• Pesto

• Plain low fat Greek yogurt

• Flat leaf parsley

• Mozzarella cheese

• Parmesan cheese

How to Make Cheesy Pesto Chicken Spaghetti Squash

Start by roasting the spaghetti squash in the oven for 30-45 minutes depending on the size of it. Let the spaghetti squash cool for at least 15 minutes if not longer before trying to scrape it out. While the squash is cooling combine the pesto, Greek yogurt, spices and half the cheese together in a large bowl and stir them together until they’re combined.

Add the cooled spaghetti squash and shredded chicken into the bowl and stir together until everything is combined. Pour the mixture into an oven safe dish and top with the remaining cheese. Bake at 375° F. for about 20 minutes or until everything is heated through. Top with chopped parsley and extra dollops of pesto. 

How to Roast Spaghetti Squash

My go-to method for roasting spaghetti squash is simple and doesn’t require any fancy tools other than a sharp knife. 

1. Line a sheet pan with foil or parchment paper and spray it with cooking oil.
2. Cut the spaghetti squash in half lengthwise. You’ll want to use a sharp chef’s knife when you’re doing this. To make it easier, cut a small portion of the top of the squash off  so that the hard stem is removed. Often times this is where your knife will get stuck and you’ll be fighting to cut through it.
3. Scoop out the seeds using a spoon. Sprinkle the inside of the squash with a generous amount of kosher salt and fresh ground black pepper.
4. Place the squash cut side down onto the prepared sheet pan. Bake in the oven at 400° F. for 30-45 minutes. Small spaghetti squash may only need 30-35 minutes whereas a large one will like take between 40-45 minutes, possibly longer.
