One-Skillet Zucchini, Corn, and Tomato Pasta

↓ Jump to recipe card

Late summer hands you zucchini, corn, and tomatoes all at their best in the same week, and this skillet is built to use all three without turning any of them mushy or making the pasta an afterthought. Everything cooks in stages in one pan — zucchini seared first and set aside, corn charred next, tomatoes blistered into a light sauce last — so each vegetable keeps its own texture instead of collapsing into a single soft mass by the time it hits the table.

Sear the zucchini first, then get it out of the way

Zucchini releases a lot of water once it’s crowded or left in the pan too long, which is the single most common way this kind of dish turns watery and bland instead of bright and browned. Searing it in one layer, then pulling it out while the corn and tomatoes take their turn, keeps it from stewing in everyone else’s liquid. It goes back in right at the end, just long enough to warm through.

The pasta water is doing the sauce’s job

There’s no cream, no jarred sauce, and no roux here — the glossy, clingy texture comes entirely from starchy pasta water added a splash at a time while tossing everything together off the heat. It’s the same trick that makes a good cacio e pepe work, just pointed at a much more casual, vegetable-forward dinner.

A genuinely flexible weeknight base

This is the kind of dish that tolerates substitution well — swap in whatever squash, cherry tomato variety, or short pasta shape is actually sitting in the kitchen, and the technique still holds. It’s less a fixed recipe than a method for turning a produce-heavy grocery haul into dinner before any of it has a chance to go soft in the crisper drawer.

Tips & variations

• Sear the zucchini in a single uncrowded layer — piling it in the pan steams it instead of browning it, and browning is where the flavor actually comes from.
• Cutting corn straight off the cob gives a sweeter, snappier bite than thawed frozen kernels, but frozen corn works fine if fresh isn't in season where you are.
• Save more pasta water than you think you need. It's the easiest way to loosen the sauce without diluting the flavor the way plain water would.
• This scales down easily for two — halve everything except the garlic and red pepper flakes, which taste better slightly generous.

Ingredients

For the pasta and vegetables

• 12 oz short pasta (fusilli, penne, or shells)
• 2 tablespoons olive oil, divided
• 2 medium zucchini, halved lengthwise and sliced
• Kernels from 2 ears corn (about 1.5 cups)
• 1 pint cherry tomatoes, halved
• 3 cloves garlic, thinly sliced
• 1/2 teaspoon red pepper flakes (optional)
• Salt and black pepper, to taste

To finish

• 1/2 cup grated Parmesan, plus more for serving
• 1/4 cup torn fresh basil
• 1 tablespoon butter (optional, for a silkier sauce)
• Zest and juice of 1/2 lemon

Instructions

1. Bring a large pot of salted water to a boil. Cook the pasta until just al dente, reserving 1 cup of pasta water before draining.
2. While the pasta cooks, heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add the zucchini in a single layer and cook 3-4 minutes per side, until golden at the edges. Remove to a plate.
3. Add the remaining oil to the same skillet. Add the corn kernels and cook 3 minutes, stirring occasionally, until lightly charred in spots.
4. Add the garlic and red pepper flakes, cook 30 seconds until fragrant, then add the cherry tomatoes. Cook 4-5 minutes, pressing a few tomatoes with a spoon to release their juices and build a light sauce.
5. Return the zucchini to the skillet along with the drained pasta. Toss to combine, adding a splash of the reserved pasta water at a time until everything is loosely coated and glossy.
6. Remove from heat. Stir in the Parmesan, butter (if using), lemon zest and juice, and season with salt and pepper to taste.
7. Top with basil and extra Parmesan just before serving.
