Ingredients

Scale

Spaghetti Squash

  • 1 medium spaghetti squash, halved lengthwise, seeds removed
  • 1 tbsp extra-virgin olive oil
  • Kosher salt, to taste
  • Freshly ground black pepper, to taste

Chicken

  • 2 boneless, skinless chicken breasts
  • 2 tbsp extra-virgin olive oil
  • Kosher salt, to taste
  • Freshly ground black pepper, to taste

Alfredo Sauce

  • 1 tbsp extra-virgin olive oil
  • 3 cloves garlic, finely chopped
  • 1 1/2 cups whole milk
  • 3/4 cup low-sodium chicken broth
  • 1 cup heavy cream
  • 3/4 cup finely grated Parmesan cheese
  • Pinch of crushed red pepper flakes
  • Kosher salt, to taste
  • Freshly ground black pepper, to taste

Topping

  • 1 cup shredded mozzarella cheese
  • Chopped fresh parsley, for serving

Instructions

  1. Preheat and Prepare Squash: Preheat your oven to 400°F. Drizzle the cut sides of the spaghetti squash with 1 tablespoon of olive oil, then season with kosher salt and freshly ground black pepper. Place the squash halves cut side down on a large baking sheet.
  2. Roast Squash: Roast the squash in the oven for 30 to 35 minutes until tender. Once done, allow it to cool slightly. Use a fork to scrape out the strands of spaghetti squash into a large bowl, reserving the hollowed-out squash shells for later use. Keep the oven on for baking at the end.
  3. Cook Chicken: Season both sides of the chicken breasts with salt and pepper. Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add the chicken breasts and cook, turning occasionally, until golden brown and cooked through, roughly 8 minutes on each side. Transfer the chicken to a cutting board and let rest for 5 minutes. Cut into bite-sized pieces.
  4. Make Alfredo Sauce: In the same skillet, add the remaining tablespoon of olive oil and heat over medium heat. Add the finely chopped garlic and cook by stirring for about 1 minute until fragrant. Pour in the whole milk and chicken broth, bringing the mixture to a simmer. Stir in the heavy cream, Parmesan cheese, and a pinch of crushed red pepper flakes, seasoning with salt and black pepper as needed. Continue to simmer, stirring occasionally, until the sauce thickens, about 15 minutes.
  5. Combine Ingredients: Add the cooked chicken and Alfredo sauce to the bowl with the scraped spaghetti squash strands. Toss everything well to combine evenly.
  6. Fill and Top Squash Boats: Divide the chicken and spaghetti squash mixture evenly between the reserved spaghetti squash halves. Sprinkle the tops with shredded mozzarella cheese.
  7. Bake Squash Boats: Return the stuffed squash halves to the oven and bake until they are warmed through and the mozzarella cheese is melted and bubbly, approximately 15 minutes.
  8. Garnish and Serve: Transfer the squash halves to a serving platter. Sprinkle chopped fresh parsley on top and serve immediately.

Notes

  • Use cold chicken breasts to ensure even cooking and retain juiciness.
  • For a lower-fat version, substitute heavy cream with half-and-half and reduce the amount of cheese.
  • To save time, prepare the Alfredo sauce while the squash is roasting.
  • Leftover stuffed squash can be stored in the refrigerator for up to 3 days and reheated in the oven.
  • Fresh parsley adds a bright finish and can be substituted with basil for a different flavor.
