Why You’ll Love This Recipe
I love this recipe because it’s fast, easy, and packed with flavor. The sweet and sour brine gives the vegetables a perfect balance of brightness and depth. I can prep it ahead of time, and it just gets better the longer it sits in the fridge. It's also a fantastic way for me to use up extra vegetables and have a healthy side or topping ready to go anytime.
Ingredients
(Here's a tip: Check out the full list of ingredients and measurements in the recipe card below.)
- Cherry tomatoes
- Red onion, thinly sliced
- Cucumber, thinly sliced
- White vinegar
- Water
- Sugar
- Salt
- Dried oregano
- Red pepper flakes (optional)
- Fresh dill, chopped
Directions
- I start by washing and drying the cherry tomatoes, onion, and cucumber. Then I slice the onion and cucumber thinly.
- In a saucepan, I combine the white vinegar, water, sugar, salt, oregano, and red pepper flakes. I bring this to a boil over medium heat and stir until the sugar and salt dissolve.
- I place the vegetables into a clean glass jar or container.
- I pour the hot pickling brine over the vegetables until they’re fully submerged.
- I add the chopped dill, seal the jar, and let it cool before refrigerating.
- I let the pickles chill in the fridge for at least 2 hours before eating, though I prefer to wait overnight for even more flavor.
Servings and timing
This recipe makes about 4 servings. It takes me around 10 minutes to prepare and at least 2 hours of chill time in the fridge before it's ready. For the best flavor, I often make it the night before.
Variations
- I sometimes add sliced carrots or bell peppers for more color and crunch.
- Swapping white vinegar for apple cider vinegar gives a slightly sweeter and fruitier brine.
- I occasionally toss in a few crushed garlic cloves or mustard seeds to deepen the flavor.
Storage/Reheating
I store the pickled vegetables in an airtight container or jar in the fridge. They stay fresh and flavorful for up to 2 weeks. I don’t reheat them—these are best served cold or at room temperature.
