You can grill yellow squash easily, and it turns out tender, sweet, and slightly smoky every single time.
If you’ve been wondering how to grill yellow squash without it turning mushy or sticking to the grates, you’re in the right place.
Grilling yellow squash is one of the simplest ways to enjoy this summer vegetable at its best.
The high heat caramelizes its natural sugars and gives it a flavor that boiling or steaming just can’t match.
In this post, we’ll walk through how to grill yellow squash step by step, plus a few tips that make the whole process foolproof.
Let’s fire up that grill.
How to Grill Yellow Squash Perfectly Every Time
Learning how to grill yellow squash comes down to a few key moves.
Get these right and you’ll have a side dish that disappears before anything else on the plate.
1. Pick the Right Squash
Small to medium yellow squash, about 6 to 8 inches long, grill best.
Bigger squash tend to have tough skins and watery, seedy centers that fall apart on the grill.
Look for firm squash with glossy skin and no soft spots.
If you’re growing your own, pick them young for the sweetest flavor.
2. Slice It Evenly
Cut your yellow squash into uniform planks or rounds about half an inch thick.
Even slices cook at the same rate, so nothing turns to mush while the rest stays raw.
For long slices, cut the squash lengthwise into slabs.
This gives you more surface area for those beautiful grill marks.
3. Salt and Rest
Sprinkle your sliced yellow squash with salt and let it sit for about 15 minutes.
This draws out excess moisture so the squash grills instead of steaming.
Pat the slices dry with a paper towel before they hit the grill.
That one step makes a huge difference in texture.
4. Oil and Season
Brush both sides of each slice lightly with olive oil.
Oil keeps the squash from sticking and helps it brown nicely.
Then season with black pepper, garlic powder, or whatever herbs you love.
Keep it simple so the natural sweetness of the squash shines through.
Best Way to Grill Yellow Squash on the Barbecue
Once your squash is prepped, the actual grilling takes just minutes.
Here’s how to grill yellow squash on a gas or charcoal grill without any guesswork.
1. Preheat to Medium-High Heat
Heat your grill to around 400°F and clean the grates well.
A hot, clean grill is the secret to squash that releases easily instead of tearing.
Wipe the grates with a little oil right before adding the squash.
2. Grill 3 to 4 Minutes Per Side
Lay the slices flat and leave them alone for 3 to 4 minutes.
Flip once and grill another 3 to 4 minutes until tender and charred at the edges.
Resist the urge to keep flipping, since that’s how squash breaks apart.
3. Watch for Doneness
Your yellow squash is ready when it’s fork-tender with crisp, browned edges.
If it bends easily when you lift it with tongs, it’s done.
Pull it off the heat right away so it doesn’t overcook.
4. Try a Grill Basket for Small Pieces
Grilling yellow squash in rounds or chunks can be tricky on wide grates.
A grill basket keeps everything contained and lets you toss the pieces as they cook.
This is also a great method when you’re grilling yellow squash and zucchini together.
Tips and Variations for Grilled Yellow Squash
Want to take your grilled yellow squash up a notch?
These little extras make a big difference.
1. Add a Marinade
A simple mix of olive oil, lemon juice, garlic, and herbs adds tons of flavor.
Marinate your sliced yellow squash for 30 minutes before grilling.
Just don’t go longer than an hour, or the acid will make the texture soft.
2. Finish with Fresh Toppings
A squeeze of lemon, a sprinkle of parmesan, or torn basil takes it over the top.
Crumbled feta and a drizzle of balsamic glaze work beautifully too.
Add these after grilling so they stay fresh.
3. Avoid These Common Mistakes
Don’t slice too thin, don’t skip the salt-and-rest step, and don’t overcrowd the grill.
Crowding steams the squash instead of charring it.
And always oil the squash, not just the grates.
4. Serve It Right Away
Grilled yellow squash tastes best hot off the grill.
If you need to hold it, keep it warm in a covered dish for no more than 20 minutes.
Leftovers are great chopped into salads or tossed with pasta the next day.
