This easy fermented salsa recipe is a delicious and healthy way to preserve the harvest and add probiotics to your diet. Tangy, fresh tomatoes, paired with veggies and zippy lime, make this fermented salsa the perfect accompaniment to your favorite Mexican dishes, or to eat straight up with chips.
Fermented Salsa = Preserving Summer
Summer is in full swing, and if you put in a garden, you are probably starting to get fresh tomatoes and herbs, which is perfect time for salsa.
I’ve shown you how to make fermented pickles, sauerkraut, and jalapeรฑos. We’ll follow the same process of making those fermented foods to make fermented salsa.
It is so not complicated. It is a process I put off for a long time because I thought it would be really difficult to ferment my own vegetables. But it is really as simple as adding salt water to vegetables, and then keeping them submerged below the brine. Plus a little time. That is essentially all it is.
Eating foods that have been fermented is a great way to add gut-healthy probiotics to your diet; it’s basically like taking a probiotic pill, but instead, you are making it yourself so your body can recognize it and use it. Healthy gut bacteria has been shown to help your immune system, decrease inflammation, and can help decrease the incidence of certain diseases. (source)
But making fermenting foods isn’t just amazing for your health. It is also good for preserving the harvest. There’s nothing like canning, which can keep food for years, but fermenting foods will keep them for the winter.
If you have a bumper crop of tomatoes, you can ferment them, and they will keep 3 months.
So, let’s say you have a huge harvest of tomatoes in August, and decide to make several jars of this homemade fermented salsa. Following this timeline, it will keep until November or early December.
If you were to make fresh salsa and didn’t ferment it first, you wouldn’t be able to do that. So this is a good way to preserve the goodness of your garden.
Tips for making fermented salsa:
This post contains affiliate links, which means I make a small commission at no extra cost to you. See my full disclosure here.
- You can use a starter from a previous batch of ferments; usually, I just use the straight salt water and allow the process to happen naturally.
- For this recipe I’m using salt, but you could use whey straight off of kefir or yogurt, water kefir, or a little juice from a previous ferment.
- If you don’t have weights, you could use a skin of an onion or a large slice of bell pepper to top the salsa and then pressing the salsa down well and submerging it below the brine.
- Add a few tsp of previous batch of ferments to your salsa to give it a probiotic boost, basically like a starter.
How does the fermentation process work?
Basically, you are allowing the good bacteria that is already present on vegetables to take over, while the salt inhibits the bad bacteria. The good bacteria then grow with a little time at room temperature.
After the good bacteria have grown (you can usually tell this by the vegetables tasting tangy – almost a little zippy), then you store it in a cool place to stall the good bacteria growth.
How long do fermented foods last?
Fermented foods that are properly prepared and stored in a cool, dark place (like the refrigerator) can last at least 4-18 months. This fermented salsa should last 3-4 months or longer. Look for any signs of mold, an even color throughout, and it still looks edible.
Use your nose to see if it still smells as it should, and doesnโt have a bad smell. Check to make sure the texture is still good, and not mushy. You can always taste it to make sure it tastes good.
Tools you will need:
Mason jar – I like the wide mouth mason jars for fermenting. This recipe uses a 24 oz wide mouth jar.
Fermentation lid – I like these silicone ones
Weight – These glass ones are my favorite.
Large bowl
Cutting board
Knife
Measuring spoon
Ingredients:
- 4 small tomatoes, around 2 cups – of course, this depends on the variety you grew. You could use two large tomatoes, or a bunch of cherry tomatoes.
- 1 bell pepper
- 1/2 white onion
- 1/2 lemon or lime – lime is more ideal.
- 1-2 cloves of garlic, depending on preference.
- 1 jalapeno – you can leave this out if you are making this for the kids.
- 1/4 cup chopped fresh cilantro
- 2 tsp salt

- Dice tomatoes- try to get as much of the juice in the bowl as possible. This will just help create more brine, which is important, since we want to keep the salsa submerged below the brine. If your tomatoes aren’t that juicy, you could always add water later.
