Grilled Squash is one of the best easy, summer side dishes. It’s marinated in a savory combination of lemon juice, white white vinegar, fresh herbs, and olive oil then cooked to tender perfection on a grill or stove top griddle.

Summer is the perfect time of year to enjoy loads of fresh fruits and vegetables. Grilled yellow squash is one of our favorites to make each year, and this recipe couldn’t be easier.

We love to serve it with sour cream pork chopschicken green beans and potatoesapple cider marinated pork loin, and turkey pot pie.

Grilled Yellow Squash

Yellow squash is one of those Summer vegetables that I always end up purchasing way more than I need. When that happens, I use the extra to make grilled yellow squash.

It’s an easy side dish, packed with fresh flavors, and it only takes a few minutes to cook. The longest part is waiting for it to marinate.

Medium squash are the best to use, because they’re firm and not too soft in the center. They soak up the flavor from the marinade well and caramelize easily over medium heat.

You can even cut the squash into long strips, but I’ve found that circles (medallions) are easier to work with and there are more to share!

Ingredients You’ll Need:

  • Fresh Lemon Juice.
  • White Wine Vinegar.
  • Fresh Herbs: Oregano, thyme, rosemary, etc.
  • Garlic.
  • Kosher Salt and Ground Black Pepper.
  • Olive Oil.
  • Yellow Squash.

Tips and Variations:

  • Squash: Make sure to cut the squash about ½-inch to ¾-inch thick so it cooks all the way through without being too soft.
  • Herbs: We love to use fresh herbs in the marinade. They have an amazing flavor and pair perfectly with the fresh squash. Dried herbs can be used, but if they stick to the squash they can burn as the squash cooks.
  • Marinade: The marinade is not meant to completely cover the squash. It’s only meant to lightly coat the squash. Make sure to toss the ingredients well, so the marinade is well distributed.
  • The Cut: Slice yellow squash into rounds, on the diagonal, into wedges, or into long planks. Make sure to keep it ½-inch to ¾-inch thick for the rounds, diagonal, and planks so the squash doesn’t get soggy.

How to Store Grilled Squash

Refrigerator: Grilled squash is best kept in an airtight container in the refrigerator and leftovers discarded after 3 days.

Freezer: The squash does not hold up well to freezing.

How do you cook squash so it’s not mushy?

Make sure not to slice the squash too thin, and don’t overcook the squash.

Watch it closely as it cooks, and remove it from the grill as soon as it begins to brown and caramelize.

Another option is to sprinkle the sliced squash with a little salt before placing it on the grill.

The salt helps to pull some of the moisture out of the squash, and it’s less likely to be mushy after it cooks.

Can you use zucchini instead of yellow squash?

Yes, you can use zucchini in place of the yellow squash in this grilled squash recipe.

Cooking zucchini is very similar to cooking yellow squash.

Either one works for this recipe or use a mixture of both.

What other flavors can you use to season grilled squash?

We love to use a marinade to season grilled squash to lessen the chance of burning the herbs and spices.

There are different marinade flavoring options you can use or skip the marinade and sprinkle seasonings over the squash instead.

​Here are some ideas:

  • Substitute the white wine vinegar with red wine vinegar.
  • Sprinkle the squash with garlic powder, onion powder, Italian seasoning or Italian herbs.
  • Add a little ranch seasoning.
  • A squeeze of lemon juice adds a brightness and extra flavor to the grilled squash.
