45-day trial to cook with our cast iron

There’s a moment in late summer when the markets are overflowing with zucchini, sweet corn, and big bunches of basil. That’s where this skillet pasta starts.

The trick? Toss your corn cobs into the pasta water for the last few minutes of boiling. It pulls out every last bit of sweetness and adds a depth you may not be able to name, but you’ll taste it.

Cook your zucchini low and slow until golden and jammy. Like onions, squash caramelizes beautifully when given a little time—and that caramelization does wonders for your cast iron seasoning too. Use your biggest skillet (we like the No.12) to give everything space to brown, not steam.

Then add your al dente pasta and stir in generous spoonfuls of pesto. Everything comes together in one pan for an easy, late-summer meal made to share.

Make it your own

  • Add thinly sliced onions to the zucchini for extra sweetness.
  • Fold in cooked sausage or crispy bacon if you want something heartier.
  • Swap the pesto: try arugula, mint, or a spicy Calabrian chile version.

Recipe: Zucchini and Corn Pasta with Pesto

Yield: 6 - 8 servings

Instructions

1.

Slice the zucchini into thin half moons. Shuck your corn and half the cobs.

2.

In your No.12 Field Skillet, add a generous glug of olive oil and warm over medium heat. Add the zucchini with a large pinch of salt and pepper. Let it cook, stirring occasionally, until deeply golden and caramelized. Don’t rush it—this step brings out deep flavor and helps build up your skillet’s seasoning.

3.

Meanwhile, bring a large pot of salted water to a boil. Add your pasta and cook until a few minutes shy of al dente. In the final 2–3 minutes of cooking, toss in the corn cobs.

4.

Before draining, reserve about 1½ to 2 cups of the pasta water. Then drain the pasta and remove the corn cobs. Let the pasta hang out while you deal with the corn.

5.

Once cool enough to handle, lay your cobs on a cutting board and slice off the kernels, rotating the cob as you go so that the flat side is sitting on the cutting board. (This is our go-to method so the kernels don't end up all over the floor)

6.

Add the pasta and corn to the skillet with the zucchini. Spoon in the pesto, splash in some reserved pasta water, and finish with another glug of olive oil. Toss until glossy and well coated. Taste and adjust with more salt and pepper if needed.

7.

Top with grated parmesan, torn basil leaves, or whatever herbs you have on hand. Serve straight from the skillet.


Seasoning Rating: Better

This pasta’s got everything your skillet loves: olive oil, starchy pasta water, and plenty of gentle movement.

It’s a simple, forgiving recipe that helps your cast iron stay smooth, slick, and naturally nonstick.

Seasoning Ratings:

Best—These dishes are the best options for building resilient seasoning, and surefire choices for getting tricky pans back on track.

Better—The best way to keep your skillet in great shape is to cook frequently, and cast iron-friendly dishes like these are your bread and butter.

Safe—These recipes won't strip seasoning away from your pan, but won't really add any, either.

OK—Be sure to clean up promptly. Recipes with this rating might feature acidic ingredients which can affect seasoning if not washed soon after cooking.
