Directions

1. Preheat oven to 375 degrees F. Lightly oil a baking sheet or coat with nonstick spray.
2. Cut the squash in half lengthwise from stem to tail and scrape out the seeds.* Drizzle with olive oil and season with salt and pepper, to taste.
3. Place squash, cut-side down, onto the prepared baking dish. Place into oven and roast until tender, about 35-45 minutes.
4. Remove from oven and let rest until cool enough to handle.
5. Using a fork, scrape the flesh to create long strands.
6. Melt butter in a saucepan over medium heat. Add garlic, and cook, stirring frequently, until fragrant, about 1-2 minutes. Whisk in flour until lightly browned, about 1 minute.
7. Gradually whisk in milk, half and half, thyme and oregano. Cook, whisking constantly, until incorporated, about 1-2 minutes. Stir in cheeses until slightly thickened, about 1-2 minutes. If the mixture is too thick, add more milk as needed; season with salt and pepper, to taste.
8. Stir in spaghetti squash until well combined.
9. Serve immediately, garnished with chives, if desired.
