This pickled cucumber salad is one of those recipes you’ll make once and then keep making every summer. Crisp cucumbers, onions, and bell peppers in a sweet tangy brine — it gets better the longer it sits, and it goes fast. Try our Million Dollar Cucumber Salad next.
Why You’ll Love It
- Crisp for weeks — pickling cucumbers hold their crunch long after the jar’s been opened
- Flavor builds over time — it’s genuinely better on day four than day one
- Sweet, tangy, and just a little complex — the celery and mustard seed do more than you’d expect
- No canning skills needed — it lives in the fridge, not on a shelf
- Endlessly snackable — fork straight from the jar counts as a snack and I won’t apologize for that
A Few Notes on the Ingredients
Don’t use the long English cucumbers. I know they’re easier to find and they look nice and they’re fine for a lot of things but they’re too watery for this and they’ll turn soft on you within a few days. You want the small pickling cucumbers — bumpy skin, firm all the way through. Don’t peel them either. The skin gives the whole thing a little bite that you’d miss.
Bell peppers: I use green and red because I like the color contrast and because green adds a faint bitterness that keeps the brine from tipping too sweet. Orange or yellow would probably work. I just haven’t tried it. If you like this, you'll love our That Salad Grandma Always Made: Marinated Cucumber, Onion & Tomato.
The celery seed is non-negotiable. I know it sounds like a minor thing and it is not a minor thing. Same with the mustard seed. They both end up suspended in the brine and they give it this depth that’s hard to name but obvious when it’s missing — I made a batch once without the celery seed because I’d run out and thought I’d get away with it. You don’t get away with it.

Ingredients
- 7 large pickling cucumbers, unpeeled and sliced thin — roughly 7 cups (I aim for about an eighth of an inch, sometimes a little thicker)
- 2 medium onions, sliced thin — about 1 cup
- 1 cup sliced bell peppers, green and red
- 1 tablespoon salt
- 1 cup white vinegar
- 2 cups sugar
- 1 teaspoon celery seed
- 1 teaspoon mustard seed
Makes 2 quarts — two standard mason jars.
How to Make It
Slice the cucumbers, onions, and peppers and toss them together in a large bowl with the salt. Mix it around and then leave it alone for an hour. The salt pulls moisture out of everything, which is exactly what you want. I’ve let it go two hours by accident and it was fine — if anything, a little better.
While you’re waiting, make the brine. Combine the vinegar, sugar, celery seed, and mustard seed in a small pot and bring it to a boil over medium heat. Stir it as you go so the sugar dissolves cleanly. The moment it hits a full boil, pull it off the heat and let it cool completely — this takes about an hour, or you can set the pot somewhere cold to speed things up. Don’t pour it over the vegetables while it’s still warm. The cucumbers need the shock of cold brine to stay crisp.
Once the brine is cool, pour it over the vegetable mixture. Stir everything together, pack it into mason jars — vegetables first, then brine — and refrigerate. For another easy option, see our Shoepeg Salad An easy summer salad that always hits the spot.
Overnight is the minimum before you eat it. Two days is better. I know that’s hard to hear but I’m telling you anyway.
Variations
Red pepper flakes will give you a sweet heat version that’s genuinely good if you like that combination — about a quarter teaspoon per jar is enough. More than that and the heat starts to crowd everything else out.
Apple cider vinegar works as a substitute but the flavor gets murkier, less sharp. White vinegar keeps things clean and bright and I always come back to it.
The sugar is high — two cups — and yes, you can cut it back. A cup and a half works. A cup makes it noticeably more tart and less like itself. It’s still good, just a different thing. You might also like our Sour Cream & Dill Cucumbers.
Storage
Sealed mason jars in the refrigerator. Up to two months, technically. I’ve never verified this personally because the jars are empty well before that point, but that’s the number I’ve always heard and I have no reason to doubt it.
