Ingredients for Corn Cucumber Salad
The neat part about summer salads is that they don’t need to be overly complicated. This one only takes seven ingredients.

- Cucumber
- Sweet corn
- Red onion
- Fresh Cilantro
- Lemon
- Ground Cumin
- Salt and Pepper
Key Ingredient Roles
These ingredients sound pretty straightforward, right? I like to take a brief look at each of them because they each bring something to this corn and cucumber salad. I’ll usually include some tips and tricks for selecting and using these ingredients here, too.
Cucumber
1 cucumber, peeled and diced
I like fresh cucumber in a salad because it adds a mild, refreshing sweet flavor. The thing to remember is to wait to peel and cube it until you’re ready to assemble this salad. Cucumbers can get slimy if you try to do it ahead of time. They’re better when they can stay crisp!
If you use an English cucumber, it’s less necessary to peel it because it has a thin and tender skin that is easy to chop and chew. I’ll use a cucumber straight out of my garden, though. Garden cucumbers usually have a thicker, tougher skin that will have to be removed.
Sweet Corn
2 cups sweet corn
Sweet corn adds an attractive texture and flavor to any summer-themed salad. I like to roast a few ears of corn, and then remove the corn. Boiling or grilling it would work, too. You could also use a bag of frozen corn. I’m not a huge fan of using canned corn for salad, though it’s doable in a pinch.
Comparison of Sweet Corn Options
Here’s a quick comparison of corn on the cob, frozen corn, and canned corn so you can choose the one you think works best.
| Corn Type | How to Use It |
|---|---|
| Fresh corn | Cook, cool, then slice kernels off the cob. Grilled corn adds smoky flavor. |
| Frozen corn | Thaw fully and drain well. Cook first if the package says it is not ready-to-eat. |
| Canned corn | Drain and rinse to reduce excess liquid and canned flavor. |
Red Onion
1/2 cup red onion, sliced
Red onion has a sweet-pungent flavor that goes well on salads and sandwiches. Raw red onions’ flavor is a bit more intense than white onions, which can cause some picky eaters to pick them off a salad. I like it in moderation, and usually mixed with other flavors like the sweet corn.
If you prefer your red onion to have a milder flavor, soak it in cold water to draw out the flavor before using. You could also use a white onion, if you like.
Have your red onions been sitting in a refrigerator drawer for a while? I’ve been there. Sometimes they will go bad if they’ve been in the fridge long enough for me to forget why I even bought them. If you’re in this position, make sure the red onions have no soft or mushy spots, visible mold, or strong odor before using them. If they have any of these things, discard them and get new red onions.
Fresh Cilantro
1/2 cup fresh cilantro, chopped
Cilantro brings a fresh, mild, bitter-sweet, citrus-like flavor to this salad. If you have a chance to choose between varieties of cilantro, go with lemon cilantro, which pairs well with the lemon juice and spices.
If you guessed that there are also cilantro varieties that go well on mildly spicy dishes like tacos, you might do well on Jeopardy! Here’s a quick chart comparing types of cilantro and what they’re used for.
| Cilantro Variety | Best Used For | Flavor / Texture Notes | Good Fit for Corn Cucumber Salad? |
|---|---|---|---|
| Leisure Cilantro | Salsas, salads, fresh garnishes, meal prep | Classic cilantro flavor; slower to bolt, so it’s good for leafy harvests | Yes — a great all-purpose choice |
| Slow Bolting Cilantro | Summer salads, tacos, pico de gallo, cold dishes | Similar to standard cilantro but bred to stay leafy longer | Yes — especially good for summer recipes |
| California Long Standing | Fresh garnishes, salads, sauces, bowls | Reliable leaf production with familiar cilantro flavor | Yes — mild and versatile |
| Delfino Cilantro | Garnishes, delicate salads, plated dishes | Fine, feathery leaves with a softer look | Yes — best when presentation matters |
| Lemon Cilantro | Citrus salads, seafood, cucumber salads, corn salads | Brighter, more lemon-forward flavor | Excellent — pairs naturally with lemon dressing |
| Moroccan Cilantro | Herb sauces, grain salads, North African-inspired dishes | Fresh, herbal, and bold | Yes — especially with cumin or lemon |
| Costa Rica Cilantro | Salsas, fresh toppings, warm-weather gardens | Traditional cilantro flavor; often grown for leafy use | Yes — use like regular cilantro |
Lemon Juice
Juice from 1 Lemon
Freshly squeezed lemon juice has a bolder, fresher flavor than bottled lemon juice does. Just chop one in half widthwise and juice it with your citrus juicer.
Cumin
1 teaspoon cumin
Cumin adds a mildly spicy flavor that pairs well with the mild sweetness of the cucumber and corn and the sour flavor of the lemon. Like most spices, the exact amount can be adjusted to your liking.
Salt and Pepper
Salt and pepper to taste
I’ll usually just go with a pinch of salt to bring out the sweet corn’s flavor. The pepper adds its classic woody, earthy spice.

