There’s nothing more summery than a bounty of zucchini and squash! There’s so much to do with this classic combination of vegetables, from casserole to roasting them. But the easiest? Grilled zucchini and squash! Throw this pair on the grill with Italian-style spices and grill until they’re charred and tender. It’s the perfect side dish for a grilled meal on the patio. We can almost feel the grass under our toes and the summer sun! Here’s what to do.

Ingredients for grilled zucchini and squash

There’s not much you need besides the vegetables here! This grilled zucchini and squash is very basic, but uses just the right ingredients to get big flavor. On their own both are very bland, but amp them with these Italian seasonings and they taste incredible. Here’s what you need for grilled zucchini and squash:

  • Medium-sized zucchini: You’ll want a zucchini that’s not too small or too big. Zucchini or summer squash that are too large can get stringy and seedy.
  • Medium-sized summer squash: Same notes as for the zucchini!
  • Dried basil and oregano: to bring in the Italian flavor
  • Garlic powder and onion powder: rounds out the amazing flavors
  • Olive oil & kosher salt

How to cut zucchini and summer squash for grilling? There are a few ways we like to do it. Here’s a little breakdown:

  • Rounds. You can slice the zucchini and squash into 1/2-inch thick rounds.
  • On the bias (diagonal). If you cut diagonally or “on the bias”, you get larger, most interesting shapes.
  • Planks. You also can cut the vegetables width-wise into long planks: see this grilled zucchini.
