You can cook squash on the grill by slicing it, seasoning it, and cooking it over direct or indirect heat until it’s tender and has lovely char marks.
It’s one of the easiest and most delicious ways to enjoy summer and winter squash alike.
Whether you’re working with zucchini, yellow squash, butternut, or acorn squash, grilling brings out a natural sweetness you just can’t get from boiling or steaming.
In this post, we’ll walk through exactly how to cook squash on the grill, including prep tips, seasoning ideas, and timing for different varieties.
Let’s fire up that grill and get started.
How Do You Cook Squash on the Grill?
Cooking squash on the grill comes down to three simple steps: prep it, season it, and grill it.
The method varies slightly depending on whether you’re grilling tender summer squash or firmer winter squash.
But the core technique of cooking squash on the grill stays the same.
1. Choose the Right Squash
You can cook almost any squash on the grill.
Summer varieties like zucchini and yellow squash are quick and forgiving.
Winter varieties like butternut, acorn, and delicata take a bit longer but reward you with deep, caramelized flavor.
Pick squash that feels firm and heavy for its size.
2. Prep the Squash Properly
Wash your squash and pat it dry.
For summer squash, slice lengthwise into planks about half an inch thick.
For winter squash, cut it in half, scoop out the seeds, and slice into wedges or rings.
You can leave the skin on delicata and butternut since it softens nicely on the grill.
3. Season Generously
Brush each piece with olive oil so it doesn’t stick to the grates.
Then season with salt, pepper, and any herbs or spices you love.
Smoked paprika, garlic powder, and fresh thyme all work beautifully when you cook squash on the grill.
4. Preheat and Oil the Grates
Get your grill hot before the squash goes on.
Medium-high heat works well for summer squash, while medium heat is better for thicker winter squash.
Clean the grates and brush them with oil right before placing the squash down.
Grilling Times for Different Types of Squash
Timing matters when you cook squash on the grill, so here’s a quick guide:
1. Zucchini and Yellow Squash
Grill these for about 3 to 4 minutes per side.
They’re done when they have nice grill marks and feel tender but not mushy.
2. Butternut Squash
Grill wedges over medium heat for about 8 to 10 minutes per side.
They’re ready when a fork slides in easily.
3. Acorn Squash
Grill halves or rings for 10 to 12 minutes per side.
Brushing with a little maple syrup near the end adds amazing flavor.
4. Delicata Squash
These grill fast, around 5 to 6 minutes per side, and the skin becomes perfectly edible.
Tips for Perfectly Grilled Squash Every Time
A few small tricks make a big difference when you cook squash on the grill.
1. Don’t Overcrowd the Grill
Leave space between pieces so they roast instead of steam.
2. Use a Grill Basket for Small Pieces
If you’re grilling cubes or slices, a grill basket keeps everything from falling through the grates.
3. Flip Only Once
Let the squash develop char before flipping.
This gives you better texture and flavor when you cook squash on the grill.
4. Finish with a Little Something Extra
A squeeze of lemon, a drizzle of balsamic glaze, or a sprinkle of parmesan takes grilled squash to the next level.
5. Watch for Doneness, Not Just Time
Every grill runs differently, so trust your fork test over the clock.
So, How Do You Cook Squash on the Grill?
You cook squash on the grill by prepping it, seasoning it well, and grilling over the right heat until tender and charred.
