One-Pan Zucchini Corn Tomato Skillet

Recipe of the Day: One-Pan Zucchini Corn Tomato Skillet

Summer in Southern California means farmers-market tables piled high with zucchini, sweet corn, and juicy tomatoes. This one-pan skillet captures that bright, sun-warmed flavor in under 30 minutes. It is simple enough for a weeknight yet pretty enough for company. Everything cooks together in one skillet, so cleanup stays minimal and the vegetables keep their fresh texture.

The dish leans on peak-season produce for natural sweetness. A little butter and garlic bring everything together without overpowering the vegetables. Fresh basil at the end adds a fragrant finish that makes the whole pan smell like summer. Serve it as a main with crusty bread or as a colorful side with grilled chicken or fish.

Ingredients (Serves 4 as a main, 6 as a side)

• 2 tablespoons unsalted butter (or olive oil for dairy-free)
• 1 medium yellow onion, diced (about 1 cup)
• 3 cloves garlic, minced
• 3 medium zucchini (about 1.5 pounds), sliced into 1/4-inch rounds
• 3 ears fresh corn, kernels cut from the cob (about 2 cups)
• 1.5 pounds ripe tomatoes, cored and cut into 1-inch chunks (about 3 cups)
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon freshly ground black pepper
• 1/4 teaspoon red pepper flakes (optional)
• 1/4 cup fresh basil leaves, torn
• 2 tablespoons fresh parsley, chopped
• 1/4 cup grated Parmesan cheese (optional, for serving)

Instructions

1. Place a large 12-inch skillet over medium heat. Add the butter and let it melt until it foams lightly, about 1 minute. Add the diced onion and cook, stirring occasionally, until it turns translucent and soft, 4 to 5 minutes.

2. Stir in the minced garlic and cook until fragrant, 30 to 45 seconds. Do not let the garlic brown.

3. Add the zucchini rounds in a single layer if possible. Sprinkle with 1/2 teaspoon of the salt. Cook without stirring for 3 minutes so the bottoms can lightly brown, then stir and continue cooking until the zucchini is just tender but still holds its shape, another 4 to 5 minutes total.

4. Add the corn kernels, tomatoes, remaining 1/2 teaspoon salt, black pepper, and red pepper flakes if using. Gently fold everything together. Cook, stirring occasionally, until the tomatoes release some juice and the mixture is heated through, 6 to 8 minutes. The zucchini should be tender with a slight bite and the corn should be bright.

5. Remove the skillet from the heat. Taste and adjust salt if needed. Stir in the torn basil and chopped parsley. Let the skillet rest for 2 minutes so the herbs can perfume the vegetables.

6. Serve warm, topped with grated Parmesan if desired. The whole dish comes together in about 25 minutes from start to finish.

Storage and Reheating

Cool leftovers to room temperature within 2 hours. Store in an airtight container in the refrigerator for up to 4 days. Reheat gently in a skillet over medium-low heat with a splash of water or broth to loosen the mixture, stirring occasionally until warmed through, 4 to 5 minutes. Avoid high heat to keep the vegetables from becoming mushy. The skillet also reheats well in the microwave in 60-second bursts.

Substitutions and Dietary Variations

• Swap butter for olive oil to make the recipe dairy-free and vegan.
• Use frozen corn kernels (no need to thaw) when fresh corn is unavailable; add them in step 4 and cook 2 extra minutes.
• Cherry or grape tomatoes work beautifully in place of larger tomatoes; halve them before adding.
• Add a can of rinsed white beans or chickpeas in step 4 for extra protein and a heartier main dish.
• For a gluten-free meal, the recipe is already naturally gluten-free. Serve over cooked quinoa or with gluten-free bread.

Food Safety Guidance

Wash all produce thoroughly under running water before cutting. Keep raw vegetables separate from any raw meat, poultry, or seafood during prep. Use a clean cutting board and knife.
