Creamy Cucumber Avocado Salad
A crisp, cool salad that leans on ripe avocado to create its own creamy dressing. It comes together in about 10 minutes with no cooking at all, which makes it a workhorse side for busy nights.

The crunch of cucumber next to buttery avocado feels like summer on a plate, but the lime and cilantro keep it sharp enough to serve alongside just about any main dish.
What Makes This Salad So Good
The dressing is built right into the bowl. As you toss, the soft avocado coats the cucumber, so you get a creamy texture without mayo or sour cream.
That means fewer dishes and a cleaner taste. The lime cuts through the richness just enough, and the cilantro adds a fresh grassy note that ties it all together.
Ingredients

- 2 medium cucumbers: any thin-skinned variety like English or Persian works best, no peeling needed
- 2 ripe avocados: should yield slightly when pressed but still hold their shape when cubed
- 1/2 small red onion: thinly sliced, use a mandoline if you have one for paper-thin rings
- 1/3 cup chopped fresh cilantro: packed lightly, stems included
- 3 tbsp fresh lime juice: about 1 1/2 limes, bottled works in a pinch but fresh is brighter
- 2 tbsp olive oil: use something you like the taste of, it stays fairly present
- 1/2 tsp fine sea salt: plus more to taste
- 1/4 tsp black pepper: freshly ground gives a little heat behind the lime
Variations / Substitutions
- Swap the herb: substitute the cilantro with flat-leaf parsley, mint, or a mix. Dill is lovely here too.
- Change the onion: shallot or thinly sliced green onion will give a milder bite than red onion.
- Add heat: fold in one minced jalapeño or a pinch of red pepper flakes with the dressing.
- Lemon instead of lime: lemon juice works and tastes slightly mellower, adjust salt accordingly.
- Make it creamy: stir in 2 tbsp of plain yogurt or sour cream along with the lime juice for a richer finish.

How to Make Creamy Cucumber Avocado Salad
Step 1: Whisk the Lime Dressing

In a large bowl, whisk together the 3 tbsp lime juice, 2 tbsp olive oil, 1/2 tsp salt, and the 1/4 tsp pepper. Whisk for about 20 seconds until the mixture looks slightly cloudy and the salt dissolves.
It will smell sharp and bright, which is exactly what you want to wake up the vegetables.
Step 2: Toss the Cucumber and Onion

Add the sliced cucumber and red onion to the bowl with the dressing. With clean hands or two spoons, toss until every piece is coated and the onions separate into rings.
The cucumber will glisten and start to release a little liquid, and the onion will soften just slightly from the acid. Let it sit while you cut the avocado, no more than a couple of minutes.
Step 3: Fold in the Avocado and Cilantro, Then Serve

Cube the avocado right into the bowl if you like, or on a cutting board first. Sprinkle the 1/3 cup cilantro over everything, then use a spatula to fold gently. You want the avocado pieces to stay mostly intact but smear the dressing just enough to make the whole bowl look creamy.
Spoon the salad onto a wide plate or shallow bowl so the color comes through, and serve right away while the avocado is firm and bright green.
Tips for Foolproof Cucumber Avocado Salad
- Salt the cucumber first if you have time. Lay the slices in a colander, sprinkle with a little extra salt, and let them drain for 10 minutes. Pat dry before dressing. This keeps the salad from getting watery.
- Pick avocados that are just barely ripe. Too soft and they turn to mush when you fold. You want them to hold cubes.
- Slice the onion thin. Thick rings dominate the bite. Use a mandoline or a sharp knife and aim for almost translucent rounds.
- Serve within 30 minutes. Avocado will start to brown after that, even with lime juice, so mix this right before eating.

Keeping Leftovers Fresh
The avocado will oxidize in the fridge, so this salad really tastes best the day it’s made. If you need to store leftovers, spoon them into an airtight container, press plastic wrap directly onto the surface to push out air, and refrigerate for up to 1 day. The color will dull but the flavor stays good.
Reheating doesn’t apply here, but you can serve it cold straight from the fridge. Give it a quick toss to redistribute the dressing.
What Goes Well With Creamy Cucumber Avocado Salad
This salad cools down grilled mains like jerk chicken or carne asada, where the lime and cilantro echo the seasonings. It also works next to simple pan-seared fish, especially salmon, because the richness of the fish and avocado play off each other without fighting. For a vegetarian meal, pile it onto black bean tacos or serve it with warm tortillas and a fried egg.
Frequently Asked Questions
Can I use white onion instead of red?
Yes, though white onion has a sharper bite. Soak the slices in ice water for 5 minutes, then drain well before adding to the salad.
My salad turned out watery, what went wrong?
Cucumber releases a lot of liquid. Either salt the slices ahead of time as described in the tips, or use Persian cucumbers which have thinner skins and less water.
Is there a way to prep this ahead for a party?
You can whisk the dressing and slice the cucumber and onion up to 4 hours ahead, keeping them separate. Cube the avocado and toss everything together no more than 30 minutes before serving.
Can I skip the cilantro?
Yes, finely chopped parsley, dill, or even a handful of baby arugula will give you that fresh element without the soapy note some people taste.
