directions
Preheat your oven to 400°F (200°C). Slice the spaghetti squash in half lengthwise and scoop out the seeds.
Drizzle the inside of each half with olive oil, then season with salt and pepper. Place cut-side down on a baking sheet and roast for 35-40 minutes, or until tender.
While the squash roasts, heat a skillet over medium heat. Cook the sausage until browned and cooked through, breaking it up with a spoon.
Add chopped onion and garlic to the skillet and sauté until soft and fragrant. Stir in red pepper flakes, salt, and black pepper.
Reduce the heat to low and mix in the cream cheese until melted and combined. Stir in grated Parmesan and remove from heat.
Once the squash is done, use a fork to gently shred the flesh into spaghetti-like strands, leaving them in the shell.
Spoon the sausage mixture evenly into each squash half, then top with shredded mozzarella.
Return to the oven and bake for 10-15 minutes, or until the cheese is melted and bubbly. Broil for 2-3 minutes for a golden top, if desired.
Garnish with chopped parsley before serving.
