Ingredients

Scale

Main Ingredients:

  • 2 medium spaghetti squash (about 34 pounds total)
  • 3 cups cooked chicken (shredded or diced)
  • 2 cups Alfredo sauce
  • 1 cup mozzarella cheese (shredded)
  • 1/2 cup Parmesan cheese (grated)

Cheese and Seasonings:

  • 1 teaspoon garlic powder
  • 1 teaspoon Italian seasoning
  • Salt (to taste)
  • Pepper (to taste)
  • 1 tablespoon olive oil

Optional Add-ins:

  • 1 cup steamed broccoli
  • 1 cup sautéed mushrooms

Garnish:

  • Fresh parsley (chopped, optional)
  • Fresh basil (chopped, optional)

Instructions

  1. Prepare the oven at 400°F (200°C) for roasting the spaghetti squash.
  2. Carefully halve the spaghetti squash lengthwise and remove the seeds using a spoon.
  3. Drizzle olive oil over the squash halves and season with salt and pepper, positioning them cut-side down on a baking sheet.
  4. Roast for 30–40 minutes until the squash becomes tender and easily pierced with a fork.
  5. Allow the squash to cool slightly, then gently extract the stringy flesh using a fork into a separate bowl.
  6. In a saucepan, melt butter over medium heat and sauté minced garlic until aromatic.
  7. Pour heavy cream into the pan and simmer for 3–4 minutes to develop rich flavors.
  8. Incorporate Parmesan cheese, whisking until the sauce becomes smooth and creamy.
  9. Enhance the sauce with salt, pepper, and an optional touch of nutmeg.
  10. Adjust the oven temperature to 375°F (190°C) and prepare a 9×13-inch casserole dish with a light grease.
  11. Create a thin Alfredo sauce base in the casserole dish.
  12. Construct the first layer using half the spaghetti squash strands, chicken, and Alfredo sauce, sprinkling Parmesan cheese.
  13. Repeat the layering process, topping with mozzarella cheese for a golden finish.
  14. Cover the dish with foil and bake for 20 minutes to allow flavors to meld.
  15. Uncover and continue baking for 10–15 minutes until the cheese turns bubbly and golden brown.
  16. Garnish with fresh herbs like parsley or basil and serve alongside a crisp salad or roasted vegetables.

Notes

  • Enhance the roasting process by piercing the squash with a fork before baking to help steam escape and prevent potential bursting.
  • Drain excess moisture from cooked spaghetti squash using a clean kitchen towel to prevent a watery casserole texture.
  • Swap heavy cream with Greek yogurt or coconut milk for lighter, dietary-friendly alternatives that maintain creamy consistency.
  • Incorporate additional vegetables like spinach or zucchini to boost nutritional value and add extra flavor complexity.
