Calories 445kcal


  • 1 tablespoon olive oil
  • 1 medium spaghetti squash halved and seeded
  • 2 tablespoons butter
  • 3 cloves garlic minced
  • 2 tablespoons white whole wheat flour
  • 1-1/4 cups milk
  • 1/4 cup half-and-half
  • 1/4 teaspoon ground nutmeg
  • 1/3 cup grated Parmesan cheese
  • 2 cups cooked diced chicken
  • 2 cups baby spinach roughly chopped
  • Salt and pepper to taste
  • 1 cup shredded cheddar cheese


  • Preheat oven to 400F. Drizzle olive oil over cut side of spaghetti squash halves and place upside-down on a baking sheet. Bake spaghetti squash at 400F 30-40 minutes or until tender. Remove from oven and once cool enough to handle, use a fork to shred inside of boats into spaghetti strands. Set aside.
  • In a medium saucepan over medium-high heat, saute garlic in butter until just fragrant. Whisk in flour until smooth, then gradually add milk and half-and-half, whisking constantly until combined. Bring sauce to a simmer over medium-high heat, stirring occasionally until thickened. Remove from heat and stir in nutmeg, Parmesan, chicken, spinach, and salt and pepper to taste.
  • Divide chicken alfredo sauce between the two spaghetti squash boats and gently toss with fork until filling is combined. Divide cheddar cheese between the two boats, sprinkling evenly on top.
  • Bake spaghetti squash boats an additional 15-20 minutes at 375F until cheese is melted and filling is bubbly. Enjoy spaghetti squash right away!
