Spaghetti Squash Chicken Casserole

Directions

  1. Preheat the oven: Set to 200°C (400°F). Line a baking sheet with parchment paper.
  2. Prepare the spaghetti squash: Cut the squash in half lengthwise and scoop out the seeds. Drizzle the cut sides with olive oil and season with salt and pepper. Place cut-side down on the prepared baking sheet. Roast for 30–40 minutes, until tender. Let cool slightly, then scrape the flesh with a fork into spaghetti-like strands.
  3. Cook the aromatics: In a large skillet, heat 1 tbsp olive oil over medium heat. Add onion and cook until softened, about 3 minutes. Add garlic and cook 30 seconds until fragrant.
  4. Combine chicken and sauce: Add shredded chicken to the skillet with the onions and garlic. Stir in heavy cream, 1 cup mozzarella, Parmesan, Italian herbs, paprika, salt, and pepper. Mix until creamy and well combined.
  5. Assemble the casserole: Reduce oven temperature to 180°C (350°F). In a greased 9x13 inch (23x33 cm) baking dish, layer the roasted spaghetti squash. Pour the chicken mixture over the squash and gently stir to combine. Top with remaining mozzarella cheese.
  6. Bake: Bake uncovered for 20–25 minutes, until the cheese is melted, bubbly, and lightly golden on top.
  7. Serve: Remove from the oven and let the casserole rest for 5 minutes. Garnish with fresh parsley or basil before serving.
