Why You’ll Love This Salad
This is the salad I make all summer long and bring most often to my parents’ house for Sunday lunch. I never seem to get tired of it, especially with garden-grown cucumbers and tomatoes. The simple lemon dressing makes it taste fresh and bright year-round, even when tomatoes aren’t at their summer best.
It’s perfect with grilled meats, seafood, or a simple weeknight dinner, and it always disappears fast. It’s also naturally gluten-free, dairy-free, vegetarian, and vegan, so it works for a wide range of diets, meals, and gatherings.

Cucumber Tomato Avocado Salad Ingredients
This easy salad is all about fresh ingredients, so use the best tomatoes and avocados you can find. Garden cucumbers and tomatoes make it extra special and give this salad the best summer flavor.
- Tomatoes – Roma tomatoes work well because they are firm and not overly juicy. Cherry or grape tomatoes are also great and hold their shape nicely.
- Cucumber – I love English cucumbers or Persian cucumbers. They are crisp, mild, and don’t need to be peeled.
- Avocados – Choose ripe but firm avocados so they hold their shape when tossed. Avoid overripe avocados, which can get mushy.
- Red onion – Slice it thinly so it blends into the salad. The lemon juice helps mellow the onion as it sits, but if your onion is extra strong, soak the slices in cold water for 10 minutes, then drain well.
- Cilantro – We love the fresh flavor here, but fresh dill is a great substitute.
- Lemon juice and olive oil – This simple dressing is light, fresh, and lets the vegetables shine. You can substitute fresh lime juice.

How to Make Cucumber Tomato Avocado Salad
- Prep the veggies – Chop the tomatoes. If your tomatoes are extra juicy, you can seed them first, but I usually don’t bother. Slice the cucumber and red onion, dice the avocados into bite-sized pieces, and chop the cilantro. Add everything to a large salad bowl.

- Dress the salad – Drizzle with olive oil and fresh lemon juice, then gently toss to combine.

- Season and Serve – Just before serving, add salt and pepper to taste and toss gently again. This helps keep the salad from getting watery too quickly.

Tips for the Best Avocado Salad
- Use ripe but firm avocados – Soft avocados can turn mushy when tossed. Dice them into bite-sized pieces, but don’t cut them too small or they can fall apart.
- Dice the avocado last – This keeps it fresher and helps prevent browning.
- Toss gently – Use a large spoon or spatula to fold the salad instead of stirring hard, which can crush the avocados and make the salad mushy.
- Salt just before serving – Salt pulls moisture from cucumbers and tomatoes, so this keeps the salad crisp and fresh.

Serve With
My husband and I ate this entire batch of cucumber tomato salad with avocado in one sitting, paired with Roasted Potatoes and Grilled Shrimp Skewers. I shoveled most of the salad into my mouth before I remembered the shrimp and potatoes on my plate; mmming and smiling all the way through. We are both smitten. It pairs with just about anything:
- Grilled Steak
- Shrimp Scampi
- Juicy Burgers
- Crispy Chicken Sandwiches
- Grilled Pork Tenderloin
- Instant Pot Ribs

