My daughter in law gave us a spaghetti squash that she received as part of her her grocery pick up as a substitute for a cantaloupe – hilarious, right? Anyway, we decided to give it a try on the grill and loved it. It seriously doesn’t get any easier than this!

How to Grill Spaghetti Squash:

Grilling spaghetti squash with butter

  • Cut spaghetti squash in half lengthwise. You will need a strong arm and a big knife. They are not easy to cut. 
  • Scoop out the seeds and discard. 
  • Place 2 tablespoons of butter into each half and sprinkle with garlic, salt and pepper. 
  • Place spaghetti squash cut side up onto indirect heat of a 300° fire. We used hickory for smoke flavor, pecan would be great also. 

Cooking spaghetti squash on the grill

  • Cook with the lid closed about 30- 35 minutes. Test squash by piercing with a fork for tenderness. Squash will easily shred when cooked through. 
  • I like spaghetti squash to maintain a bit of texture or bite like pasta better than if it’s cooked longer and softer. 

Grilled Spaghetti Squash on a sheet pan

  • Remove from grill to a sheet pan.

Grilled Spaghetti Squash - shredded

  • Shred with a fork. If you are having a casual family dinner, you can serve it right from the sheet pan. If you are entertaining, just scoop out the shredded squash to a serving dish.

Parmesan and herb Spaghetti Squash

  • Top with parmesan cheese and fresh herbs if desired. 
  • You can also add in diced tomatoes or top with your favorite marinara sauce or Alfredo sauce.

What is Spaghetti Squash?

I am a huge fan of summer squash, especially when it’s Fried Squash!  Spaghetti squash is a winter squash. It has a mild almost sweet flavor, different from other winter squash like acorn or butternut. When it’s cooked it becomes stringy when you shred it. A lot like spaghetti and while it’s a great substitute it is not pasta. The texture is a lot more similar if you do not over cook it. 

I have roasted spaghetti squash in the oven and I’ve had it in a casserole but it is my favorite on the grill. Most people seem to cook it cut side down to get the grill marks but after it is shredded, those are not noticeable. I loved how the garlic butter cooked down into the squash. It was very flavorful and delicious.
