It combines the golden sweetness of fresh (or frozen!) corn with the tender, juicy goodness of fresh zucchini.

It pairs perfectly with all kinds of summery grilled or roasted proteins like chimichurri pork tenderloin, grilled balsamic chicken, grilled chicken thighs, grilled chicken sandwiches, sheet pan BBQ chicken thighs, roasted salmon, and so on.

Note: If you’ve got plenty of room on the grill, give this grilled zucchini and summer squash a try for a similar vibe that doesn’t require the stove at all!

Why You’ll Love This Sauteed Corn and Zucchini

Now, I know some people get a little hesitant when they hear the word zucchini. We’ve all been served that sad, mushy squash at some point in our lives, and it can leave you feeling a little disappointed.

But please throw out those old memories! This fresh corn and zucchini recipe turns your typical sad zucchini, completely on its head. That’s right. More crunch, less tears. A quick sauté keeps the squash crisp in this easy side dish. Fresh lemon or lime juice right at the end lightens the whole dish up and the herbs bring that vibrant finish.

Ingredient Notes

Just a few simple ingredients, with a couple more optional additions, work together to build a perfectly balanced profile.

Fresh Zucchini

For this healthy sauteed zucchini dish, look for firm, medium-sized squash at the store or farmer’s market. When sliced up into uniform half-moons and tossed into a hot pan, they become wonderfully tender and slightly earthy.

Don’t cut them too thin if you want them to retain some crunch. 1/4 to 1/3 inch works great. Cutting them to an even thickness is key because it ensures they all cook at the exact same rate, allowing them to get that golden color, and maybe the most important part, without turning soggy.

Sweet Corn

The corn brings natural sweetness and delightful little pops of juiciness. Since summer has officially arrived, using fresh sweet corn cut straight off the cob will give you the absolute best snap and flavor.

However, if you only have high-quality frozen corn on hand, that works too! Letting a portion of the corn get deeply caramelized and charred in the skillet brings out a subtle smokiness that gives the dish so much incredible depth. And no need to thaw it first.

I don’t personally love canned corn, but it would technically work too.

Onion and Garlic

This duo serves as our aromatic building blocks.The onion gets soft and sweet, while garlic adds a nice subtle kick without overpowering the fresh profile of the summer veggies. 

You could use garlic powder instead of fresh, but I prefer fresh chopped garlic here for the best flavor.

Olive Oil

My oil of choice for this dish, but feel free to sub any oil you like here. Butter is delicious as well!

Lemon Juice and Fresh Parsley

The lemon juice is the secret ingredient that ties this all together. Just a quick squeeze right at the end brightens the whole recipe. Then by tossing in your favorite fresh chopped herbs like parsley or basil, you get that perfect summer flavor.

Depending on what you’re serving this side dish with, using lime juice and cilantro instead of parsley and lemon juice will give you a different, equally delicious, flavor profile. Sprinkle with a little cotija cheese instead of Parmesan for some Mexican flair.

Salt

Good old-fashioned coarse salt and freshly cracked black pepper bring all the elements together, as always. 

Optional ingredients

I love to sprinkle this dish with a little Parmesan cheese for some savory saltiness, as well as some crushed red pepper for a little kick.

Step-by-Step Instructions

1. Heat the extra virgin olive oil in a large skillet set over medium heat. Add the diced yellow onions and cook for 4-5 minutes, stirring occasionally, until they begin to soften and turn lightly golden.

1. Add the zucchini and cook for 4-5 minutes, stirring occasionally, until it begins to soften.

1. Add the corn and cook for 3-5 minutes, stirring occasionally, until heated through.

1. Stir in the minced garlic and cook for 30-60 seconds, until fragrant.
2. Add the lemon or lime juice and kosher salt, stirring to combine. Cook for 1-2 minutes to bring the flavors together.

1. Remove from the heat, garnish with chopped fresh parsley, Parmesan, and red pepper flakes, if using, and serve.

Helpful Tips

Give the vegetables room to breathe. To get that gorgeous caramelized color on your zucchini and corn, make sure your skillet is large enough. If the veggies are piled too deep, they will end up soft and soggy.

Keep the heat up for the zucchini. A quick, hot saute allows the exterior to brown beautifully while keeping the interior perfectly crisp-tender.

While fresh summer sweet corn right off the cob is absolute perfection for this recipe, high-quality frozen sweet corn works beautifully too. No need to thaw it first.

Storage Tips

Refrigerator: Store any leftovers in an airtight container in the fridge for up to 3 to 4 days. The zucchini will soften, so I prefer to serve this fresh, but if the softer texture doesn’t bother you, it is still delicious!

Reheating: The vegetables can be reheated in a skillet, gently over low-medium heat, or in the microwave.

I would not recommend freezing this dish, as thawed cooked zucchini will get very mushy.
