Marinated Cucumbers, Onions, and Tomatoes 🥒🧅🍅

There’s something so refreshing about a bowl of marinated vegetables—crisp, tangy, and bursting with summer flavors. This recipe for marinated cucumbers, onions, and tomatoes is one of those dishes that disappears fast at picnics and potlucks. It’s simple, vibrant, and utterly crave-worthy. Let’s gather our ingredients and get started!

Ingredients You’ll Need

• 2 large cucumbers – I prefer English cucumbers for their thin skin and fewer seeds, but any fresh cucumber will do. Just slice them into half-moons for that perfect bite.
• 1 medium red onion – Thinly sliced into rings for a mild, sweet crunch. If raw onions are too strong for you, a quick soak in cold water mellows them out beautifully.
• 2 cups cherry tomatoes – Halved for juicy bursts of sweetness. Heirloom tomatoes would be divine here if you have them!
• ½ cup apple cider vinegar – The tangy backbone of our marinade. White vinegar works too, but apple cider adds a lovely fruity note.
• ¼ cup olive oil – For richness and to help carry all those delicious flavors.
• 2 tablespoons honey – Just enough sweetness to balance the acidity. Maple syrup or sugar works in a pinch.
• 1 teaspoon salt – Enhances every flavor in the bowl.
• ½ teaspoon black pepper – Freshly cracked, if possible, for a little warmth.
• 1 tablespoon fresh dill – Chopped finely for that herby brightness. If you don’t have fresh, a teaspoon of dried dill will do.
• 1 clove garlic, minced – Because a little garlic makes everything better.

Let’s Make It Step by Step

1. Prep the veggies. Wash and slice your cucumbers into half-moons, about ¼-inch thick. Slice the red onion into thin rings—don’t worry if they separate naturally. Halve the cherry tomatoes and set everything aside in a large mixing bowl.
2. Whisk the marinade. In a small bowl, combine the apple cider vinegar, olive oil, honey, salt, pepper, minced garlic, and fresh dill. Whisk until the honey dissolves and everything is well blended. Taste and adjust the seasoning if needed—sometimes I add an extra pinch of salt or a drizzle of honey.
3. Combine and marinate. Pour the dressing over the vegetables and gently toss everything together, making sure every piece gets coated. I like to use my hands for this step—it feels more intimate, like I’m really giving the veggies some love.
4. Let it rest. Cover the bowl and refrigerate for at least 30 minutes, though an hour is even better. The longer it sits, the more the flavors meld and the onions soften just enough to lose their sharp edge.

While we wait for the magic to happen, I always sneak a bite or two—just to “check the seasoning,” of course. The crisp cucumbers soak up the tangy marinade, the tomatoes burst with sweetness, and the onions add just the right amount of zing. It’s pure summer in a bowl.

FAQs

Can I make this ahead of time?

Absolutely! In fact, letting the veggies marinate for at least an hour (or even overnight) deepens the flavors. Just be sure to give it a good stir before serving.

What’s the best way to store leftovers?

Keep any leftovers in an airtight container in the fridge for up to 2–3 days. The veggies will soften slightly but still taste delicious.

Can I add other vegetables?

Of course! Bell peppers, radishes, or even avocado (added just before serving) would make great additions. Get creative with what’s in season!

Is there a substitute for vinegar?

If you don’t have apple cider vinegar, white wine vinegar or even lemon juice will work beautifully for a bright, acidic touch.

Can I make this sweeter or less sweet?

Definitely! Adjust the sugar or honey to your taste—start with less and add more if needed. You can even skip it entirely for a more savory version.
