Grilled squash

Need a quick and easy summer side dish? Or got a load of yellow summer squash? Try this perfect grilled squash! It’s simple but full of big flavor, seasoned with Italian herbs like basil and oregano. Even better: it takes only 5 minutes to grill! It’s one of those sides that screams summer: you can almost smell the charcoal and hear the buzz of the lawnmower. Along with grilled zucchini, this has become a favorite for Alex and me because it’s so quick: and hard to mess up.

Ingredients for grilled squash

When we say grilled squash, we’re talking summer squash. Yes, that large yellow squash that it seems everyone has more than enough of! interestingly, there aren’t tons of recipes that use the summer variety: you won’t find much summer squash soup or risotto like you do with winter squash. So making grilled squash is one of the best ways to use it (outside of roasted)! Here’s what you need:

  • Yellow summer squash (or a mix of squash and zucchini for variation in color!)
  • Olive oil
  • Salt and pepper
  • Spices: Dried basil, dried oregano, onion powder, garlic powder

How to cut squash for grilling

There are a few different ways to cut summer squash for the grill. Here’s a little breakdown:

  • Rounds. You can slice the squash into 1/2-inch thick rounds. But the way we like to do it is…
  • On the bias (diagonal). It looks similar to rounds, but if you cut on the bias (diagonally), you get larger, most interesting shapes.
  • Planks. You also can cut the squash width-wise into long planks. (We did this for our grilled zucchini.)

How to grill squash

You can grill squash right on the grill grates: no grill basket or foil necessary! It’s fast and easy: just cook them until they’re charred and tender. Here are the basic steps (or jump to the recipe):

  • Preheat a grill to medium high heat. That’s about 375 to 450 degrees.
  • Cut the squash on the bias (diagonally). Make the pieces about 3/4-inch thick.
  • Toss with olive oil and seasonings. The blend of Italian spices in the recipe below is perfect.
  • Grill on the grates for 4 to 6 minutes. Cook until charred and tender, turning once.

Variations on seasoning for grilled squash

Yellow summer squash and zucchini work well with Italian and Mediterranean seasonings, but there’s no reason not to change it up. Here are a few other seasonings that would work well.

Important: Keep in mind many of these blends have salt included. Use ¼ teaspoon of the salt below, then sprinkle with the seasoning.

  1. I tries this Squash tonight and was very pleasantly surprised – it was the first time I’ve been able to cook Squash (besides sautéing with garlic and onions until its cooked to death) in a way I actually liked. I learned I should have mixed the spices in a separate bowl before tossing as some spices clumped in excess on a few pieces, but I know I was just cutting some corners to speed up the process and mixing spices separately should fix the issue of getting too much of one spice on different pieces. Fantastic recipe! Will definitely make these again!
