Ingredients
- 1 large spaghetti squash
- 2 cups cooked chicken breast, cubed
- 2 cups Alfredo sauce
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
- 1/4 cup chopped fresh parsley
- 1 teaspoon garlic powder
- Salt and pepper to taste
- Olive oil for roasting

Instructions
- Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper.
- Carefully slice the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the cut sides with olive oil and season with salt and pepper.
- Place the squash halves cut-side down on the prepared baking sheet and roast in the preheated oven for about 40 minutes, or until the flesh is tender and easily separates into strands with a fork.
- Remove the squash from the oven and let it cool slightly. Once cool enough to handle, use a fork to scrape the strands of squash into a large bowl.
- In the bowl with the spaghetti squash, add the cooked chicken, Alfredo sauce, garlic powder, salt, and pepper. Mix until well combined.
- Transfer the mixture to a greased 9×13-inch baking dish. Sprinkle the mozzarella and Parmesan cheeses evenly over the top.
- Bake the casserole in the oven for 20-25 minutes, or until the cheese is melted and bubbly.
- Remove from the oven and let it cool for a few minutes. Garnish with freshly chopped parsley before serving.
Helpful Tips
For a quicker version, you can use store-bought pre-cooked chicken. If you prefer a vegetarian version, substitute the chicken with sautéed mushrooms or your favorite veggies. To make this recipe dairy-free, use a vegan Alfredo sauce and dairy-free cheese alternatives.
Storage Instructions
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply bake at 350°F (175°C) until heated through.

Pairings
This casserole pairs wonderfully with a simple green salad and a refreshing glass of lemon water or sparkling apple cider.
