In this post, we’ll walk through how to grill zucchini and squash perfectly, from choosing the right squash to nailing the seasonings and avoiding common mistakes.
 
Let’s fire up the grill and get started.
 

How to Grill Zucchini and Squash Perfectly Every Time

Grilling zucchini and squash comes down to a few key techniques that keep them tender on the inside and beautifully charred on the outside.
 
Follow these steps and you’ll know exactly how to grill zucchini and squash like a pro.
 

1. Pick the Right Zucchini and Squash

The best zucchini and squash for grilling are firm, young, and relatively small.
 
Look for zucchini that are about six to eight inches long and squash that feel heavy for their size.
 
Smaller zucchini and squash have fewer seeds and firmer flesh, which means they hold up beautifully on the grill.
 
If your zucchini or squash feels soft or spongy, it’ll likely turn mushy once it hits the grates.
 
So grab the firm ones, and you’re already halfway to grilled zucchini and squash perfection.
 

2. Slice Them Thick and Uniform

How you cut your zucchini and squash matters just as much as how you grill them.
 
Slice zucchini and squash into planks about half an inch thick, or cut them into thick rounds.
 
Thin slices tend to fall apart or burn before they’re cooked through.
 
Uniform slices also cook at the same rate, so every piece of grilled zucchini and squash comes off the grill at the same time.
 
For longer squash varieties, cut them lengthwise into spears so they don’t slip through the grates.
 

3. Season and Oil Them Well

Zucchini and squash need a little help before they hit the grill.
 
Brush each slice with olive oil on both sides so they don’t stick and so they pick up those gorgeous grill marks.
 
Then season generously with salt, black pepper, garlic powder, or your favorite herb blend.
 
You can also toss grilled zucchini and squash in a simple marinade of olive oil, lemon juice, and herbs for extra flavor.
 
Just don’t skip the oil, because dry zucchini and squash on the grill is a recipe for sticking and tearing.
 

Best Ways to Grill Zucchini and Squash

There’s more than one way to grill zucchini and squash, and each method gives you a slightly different result.
 
Here are the three best approaches depending on your setup and your mood.
 

1. Direct Grilling on the Grates

Direct grilling is the classic way to cook zucchini and squash on the grill.
 
Preheat your grill to medium-high heat and clean the grates well.
 
Place the oiled and seasoned zucchini and squash slices directly on the grates.
 
Grill for about three to four minutes per side until you see nice char marks and the flesh softens.
 
This method gives you that smoky grilled zucchini and squash flavor everyone loves.
 

2. Grilling in a Basket or Foil Packet

If you’re worried about slices falling through the grates, a grill basket is your best friend.
 
Toss zucchini and squash pieces into the basket and grill over medium heat, stirring occasionally.
 
For a foil packet version, wrap zucchini and squash with oil, garlic, and herbs, then grill for about ten to twelve minutes.
 
This is a foolproof way to grill zucchini and squash without losing a single piece.
 

3. Skewers for Fun, Bite-Sized Pieces

Skewers are perfect when you want grilled zucchini and squash as a side or party appetizer.
 
Thread thick rounds of zucchini and squash onto soaked wooden or metal skewers.
 
Brush with oil and seasonings, then grill for about eight to ten minutes, turning often.
 
You can even add cherry tomatoes, onions, or bell peppers to make colorful veggie skewers.
 

Common Mistakes to Avoid When Grilling Zucchini and Squash

Even simple grilled zucchini and squash can go wrong if you skip a step or two.
 
Here are the mistakes to watch out for.
 

1. Slicing Them Too Thin

Thin slices of zucchini and squash dry out and burn fast on a hot grill.
 
Stick to half-inch thickness so they stay juicy and hold their shape.
 

2. Skipping the Oil

Oil isn’t optional when you grill zucchini and squash.
 
Without it, they stick to the grates, tear apart, and lose that nice golden char.
 

3. Overcooking Them

Zucchini and squash cook quickly, so keep an eye on them.
 
Pull them off when they’re tender but still hold their shape, not when they’ve turned to mush.
 

4. Not Preheating the Grill

A properly preheated grill gives you those beautiful sear marks and prevents sticking.
 
Give your grill at least ten to fifteen minutes to heat up before adding zucchini and squash.
 

So, How Do You Grill Zucchini and Squash?

Grilling zucchini and squash is simple when you pick firm vegetables, slice them thick, oil and season them well, and cook them over medium-high heat.
 
Whether you use direct grates, a grill basket, or skewers, grilled zucchini and squash come out tender, smoky, and full of flavor.
 
Avoid thin slices, skipped oil, and overcooking, and you’ll have a side dish that disappears fast at every barbecue.
 
Now that you know how to grill zucchini and squash, it’s time to fire up the grill and enjoy.
