Generously grease an 8×8 round or square casserole dish with cooking spray and set aside. Preheat the oven to 400 degrees F.

Cut the spaghetti squash in half and remove the seeds. Using a pastry brush, brush the olive oil all over the inside of the spaghetti squash halves. Season generously with salt and pepper to taste.

Place cut side down on parchment lined or a silicone lined baking sheet. Bake for 30-35 minutes until a knife inserted slides through the squash easily.

Once cooked, remove from the oven, flip over and allow to cool for 10-15 minutes. Once cooled, use a fork and scrape the spaghetti from the shell.

Place the spaghetti noodles into the prepared casserole dish and spread out evenly. Set aside.

In a small saucepan, melt the butter over medium-low heat. Stir in the chopped garlic, 2/3 cup of the half and half, parsley, salt, pepper and shredded Parmesan.

Stir constantly until all of the cheese is melted and the sauce has thickened.

Remove from the heat and stir in remaining 1/3 cup of half and half until completely combined. Pour the sauce over the spaghetti noodles in the prepared pan.

Sprinkle the shredded mozzarella cheese evenly over the top of the spaghetti noodles and sauce. Bake at 375 degrees for 15 minutes until heated through.

Switch the oven to broil mode and broil 2-3 minutes until cheese is browned and bubbly.

Remove from oven and allow to stand for 5 minutes before serving. Enjoy!