I’m about to go make this right now 😂 instead of making some bs food for this time of night
This is so related, I hope you love this salad, we absolutely love it.
I love your tomato, cucumber, avocado salad. But I’ve run out of cilantro and parsley, but have lots of fresh dill. Can I substitute dill for the cilantro and still have it come out as delicious?
Hi Linda! That would be fine! I hope you love it!
This is such an amazing salad! Very simple to make. I was quite surprised at how the avocado with cucumber combined would taste but I must say they meshed well and were very tasty and delicious!
Thank you for sharing. So glad you’re loving it!
I love this salad. Any ideas for storing it? I want to take it for lunch, however would need to be made the night before.
Hi Amy! It will last about 5-6 hours covered and refrigerated. I would suggest omitting the salt until ready to serve since salt will cause the tomatoes to get juicy and the cucumbers to soften. Cover with plastic wrap directly over the surface of the salad to keep the avocados from discoloring – the lemon juice also helps prevent discoloring
Absolutely awesome recipe!! I make at least once a month. The whole family loves it.
We love this salad so much! I make it at least once a month & more so with fresh veggies in the summer! Thank you for a wonderful recipe!
You’re very welcome.
Absolutely terrific recipe!! I’ve made this at least 10 times. It never gets boring! I do sub the dill for the cilantro just because we’re not big fans of it. I also cheat and add a bit of minced garlic, yum!! Thank you for a perfect recipe!
That’s just awesome! Thank you for sharing your wonderful review, Stephanie!
I use your recipes quite often, always looking for your next recipe postings. Thank You.
Aww, that just makes my day to read. Thank you so much for making my day!
hello thanks for the recipe
id like to tweek the recipe as i dont like dill or cilantro can i use basil? and can i use one avocado and a celery? keep me posted thanks
I have not tested those combinations but feel free to experiment. Any fresh herb can work.
I would try with mint and or curly parsley if you don’t like the herbs suggested. These are commonly used in essentially the same type of salad in middle eastern cuisines. Hope this helps!
We made this salad while enjoying a month in La Cruz, Mexico. It was so easy to put together and really delicious. I’m adding to my recipe collection.
Wow! That sounds like an amazing vacation, Cathy! I bet this tasted so great with local produce!
Hi Natasha…we love this salad and make it often. Question for you…not a big fan of raw onion and wonder if you have an idea for a substitute? Thank you!
Hi Kathy, we prefer it with fresh onion, but chopped green onion would be the closest substitute if you were to try one.
If you don’t like raw onion then try a quick pickled red onion by slicing super thin and salting.. can add vinegar also! They are much less intense in onion flavor when the salt and or vinegar breaks them down a bit 🙂
That’s a great idea, Kelly! I would have never thought of that!
Soaking raw onion in water takes out some of the bite and it doesn’t taste so raw and strong.
This is one of my all time favorites. I only add the lemon juice during assembly, then add Kalamata olives, balsamic vinegar, olive oil, salt & pepper to taste at the table.
Great to hear that this is one of your favorite recipes!
I have tried this recipe a couple times. That’s amazing. The only thing I change is adding more lemon juice
I’m so happy you enjoyed that. Thank you for sharing that with us, Neda!
I make that quite often, just last night as a matter of fact, I never add cilantro (wife request) and sometimes I’ll just use a vinegar oil dressing…but it’s always good no matter what!
Hi Doc John! I’m glad to hear that. Thank you!
I make a salad very similar, just no cucumber or cilantro. The dressing I use is a garlic house dressing sold at Aldi’s. We also have this for breakfast with home style potatoes and eggs.
Absolutely delicious! Can’t say enough about the freshness. This salad is a summer must. We will be making it often! Had it today for the first time with pita bread..YUMMY 🙂
Hi Patricia! That’s wonderful. So glad you found this recipe. Thank you for the feedback.
can (or should) this be made in advance and then chilled? And if so, how much time in advance?
Hi Ana! It will last about 5-6 hours covered and refrigerated. I would suggest omitting the salt until ready to serve since salt will cause the tomatoes to get juicy and the cucumbers to soften.

Love this salad! I add a little bit of honey to balance the tartness of the lemon. My favorite way to eat this is to top it with seasoned chicken breast chunks.
Sounds delicious, Rose! Thank you for the feedback.
I have made a salad similar to this for years. Well, never again, this is so much better! The combo of veggies, especially the avocado, was amazing. Simple, fresh and delicious! Thanks, Natasha 🤩
That’s so great! It sounds like you have a new favorite, Maureen! Thank you for your lovely review!
We are going to be eating this all summer long, it is perfection! The only thing I did different was add a drizzle of a very good balsamic over it and wow! Thank you for a fantastic recipe once again!
You’re welcome, Shawna! So glad you loved the recipe. Thank you for sharing.
