Instructions

To cook the spaghetti squash:

1. To cook in the oven, preheat the oven to 400 degrees. Cut the squash in half lengthwise and scoop out the seeds with a spoon. Discard the seeds. Drizzle with olive oil and place face down on a baking sheet. Bake for 1 hour or until squash is fork tender.
2. Alternately, make Instant Pot Spaghetti Squash.
3. Once squash is cooked, shred the squash into long spaghetti-like strands by using a fork to scrape the squash widthwise.

For the filling: 

1. Add the cooked squash to a large mixing bowl with 1/2 cup of cheddar, 1/2 cup of Monterey jack, and the remaining ingredient. Stir well to combine. 
2. Spoon the mixture back into the empty spaghetti squash shell and top with the remaining cheeses. 
3. Bake at 350 degrees for 15-20 minutes or until hot and bubbly.
4. Drizzle with ranch dressing and extra hot sauce, if desired. Sprinkle with green onions and blue cheese before serving.
