This marinated tomato salad is delicious year-round, but it’s especially wonderful in the warmer months. Made with juicy cherry tomatoes, tangy red wine vinegar, and lemony oregano, this salad is refreshing and can be made quickly, thanks to its limited ingredients.
This salad frequently appeared during the summer when I was a kid, and I think I love it as much for the nostalgia as I do the taste. My mother whipped it up quickly as my dad stood outside—hovering over the barbecue and under the blazing sun—grilling up chicken thighs, flank steaks, and burgers.
For years, this was one of those “recipes” I always eye-balled when adding ingredients because it was never really a recipe until I decided to include it on this blog. I had to figure out the exact measurements to publish it as one, but I didn’t need to strain too many brain cells because the few ingredients made it a cinch to put together. It will be a cinch for you, too.
Red onion, olive oil, and a dash of salt and pepper round out this simple marinated tomato salad. It’s very forgiving, and you can taste as you go and alter the measurements to your liking.
Why You’ll Love This Marinated Tomato Salad
- It’s one of the quickest salads you can make: It comes together in 15 minutes or less.
- It’s versatile: You can easily change it up, and it makes a nice side for just about any main protein.
- It tastes good leftover: The tomatoes hold up well to the dressing, unlike lettuce-based salads.
Key Ingredients
- Cherry Tomatoes: These firm yet sweet tomatoes are best, but you can also use grape tomatoes.
- Dried Oregano: This is a key ingredient because it gives this salad its distinctive flavor. Do not use fresh oregano.
- Red Wine Vinegar: This is an essential ingredient here and is preferable to other vinegar.

How to Make Marinated Tomato Salad
- Mix the salad: Place all ingredients in a bowl (cherry tomatoes, red onion, dried oregano, salt, pepper, red wine vinegar, and extra virgin olive oil) and stir together well. Adjust for seasoning, if needed.
Pro Tips
- Add the vinegar before the olive oil: This will allow the vinegar to penetrate the tomatoes, whereas adding the oil first could create an “oil slick” and make it harder for the vinegar to cling to anything.
- Make the salad ahead of time: Although you can eat this cherry tomato salad right after assembling it, marinating it first will enhance the flavors and pickle the red onions, making them sweeter. It only needs to sit in the fridge for one to two hours.
- Transfer the salad to another bowl before serving: As the salad marinates, juices drain from the tomatoes and create more liquid at the bottom of the bowl. If you’re serving this to company and want it to look pretty, use a slotted spoon to transfer the salad to another bowl and discard the leftover liquid.
Suggestions for Variations and Substitutions
-You can use thinly sliced shallot in place of the red onion.
-Add some minced fresh parsley for more color and freshness.
Recipe FAQs
Firmer tomatoes work best for a variety of salads, particularly those with acidic dressings, which tend to break down certain ingredients upon contact. Cherry and grape tomatoes are good choices because they’re firm and can be left whole or (preferably) just sliced in half.
