors to deepen.
Tips for Making Squash Relish Taste Amazing
Making squash relish that people rave about comes down to a few small details.
Get these right and your homemade squash relish will outshine anything from the store.
1. Don’t Skip the Salt Soak
The salt soak is what separates good squash relish from great squash relish.
Squash is naturally watery, and if you skip this step, your relish will end up soupy.
The salt draws out moisture so the final product stays crunchy and holds together on a bun.
2. Balance Sweet and Tangy
The beauty of squash relish is the sweet-and-sour flavor, so taste as you go.
If it’s too tangy, add a little more sugar.
If it’s too sweet, splash in a bit more vinegar.
When you make squash relish at home, you get to adjust it exactly to your liking.
3. Add a Little Heat if You Like
Classic squash relish is mild, but there’s no rule saying you can’t spice it up.
Toss in a chopped jalapeƱo or a pinch of cayenne pepper for a version that kicks back.
Just remember that a little goes a long way, especially after the relish sits and the flavors meld.
How to Store and Preserve Squash Relish
Once your relish is cooked, you’ve got two options for storing it.
For short-term use, spoon the hot relish into clean jars and let them cool.
Then pop them in the fridge, where your squash relish will keep for about three to four weeks.
For longer storage, you’ll want to water-bath can your jars.
Fill sterilized jars with the hot relish, leaving half an inch of headspace.
Wipe the rims, seal with lids, and process the jars in a boiling water bath for fifteen minutes.
Properly canned squash relish will last on your pantry shelf for up to a year.
1. Use the Right Jars and Lids
Always use mason jars designed for canning, not repurposed jars from the grocery store.
Those commercial jars aren’t made to handle the heat and pressure of water-bath canning.
And never reuse old lids, since the sealing compound only works once.
2. Check Your Seals Before Storing
After your jars cool, press the center of each lid.
If it doesn’t pop up and down, the seal is good.
Any jars that didn’t seal properly should go straight into the fridge and get eaten first.
