Every year when I bite into the first summer tomato, I wonder what on earth it is I’ve been eating the whole rest of the year. It’s a feeling I can compare to slicing into a perfectly ripe avocado: the delicious sensation of striking ingredient gold. Here to celebrate them both, I have a light and refreshing Cucumber Tomato Avocado Salad.

Cucumber Tomato Avocado Salad with feta and lime dressing

Cucumber tomato salad is part crunchy, part creamy, and entirely what I crave when the days are hot and the nights are sunny and long.

  • Like my favorite Creamy Cucumber Salad, it’s refreshing and crisp, never soggy, and is begging to be topped with fresh herbs.
  • The veggies in this avocado salad—cucumber, red onion, and whatever tomatoes in your garden or at the market look best—are lively and complement each other.
  • The avocado is buttery and luscious (as it is in this other fresh summer Avocado Salad!).
  • The lime dressing is zippy and ties the salad together like a bright citrus bowl.

Make this simple salad tonight for dinner, and serve it with some simply grilled chicken. Tomorrow, toss the leftovers with arugula and chickpeas and enjoy them for a healthy lunch.

However you choose to serve this cucumber avocado tomato salad, just promise me that you won’t wait too long to try it.

How to Make Cucumber Tomato Avocado Salad

Just about everything you need to know about this tasty tomato cucumber avocado feta salad, you can learn from the name. Don’t overthink it.

The magnificent thing about summer recipes like this tomato cucumber salad (and my Asian Cucumber Salad too) is how simple they are.

We’re taking the bounty of the season, dressing it up in a lively citrus vinaigrette, and wondering how on earth life got to be this easy and this good.

The best part? Cucumber and tomato salad is good for you too!

The cucumber tomato avocado salad calories are low, and almost all of the ingredients have wonderful nutritional value.

The Ingredients

  • Tomatoes. Pick ones that are juicy and ripe. When in doubt, I recommend cherry tomatoes or grape tomatoes, since they are almost always sweet (even slightly out of season). Tomatoes are rich in vitamin C.
  • Cucumber. You can put cucumber and tomatoes together, and it’s delish! I like an English cucumber here because you don’t need to peel it. Crisp cucumber is delicious, keto-approved, has a high water content, and is rich in antioxidants.


If you have a regular cucumber, peel it first (use a vegetable peeler like this one or better yet, a Y-shaped peeler like this one), split it down the center, and scoop out any large seeds.

  • Red Onion. My favorite raw red onion tip: thinly slice the onion, then soak it in water for a few minutes before adding it to the salad. This preserves its flavor while mitigating the harsh, lingering aftertaste.
  • Avocado. The creamy avocado texture is a lovely contrast to the crispness of the cucumber. Plus, tomatoes and avocado together are delightful. Since avocado is rich in fiber and healthy fats, it makes the salad more filling and satisfying too.
  • Feta Cheese. You can omit it in a pinch, but the recipe is truly delicious as a tomato avocado feta salad. The feta adds more creaminess and a salty element.
  • Fresh Herbs. I like cilantro or dill, but any tender fresh herbs will work here. A tomato cucumber avocado basil salad is next on my list.
  • The Dressing. The avocado cucumber salad dressing is a quick whisk of lime juice, extra-virgin olive oil, honey, salt, black pepper, and garlic. It takes moments, brings the ingredients together, and goes smashingly with avocado.

The Directions

A bowl of red onion slices in water
  1. Soak the red onions in water, then drain.

Recipe Variations

  • Mexican Avocado Salad. Customize this salad with some delicious add-ins like jalapeno or corn and use cilantro as the fresh herb (take inspiration from my Grilled Corn Salad). Try swapping the feta for queso fresco.
  • Chicken Cucumber Tomato Avocado Salad. Add protein to take this from side dish to full meal. Shredded chicken is a simple and delicious addition.


Cut this recipe time even further by swapping in precooked chicken or leftover chicken made with one of these easy methods (or use store-bought rotisserie chicken):

  • Go Green. Mix the leftovers with arugula, kale, or spinach for a green salad with avocado. I’d suggest making a little extra of the dressing to make sure you have enough to properly coat it.
  • Avocado Salad without Tomatoes. Try this Watermelon Feta Salad with Mint Avocado and Lime for a delicious fruit and avocado salad without tomatoes.
  • Mango Avocado Salad Recipe. For a tropical twist, add 1 cup chopped mango to this salad.

Storage Tips

  • To Store. Store leftovers in the refrigerator for up to 1 day. The avocado will brown slightly, and the vegetables will become more liquidy, but the salad will still taste delicious. You can also perk the leftovers back up with a squirt of extra lime juice and sprinkle of salt.

Leftover Ideas

  • Add diced Grilled Chicken Tenders or flaked Pan Seared Salmon to your leftovers for a boost of protein.
  • Serve leftovers over a bed of lettuce for a green salad.
  • You could also add the leftovers to a serving of cooked, cooled whole wheat pasta for a pasta salad version.

What to Serve with Cucumber Tomato Avocado Salad

  • Citrus Juicer. Makes light work of juicing lemons and limes.
  • Non-Slip Cutting Board. This one won’t slip out from under you while you’re chopping the ingredients for this creamy avocado tomato cucumber salad.
  • Mixing Bowls. You can mix and serve your salad in these beautiful bowls.

I hope this healthy, top-rated cucumber tomato avocado salad adds a note of lightness and brightness to your week!

Frequently Asked Questions

Can I Prep the Salad Ahead of Time?

Prep the salad up to 6 hours in advance, and give it a big stir just before serving. I don’t recommend putting avocado in salad the night before, as it will turn brown. To deter the avocado from turning brown, I like to add it immediately before serving.

Can I Use Lemon Juice instead of Lime Juice?

While we enjoy this salad dressing with lime juice, other readers have reported success with swapping in lemon juice instead.

What if I’m not a Fan of Cilantro?

If you don’t enjoy the taste of cilantro, you can simply swap an herb you do enjoy. I think basil, dill, or parsley would be tasty.

Is this Salad Dietary Friendly?

Yes, this salad is gluten free as written. If you need to make this salad keto friendly, you could swap the honey for a different, approved liquid sweetener. To make vegan, omit the feta.

Can I Use a Different Dressing?

While we love the cucumber tomato avocado salad dressing in this recipe, you could swap it out if you prefer. I think a tomato avocado salad balsamic would be tasty (swap in a balsamic vinaigrette).
