You can cook acorn squash on the grill, and it turns out tender, smoky, and slightly caramelized every single time.
If you’ve been wondering how to cook acorn squash on the grill without drying it out or burning the edges, you’re in the right place.
Grilling acorn squash is actually one of the easiest ways to prepare this fall favorite because the high heat brings out its natural sweetness.
In this post, we’ll walk through exactly how to grill acorn squash, from choosing the right squash to slicing, seasoning, and getting those beautiful grill marks.
Let’s fire up the grill and get cooking.
Why You Should Cook Acorn Squash on the Grill
Cooking acorn squash on the grill is a game changer for anyone who loves roasted squash but wants something a little more exciting.
Grilling gives acorn squash a smoky depth that you just can’t get from an oven.
Here’s why it works so well.
1. The Grill Adds Smoky Flavor
When you cook acorn squash on the grill, the natural sugars in the flesh caramelize against the hot grates.
That caramelization creates a rich, nutty flavor that pairs perfectly with the squash’s mild, earthy taste.
Plus, if you’re using a charcoal grill, you get an extra layer of smokiness that makes every bite taste like fall.
2. Grilling Keeps the Inside Tender
A lot of people worry that grilling acorn squash will dry it out.
But when you cook acorn squash on the grill with the right technique, the inside stays soft and creamy while the outside gets nicely charred.
The key is to use indirect heat or a covered grill so the squash steams slightly as it cooks.
3. It’s Faster Than Roasting
Roasting acorn squash in the oven can take up to an hour.
When you cook acorn squash on the grill, you can have it ready in about 30 to 40 minutes, depending on the size of your slices.
That makes it a great option for weeknight dinners when you still want something that tastes special.
How to Cook Acorn Squash on the Grill Step by Step
Now that you know why grilling acorn squash is such a good idea, let’s get into the how.
Follow these steps to cook acorn squash on the grill like a pro.
1. Choose and Prep Your Acorn Squash
Start with a firm, heavy acorn squash that feels solid for its size.
Look for one with dark green skin and no soft spots.
Wash it thoroughly, then cut it in half lengthwise.
Scoop out the seeds and stringy bits with a spoon.
You can leave the skin on because it helps the squash hold its shape on the grill.
2. Slice It into Wedges or Rings
You can cook acorn squash on the grill as halves, wedges, or rings.
Wedges are the easiest because they cook evenly and are simple to flip.
Cut each half into three or four wedges, depending on how thick you want them.
Aim for pieces that are about one inch thick at the widest part.
3. Season the Squash Generously
Before you cook acorn squash on the grill, brush each piece with olive oil.
Then season with salt, black pepper, and any other spices you like.
Brown sugar, cinnamon, or smoked paprika all work beautifully.
For a savory twist, try garlic powder, thyme, or a little chili powder.
4. Preheat the Grill to Medium Heat
Set your grill to medium heat, around 375°F to 400°F.
If you’re using a gas grill, turn on half the burners and leave the other half off for indirect cooking.
For charcoal, pile the coals on one side and cook the squash on the other.
Clean the grates and brush them with oil so the squash doesn’t stick.
5. Grill the Squash with the Lid Closed
Place the squash pieces directly on the hot grates, cut side down.
Close the lid and let them cook for about 8 to 10 minutes.
Then flip them over and move them to the cooler side of the grill if you’re using indirect heat.
Close the lid again and cook for another 15 to 20 minutes.
The squash is done when a fork slides in easily and the edges are nicely charred.
6. Finish with a Glaze or Butter
During the last few minutes of grilling, brush the squash with melted butter, maple syrup, or a balsamic glaze.
This adds shine and extra flavor.
When you cook acorn squash on the grill, this final step really takes it over the top.
Tips for Perfect Grilled Acorn Squash
These little tricks will help you cook acorn squash on the grill with great results every time.
1. Don’t Crowd the Grill
Leave space between each piece so the heat circulates evenly.
If you crowd the grill, the squash will steam instead of roast, and you won’t get those lovely char marks.
2. Use a Thermometer if You’re Unsure
The internal temperature of perfectly cooked acorn squash should be around 190°F.
If you’re not sure whether it’s done, a quick read with a meat thermometer takes the guesswork out of it.
3. Keep the Skin On
The skin helps the squash hold its shape on the grill.
Once it’s cooked, the skin becomes soft enough to eat, or you can scoop the flesh out easily.
4. Experiment with Wood Chips
If you want even more smoky flavor when you cook acorn squash on the grill, add soaked wood chips like hickory or applewood.
Just toss a handful onto the coals or in a smoker box on a gas grill.
So, How Do You Cook Acorn Squash on the Grill?
You cook acorn squash on the grill by slicing it into wedges, seasoning it with oil and spices, and grilling it over medium heat with the lid closed until tender and caramelized.
It’s a simple process that delivers big flavor with very little effort.
Whether you’re serving it as a side dish for a cookout or making it the star of a fall meal, grilled acorn squash is always a crowd-pleaser.
So the next time you’re planning dinner, skip the oven and cook acorn squash on the grill instead.
Your taste buds will thank you.
