Ingredients to Make Cucumber, Tomato, Avocado Salad

  • Cucumbers
  • Avocado
  • Grape or cherry tomatoes
  • Green onions
  • Lime juice
  • Cilantro
  • Avocado oil
  • Salt

What Kind of Cucumbers to use in Cucumber, Tomato, Avocado Salad

While you certainly can use the regular waxy cucumbers from the grocery store, you’ll need to peel them and remove the seeds with a spoon.

Or, use English cucumbers. These are long, skinny cucumbers with very few seeds and an edible peel. These’ll add more fiber and color to this lovely dish!

How to Make This Keto Cucumber Salad

  1. Dice the cucumber, slice the tomatoes in half, and chop the green onions and cilantro.
  2. Make the dressing by mixing the avocado oil with finely chopped cilantro, lime juice, and salt.
  3. At the last minute dice the avocado.
  4. Toss everything together and serve!

Chef Jenn’s Tips

This is a lovely, colorful and light salad that’s also packed with nutrition. Here are some tips for making sure your salad turns out perfectly!

  • Use English cucumbers – you can leave the skin on these long and nearly seedless cucumbers which adds more fiber and color to this salad.
  • Slicing the cherry or grape tomatoes helps add to the flavor of the vinaigrette.
  • Don’t skip the lime juice – not only is a bit of acidity needed in this salad, but the lime juice will help keep the avocado from oxidizing.
  • While this salad can be prepped ahead of time, don’t add the avocado until just before serving so it keeps green and fresh longer.

What To Serve With This Keto Avocado Salad

This Cucumber, Tomato, Avocado Salad is an amazing lunch or meal on its own, but it pairs so nicely with other dishes including:

How To Store This Keto Salad Recipe

The salad, minus the avocado, will keep in the fridge for a day or two, but once you’ve added the avocado, you’ve got maybe two hours before it starts to oxidize.

This Cucumber, Tomato, Avocado Salad is best eaten fresh once the avocado has been added.

Are avocados keto?

Yes! Not only are avocados a super source of nutrition, they’re low in carbs which makes them the perfect fruit.

How do you store this avocado salad?

If making it ahead, I’d package the dressing separate from the chopped tomato and cucumbers. They’ll keep in the fridge for a day or two. Add the avocado just before eating.

I don’t like cilantro, what else can I use?

Parsley! While the flavor won’t be quite the same, parsley will give it a lovely herbaceous flavor.

A Note on Nutritional Information

Nutritional information for this recipe is provided as a courtesy and is calculated based on available online ingredient information. It is only an approximate value. The accuracy of the nutritional information for any recipe on this site cannot be guaranteed. Erythritol carbs (sugar substitutes) are not included in the carbohydrate counts as they have been shown not to impact blood sugar, and they have zero calories and zero carbs. Net carbs are the total carbs minus fiber.

Salads are a delicious way to add fiber and nutrition to your meal. But there are other tasty keto dishes to enjoy, like these classic keto breakfast egg bites or this deli corned beef hash. For lunch, nothing is better than a big bowl of soup, and for dinners, this meaty sausage dish is a winner. Love casseroles? This Southern casserole is a big hit in my house!
