How to Make Tomato Cucumber Salad
What you need
- 2 cups ripe cherry tomatoes or chopped garden tomatoes
- 1 large cucumber, diced
- 1 ripe avocado, diced
- 2 tablespoons red onion or green onion, finely sliced
- 2 tablespoons fresh lemon or lime juice
- 2 tablespoons extra virgin olive oil
- 1 small garlic clove, grated or minced
- Salt and freshly ground black pepper, to taste
- Handful of fresh herbs like parsley, basil, or cilantro
Easy steps
Chop the tomatoes and cucumber into bite size pieces. Try to keep them similar in size so every bite tastes balanced. Add them to a big bowl with the sliced onion.
Whisk the lemon juice, olive oil, and garlic in a small cup. Season with a good pinch of salt and pepper. Pour over the bowl and toss gently to coat.
Dice the avocado last and fold it in with a light hand. You want those pieces to stay intact for that creamy bite. Add chopped herbs and taste again. If it needs a lift, add another splash of lemon and a pinch of salt.
Pro tip: Salt the tomatoes and cucumbers first and let them sit for 5 minutes. It draws out a little moisture and amps up the flavor.

Tips for Prepping Ingredients
Buy and prep like a pro
Tomatoes: Use ripe but firm tomatoes so they do not turn mushy once tossed. If they are extra juicy, scoop out some seeds or let the chopped pieces sit with a little salt for a few minutes, then drain.
Cucumbers: If you are using English cucumbers, you can leave the skin on for color and crunch. For regular cucumbers, peel if the skin tastes bitter. If seeds are large, slice the cucumber lengthwise and scrape the seeds out with a spoon.
Avocados: Pick avocados that give slightly when pressed. Dice right before serving to keep them bright. If you need to prep ahead, toss the avocado pieces with lemon or lime juice to slow browning.
Onion: Red onion brings a little bite. If it tastes too sharp, soak slices in water for 5 minutes, then drain and pat dry.
Herbs: Fresh herbs make everything pop. Basil adds fragrance, parsley adds freshness, and cilantro leans in a bright, citrusy direction.
Flavor keys: Season generously, add enough acid, and balance with just enough oil to coat. If the salad tastes flat, it usually needs another squeeze of lemon and a pinch of salt.

Make It Your Own
There is no one right path here. The base is simple and flexible, which is why I make it all the time. Try one of these twists and see what sticks.
Greek style: Add crumbled feta, olives, and a sprinkle of dried oregano. Swap lemon for red wine vinegar.
Southwest style: Toss in black beans, corn, and a touch of cumin. Finish with cilantro and lime.
Mediterranean picnic: Add chickpeas, roasted red peppers, and a spoon of capers for briny depth.
Spicy kick: Finely slice a jalapeño or add red pepper flakes. A spicy note makes the creamy avocado pop.
Extra crunchy: Stir in toasted pumpkin seeds or pine nuts just before serving so they stay crisp.
More creamy: Whisk a teaspoon of Dijon into the dressing for a silky finish without heaviness.

Common Questions
How long does this salad keep?
It is best the day you make it. If you want leftovers, store the salad without avocado and add it fresh before eating. It will hold in the fridge for up to 2 days.
Can I make the dressing ahead?
Yes. Mix lemon juice, olive oil, garlic, salt, and pepper and keep it in a jar for up to a week. Shake before using.
What tomatoes are best?
Use ripe but firm tomatoes. Cherry tomatoes are an easy choice since they stay juicy and sweet without turning watery.
Can I add protein directly to the salad?
Absolutely. Grilled chicken, shrimp, or chickpeas fold in nicely. Keep pieces small so the salad still feels light.
How do I keep avocado from browning?
Toss diced avocado with lemon or lime juice. If storing, press plastic wrap directly onto the surface of the salad to limit air exposure.
