Relish is one of our favorite homemade condiments. Since we grow dozens of pepper plants each year, we end up making a lot of homemade spicy jalapeño relish.

In this article, I’ll share our simple jalapeno relish recipe using just 7 ingredients. It is tangy, sweet, and will last for weeks in the refrigerator. You can even can it for long term storage!

Ingredients for Jalapeno Relish

At its most simple, relish is made up of cooked and pickled chopped vegetables (and sometimes fruits) to make a tasty condiment. You can ferment your ingredients to make relish, but I prefer to use vinegar for a quicker method.

Jalapeno relish ingredients

This recipe is all about the jalapeños. There is a reason they dominate supermarkets in the US – they are smokey, crunchy, and have the perfect amount of heat for most people.

Ingredient List:

  • Jalapeño. These spicy green peppers are easy to find and make up the majority of this recipe. If you want an even spicier relish, feel free to throw in something hotter such as a cayenne or even a habanero or ghost pepper.
  • Red onion. After much experimenting with simple relish recipes, red onion (or shallot) makes the perfect compliment to the rest of the ingredients. They also add a beautiful color to the finished product.
  • Sugar. This is a sweet relish, so sugar is required. I experimented with less sugar and it just isn’t quite the same. Of course feel free to use a sugar-free substitute at the appropriate amount.
  • Salt & pepper. Just a touch of salt to make the flavors pop, and a few cracks of freshly ground black pepper.
  • White vinegar. White vinegar allows the natural colors of the jalapenos to shine in this relish. You could use white wine vinegar instead if you prefer the flavor.
  • Celery seed. While fresh celery is perfectly usable in as a substitute, a small amount of celery seed adds a surprising amount of taste. Plus, we’ll be toasting the seeds to bring out the oils and maximize flavor.

With a star-studded ingredient list like this, I’m sure you agree that this can’t possibly be bad (and you’re right, it is delicious). However, feel free to use this as a base and tinker to your liking with other herbs, spices, and fresh ingredients.

Tip: Other common ingredients used for relishes include cucumber, mustard seeds, turmeric, ginger, and garlic.

How to Make Jalapeno Relish

The most important thing to get right is the proportion of fresh ingredients to liquid ingredients. The amount of sugar you add can be varied to your sweetness preference.

Ingredients:

  • 2 cups jalapeños, finely diced (about 12 peppers)
  • 1 cup red onion, finely diced
  • 3/4 cup white sugar
  • 1 tsp salt
  • 12 cracks black pepper
  • 1 cup white vinegar
  • 1 tsp celery seed, toasted (substitute 1/4 cup fresh celery, finely diced)

*Makes ~2 cups finished relish

Time needed: 15 minutes

How To Make Jalapeno Relish

  1. Finely dice peppers and onion.

    Remove the stems from the jalapenos. Slice lengthwise into thin sticks, then chop into tiny cubes, about 1/8-1/4″ thick. Finely dice the red onion the same way.Making jalapeno relish

  2. Toast celery seeds.

    Place a medium sauce pan over medium heat. Once hot, add the celery seed, shaking constantly for about 1 minute or until it becomes fragrant.Making jalapeno relish

  3. Add all other ingredients.

    Stir thoroughly until the sugar is dissolved.Making jalapeno relish

  4. Simmer about 10 minutes.

    Bring the mixture to a light simmer and cook for about 10 minutes. Don’t let all of the liquid evaporate, as the spicy relish will thicken up after it cools.Making jalapeno relish

  5. Cool and store in jar.

    Once the mix has thickened slightly, remove it from heat and allow to cool for 20-30 minutes. Add it to a glass jar and store in the refrigerator for 2-3 weeks.Jalapeno relish in jar

The most important step is getting the cooking time right. If your relish turns out a bit too thick and syrupy, simply add a bit more vinegar after removing from the heat.

It is very easy to boil the relish too vigorously, so shoot for a light simmer and watch it closely. The mix should still look somewhat watery when it is finished, as the sugar will thicken it when it is cooled.

