Ingredients

1 spaghetti squash (about 2 pounds), halved and seeded

3 tablespoons extra-virgin olive oil, divided

Coarse salt and freshly ground pepper

1 tablespoon lemon juice

1/2 cup chopped fresh flat-leaf parsley

1/2 teaspoon crushed red pepper flakes

1 tablespoon grated Parmesan cheese, for serving (optional)

Preparation

Preheat oven to 425 degrees. Drizzle squash flesh with 2 tablespoons olive oil and season with salt and pepper. Place cut side down on a parchment-lined rimmed baking sheet. Roast until squash is tender when pierced with a knife, about 1 hour.

When cool enough to handle, gently scrape squash with a fork to remove flesh in long strands and transfer to a medium bowl. Toss with remaining 1 tablespoon oil, lemon juice, and parsley. Season with salt and red-pepper flakes and serve sprinkled with cheese, if desired.
