01
Preheat your oven to 375° F. Line a baking sheet with parchment paper. With a sharp knife, slice the spaghetti squash lengthwise. Remove the seeds with a spoon.
02
Place on the prepared baking sheet with the cut side down. Bake for 40 minutes, until tender.
03
Allow the squash to cool slightly. Use a fork to scoop out the noodles. In a large bowl, combine the chicken, celery, tomato, hot sauce, ranch dressing, melted butter, and half of the cheddar cheese.
04
Toss with the spaghetti squash noodles. Transfer to a 9 x 9 casserole dish and top with the remaining cheddar and blue cheese. Taste and season with salt and pepper if desired.
05
Bake for 10 minutes, until the chicken is heated through and the cheese is melted.
