Once you try these spaghetti squash recipes on the grill, you’ll never go back to the oven. Grilling adds so much natural flavor and results in the most amazing texture. Tender, sweet and dotted with rich roasted bits of the caramelized squash.

How To Make Spaghetti Squash

I usually post a snap of our dinner on Instagram and I saw several comments from followers asking how I grilled my spaghetti squash. I thought a simple post with a few different spaghetti squash recipes would really help out!

Simply start by cutting the spaghetti squash in half lengthwise. I say simply as a bit of a joke, because if you’ve ever had to cut a spaghetti squash in half, you know it can be a pain in the butt. Make sure you’ve got a great, sharp chef’s knife (my husband gave me this one for Mother’s Day AND it’s really affordable). Trim off about an inch from each end of the squash before slicing lengthwise. Use a big spoon to scrape the inside seeds and strings out and you’re ready to go!

Follow the recipe below for perfectly grilled spaghetti squash (my favorite grill for this is a pellet grill). Once you’ve got the cooking method down, you can start adding in some of these fun ideas for the perfect side dish or a complete meal!

  1. I just cooked a spaghetti squash with my Camp Chef Woodwind pellet grill and all I can say is WOW!! We eat a lot of spaghetti squash with the low carb diet. The flavor was the best I’ve ever had. Being from Oklahoma, where today was in the 90s, I loved not heating the house up with my oven. My new favorite way of cooking a spaghetti squash!
