This is a five-ingredient tomato salad dressed with olive oil, red wine vinegar, basil, and oregano โ no cooking required. It takes ten minutes of actual work, costs almost nothing, and the marinating time does most of the heavy lifting for you.
The short version of why this works
Two things matter here. First, grinding the dried herbs before they go in โ whether in a mortar or between your palms โ breaks the cell walls and releases the volatile oils that would otherwise stay locked inside. Whole dried oregano sitting in a bowl of tomatoes barely contributes flavor; crushed oregano does. Second, the one-hour rest isnโt optional. Salt draws moisture out of the tomatoes and onion, which combines with the olive oil and vinegar into a light, savory liquid that becomes the dressing. Skip the rest and you have underdressed vegetables; honor it and the whole bowl ties together.
Troubleshooting
- The salad tastes flat even after marinating. Tomatoes vary a lot in acidity and sweetness. Taste after the rest and add a small extra splash of red wine vinegar โ about a teaspoon โ if it needs brightness, or a pinch of sugar if the tomatoes are underripe and sharp.
- The onion is too harsh. Raw red onion can be aggressive. Soak the chopped onion in cold water for 10 minutes before adding it. This pulls out some of the sulfur compounds without losing the crunch or color.
- The tomatoes are releasing too much water and diluting everything. This usually means the tomatoes were refrigerated. Use room-temperature tomatoes โ cold storage breaks down their cell walls and causes excessive weeping once cut.
- The olive oil isnโt incorporating with the vinegar. Oil and vinegar separate naturally. Give the bowl a good stir right before serving rather than expecting them to stay emulsified. The liquid at the bottom is still worth using โ itโs what you want for bread dipping.
- The basil turned dark and limp. If youโre using fresh basil instead of dried, add it in the last 10โ15 minutes of the rest period, not at the start. Acid and salt wilt fresh herbs quickly.
Ingredient notes
- Roma tomatoes: Good default choice because theyโre meaty and low in water. Any ripe tomato works โ beefsteak, vine, or even a mix of cherry tomatoes halved. The key is ripe, not refrigerated.
- Red wine vinegar: White wine vinegar or sherry vinegar are the closest swaps and wonโt change the flavor much. Apple cider vinegar works in a pinch but adds a slightly fruity note. Plain white distilled vinegar is too sharp โ avoid it here.
- Olive oil: This is the bulk of the dressing, so use the best one you have on hand. A neutral oil like avocado oil can substitute if needed, though the flavor will be milder.
- Dried oregano: Standard pantry dried oregano is exactly right. Italian seasoning blend can stand in if thatโs what you have โ just use the same amount.
Make-ahead notes
This salad is actually better after an hour than right away, and it holds well for up to 24 hours in the refrigerator โ the flavors keep deepening. Beyond that, the tomatoes get progressively softer and the liquid becomes watery rather than savory. Store it covered in the bowl you mixed it in; thereโs no need to separate components. Pull it out of the fridge 20โ30 minutes before serving so the olive oil, which solidifies slightly when cold, returns to liquid. Dress it at the table if youโre serving guests โ a pre-dressed salad thatโs been sitting out for more than two hours starts to look tired. The accumulated liquid at the bottom is worth keeping; serve it alongside with bread.

Frequently asked questions
Can I use fresh oregano instead of dried?
Yes, but use about three times as much โ roughly one tablespoon of fresh chopped oregano for every teaspoon of dried. Fresh oregano is milder and has more moisture, so the flavor wonโt be quite as concentrated, but it works well.
Do I have to use Roma tomatoes specifically?
No โ any ripe tomato you have will do. Roma tomatoes are a practical default because theyโre widely available and have less water content, which keeps the dressing from getting too diluted. Beefsteak, vine-ripened, or a handful of cherry tomatoes all work fine.
Can I add other vegetables to stretch it further?
Yes, and itโs a good way to use up whatโs in the fridge. Thinly sliced cucumber, chopped bell pepper, or halved kalamata olives all fit the flavor profile without changing the dressing. Add them at the same time as the tomatoes so they marinate together.
What can I serve this with to make it a full meal?
It pairs well alongside grilled or pan-cooked chicken or fish, which the recipe card notes. The accumulated liquid at the bottom is also excellent for soaking into crusty bread, making it satisfying enough as a light meal on its own with a good loaf.
