Oh HELLO there summer in a bowl. So nice to meet you and eat you and love on you straight through September.
It is *officially* corn season, and this tomato corn salad is one of the easiest, sweetest summer salads you can, and should, make.
Fresh sweet corn straight from cobs, ripe juicy tomatoes, creamy avocado, and scads of fresh basil are combined with a tangy buttermilk dressing that is, as the kids say these days, just so very, very extra.
This salad is the perfect side dish for just about anything (we had it with grilled steak) and makes a great picnic or potluck option. But it’s also entirely appropriate to eat a bowl all on it’s own and call it dinner. Or lunch. And a few spoonfuls of the leftovers make for a delightful midnight snack.
How to Cook Corn for Tomato Corn Salad
There are a number of ways to cook the corn for this salad, and each are delicious in their own right. Grilled is our favorite for that slightly smoky flavor (plus one less dish to clean!).
- Grilled: grill the corn whole in their husks over high heat. Turn a quarter of a turn every 5 or so minutes, until the husks are charred and the corn is tender, about 20 minutes total.
- Boiled: remove the husks and silks from the corn. Drop the whole cobs into boiling water, cover, reduce the heat to medium to maintain a simmer, and boil for 5-7 minutes, until the corn is tender but still bright.
- Sautéed: slice the kernels from the cob. Heat a tablespoon of olive oil over medium low heat until shimmering. Add the kernels and sautee, stirring frequently, until the corn is tender, but not soft, about 10 minutes.
- Raw: Skip the cooking entirely and make this salad with raw kernels! Simply slice the kernels from the cobs, and proceed with the salad.
How to Make Buttermilk Vinaigrette
Put the oil and vinegar down, and take a few minutes to make this creamy, tangy buttermilk dressing for your tomato corn salad.
I like to make this dressing in the food processor. This ensures the garlic gets nice and pulverized, and the dressing turns out creamy, but not too thick.
Combine buttermilk, garlic, sour cream or greek yogurt, lemon juice or white vinegar, some dijon mustard, salt, and a few turns of cracked black pepper. Then blend it real good. Taste the dressing. Too tart? Add more sour cream or greek yogurt. Too rich? Add more lemon juice or vinegar.
Add some chopped chives to the dressing and give it a few pulses to incorporate them. You’re done. Wasn’t that easy?
The recipe below makes a generous portion of dressing, and you’ll only need half. Leftovers keep in the fridge for about a week, and will become thicker as it chills. Drizzled the dressing over your favorite green salad or use as a dip for sliced veggies.
How to Make Tomato Corn Salad Step-by-Step
Whether your grill, sautee, or boil the corn, you’re only thirty minutes away from this delightfully sweet and flavorful summer salad. Traditional tomato corn salad is typically tossed with a vinaigrette, but I’m shouting out to my southern roots by tossing this version with creamy, tangy buttermilk dressing. A little goes a long way, but the flavor is unmatched.
Cook the corn using one of the methods above, then slice the kernels from the cob. Scared to slice off the kernels? Fear not – this no-fail method from Food and Wine is my go to – no mess, and all fingers intact.
Add a quarter cup of buttermilk dressing to the corn kernels, then gently toss – this step will help break up some of the kernels, and ensure the dressing gets into every nook and cranny of every single kernel.
Chop up the rest of the salad ingredients – diced avocado, quartered cherry tomatoes, diced english cucumber, and sliced green onions.
Add the veggies to the bowl, along with a generous handful of chopped fresh basil.
Fold the remaining ingredients into the salad, adding up to another half cup of dressing, until everything is evenly distributed and barely coated with the dressing. Don’t be too heavy handed with the dressing – you want the ingredients covered, but you don’t want to end up with a puddle of dressing at the bottom of the bowl or the salad will become soggy pretty darn quick.
Taste for seasoning, and add more salt and pepper if needed. Serve immediately, or chill and serve cold. This salad can be left out at room temperature for a party or potluck, but don’t leave under direct sunlight for more than an hour. Leftovers keep well for up to 2 days in the fridge (the avocado gets a little funky after that).
Tomato Corn Salad Variations
- Add cheese – feta, ricotta salata, and queso fresco are good options. Start with adding half a cup.
- Use different herbs – parsley is a nice substitute for fresh basil, or a combination of parsley and fresh oregano.
- Use red onion instead of green onions for a sharper flavor.
- Make it a meal – add black beans or diced grilled chicken.
