  1. Preheat oven to 400 degrees F (200 degrees C). Grease a baking sheet.
  2. Place squash skin side down on prepared baking sheet. Bake until cooked through, about 1 hour. Remove from oven; cool for 10 minutes. Once squash is cool enough to handle, scrape flesh into string-like strands with a fork. Place in a bowl and set aside.
  3. Melt 1 tablespoon of butter in a large skillet over medium-high heat. Add onion; cook and stir until onion begins to turn translucent. Stir in kale and mushrooms; reduce heat to medium low.
  4. Stir in squash, remaining 2 tablespoons butter, garlic salt, Italian seasoning, and red pepper flakes; cook for 2 minutes. Remove from stove and place squash mixture in a large bowl.
  5. Stir olive oil and pesto into the squash mixture. Slowly add grated Parmesan cheese, stirring until evenly mixed.

I never thought spaghetti squash could truly replace spaghetti, but this recipe is one of the best things I've ever cooked! I love a good kick with my veggies, so the 1 tsp of red pepper flakes suited my taste buds perfectly, though those with a lower spice tolerance may want to cut it in half. In the future I might cut the butter and salt in half to see how it tastes, but this recipe is definitely spot-on!

Tried to make the recipe as is but had to adjust.. we used spinach as many other users commented. I cut the onion in half as it is not my favorite but there was still way too much onion.. had it in every bite and seemed like just as much squash as onion. Cut the pepper flakes in half and was still too spicy. Everything else was as written. Just had way too much pepper and onion for us.... leftovers went to waste. If we were too do it again I would omit the pepper flakes, cut way back on the onion possibly cook them until carmelized instead of translucent, add more mushrooms and spinach as wasn't near enough.

I followed the recipe as is and it turned out excellent!!! The only thing I may change next time is adding some warm toasted pine nuts to add a crunch, but either way this is a 5 star recipe.

This was so good. I've never had spaghetti squash before, let alone made it. And this was so easy. I didn't have any kale so I used spinach. I also didn't use all of the butter. But I will absolutely be making this again and again.

I am a VERY finicky eater and this was my first time trying to Spaghetti Squash and I'm glad I picked this recipe to make my "virgin" voyage on. I used spinach instead of kale, and olive oil instead of butter...I added bite size chicken that I pre-seasoned before cooking -- mainly because I thought if I didn't like the squash I could pick the chicken out and eat it. But, this recipe was AWESOME!!! I may add a bit more spinach the next time I make it, just for my own personal taste. I love my food spicy so the amount of red pepper flakes was just right...however I would caution that it maybe too spicy for young kids but AGAIN this recipe was FANTASTIC!!!! I've attached a picture of how mine came out.

We are spaghetti squash lovers so this was right up our alley. Had to leave out mushrooms due to an allergy but we don't miss them anymore. We did the squash in the slow cooker on high for 5 hours. It could have used less time but we didn't check it along the way. Otherwise the recipe was followed to a tee and it was amazing. Thx Shyla!

This was my first time cooking with spaghetti squash. I loved this dish! I cooked a few strips of bacon and then sauteed fresh garlic and onion in the bacon grease, and substituted spinach for the kale. Otherwise used recipe as specified. VERY tasty and filling.

Very good! I added some chunks of pork roast, which complimented it really well.
