How to grill squash on a gas grill?
You sure can grill squash on a gas grill, and it’s one of the easiest and tastiest ways to cook this versatile vegetable.
Whether you’re working with zucchini, yellow squash, butternut, or acorn squash, your gas grill can deliver that smoky, caramelized flavor you love without a ton of fuss.
In this post, we’ll walk through exactly how to grill squash on a gas grill, from choosing the right type to prepping, seasoning, and getting those perfect grill marks.
Let’s fire it up.
Why Grilling Squash on a Gas Grill Works So Well
Grilling squash on a gas grill works beautifully because the high, consistent heat caramelizes the natural sugars in the vegetable.
That caramelization is what gives grilled squash its slightly sweet, smoky taste and tender texture.
A gas grill is also incredibly convenient here because you can control the temperature precisely, which matters when you’re cooking something that can go from perfectly tender to mushy in minutes.
Plus, squash holds up well on grill grates, especially the firmer varieties, so you don’t have to worry about it falling apart.
1. It Works for Almost Every Type of Squash
From delicate zucchini to dense butternut, you can grill squash on a gas grill across a wide range of varieties.
Summer squash like zucchini and yellow squash cook quickly and soak up marinades beautifully.
Winter squash like butternut, acorn, and delicata need a bit more time but reward you with a rich, nutty flavor once grilled.
2. You Get Great Char Without the Guesswork
A gas grill gives you predictable, even heat, so you can grill squash without constantly babysitting the flame.
You can dial in a medium-high setting and know it’ll stay steady, which helps you avoid burning the outside before the inside is done.
That consistency is a big reason so many people prefer to grill squash on a gas grill rather than charcoal.
3. It’s Fast and Beginner-Friendly
Learning how to grill squash on a gas grill takes almost no time at all.
Once you’ve prepped your squash and heated the grill, most slices are done in under ten minutes.
That makes it a perfect weeknight side dish when you want something healthy and flavorful without a long cook time.
How to Prep Squash for a Gas Grill
Good grilling starts with good prep, and how you prep your squash depends on the type you’re using.
1. Wash and Dry Thoroughly
Give your squash a good rinse under cool water to remove any dirt or grit.
Then pat it completely dry with a clean towel.
Dry surfaces are key because excess moisture steams the squash instead of letting it char.
2. Cut It Into Even Pieces
For zucchini and yellow squash, slice them lengthwise into planks about half an inch thick.
For butternut or acorn squash, cut them into rounds or half-moon slices of similar thickness.
Even slices mean even cooking, which is essential when you grill squash on a gas grill.
3. Season and Oil Generously
Brush each piece with olive oil so it doesn’t stick to the grates.
Then season with salt, pepper, and whatever herbs or spices you enjoy.
Garlic powder, smoked paprika, and fresh thyme all pair wonderfully with grilled squash.
Step-by-Step: How to Grill Squash on a Gas Grill
Now for the fun part, actually getting that squash onto the grill.
1. Preheat Your Gas Grill Properly
Turn all your burners to medium-high and close the lid.
Let the grill heat for about ten to fifteen minutes so the grates get nice and hot.
A properly preheated grill is what gives you those beautiful sear marks when you grill squash.
2. Clean and Oil the Grates
Once hot, scrub the grates with a grill brush to remove any residue.
Then dip a folded paper towel in oil and, using tongs, rub it across the grates.
This extra layer of oil prevents sticking and makes flipping your squash much easier.
3. Place Squash Cut-Side Down
Lay your squash slices directly on the grates with the cut side facing down.
Close the lid and let them cook undisturbed for about four to five minutes.
Resist the urge to move them around, as leaving them alone is what builds those grill marks.
4. Flip Once and Finish Cooking
After the first side has nice char lines, flip each piece with tongs.
Cook for another three to four minutes until the squash is tender but not falling apart.
Thinner slices will finish faster, so keep an eye on them.
5. Move to Indirect Heat if Needed
If your squash is browning too quickly, move it to a cooler zone of the grill.
This lets the inside finish cooking without burning the outside.
It’s a simple trick that makes grilling squash on a gas grill much more forgiving.
6. Rest and Serve
Take the squash off the grill and let it rest on a platter for a couple of minutes.
Finish with a squeeze of lemon, a drizzle of balsamic, or a sprinkle of parmesan.
Then serve it warm alongside grilled chicken, steak, or a big summer salad.
Tips for Perfectly Grilled Squash Every Time
A few small habits make a big difference when you grill squash.
Keep slices uniform so they cook at the same rate.
Don’t overcrowd the grill, since crowding traps steam and prevents char.
And marinate firmer squash like butternut for at least thirty minutes to boost flavor and tenderness.
So, How to Grill Squash on a Gas Grill?
You grill squash on a gas grill by preheating to medium-high, oiling the grates, and cooking oiled, seasoned slices cut-side down for about four to five minutes per side.
It’s a quick, simple process that works for nearly every type of squash.
With steady heat and a little patience, your gas grill turns out tender, smoky, caramelized squash every single time.
Now go grab your squash and get grilling.
