Few things are as satisfying in gardening as enjoying the fruits and vegetables of your labor! Our family truly enjoys growing summer squash and zucchini—as long as the vine borers leave them alone. This year was tough!

Summer squash on the grill takes only moments to prepare. Most of the time is just slicing! Season simply yet effectively for a tasty veggie you’ll enjoy just as much for leftovers as the day you make it (if not more!).

Yellow straightneck or crookneck squash is so delicate, tasty, and mild that even your kids have hope of loving it! Toss yellow summer squash together with zucchini for a colorful addition to your dinner plate.

The star of this recipe is the McCormick Garlic Pepper Seasoning. This spice jar is worth its cost and makes the dish so delish.

We get ours at Weis Market.

For consistent results, it’s also important to be sure you have your tools on hand, especially your grill basket or grill wok.

This grilled summer squash recipe (and leftovers) are one of my long-standing favorites for summer veggies.

I plan to continue making these during the winter months, too, as long as we can find squash at that time, or freeze some of our harvest!

If your plans to grill are foiled by a storm or running out of gas, you can easily switch to roasting your summer squash! Simply follow the same steps – coat with olive oil and the garlic pepper seasoning. Toss and place in a Pyrex pan. Roast in your oven at about 375 degrees for 15 minutes or until desired doneness. I also toss in some carrots for a burst of color and more flavor.

  • Remove the grilled squash from heat with the rest of your meal.
  • Pour the squash into a serving bowl or platter and move the grill pan aside.
  • Enjoy! Add more seasoning if desired.

LEFTOVERS: Reheating Grilled Summer Squash to Perfection

  • Lightly coat a frying pan on medium-high heat with olive oil.
  • Get the pan hot and spread out a thin layer of the grilled summer squash and zucchini. The idea here is to sear it!
  • Set a timer for a minute or two and check for doneness. You want a little bit of sear marks on the bottom of the slices before you flip them over.
  • Once veggies are seared on the bottom, flip them over and continue to sear the other side.

  • Once both sides are done, remove from heat and enjoy!


Arguably, most foods are better the first time around. I love leftovers more than most, but some foods just aren’t as good the next day. With grilled summer squash and zucchini, I beg to differ. If you follow my recipe, you will find it just as tasty during the week, if not more so when you reheat leftover grilled summer squash!

Grilled Yellow Squash and Zucchini

We love making grilled squash and zucchini in a grill basket on my husband’s Weber grill. We lightly coat with a bit of olive oil and sprinkle on some McCormick Garlic Pepper – absolutely delicious!

I plan to freeze summer squash and zucchini slices so we can enjoy them sheet pan style over the winter. It won’t be the same, but it ought to tide us over until summer grilling season again!
