In this post, we’ll walk through exactly how to make squash on the grill, from choosing the right type to nailing that perfect char.
 
Let’s fire it up.
 

How to Make Squash on the Grill

Making squash on the grill starts with picking the right squash and prepping it properly.
 
The good news is that almost any squash can be grilled, but the method changes a bit depending on whether it’s a summer squash or a winter squash.
 
Summer squash like zucchini and yellow squash are tender and quick-cooking.
 
Winter squash like butternut, acorn, and kabocha are denser and need a little more time and care.
 
Here’s how to make squash on the grill so it comes out tender, smoky, and perfectly caramelized every single time.
 

1. Choose the Right Squash for Grilling

When you make squash on the grill, the type you pick matters.
 
Zucchini and yellow squash are the easiest because they cook fast and hold their shape well.
 
Delicata squash is another winner because its skin is thin and edible, so you don’t even have to peel it.
 
Butternut and acorn squash work great too, but you’ll want to cut them into thick slices or planks so they don’t fall apart on the grates.
 
The key is to avoid very watery squash or ones that are past their prime.
 
Firm, fresh squash grills best.
 

2. Prep the Squash Properly

Before you make squash on the grill, give it a good wash and dry it off.
 
For summer squash, slice it lengthwise into planks about half an inch thick.
 
For winter squash, peel it if the skin is tough, scoop out the seeds, and cut it into slices or wedges that are at least half an inch thick.
 
If you’re grilling smaller squash like acorn, you can cut it into rings or half-moons.
 
The goal is to keep the pieces big enough that they won’t slip through the grates.
 

3. Season and Oil the Squash

To make squash on the grill really shine, toss your pieces with a little olive oil, salt, and pepper.
 
The oil helps prevent sticking and encourages that beautiful grill mark caramelization.
 
You can also add garlic powder, smoked paprika, or fresh herbs like thyme and rosemary.
 
If you want a little heat, a pinch of cayenne or chili flakes works wonders.
 
Just don’t overdo the oil, or you’ll get flare-ups on the grill.
 

4. Preheat the Grill and Manage the Heat

When you make squash on the grill, a hot, clean grill is your best friend.
 
Preheat your grill to medium-high heat, around 400°F to 450°F.
 
Clean the grates well and brush them with a little oil to prevent sticking.
 
If you’re using a gas grill, keep one side on high and one side on low so you can move pieces around if they start to char too fast.
 
For a charcoal grill, spread the coals evenly for consistent heat.
 

5. Grill the Squash and Flip Once

Place your squash pieces directly on the grill grates.
 
For summer squash, grill for about 3 to 4 minutes per side.
 
For winter squash, it can take 5 to 7 minutes per side, depending on the thickness.
 
Don’t move the squash around too much.
 
Let it sit and get those lovely grill marks.
 
Flip it once with tongs, and grill until the flesh is tender and slightly charred at the edges.
 

Tips and Variations for Grilled Squash

Once you know how to make squash on the grill, you can start playing around with flavors and techniques.
 
Here are some of my favorite tips and variations to keep things interesting.
 

1. Use a Grill Basket for Small Pieces

If you’re grilling cubed squash or smaller chunks, a grill basket is a lifesaver.
 
It keeps everything from falling through the grates and makes tossing easier.
 
Just spread the pieces in a single layer and shake the basket every few minutes.
 

2. Add a Marinade or Glaze

You can make squash on the grill even tastier by brushing it with a marinade or glaze.
 
Balsamic vinegar and honey is a classic combo.
 
So is a mix of soy sauce, ginger, and sesame oil.
 
Just brush it on during the last few minutes of grilling so the sugars don’t burn.
 

3. Grill Whole or Halved Small Squash

Small squash like acorn or delicata can be grilled whole or halved.
 
Just cut them in half, scoop out the seeds, and brush the cut sides with oil.
 
Place them cut-side down first for nice char marks, then flip and finish cooking with the lid closed.
 

4. Finish with Fresh Herbs and Citrus

After you make squash on the grill, a squeeze of lemon or lime juice brightens everything up.
 
Toss on some chopped parsley, cilantro, or basil.
 
A sprinkle of feta or parmesan doesn’t hurt either.
 

5. Don’t Overcook It

The biggest mistake when you make squash on the grill is cooking it too long.
 
Squash should be tender but not mushy.
 
Start checking a minute or two before you think it’s done.
 
It’ll continue to soften slightly after you take it off the heat.
 

So, How to Make Squash on the Grill?

You can make squash on the grill by choosing firm squash, cutting it into thick pieces, oiling and seasoning it, and grilling over medium-high heat until tender and charred.
 
It’s a simple process that works with almost any squash variety.
 
Whether you go with zucchini, butternut, or acorn, the grill brings out a smoky depth that’s hard to beat.
 
So next time you’re firing up the grill, throw on some squash.
 
You’ll be glad you did.
