Zucchini Salsa
Put your garden tomatoes and zucchini to delicious use with this sweet and smoky Zucchini Salsa. It’s a fresh salsa that yields 26 pints of home-canned goodness. I have been making this for 15 years.

Homemade sweet and smokey zucchini salsa takes any dish to the next level, especially when it’s home-canned. Can the full batch for your pantry or halve it for a refrigerator version that’s ready in minutes. Don’t have fresh garden tomatoes and zucchini? Farmer’s markets and farm stands have you covered!
Yes, canning takes time, but this recipe is proof that good things are worth the wait.

What is zucchini salsa?
This sweet-and-smoky salsa is made with freshly grated zucchini, onions, bell peppers, ripe tomatoes, and a warm blend of spices. The recipe includes full canning instructions for long-term storage, or you can easily halve it for a quick refrigerator version.
Versatile and utterly addictive, this salsa shines in countless ways. Slather it on burgers, layer it into sandwiches, or serve it alongside cream cheese for an irresistible dip. It’s summer captured in a jar: a truly fabulous condiment for any table.

Why you’ll love this homemade salsa
- While the process does require some time and effort, the end result is incredibly satisfying, and absolutely delicious.
- Each jar makes a thoughtful and memorable gift, perfect for holidays and other occasions.
- If you’re short on time, you can halve the recipe and skip the canning process entirely. Just store it in the fridge and enjoy it within two weeks.
Ingredients needed to make this zucchini salsa
- Veggies – This zucchini combines shredded zucchini, shredded onions, peppers (green and red), chopped jalapeno peppers, and chopped ripe tomatoes (skins on).
- Pickling salt
- Seasonings – Dry mustard, garlic powder, cumin, and red chili powder.
- Liquid smoke – This is optional, but it provides a nice smokey flavor.
- White vinegar – Vinegar (with at least 5% acidity) is crucial for safely preserving the salsa.
- Brown sugar – Balances the flavors.
- Cilantro – For a pop of freshness.
- Ground pepper – For a touch of warmth.
- Cornstarch – Thickens the salsa without altering the flavor.
- Tomato sauce – Adds concentrated flavor and thickens the salsa.
How do you make home canned salsa?
Combine veggies and let stand:
- For the first day, combine the zucchini, onions, green pepper, red pepper and the salt in a large mixing bowl.
- Mix together and cover. Let it stand overnight (the brining process).

Season and simmer:
- On the second day, rinse and drain the veggie mixture well.
- Place the mixture into a large pot then add the rest of the ingredients. Don’t forget the liquid smoke for a “smokey” flavor.
- Bring to a boil and simmer for 15 minutes.
Water bath the jars:
- Pour the salsa into sterilized jars and seal.
- Water bath the jars for 15 minutes.
- Remove jars and cool. Check lids for seal after 24 hours, by pressing on the center (it should not flex when pushed down).
Serving
This recipe yields 26 pints of delicious homemade salsa! Besides the normal way of enjoying with your favorite chips, you can pair this salsa with tacos, baked potatoes, burgers, sandwiches, substitute for half of the tomato sauce in meatloaf, dump it over scrambled eggs or omelets for breakfast or brunch, or add it to breakfast burritos!
Feel free to also enjoy this salsa with cream cheese as a tasty dip.

Sandy’s tips and substitutions:
- Storage: Unopened, sealed salsa can be stored in a cool, dark, and dry place for up to 12 to 18 months, but it will remain safe to eat for up to 2-3 years as long as the seal remains intact. Once opened, store in the fridge for up to 2 weeks.
- Freeze: For longer storage, pour the salsa into freezer-safe containers and freeze it for up to 6 months.
- Avoid skin irritation: Wear gloves when handling the jalapeños and make sure not to touch your eyes!
- Canning safety: When canning your zucchini salsa, it’s critical to follow a tested recipe. Do not alter the proportions of ingredients, especially the number of tomatoes, onions, or peppers, as this can affect the pH and safety of the product. Also, the acid (vinegar) is essential. Incorrectly canned salsa can pose a risk of botulism poisoning.
- Leave space in the jar: Leave 1/2-inch headspace when ladling the salsa into the jars. Headspace is the crucial air gap that allows food to expand and create a proper vacuum seal during processing, while also ensuring enough heat penetrates the jar to kill bacteria. Too little causes messy seal failures, and too much leaves excess air that prevents a strong vacuum.
Variations
- Sugar alternative: You can use something like monk fruit to replace the sugar, but I don’t recommend omitting the sugar entirely as it is essential for balancing flavors.
- Change the spice level: Safely change the ratio of jalapeno peppers to bell peppers as long as you keep the same total volume of peppers.
- Swap (some) of the vinegar: You can safely swap out half of the vinegar for an equal amount of bottled (not fresh squeezed!) lemon or lime juice.
- Smooth/blended zucchini salsa: Home canned salsa recipes are on the chunkier side because the density of the food is important when it comes to canning safety. So while I can’t recommend you blend this salsa before canning, you can blend this salsa right before eating-most immersion blenders fit perfectly in wide-mouth canning jars!

I have to leave comment even though I know this post is a few years old. I came upon your recipe in my attempt to use up the plethora of zucchini I had in my garden last year. I have made salsa for YEARS, but your recipe was the first my family requested I make again! It is delicious! A perfect blend of flavors and texture. So, I am canning another batch this year and hoping it will last long enoughuntil my zucchini come in next year. Thanks for sharing.
my husband smoked the tomatoes and spicy peppers (we used thai dragon and jalapenos on the trader smoker and skipped adding the smoke flavoring…. WOW such a great variation! This is our 3rd year making this recipe. It is a must- do for our summer garden and canning!
Sounds delicious Just one question Do you have to bribe overnight or could you just let sit for a few hours while you are getting everything else prepared
I always have followed the direction and brined overnight. But maybe try 4-6 hours? (I have not tried this though:) Good luck!
What’s the minimum amount of time to marinate the zucchini if you can’t do it overnight?
Maybe 4-6 hours? Although I have not tried it.
This is absolutely delicious! I substituted poblano peppers for the jalapenos for a milder flavor & got great reviews even from my friends who usually like the jalapeno varieties. We are making another batch tonight, the first batch we had cut into 1/3 of the recipe just to try it.
This is absolutely delicious! ! I have been canning salsa for years but was excited to try something new. Quick question : why do you leave the skins on the tomatoes?
Because it’s just another step to remove them (to blanch the tomatoes first). :)
Omg! This is wonderful! Been working on it for two days and ready to put in jars and process. The smokey flavor is so different with the cilantro really a hit. Thanks for sharing. Always looking for something different.
AWESOME! It’s one of our favorite recipes, Diane.
