This corn green bean salad trades the usual boiled-and-drowned routine for charred corn, crisp-blanched green beans, and a brown butter hazelnut dressing that actually clings to every bite. It's the side that disappears first at a cookout, and it's just as good pulled straight from the fridge the next day. Sweet, nutty, a little smoky, and never soggy.

Sweet Corn & Green Bean Salad with Hazelnuts – Easy Cookout Side

Print Recipe

A charred corn and crisp green bean salad tossed in a warm brown butter hazelnut vinaigrette.

Total Time: 30 minutes
Yield: 6 1x

Ingredients

Scale

4 ears fresh corn, kernels removed (about 3 cups)
1 lb green beans, trimmed
1/2 cup hazelnuts, toasted and roughly crushed
4 tbsp unsalted butter
1 small shallot, thinly sliced
3 tbsp sherry vinegar (or red wine vinegar)
1 tbsp Dijon mustard
2 tbsp olive oil
1/4 cup fresh basil or tarragon, torn
Flaky salt and black pepper, to taste

Instructions

Bring a large pot of salted water to a boil. Blanch the green beans for 3-4 minutes until bright green and crisp-tender, then plunge into an ice water bath and drain well.
Heat a dry cast-iron skillet over high heat. Add the corn kernels in a single layer and cook without stirring, 3-4 minutes per side, until well charred in spots.
While the corn cooks, combine the sliced shallot and sherry vinegar in a small bowl and let it sit to quick-pickle.
In a small saucepan, melt the butter over medium heat and cook, swirling often, until it turns amber and smells nutty, 3-5 minutes. Stir in the crushed hazelnuts and cook 30 seconds, then remove from heat and let cool slightly.
Whisk the pickled shallot and vinegar with the Dijon mustard and olive oil, then whisk in the warm brown butter hazelnut mixture.
Toss the charred corn, blanched green beans, dressing, and herbs together. Season with flaky salt and black pepper. Serve warm or at room temperature.

Notes

If using frozen corn, thaw and pat it very dry before charring or it will steam instead of brown. Store the dressing separately if making ahead, and toss everything together just before serving so the beans keep their color and snap.

Here’s the problem with most corn and green bean salads: the corn gets boiled into blandness and the beans get boiled into gray mush, then the whole thing is buried under a generic vinaigrette to compensate. This recipe fixes both failures at the source. The corn gets charred in a dry, screaming-hot skillet (or on the grill) so the sugars caramelize instead of leach into water — you want real brown spots, not a golden tan, because that’s where the flavor lives. The green beans get a fast blanch-and-shock: boiled just until they turn bright green and lose their raw squeak, then plunged straight into ice water to stop the cooking. That ice bath is the step people skip, and it’s the whole reason store-bought-tasting bean salads turn drab and limp while this one stays snappy.

The other move that sets this corn green bean salad apart is the dressing. Instead of plain olive oil and vinegar, you brown butter until it smells nutty and faintly toasted, then swirl in crushed hazelnuts right off the heat so they warm through without scorching. Browning butter is really just controlled Maillard reaction — the milk solids toast while the fat stays liquid — and that toasty, slightly caramel note is a natural match for sweet charred corn and earthy hazelnuts. Whisked with a shallot that’s been quick-pickled in the vinegar (just a five-minute soak to knock off the raw bite), it turns into a warm, savory dressing with real body, not a thin oil-and-acid splash that slides off the vegetables.

Two mistakes will flatten this salad if you’re not careful. First, don’t dress the beans while the dressing is piping hot straight off the stove — let it cool for a minute or two, or the residual heat will start cooking the beans further and dull their color. Second, don’t walk away from the hazelnuts once they hit the butter; they go from toasted to bitter fast, so pull the pan the second they smell fragrant. No hazelnuts on hand? Toasted pecans or sliced almonds work fine, just adjust the toasting time down since they’re smaller. For a heartier version, fold in crumbled feta or goat cheese, or add torn basil or tarragon at the end for a fresh, herbal lift against all that richness.

Frequently Asked Questions

Can I make this corn green bean salad ahead of time?

Yes. Blanch the beans, char the corn, and make the dressing up to 2 days ahead, storing each separately in the fridge. Toss everything together right before serving so the beans stay bright and crisp instead of going soft in the dressing.

Can I use frozen or canned corn instead of fresh?

Frozen corn works well as long as you thaw it completely and pat it bone-dry before it hits the hot skillet, otherwise it will steam rather than char. Canned corn is too soft and wet to caramelize properly, so it's not recommended for this recipe.

What can I substitute for hazelnuts?

Toasted pecans or sliced almonds are the closest swap and work well in the brown butter. Just pull them from the heat as soon as they're fragrant, since smaller pieces toast faster and burn more easily than hazelnuts.

Should this salad be served warm or cold?

It's best served warm or at room temperature, right after tossing, when the brown butter dressing is still loose and glossy. It also holds up well chilled the next day, though the dressing will firm up slightly in the fridge.

How do I keep the green beans from turning gray or dull?

Shock them in ice water immediately after blanching to stop the cooking, and don't toss them with the dressing while it's still hot. Both steps prevent the residual heat from overcooking the beans and dulling their bright green color.
