How to Grill Squash and Zucchini Perfectly Every Time
Knowing how to grill squash and zucchini comes down to a few key steps that make all the difference.
If you follow these, you’ll nail it every single time.
1. Pick the Right Squash and Zucchini
The foundation of great grilled squash and zucchini starts at the store or your garden.
Look for squash and zucchini that are firm, heavy for their size, and free of soft spots.
Medium-sized zucchini and yellow squash work best for grilling because they hold their shape without being seedy or watery.
If you’re planning to grill squash and zucchini, avoid the giant baseball-bat ones — they’re better for baking.
2. Slice Them Thick Enough to Handle the Heat
When you grill squash and zucchini, the thickness of your slices matters more than you’d think.
Cut them into planks about 1/4 to 1/2 inch thick, either lengthwise or into rounds.
Lengthwise planks are easier to flip and less likely to fall through the grates.
This is one of those small details that separates mediocre grilled squash and zucchini from truly excellent ones.
3. Season and Oil Before They Hit the Grill
To grill squash and zucchini that don’t stick or taste bland, toss your slices with olive oil first.
Then season generously with salt, pepper, garlic powder, or whatever herbs you love.
A little sprinkle of smoked paprika or Italian seasoning takes grilled squash and zucchini to the next level.
Let them sit for about ten minutes so the seasoning really sinks in.
4. Get Your Grill Hot and Clean
The secret to how to grill squash and zucchini without sticking is a hot, clean grill.
Preheat to medium-high, around 400 to 450°F, and scrape the grates well.
Brush the grates with a little oil right before placing your squash and zucchini down.
A properly heated grill gives you those beautiful char marks and keeps the veggies from turning to mush.
5. Cook Them Fast Over Direct Heat
When you grill squash and zucchini, timing is everything.
Lay the slices on the hot grates and leave them alone for 3 to 4 minutes.
Flip once and cook another 3 to 4 minutes until tender and lightly charred.
That’s really all there is to how to grill squash and zucchini — hot, fast, and simple.
Tips for Grilling Squash and Zucchini Without Mushiness
Nobody wants soggy, limp grilled squash and zucchini, so keep these tips in mind.
1. Don’t Overcrowd the Grill
If you pack too many slices onto the grates, your squash and zucchini will steam instead of sear.
Give each piece a little breathing room so the heat can do its job.
Grilling squash and zucchini in batches is way better than crowding them.
2. Salt Them Ahead of Time
Slicing and salting your squash and zucchini 15 minutes before grilling pulls out excess moisture.
Just pat them dry before oiling and seasoning again.
This trick ensures your grilled squash and zucchini stay firm and flavorful.
3. Skip the Marinade Soak
Unlike meat, squash and zucchini don’t need hours in a marinade.
A quick toss in oil and seasonings is plenty, because squash and zucchini absorb liquid fast and can get soggy.
Keep it simple and let the grill bring out their natural sweetness.
