This is a corn and avocado salad built around choclo โ the large-kernel Andean corn with a chewier, starchier bite than standard sweet corn โ tossed with avocado, grape tomatoes, quick-pickled red onion, and a simple lime vinaigrette. It comes together in 35 minutes and is substantial enough to eat as lunch on its own. The combination of starchy corn and creamy avocado is what makes it filling rather than just fresh.
The short version of why this works
Two things carry this salad. First, the quick lime-pickle on the red onion: soaking sliced onion in lime juice for even five minutes pulls out the harsh sulfur bite and leaves something tangy and almost sweet. Skip that step and raw onion will dominate every forkful. Second, the corn has to be cooked until genuinely tender โ choclo kernels are dense, and underdone choclo is chalky and hard to chew. Give fresh kernels the full 10โ15 minutes. Once the corn is properly cooked and slightly cooled, it absorbs the vinaigrette rather than repelling it, so every kernel carries flavor instead of just sitting in dressing at the bottom of the bowl.
Keeping leftovers crisp
Dress it at the table โ a pre-dressed salad goes limp fast, and the lime juice will start breaking down the avocado within an hour. If youโre making this ahead, store the cooked corn, tomatoes, and pickled onion together in one airtight container and keep the avocado separate, cut just before serving. That combination holds well in the fridge for up to two days. The dressed, fully assembled salad is best eaten within 30โ45 minutes; after that the avocado oxidizes and the tomatoes weep into the vinaigrette. If you do have leftovers already dressed, press a piece of plastic wrap directly against the surface of the salad before sealing โ it slows browning noticeably.
What can go wrong
- Watery dressing pooling at the bottom: Tomatoes release liquid once cut and salted. If your salad looks soupy, the fix is to salt the halved tomatoes separately, let them sit on a paper towel for 10 minutes, and pat dry before adding them. This keeps the vinaigrette from getting diluted.
- Avocado that turns grey fast: Beyond keeping it separate until serving, choose avocados that are ripe but still hold their shape when cubed โ overripe avocado breaks into mush the moment you toss the salad, and no amount of careful stirring will save it.
- Frozen choclo that stays rubbery: Frozen choclo kernels need to be fully thawed and drained before boiling, not dropped in frozen. Ice-cold kernels drop the water temperature and end up steaming unevenly, leaving some kernels soft and others still firm.
- Cilantro that wilts and turns slimy: Add cilantro last, right before serving. If it goes in while the corn is still warm, it wilts immediately and loses both texture and brightness.
- Under-seasoned salad despite following the recipe: Choclo is starchy and needs more salt than youโd expect. Season the cooking water generously โ it should taste noticeably salty โ and taste the finished salad again after the rest period, because the corn keeps absorbing flavor and often needs a second pinch of salt before serving.
Ecuadorian Corn and Avocado Salad
Equipment
- Large pot
- Medium mixing bowl
- Chef's Knife
- Cutting board
- Citrus Juicer
- Colander
- Wooden spoon or spatula
Ingredients
- 2 cups choclo (Ecuadorian corn) kernels fresh or frozen; thawed if frozen
- 2 medium ripe avocados cut into 1/2-inch cubes
- 1 cup grape tomatoes halved
- ยผ cup red onion thinly sliced
- ยผ cup fresh cilantro chopped
- 1 piece jalapeรฑo pepper finely minced, seeds removed for less heat (optional)
- 2 tablespoons extra virgin olive oil preferably cold-pressed
- 2 tablespoons fresh lime juice from about 1 juicy lime
- ยฝ teaspoon sea salt to taste
- ยผ teaspoon freshly ground black pepper to taste
Instructions
- In a large pot, bring salted water to a boil. Add the choclo and simmer for about 10โ15 minutes if fresh, or 8โ10 minutes if using thawed frozen corn, until the kernels are tender but not mushy. Drain using a colander and set aside to cool slightly.
- In a medium mixing bowl, combine the chopped red onion with a tablespoon of lime juice. Let it sit for 5 minutesโthis quick pickling process will soften the bite of the onion and add depth of flavor.
- Add the cooked corn, avocado cubes, halved tomatoes, chopped cilantro, and jalapeรฑo (if using) to the bowl with the onions.
- In a small bowl or measuring cup, whisk together the olive oil, remaining lime juice, salt, and black pepper to create a light vinaigrette. Pour over the salad and gently toss everything together with a wooden spoon to avoid breaking up the avocado too much.
- Taste and adjust seasoning as needed. Let the salad rest for 5โ10 minutes before serving to allow the flavors to mingle.
Notes
- Substitute sweet corn if choclo is unavailable; although smaller, the flavor balance is still delicious.
- Use a ripe but firm avocado to maintain texture when tossed.
- For additional protein, add grilled shrimp or black beans to transform it into a complete meal.

Your questions, answered
Can I use regular sweet corn instead of choclo?
Yes, but the texture will be noticeably different. Choclo kernels are larger, starchier, and chewier, which is what makes this salad feel substantial; sweet corn is softer and more sugary, so the result will be lighter and less filling. If choclo is unavailable, frozen hominy is a closer substitute than standard sweet corn.
How do I know when the avocado is ripe enough?
It should yield to gentle pressure from your thumb but not feel mushy. If the skin near the stem flicks off easily and the flesh underneath is green rather than brown, itโs ready. An avocado thatโs too firm wonโt cube cleanly and will taste bland; one thatโs overripe will fall apart when tossed.
Can I make this salad more filling for a full meal?
Stir in a can of drained black beans or pinto beans โ they add protein and bulk without changing the flavor profile. Cooked quinoa works too, folded in with the corn, and it soaks up the lime vinaigrette well.
Is there a substitute for cilantro if I donโt like it?
Flat-leaf parsley is the most straightforward swap โ use the same quantity and it keeps the salad fresh without the soapy note some people get from cilantro. Fresh mint also works in a smaller amount (about half the quantity) and adds a different but complementary brightness.