Variations for Corn and Cucumber Salad
I think this summer-themed salad makes a good side dish on its own. You can make it your own or even make it a healthy main dish with some creative variations.
- Try grilled or roasted corn for an additional layer of flavor in this corn and cucumber salad.
- Add some diced avocado for a touch of creaminess.
- Instead of cumin and cilantro, try dried basil and fresh parsley or dried oregano and fresh basil.
- Add some cooked chickpeas, black beans or kidney beans for some plant based protein in this summer corn salad.
- Grilled shrimp also makes a good lean protein addition.
- Add halved cherry tomatoes or grape tomatoes for a sweet juicy burst.
- For a “reduced salt” version, leave out the salt and add a little more fresh lemon juice.
- If life hasn’t given you lemons, freshly squeezed juice from a lime can work. Two teaspoons of apple cider vinegar can also add a bit of acidic flavor.

Serving Suggestions
I like to have this salad as a side for a light, “summer-themed” lunch or dinner. It pairs well with proteins that aren’t too healthy, like parmesan-crusted fish fillets. You could also try adding the shrimp from this shrimp avocado salad if you want.
For a “sandwich and salad,” open-faced tuna melts pair well with this corn and cucumber salad. Like the salad, the tuna melts are easily transportable in a cooler if you don’t mind eating them cold. (If the picnic area has a nearby grill, I might be tempted to use the grill to melt the cheese on the tuna melts. Just make sure you follow the picnic area rules.)
Sides that would pair well with this salad include crispy Brussels sprouts and sweet potato lentil fritters. For “soup and salad” options, I’d go for a nice, smooth one, such as sweet potato carrot soup or coconut curried butternut soup.
And, of course, there’s always easy pineapple pie and homemade ice cream for dessert!
Storage
Store leftover corn and cucumber salad in an airtight container in the refrigerator up to 2 days. The cucumber will start to lose its crispness but it will still be good.
FAQs About This Corn and Cucumber Salad
Of course, we get questions about this corn and cucumber salad! I did my best to answer the most common ones below. If you have any questions that aren’t answered here, feel free to ask in the comments section, and we’ll try to answer them.
Can I prep this salad ahead of time?
Although I like to assemble this salad right before serving, it can also be made a few hours ahead of time and chilled. I prefer not to make it much more than eight hours ahead of time to keep some of the vegetables from getting too “soggy.” Leftovers can be stored in the fridge for up to 2 days; much longer than that, and the vegetables may start to go bad.
Can I use frozen corn?
I prefer to use corn on the cob, but a bag of frozen corn will work too. Follow the package instructions to prepare it for addition to this salad. (It will likely need to be heated up, though not always.)
Canned corn can be used, as well, though it’s very much my third option. I only use it when I don’t have any corn on the cob or frozen corn available.
Why did my cucumbers use their crispness?
This can happen if cucumbers are left to sit for too long! This happens faster after they’ve been taken out of the refrigerator and sliced, so I’ll usually wait to slice them until I’m nearly ready to add them to the salad.
I’ve stored it for about a day or so and now there’s some water pooled on the bottom of the bowl! Why is this?
This is actually fairly common in corn and cucumber salad that was made ahead! It can help to wait until you’re ready to serve it before adding the salt because it can draw out the water in the corn and cucumbers. It can also be mitigated by reducing or eliminating the salt and using the salad within two days of making it.
