Yes, my grilling obsession continues mostly because it is 115 degrees outside and I have no intention of turning on the oven again until it cools down…sometime in October!!

Those of you that have been hanging out with me for the past few years already know that my favorite vegetable is zucchini! I have sautéed it, stuffed it, deep fried it, and tossed it into several different salads. This time I grilled it to create a pizza recipe that is out of this world!

Recipe and images updated on May 13, 2022 – zucchini cut on the diagonal is much easier to grill!!

Ingredients needed

Ingredients to make grilled summer squash pizza.
  • We start with homemade Italian pizza dough or store-bought, your choice.
  • Olive oil to grill the squash, zucchini, and red onion; and also to keep the pizza from sticking to the grill.
  • Minced garlic is mixed with additional oil to create a light, flavorful sauce, that is topped with a light sprinkling of mozzarella and feta cheeses.
  • Fresh oregano and thyme add a punch of fresh flavor, but dried can be substituted.

How to make a Grilled Summer Squash Pizza

Recipe Notes & Tips

  • For those who like things spicy, sprinkle crushed red pepper flakes over the finished pizza.
  • For those who like things saucy, drizzle Balsamic Glaze over the finished pizza.
  • Substitute any other types of squash that you like.
  • Do not panic if you crust sticks to the foil and folds onto itself. Use the tongs to lift and adjust the crust the best you can. It does not need to look perfect, grilled pizzas should look rustic.

How do I make Grilled Summer Squash Pizza if I do not own a grill?

The squash can be grilled indoors on a grill pan, just like the one that I used on my grill. I use it on the grill to keep the slices from sliding through the grates.

The pizza can then be baked in a 450 degree oven until golden brown, about 8 to 10 minutes.

If using a pizza stone make sure to heat the stone while the oven is heating. Never place a cold stone in a hot oven, it will crack.

Can I use different cheese?

The original version of this pizza did not include mozzarella cheese. It was added to help keep the squash from sliding off. Gruyere, provolone, and parmesan are excellent choices as well.

What if I have leftovers?

Allow pizza to cool completely then store in an air-tight container in the refrigerator for up to 4 days. Reheat in an Air Fryer, 350 degree oven, or microwave before serving.
