My wife and I love spaghetti squash and even the kids enjoy it. It’s a winter staple in our house and a healthy addition to any meal from meatloaf to chicken Parm. But we didn’t often cook it in the summer because we didn’t want to use the oven on a hot day.

Then one day I tried cooking spaghetti squash on the grill and it was a huge hit.

Grilled spaghetti squash has become one of our favorite side dishes for any barbecue and if you follow the simple instructions below you’re going to love it too.

How To Grill Spaghetti Squash

This recipe is so simple and only requires a handful of ingredients that you probably already have in your kitchen.


  • Spaghetti squash
  • Olive oil
  • Kosher salt
  • Black pepper
  • Granulated garlic
  • Parmesan cheese (optional)

Step by Step

You’ll want to preheat your grill to medium-high. You can make bbq spaghetti squash on a charcoal grill, a pellet smoker, or a propane grill. Whatever type of grill you use, make sure it’s set up for indirect grilling.

Cut the spaghetti squash in half lengthwise. Make sure you have a good knife and use caution to prevent cutting yourself.

Brush olive oil all over the flesh of each half and the sprinkle on the seasonings.

Add the spaghetti squash, close the lid, and let it cook until fork tender. A smallish spaghetti squash will take about 30 minutes and a larger one will take 45 to 60 minutes.

Remove from the grill when you can easily penetrate the flesh with a fork and it comes away looking like spaghetti. If you undercook it the fibers won’t easily come apart and it will be tough to eat, but if you overcook it the squash will turn to mush.

Once the squash is off the grill, use a fork to shred it and add to a serving dish. Sprinkle with Parmesan cheese and some parsley for garnish and serve.


I like to keep the seasoning very basic and let the flavor of the squash shine. Of course you can add a sprinkle of smoked paprika or your favorite BBQ rub if you want to add some additional flavor.

You can also swap out the olive oil and use butter instead. It will be a little less healthy but the flavor will be absolutely bangin!

Add some diced tomatoes or a spoon full of marinara sauce for a different take on grilled spaghetti squash.
