ingredients
(Here's a tip: Check out the full list of ingredients and measurements in the recipe card below.)
- Cherry tomatoes
- Red onions
- Cucumbers
- White vinegar or apple cider vinegar
- Water
- Sugar
- Salt
- Garlic cloves (optional)
- Whole peppercorns (optional)
- Fresh herbs like dill or parsley (optional)
directions
- I slice the cucumbers and red onions thinly, and I leave the cherry tomatoes whole or cut them in half if they’re large.
- I pack the vegetables tightly into clean jars or containers.
- In a saucepan, I combine the vinegar, water, sugar, and salt. I bring it to a boil, then remove it from heat.
- If I’m using garlic, peppercorns, or herbs, I add them to the jars with the vegetables.
- I carefully pour the hot brine over the vegetables until they’re fully submerged.
- I let them cool to room temperature before sealing and refrigerating.
- I wait at least 4 hours before eating, but they taste even better after 24 hours.
Servings and timing
This recipe makes about 2-3 pint-sized jars, which serves around 6-8 people as a side or topping. Prep time is 10 minutes, and the brine takes just 5 minutes to make. I recommend chilling for at least 4 hours before serving.
Variations
Sometimes I add sliced jalapeños or red pepper flakes for heat. Swapping white vinegar for rice vinegar gives it a milder taste. I’ve also tossed in carrot slices or radishes for extra crunch and color. For a more herbaceous flavor, I use fresh thyme or rosemary.
storage/reheating
I store the pickled vegetables in sealed jars in the fridge for up to 2 weeks. There’s no need to reheat them—just scoop out what I need and serve cold or at room temperature.
FAQs
Do I have to use a specific type of vinegar?
I usually use white vinegar or apple cider vinegar, but rice vinegar or white wine vinegar also works well.
Can I reuse the pickling brine?
Yes, I sometimes reuse it once for a second batch, but the flavor will be slightly less intense.
How do I keep the vegetables crisp?
I slice the cucumbers thicker and don’t overcook the brine. Cooling the veggies quickly in the fridge helps too.
Are these safe for long-term storage?
No, since they aren’t canned, I keep them refrigerated and use them within two weeks.
Can I pickle other vegetables with this brine?
Absolutely. I’ve used it for radishes, carrots, green beans, and even cauliflower.
Conclusion
These pickled cherry tomatoes, red onions, and cucumbers are a simple and delicious way to add brightness and crunch to my meals. They’re easy to make, endlessly adaptable, and always add that perfect tangy kick. I love having a jar or two on hand for whenever I need a flavor boost.
