Pickled Pepper Relish

I'd describe this Pickled Pepper and Onion Relish as a burst of color and flavor in a jar. The first time I encountered something similar was at a small-town fair where a vendor was selling homemade preserves. I bought a jar of pepper relish on a whim, and after tasting it, I knew I had to learn how to make it myself. This recipe captures that same bright, tangy-sweet flavor profile that made me fall in love with it in the first place. The process is surprisingly straightforward – you dice up colorful bell peppers and onions, simmer them in a sweet-tangy vinegar brine with aromatic spices like mustard and celery seeds, and then let the mixture cool to allow all those flavors to meld together. What makes this relish special is the balance between the natural sweetness of the peppers, the sharpness of the onions, and the acidic punch of the vinegar. The spices add depth and complexity, while the red pepper flakes provide just a whisper of heat. The texture is wonderfully crunchy, and the colors remain vibrant even after pickling. It's one of those recipes that looks impressive but is actually quite forgiving and easy to make, even for beginners.

It's become one of my signature recipes, and making it has become a yearly tradition I truly look forward to.

What You Need From Your Kitchen

• Bell peppers: Wash, seed, and dice into small uniform pieces
• Onions: Peel and dice into small cubes matching the pepper size
• White vinegar: Use as the acidic base for the pickling brine
• Granulated sugar: Dissolve in the vinegar to create the sweet-tangy balance
• Mustard seeds: Add to the brine for aromatic depth and traditional pickle flavor
• Celery seeds: Include for earthy, herbaceous notes in the relish

Let's Make These Together

Prepare Your Vegetables

Start by washing all your bell peppers and onions under cool running water. Pat them dry with a clean towel. Remove the stems, seeds, and white membranes from the peppers, then dice both the peppers and onions into uniform pieces about 1/4-inch in size. Consistent sizing ensures even pickling and a professional-looking final product.

Create the Pickling Brine

In your large saucepan, combine the white vinegar, sugar, mustard seeds, celery seeds, red pepper flakes, and salt. Place the pan over medium-high heat and stir the mixture regularly until all the sugar and salt have completely dissolved into the vinegar. Continue heating until the brine reaches a gentle boil, filling your kitchen with that distinctive tangy aroma.

Simmer the Vegetables

Once your brine is boiling, carefully add all the diced peppers and onions to the pot. Stir everything together thoroughly to coat all the vegetables in the brine. Reduce your heat to medium and let the mixture simmer for 10-15 minutes, stirring occasionally. You want the vegetables to soften slightly while still maintaining a pleasant crunch.

Cool and Jar

When the vegetables have reached your desired texture, remove the saucepan from the heat and let everything cool to room temperature. This cooling period allows the vegetables to continue absorbing the brine flavors. Once cooled, carefully transfer the relish and all the brine to your prepared glass jars, seal them tightly, and place them in the refrigerator.

Let Flavors Develop

Although you can eat the relish right away, the magic really happens after the first 24 hours of refrigeration. During this time, the vegetables fully absorb the pickling brine, and all the spice flavors meld together beautifully. The result is a perfectly balanced, crunchy, and flavorful relish that will elevate any meal you pair it with.

The colors were so vibrant that I couldn't stop taking photos before jarring it up. What started as a way to use excess produce quickly became a staple in my kitchen.
