Preheat oven to 400 degrees.

Using a fork, place small holes into the spaghetti squash so it can breath while baking.

Place the spaghetti squash into a large casserole dish and bake for 50 minutes.

Allow the spaghetti squash to cool for 5-10 minutes.

While you are letting the spaghetti squash cool, prepare the buffalo chicken by place the cream cheese and the hot sauce in a large saucepan. Allow the cream cheese to completely melt.

Add in the ranch dressing and chicken breasts.

Cut the spaghetti squash length-wise in half and scoop out the insides. Place the buffalo chicken on top of the spaghetti squash and sprinkle with the cheddar cheese.

Bake for another 5-10 minutes, or until the cheese has completely melted.
