  • 1 Spaghetti squash 3-4 lbs
  • 2 Teaspoons of Extra Virgin Olive Oil
  • ¼ Teaspoon of salt
  • ¼ Teaspoon of black pepper
  • ¼ Cup water
  • 1 Cup heavy cream
  • 3 Oz cream cheese room temperature
  • ¾ cup of Parmesan cheese separated
  • 2 tablespoon of unsalted butter room temperature
  • ½ teaspoon of garlic powder
  • 1 Pinch white pepper
  • 1 Pinch freshly ground nutmeg
  • ¼ Cup of shredded mozzarella
  • minced fresh parsley or thyme optional/ for garnish


  • Cut spaghetti squash in half and remove all the seeds.
  • Drizzle the inside of the squash with olive oil and rub to cover the inside of the squash. Sprinkle with salt and pepper.
  • Place squash halves, cut sides down, in an 8x8 casserole dish; add the ¼ cup water. Microwave, covered, on high for 15 minutes. Or until tender.
  • While the squash is in the microwave, start working on the Alfredo sauce. In a medium saucepan over medium heat, place the cream cheese and butter. Once melted, slowly incorporate the heavy cream and ½ cup of Parmesan cheese. Once well combined, whisk in the garlic, pepper and nutmeg. Set to low heat and whisk occasionally.
  • Once your spaghetti squash is tender, cool slightly and separate strands of squash with a fork. Spread the strands evenly onto the same 8x8 dish you cooked it in. Evenly pour the Alfredo sauce over the top of the squash stands.
  • Top with the mozzarella cheese and ¼ cup of Parmesan cheese and place uncovered in the oven under broil until cheese is slightly browned and bubbly (about 3-5 minutes)
  • Garnish with fresh thyme or parsley
