01 - Preheat oven to 400°F. Halve the spaghetti squash lengthwise and remove the seeds. Place cut-side down on a baking sheet lined with parchment paper. Roast for 35–40 minutes until tender.
02 - Allow the roasted squash to cool slightly, then use a fork to scrape the flesh into spaghetti-like strands. Collect the strands in a large mixing bowl.
03 - In a separate bowl, toss the shredded chicken with buffalo sauce until thoroughly coated.
04 - Add the buffalo chicken mixture to the squash strands and mix gently. Transfer to a baking dish, sprinkle crumbled blue cheese over the top, and bake at 400°F for 10–12 minutes until heated through and cheese is lightly melted.
05 - Divide into portions and serve warm, garnished with additional blue cheese if desired.
