Ingredients for corn salad recipe with mayo and sour cream
Here's what transforms summer picnics into unforgettable meals with creamy, crisp perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Sweet Corn Kernels 🌽 | 2 cups | Cut from 2 ears or frozen |
| Celery Stalks 🧅 | 2 whole | Thinly sliced on diagonal |
| Red Onion 🧅 | ½ cup | Thinly sliced, about 1 small |
| Mayonnaise 🥫 | ¾ cup | Full-fat for creaminess |
| Sour Cream 🥛 | ½ cup | Full-fat preferred |
| White Vinegar 💧 | 1 tbsp | For brightness |
| Granulated Sugar 🍚 | 1 tbsp | Balances tanginess |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Fresh Dill 🌿 | 2 tbsp | Chopped, optional garnish |
The celery and red onion are non-negotiable for that signature crunch—look for stalks that snap cleanly and onions with crisp layers. Trader Joe's always has the best celery, and I swear by their sweet corn too. For the dressing, Duke's or Hellmann's mayo gives the richest texture, but any full-fat brand works. The secret? Thinly slicing the celery on the diagonal—this creates more surface area for the dressing to cling to, making every bite irresistible. If you're using frozen corn, thaw it first and pat dry to avoid a watery salad.
No mayo? Greek yogurt works in a pinch—just add an extra tablespoon of sour cream to keep it creamy. Swap the white vinegar for apple cider vinegar if you prefer a fruitier tang. The sugar is key here—brown sugar adds depth, but white works too. Fresh dill is ideal, but dried dill at one-third the amount gets you close. For extra crunch, add chopped radishes or bell pepper—whatever you've got on hand. The dressing can be made ahead, but hold off on adding the celery and onion until serving to keep them crisp.
This salad tastes even better the next day—the flavors meld beautifully in the fridge. Store the dressing separately in an airtight container for up to 3 days, and the veggies wrapped in a damp towel for 2 days. For picnics, pack the dressing and veggies in separate containers—toss right before serving. The dressing alone keeps for 5 days in the fridge, making it perfect for meal prep. If you're serving a crowd, double the recipe—it disappears fast!
Why You'll Love This Recipe
- No Chopping Chaos: I swear by this one—just cut the celery into big chunks and slice that red onion thin enough to taste but thick enough to stay intact. The corn? Straight off the cob or frozen, no fuss. My kids help with this part, and we still have time for cartoons before dinner.
- Creamy Crunch Magic: That mayo-sour cream combo? It’s where it’s at. The sour cream keeps it light, while the mayo clings to every sweet kernel like a hug. Add a pinch of salt and a squeeze of lemon, and suddenly, your bowl is ridiculously good—crisp, cool, and impossible to stop eating.
- Potluck Proven: Between us, this is my go-to for picnics, BBQs, or even a last-minute potluck. It travels well (won’t wilt or get soggy), pairs with everything—grilled chicken, burgers, or just a slice of bread—and honestly? People always ask for the recipe. It’s that reliable.
- Leftovers That Don’t Suck: I make a big batch on Sunday, and it’s still fresh by Friday. The red onion mellows out, the celery stays crisp, and the dressing doesn’t separate if you store it right. Plus, it’s weirdly budget-friendly—corn’s cheap in season, and mayo/sour cream stretch far. My secret weapon for lazy nights.
Step-by-step instructions for creamy corn salad
Here's how to blend crisp celery and sweet corn into velvety perfection with just a few simple steps.
Prepare the Celery and Onion
Cut the 2 whole celery stalks into thin diagonal slices—this creates more surface area for crunch. You'll want pieces about ¼-inch wide that will stay crisp even after mixing. Transfer them to a large mixing bowl.
Next, thinly slice the 0.5 cup red onion (about 1 small onion) into paper-thin rings. The diagonal cut works here too for even texture. Add these to the bowl with the celery. Let them sit for 2-3 minutes while you work—they'll soften slightly but still hold their bite, which balances the creamy dressing perfectly.
Mix the Creamy Dressing
In a separate medium bowl, combine the 0.75 cup mayonnaise and 0.5 cup sour cream. Use a whisk or fork to blend until smooth—this ensures no lumps in your final salad. The full-fat versions are key here; they create that ultra-creamy texture without breaking down when mixed with acidic ingredients.
Add the 1 tbsp white vinegar, 1 tbsp granulated sugar, 0.5 tsp salt, and 0.25 tsp black pepper to the mayo mixture. Whisk vigorously for 30 seconds until fully incorporated. The sugar and vinegar will brighten the flavors while balancing the richness of the dairy. Taste a small spoonful—it should be tangy-sweet with just a hint of saltiness.
Combine All Ingredients
Add the 2 cups fresh sweet corn kernels to the celery and onion in the mixing bowl. Pour the creamy dressing over the top and gently fold everything together using a rubber spatula. Be careful not to mash the corn—you want those kernels to stay intact for texture contrast. The salad should look vibrant with creamy streaks throughout.
Stir in the 1 tbsp lemon juice and 2 tbsp fresh dill. The lemon juice adds a fresh zing that cuts through the richness, while the dill brings an herbal brightness. Mix well and let the salad sit at room temperature for 10 minutes—this allows all the flavors to meld together beautifully.
Chill and Serve
Transfer the corn salad to an airtight container and refrigerate for at least 30 minutes before serving. Chilling enhances the flavors and lets the dressing fully coat each ingredient. The celery will stay crisp while the corn absorbs the creamy dressing perfectly.
