Nothing’s better (or easier) than this One Pan Corn and Zucchini Pesto Orzo Casserole with crispy, crunchy cheddar on top. Made using healthy vegetables and herbs, this bake is so darn easy, and so darn delicious. It’s made entirely in one pan and in under an hour. Grab some orzo pasta, plenty of herbs, and all the summer zucchini and corn that you can find. Toss everything together in a baking dish, then add creamy Havarti and sharp cheddar cheese. Bake until the top is crispy and crunchy. Simple, but SO GOOD.

With the abundance of summertime zucchini, corn, and herbs, I’m doing all I can to use everything up before the season ends. I’m overwhelmed with ideas, but that’s a good thing, and very exciting! I love this time of year so much.

Before leaving for Mexico, I was trying to use up some of the herbs we had in the greenhouse. You’re going to hear me say this again and again over the next few weeks, but the amount of basil we have is unreal. So much basil, so lots of basil recipes coming soon!

I thought I would highlight the fresh zucchini and corn with this recipe. It’s the perfect all-in-one dinner and it takes no time to prepare.

The background

Do you guys remember the caprese bake I made a while back? While that dish inspired this one. I LOVED that method of cooking orzo in the same pan as everything else. Not only is it super easy, but the orzo ends up tasting even more delicious because it becomes infused with the flavors of the dish.

I wanted to take that cooking method and apply it to this recipe, just switch up the flavors and summery ingredients.

The details

The recipe starts and ends in the same baking dish.

I like to use a mix of zucchini and yellow summer squash, but you can use either/or for this dish. Give them a nice thin slice, then toss with olive oil, garlic, shallots, fresh thyme, and some Italian seasoning.

Roast the zucchini to help remove the water and get the cooking process moving along.

When the zucchini is ready, add the corn, the orzo, the basil pesto, and some chili flakes for a little heat.

Toss everything together, then pour over the water, so simple. The water cooks the pasta just as if we’d boiled it on the stove. Once the water is in, bake another 10 minutes or so. Allow the water to cook into the pasta, then stir, and sprinkle over the cheese. Now finish baking!

Finish it up and eat

When the sauce is bubbling and the cheese has melted, pull the pan out. If there’s a lot of oil on top from the jar of pesto, just drain that off and save it for dipping with bread (YUMMM).

Top with plenty of fresh basil and that’s literally it. SO SIMPLE, SO DELICIOUS! And I love that there’s basically no prep or extra dishes.

Simple but delicious really is the key! Especially during these fun summer days.

Instructions 

  • 1. Preheat the oven to 400° F.
    2. In a 9×13 inch baking dish, combine the zucchini, olive oil, garlic, shallots, thyme, Italian seasoning, chili flakes, salt, and pepper. Roast 15 minutes. Pull the zucchini out of the oven. To the same pan, add the corn, orzo, and pesto. Pour over 2 1/2 cups of water and stir to combine. Return the dish to the oven and bake for 12-15 minutes, until most of the water has cooked into the pasta, but not all of it.
    3. Stir the pasta around, then sprinkle over the cheeses. Bake another 10 minutes, until the cheese has melted and the sauce is bubbling. If there's a lot of oil from the pesto on top, drain off the excess. Top with fresh basil!

    I was so excited to use fresh summer produce from my CSA box in this recipe but it was a fail. One tablespoon of dried herbs is overpowering and 2.5 cups of water was not nearly enough to cook the pasta, I kept having to add more until it was mostly cooked. Too greasy with the olive oil, cheese, AND pesto. This needed way more testing before sharing.

    1. Tieghan Gerard says:

      Hi Dana! I am SO sorry you didn’t enjoy this recipe! I really appreciate the feedback and I will look into some changes! xT

  6. Marissa Farbo says:

    How would you recommend preparing this for freezing and reheating? Looking To make this for a soon to be mom And was hoping The instructions at the end Would give some insight on freezing and reheat Period

    1. Tieghan says:

      Hi Marissa,
      I would make the recipe through step 3 and freeze. Your friend can then reheat from frozen on low, I would say 300F covered with foil. I hope this helps! xx

  12. Melissa says:

    Going to make tonight but have a somewhat stupid question regarding the corn. I plan on cutting the corn off the cob for the recipe. Do I need to cook the corn on the cob before cutting the kernals off?

    I also plan on using zucchini and squash. Do both need to be roasted prior to adding the other ingredients?

    1. Tieghan says:

      Hey Melissa,
      Not stupid at all:) You do not need to cook the corn first. Yes, you can roast both the zucchini and the squash as directed in step 2. I hope this helps! xT

    I’ve made this over 10 times. I love it! Such an easy dish to throw together.

    I’m curious if this is one you can freeze well? I think I’m most nervous about the zucchini being super mushy after freezing. Let me know your thoughts!

    1. Tieghan says:

      Hey Brisa,
      Happy Sunday! I appreciate you making this recipe so often and your comment, so glad to hear it is always a hit! I’ve never tried freezing this, but I think it’s worth a try! x
