Prep Time 15 mins

Total Time 1 hr 10 mins


  • 1 large spaghetti squash, halved longwise, seeds and membranes scooped out
  • olive oil, for brushing
  • 2 tablespoons butter
  • 4 cloves garlic, minced
  • 1 cup heavy cream, (Half & Half or milk will also work, but won't be as rich)
  • 1 cup freshly grated parmesan cheese
  • 1 teaspoon Italian seasoning
  • cups mozzarella cheese, divided
  • 6 ounces baby spinach
  • salt, to taste
  • fresh ground black pepper, to taste
  • chopped fresh parsley, for garnish, optional


  • Preheat oven to 400˚F. Line a baking sheet with parchment paper or foil.
  • Scoop out the seeds and stringy center from the squash and discard.
  • Place squash cut side up on the baking sheet. Brush with olive oil and sprinkle with salt and pepper; then turn them over, cut-sides down.
  • Bake for 35 to 40 minutes, or until tender. Let squash cool slightly, or until cool enough to handle.
  • Using a fork, shred the spaghetti squash while leaving about a 1/4-inch border around the sides.
    Set strings aside in a plate and transfer unfilled boats back to the baking sheet. Set aside.
  • In a large sauté pan melt butter over medium heat. Add garlic and cook for 20 seconds, or until fragrant.
  • Slowly pour in heavy cream and whisk. Continue to cook, stirring constantly, until just starting to thicken.
    Reduce heat to low, add parmesan and Italian seasoning; stir until combined. Remove from heat.
  • To the cream mixture, add the shredded spaghetti squash, 3/4 cup mozzarella cheese and the spinach; toss to coat.
    Taste for salt and pepper and adjust accordingly.
  • Divide mixture evenly among the squash boats.
  • Sprinkle with remaining mozzarella cheese.
    Return to oven and bake for 10 to 12 minutes, or until cheese is melted.
  • Remove from oven.
  • Cut squash boats in half.
  • Garnish with parsley and serve.
