Preheat oven to 375°F. Cut the spaghetti squash in half, lengthwise, and remove the seeds.
Place the squash halves cut side down on a baking sheet and bake for 30 minutes.
Remove from the oven and let cool for 10 minutes before scraping out the spaghetti-like strands of squash.
In a large saucepan, melt the butter over medium heat. Add the flour and whisk until it is completely incorporated.
Slowly add the milk, whisking constantly, until the sauce is smooth and thickened.
Stir in the garlic powder, onion powder, salt, and pepper.
Remove the saucepan from the heat and stir in the Parmesan cheese until melted.
Place the spaghetti squash in an oven-safe baking dish. Pour the sauce over the top, and top with the Cheddar cheese. Bake for 25 minutes, or until the cheese is golden brown.
Serve and enjoy!
