How Long Do You Grill Yellow Squash

You can grill yellow squash for about 4 to 6 minutes per side over medium-high heat.
 
That puts the total grilling time somewhere between 8 and 12 minutes, depending on how thick you slice it.
 
If you’ve been wondering how long do you grill yellow squash so it comes out tender but not mushy, the answer really comes down to thickness, heat, and a little bit of patience.
 
Yellow squash grills fast because it’s tender and full of water, so the window between perfectly charred and totally soggy is pretty narrow.
 
In this post, we’ll walk through exactly how long to grill yellow squash, how to prep it, and the little tricks that keep it firm and flavorful every single time.
 
Let’s get grilling.
 

How Long Do You Grill Yellow Squash?

How long you grill yellow squash depends mostly on how you cut it, but here’s a good starting point:

1. Sliced Rounds or Spears: 4 to 6 Minutes Per Side

When you grill yellow squash in rounds or spears, plan on 4 to 6 minutes per side over medium-high heat.
 
That gives you a total grilling time of about 8 to 12 minutes, which is the sweet spot for most people.
 
Rounds that are about half an inch thick tend to cook a little faster, so keep an eye on them after the first 4 minutes.
 
Spears are a bit more forgiving because they hold their shape, but they still need the same rough timing.
 

2. Lengthwise Planks: 5 to 7 Minutes Per Side

If you slice your yellow squash lengthwise into planks, you’ll grill yellow squash for about 5 to 7 minutes per side.
 
Planks are thicker and have more surface area, so they take slightly longer to soften all the way through.
 
The upside is that planks are way easier to flip and they won’t slip through your grill grates.
 

3. Whole or Halved Squash: 8 to 10 Minutes Per Side

Grilling yellow squash whole or halved takes the longest, usually 8 to 10 minutes per side.
 
Smaller squash work best for this method because larger ones stay raw in the middle.
 
Half them lengthwise, scoop out the seeds if they’re big, and you’ve got a sturdy little boat that grills beautifully.
 

How to Prep Yellow Squash for Grilling

Good grilling starts before the squash ever hits the grate, so here’s how to get it ready:

1. Slice It Evenly

Cut your yellow squash into even pieces so everything finishes cooking at the same time.
 
Aim for rounds about half an inch thick, or planks about a quarter inch thick.
 
If some pieces are thick and others are paper thin, you’ll end up with a mix of burnt and raw squash on the same platter.
 

2. Salt It and Let It Sit

Sprinkle your sliced yellow squash with salt and let it sit for about 15 minutes.
 
The salt pulls out excess moisture, which is the number one reason grilled squash turns out soggy.
 
Pat the slices dry with a paper towel before they go on the grill.
 

3. Brush With Oil, Not Drizzle

Brush each piece lightly with olive oil instead of pouring oil over the whole bowl.
 
A thin, even coat helps the squash char without causing flare-ups.
 
You can also add your seasonings right after oiling so they stick to the surface.
 

Tips for Perfectly Grilled Yellow Squash

A few small moves make a big difference when you grill yellow squash:

1. Preheat Your Grill Properly

Give your grill a good 10 to 15 minutes to heat up before the squash goes on.
 
You want medium-high heat, around 400 to 450°F.
 
A hot, clean grate is what gives you those gorgeous grill marks instead of a sticky mess.
 

2. Don’t Flip Too Early

Resist the urge to poke and flip your yellow squash every couple of minutes.
 
Let it sit for the full 4 to 6 minutes on the first side so it can develop a nice char.
 
If it sticks when you try to flip it, it’s not ready yet, so give it another minute.
 

3. Pull It Off While It’s Still Firm

The biggest mistake people make is grilling yellow squash until it’s soft and limp.
 
Take it off when it’s tender but still holds its shape, because it keeps cooking for a minute or two after it leaves the heat.
 
That way you get squash with a little bite instead of mush.
 

4. Finish With a Squeeze of Lemon

A squeeze of fresh lemon juice right after grilling brightens up the flavor instantly.
 
A sprinkle of parmesan or fresh herbs doesn’t hurt either.
 
Serve it hot off the grill for the best texture and taste.
 

So, How Long Do You Grill Yellow Squash?

You grill yellow squash for about 4 to 6 minutes per side, or 8 to 12 minutes total, over medium-high heat.
 
Thicker cuts like planks and halves need a little more time, while thin rounds cook fast.
 
Salt your squash first, oil it lightly, and pull it off the grill while it’s still firm for the best results.
 
Now that you know exactly how long to grill yellow squash, fire up that grill and enjoy.