Once the relish is cooled enough, give it a taste! If you’re a relish lover, I am sure you’ll be happy with the flavor and you’ll be craving grilled foods.


How Long Does It Last?

I always store this relish in the refrigerator where it will keep for at least 2-3 weeks. The vinegar paired with high sugar content will preserve the jalapeno relish well.

If you want to make a large batch, you could use the waterbath canning method to make the relish shelf stable for months. Just follow safety standards by using new jar lids and boiling for the correct amount of time.

How To Use Spicy Relish

Relish has its obvious uses, but there are many less popular applications for this spicy condiment. Here are a few ideas for how to use your homemade spicy relish.

  • Slather it on a hot dog. The classic use for relish; on a hot dog. The hot meat and the cold relish make the perfect companions. Everyone likes their relish a certain way, but I like it spicy and layered on thick!
  • Add to sandwiches. One could argue that a hot dog is as sandwich, but spicy relish can be used for traditional deli sandwiches, too. Use in place of mayo or mustard.
  • Bring salad to life. If you like pepperoncini in your salads, you may enjoy some spicy relish, too. Zingy, sweet and crunchy relish will only do good things for your greens.
  • Add to a cheese plate. Cheese and crackers have never been so good. Throw a dollop of jalapeno relish on a slice of cheddar and you won’t look back.
  • Spice up tacos. One of my favorite fancy tacos is glazed porkbelly and pickled relish. Try it out on traditional or non-traditional tacos for a surprisingly tasty combo.
  • Add to dip. Next time you make chips and dip, mix in a few spoonfuls of your homemade jalapeno relish. Your guests will be asking for the secret ingredient.

Notes

* If the relish comes out too thick, add a small splash of vinegar and stir. I like a more thin and runny relish (it is a condiment, after all!).

  1. How much cracked pepper do you use if it’s just in a bottle and not the kind with a crank?

  2. 5 stars
    Thanks pepper geek. I really enjoyed your video. I grew tons and tons of jalapenos this summer and I just harvested them. I can’t wait to make the relish!

  3. 4 stars
    I just made it and I’m letting it cool down now. I made 9 cups of chopped jalapeños and I just used more of everything in the receipe. I’m making enough to last at least a couple of months lol. Love this receipe

  4. 5 stars
    Used this on hamburgers and hot dogs, but another place where it really shines is in deviled eggs. This is now a pantry item, meaning that it will always be on hand. Thank you for the recipe!

    I found this recipe while in need of a use for my jalapeno crop. I really, really like it. Easy to make and a really good flavor and heat level. Now I’ve become a Pepper Geek fan, too. Loads of good information on all-things peppers.

  6. 5 stars
    Delicious recipe, I made it last night! I used a bit more sugar and just random peppers from my garden (jalapeno, habanero, serrano, banana, blow). This is definitely something I’ll be making more often next season. And I love your website and newsletter – great tips! Just wish I read the tip to not boil too much because my sugar caused really thick relish LOL Still yummy though

  7. 5 stars
    I substituted Serranos and threw in a couple Black Pearls.
    What a tasty condiment with so many uses!

  8. This is a great relish! The hot weather this year has made the jalapenos mui caliente! I found this trick many years ago. If your relish is too spicy, add a piece of carrot! The carrot will absorb some of the capsaicin. Add a couple to make a milder relish. start with 1/2 of a 1″ piece from the big end.

  9. 5 stars
    I made a batch & love this relish! Problem is the yield is 1 cup and I have lots of jalapenos ready now. If I were to quadruple this recipe would it work to multiply each ingredient by 4 & still taste delish? How about multiplying each ingredient by 8? In other words, what is your guidance for enlarging this recipe? Thanks so much!

  10. 5 stars
    I made this yesterday and gave several small jars to jalapeno lovers and they want more! I did remove all the seeds and membranes so the relish was not hot. Next batch will have a few seeds for a little heat. Maybe I will add a dash of hot sauce? Still thinking….but this is great stuff. Thanks!

  11. 5 stars
    I made this with one addition… 1/2 tsp. Mustard Seed. It is awesome! Thanks for sharing this recipe!
