How to Make Spaghetti Squash Gratin

  1. Preheat oven to 400°F (200°C). Pierce a medium spaghetti squash (about 2-3 pounds) several times with a fork.
  2. Place the whole squash directly on a baking sheet and bake for 50-60 minutes, or until easily pierced with a fork.
  3. Remove from oven and let cool slightly. Once cool enough to handle, cut the squash in half lengthwise.
  4. Scoop out the seeds (reserve for roasting!) and scrape out the spaghetti-like flesh with a fork into a large bowl.
  5. In a separate bowl, whisk together 1/2 cup milk, 2 large eggs, 1 cup grated Gruyere cheese, 1/4 teaspoon nutmeg, 1/4 teaspoon salt, and a pinch of black pepper.
  6. Gently mix the cheese mixture with the spaghetti squash until evenly combined.
  7. Transfer the squash mixture to a lightly oiled 8x8 inch baking dish.
  8. Top with 1/2 cup breadcrumbs and 1/4 cup grated Parmesan cheese. Drizzle with 1 tablespoon olive oil.
  9. Bake for 25-30 minutes, or until golden brown and bubbly.