When ready to serve, give it one final gentle stir. The salad should be thick but still spoonable, with visible corn kernels and celery slices throughout. Garnish with extra dill if desired—this is where you can really make it look special. Serve immediately over ice for a refreshing summer dish or enjoy at room temperature for a creamy side that pairs perfectly with grilled meats or sandwiches.
Pro Tips For Making Corn Salad Recipe With Mayo And Sour Cream
- CHILL THE CORN FIRST: I learned this the hard way—dumping warm corn straight into mayo and sour cream turns the dressing into a sad, greasy mess. Cut the kernels and plunge them in ice water for 10 minutes before mixing. The shock stops the cooking and keeps the texture crisp, not mushy.
- SLICE ONIONS THIN AND SOAK: Red onion adds bite, but too much raw onion overwhelms the creamy base. Thinly slice the rings (almost translucent) and toss them in cold water for 5 minutes to mellow the sharpness. Drain well—you want flavor, not a mouthful of tears.
- MIX DRESSING LAST MINUTE: Mayo and sour cream separate when sitting too long, and the dressing can turn grainy. Keep the mayo and sour cream separate until you’re ready to toss everything together. Stir in just before serving—this keeps the texture smooth and the flavors bright.
- USE CELERY FOR CRUNCH, NOT FILLER: I used to dice celery into tiny cubes, thinking it would blend better, but that just makes the salad soggy. Cut it into matchsticks—long, thin pieces that hold their shape. The crunch is what keeps this salad from feeling like a dense side dish.
Storing and reheating this corn salad recipe with mayo and sour cream
Dressing Storage Secrets
The creamy dressing is the heart of this salad, and it stores beautifully when kept separate. Whisk it together in a glass airtight container (I love Pyrex with snap-on lids) and refrigerate for up to 5 days.
The full-fat mayo and sour cream maintain their texture perfectly—just give it a quick stir before using. For extra insurance, press plastic wrap directly onto the surface to prevent a skin from forming. 🥫
Veggie Freshness Tricks
Celery and red onion lose crispness quickly, so store them separately in a damp paper towel wrapped inside a ziplock bag. This keeps them fresh for 2 days in the fridge.
For longer storage, blanch the celery in boiling water for 1 minute, then shock in ice water before storing—this preserves crunch for up to 5 days. The corn can be kept raw in the fridge for 2 days or frozen for 3 months (thaw before using).
Reheating for Maximum Crunch
This salad tastes even better the next day, but if you need to reheat, do it gently. Spread the dressing and veggies on a microwave-safe plate and heat for 30 seconds on 50% power.
For stovetop reheating, warm in a nonstick skillet over low heat with 1 tablespoon water for 2 minutes—this prevents drying. The key is speed: reheat just until warm, not hot, to preserve texture. 🌡️
Picnic Packing Hacks
For outdoor gatherings, pack the dressing and veggies in separate leak-proof containers (I use Bentgo Glass containers). Toss them together right before serving to maintain crispness. If you're worried about melting, chill the containers with ice packs during transport.
For a no-mess option, bring individual small jars with dressing and a separate container for the veggies—just shake and eat!
Freezer-Friendly Adaptations
While the full salad doesn't freeze well, you can freeze the dressing alone for up to 3 months. Thaw in the fridge overnight, then stir in fresh veggies when ready to serve.
For a frozen version of the salad, mix everything except the celery and onion, freeze in single-serving portions, then add fresh veggies after thawing. This works best for corn-heavy portions where crunch isn't critical. ❄️
Make-Ahead Timeline
Plan ahead with this 3-step timeline: Make the dressing 1 day ahead, prep the veggies 4 hours ahead (store separately), and combine 30 minutes before serving. This gives you maximum flavor development without sacrificing texture.
The dressing can even be prepped 2 days ahead if stored properly—just whisk again before mixing. The celery will stay crisp if you slice it no more than 6 hours ahead and keep it chilled. 📅
Nutrition facts
Frequently asked questions
Can I use Greek yogurt instead of mayo in this creamy corn salad?
Yes, but you'll need to adjust the texture. Replace the mayo with ½ cup Greek yogurt and add an extra ¼ cup sour cream to maintain creaminess. The salad will be lighter but still rich. For extra tang, add ½ teaspoon Dijon mustard to the dressing.
How do I keep the celery from getting soggy in the dressing?
Slice the celery no more than 30 minutes before mixing with the dressing—this preserves its crispness. For extra insurance, toss the celery in 1 teaspoon lemon juice before adding it to the salad. Also, chill the salad for at least 30 minutes before serving to let the flavors meld without softening the veggies.
What's the best way to serve this corn salad?
This creamy salad pairs perfectly with grilled meats like chicken or pork chops, or as a refreshing side for summer picnics. For a restaurant-style presentation, serve it over a bed of ice in a chilled bowl. It's also delicious as a filling for sandwiches or wraps—just add a sprinkle of paprika for extra flavor.
Can I make this salad without fresh corn?
Use 2 cups frozen corn kernels (thawed and drained) or 1 can (15 oz) corn (rinsed to remove excess liquid). For a twist, try roasted corn kernels—toss them with 1 teaspoon olive oil and ½ teaspoon smoked paprika before mixing into the salad for a smoky depth of flavor.
Why did my dressing separate?
This usually happens when acidic ingredients (like vinegar or lemon juice) are added too quickly or the mayo/sour cream isn't full-fat. To fix it, whisk in 1 teaspoon cold water or 1 teaspoon Dijon mustard to help emulsify. For future batches, add the vinegar and lemon juice slowly while whisking continuously. The dressing should be smooth and creamy, not grainy.
