Ingredients

Scale
  • 1 large spaghetti squash
  • 2 cups shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 1 cup heavy cream or coconut milk (for dairy-free options)
  • 2 tablespoons olive oil
  • 3 cloves garlic, minced
  • 1 teaspoon dried thyme or Italian seasoning
  • Salt and pepper to taste
  • Fresh parsley, chopped (for garnish)

Instructions

  1. Preheat the oven to 400°F (200°C). Cut the spaghetti squash in half lengthwise, scoop out seeds, brush with olive oil, season with salt and pepper, and roast for 40-45 minutes until tender.
  2. While roasting, heat olive oil in a skillet over medium heat. Sauté minced garlic until fragrant, add heavy cream or coconut milk with thyme, simmer for 2-3 minutes, then stir in shredded mozzarella and Parmesan until melted.
  3. Cool the cooked squash slightly, then shred flesh into strands using a fork. Transfer to a large bowl, pour the cheese sauce over, and toss to coat evenly.
  4. Transfer the mixture to a greased baking dish. Preheat oven to 375°F (190°C).
  5. Bake the assembled dish for 20-25 minutes until bubbly and golden. Add extra cheese on top if desired.
  6. Garnish with chopped parsley or basil. Serve hot, optionally with salad or roasted vegetables.

Notes

  • Feel free to add sautéed vegetables or cooked chicken for extra flavor and protein.
