How To Make Grilled Zucchini and Squash

Whip up a side of grilled zucchini and squash in no time with just a few simple steps.

  • Slice: Preheat the grill to medium-high heat, about 350°F. Slice the zucchini and squash lengthwise into 1/3-inch slices.
  • Season: Place the zucchini and squash in a large tray. Season with garlic parsley salt, avocado or olive oil, and a squeeze of fresh lemon juice.
  • Grill: Grill each side for about two minutes or until lightly golden.
  • Serve: Remove from the grill and serve hot or cold.

Hot tip: If you don’t have a grill, roast the zucchini and squash in the oven at 425°F until tender.

Tips For Perfectly Grilled Zucchini & Squash

Grilling is sometimes intimidating, but with these tips, it will be a breeze. Follow along for perfectly tender grilled zucchini and squash.

  • Slice the veggies lengthwise: Trim off the stems and cut the vegetables into vertical strips. It’s easier to flip strips on the grill and they’re less likely to fall through the grill grates.
  • Cut the pieces into 1/3-inch thickness: Slice the zucchini and squash pieces into similar thickness to ensure evenly grilled vegetables.
  • Sear on an open grill: Sear the sliced vegetables on the open grill for a few minutes. Avoid closing the lid as it traps the heat and results in overheated, mushy zucchini and squash.
  • Grill on medium-high heat: Medium-high heat is ideal for the veggies to develop a crisp exterior but tender inside.
  • Avoid overcooking: Grill the vegetables for about two minutes on each side. Quickly sear to prevent overcooked soggy zucchini and squash. Use these tongs for easy flipping.

Hot tip: If you want to cut the veggies into small pieces, use a grill basket. Then you won’t be worried about any pieces falling through the grill gates.

  • Garlicky: Press a few cloves of garlic and mix with oil. Then, brush on freshly grilled zucchini for extra garlic flavor.
  • Spicy: Bring on the heat and season the veggies with red pepper flakes, cayenne, or spicy chipotle seasoning.
  • Herby: Garnish the grilled veggies with fresh parsley or basil for a light herby flavor.
  • Citrusy: Squeeze fresh lemon or lime juice over the veggies right before serving to enjoy a zesty bite.
  • Cheesy: For cheesy zucchini and squash, top the hot grilled veggies with freshly grated Parmesan cheese.

Storing Leftovers

If you have grilled zucchini and squash leftovers, refrigerate them in an airtight container to enjoy within three days. The zucchini and squash taste great cold or reheated.


For the best reheated zucchini and squash leftovers, opt for the oven or airfryer. Avoid the microwave, as the veggies tend to become too soft and mushy when microwaved.

  • Oven: In a preheated oven at 400° F, place the vegetables on an oiled baking sheet. Bake for about five minutes or until heated through.
  • Air fryer: Reheat the veggies in the air fryer for a crispy exterior. Place in the preheated air fryer at 400°F for three to four minutes or until warmed through.

Can you freeze cooked zucchini and squash?

Freezing cooked zucchini and squash is not recommended because of their high water content. If frozen, the veggies may become mushy as they defrost.
