Description

A creamy and comforting Chicken Alfredo Spaghetti Squash Casserole that combines tender spaghetti squash, shredded chicken, and a rich Alfredo sauce baked to golden perfection.


Ingredients

Units Scale
  • 1 large spaghetti squash
  • 2 cups cooked chicken, shredded
  • 2 tbsp olive oil
  • 3 cloves garlic, minced
  • 1 cup heavy cream
  • 1/2 cup cream cheese, softened
  • 1 cup grated Parmesan cheese
  • 1/2 tsp Italian seasoning
  • Salt and pepper, to taste
  • 1 cup shredded mozzarella cheese
  • 2 tbsp chopped parsley (optional)

Instructions

  1. Preheat oven to 400°F (200°C). Slice the spaghetti squash in half lengthwise, remove seeds, and brush the inside with olive oil.
  2. Place squash cut-side down on a baking sheet and roast for 35–40 minutes, or until tender. Let cool slightly, then use a fork to scrape out the strands.
  3. Reduce oven temperature to 375°F (190°C). In a skillet, heat remaining olive oil and sauté garlic until fragrant, about 1 minute.
  4. Stir in heavy cream, cream cheese, Parmesan cheese, Italian seasoning, salt, and pepper. Cook, stirring, until smooth and thickened.
  5. In a large bowl, combine cooked spaghetti squash strands, shredded chicken, and Alfredo sauce. Mix until evenly coated.
  6. Transfer mixture to a greased 9×13-inch baking dish. Top with shredded mozzarella cheese.
  7. Bake for 20–25 minutes, or until cheese is melted and bubbly. Broil for 2–3 minutes if desired for a golden top.
  8. Garnish with chopped parsley and serve warm.

Notes

  • Use rotisserie chicken for a time-saving shortcut.
  • Add steamed broccoli or spinach for extra veggies.
  • Can be assembled ahead and baked just before serving.