- Chop remaining vegetables and add to the bowl.
- Squeeze in lemon/lime juice.
- Add 2 tsp salt and mix well.
- Add salsa to a wide mouth mason jar and place weight on top, making sure the vegetables are submerged under the brine. I like to push the weight down really hard to make sure.
- Cover jar with fermentation lid or a loose lid. You want the gases to be able to escape without allowing anything in, like gnats.
- Leave on the counter at room temperature for 2 days to allow the good bacteria to take over. Other ferments you leave out to ferment for a lot longer, but salsa only takes about 2 days to get that sour, tangy taste you are looking for. If your house is really warm, it may only take one day to ferment.
- Throughout the fermentation process, it is good to check your vegetables and make sure they are still submerged under the brine. Things will mold if they go above the brine or if there is not liquid at the top. If you find that you are losing liquid, or there wasn’t much to begin with, just add a little water, and keep an eye on it to make sure that the vegetables are staying submerged.
- Serve with chips, tacos, Mexican inspired dish. (i.e Mexican Hash with Avocado Crema, Pumpkin Sheet Pan Nachos, Healthy Quinoa Nachos Without Chips, etc)
Other ways to create a probiotic-rich brine for salsa:
Just pick one of these options. These are totally optional, and I really like to keep things simple, but there are a few other ways to create a brine. Personally, I like to just use salt for the sake of simplicity.
If you make your own yogurt or kefir, if you put it through a really tight cheese cloth and hang it up, the yellow liquid that comes out is called whey. You could also add that to your salsa to give it a good probiotic start.
Add a few tsp of water kefir.
Use a few tsp of a previous batch of ferments, like from homemade pickles.

So delicious! I had veggies piling up from the garden. This recipe was so easy to put together. The magic happened in just 2 days. Couldnโt be happier with the results. Thank you!
Is it ok to use hot peppers and no bell pepper?
Sure thing!
Hi! If I donโt have homegrown tomatoes, will grocery store tomatoes or canned diced tomatoes??? Sounds delicious, cant wait to try it
Yes, any fresh tomato will work!
I love this recipe. I have been making it for a few years now.
Is it okay to use crushed garlic in olive oil? I have always used fresh garlic for this recipe and there are bubbles after a few days. I made a batch a few days ago with the crushed garlic in olive oil and there are no bubbles… It smells and looks good.
Thanks!
I would not use it if it has been in olive oil.
My first batch was made with brine from fermented carrots and was bubbly when I placed it in the fridge 2 days later. It has that fizzy, fermented taste. The second one used fermented garlic brine, wasn’t bubby after 2 days and simply tastes like fresh salsa from the fridge. If it is not tangy is it not fermented? We actually prefer the taste of the second one but I am wondering if we aren’t getting the probiotic benefits.
That means it is probably not fermented all of the way.
Hi Lisa! I love all your content! Iโm wondering about the silicone fermenting lids: when the salsa is fermented after the 3 days can I then remove the fermenting lid and replace with a regular canning lid when the jar goes in the fridge?
Correct!
It’s great! My husband, the 2 older kids, and I all enjoyed the salsa. Our 4 year old didn’t try it. The jar won’t last much longer. For my personal preference I would like more tomatoes ands less onion. Would it be okay to do that if I keep the quantity of ingredients the same? This was my first time fermenting, so I don’t know what is safe to change.
Thanks Lisa!
Yes, that should be fine.
I live in a small apartment but you have inspired me to get a small plot in our community garden and try to enjoy homesteading as best as I can. Our little kitchen always has bread going and now fresh sourdough tortillas and salsa.
We love this salsa, so easy to make.
Can’t wait to try this recipe come August – it sounds fantastic. I was wondering if it would work using frozen tomatoes? I don’t really know much about fermenting, but have 2 5 gal bags of candland tomatoes in the freezer that I want to use up.
I think fresh tomatoes would work best!
