Instructions

Prepare the Spaghetti Squash. Preheat your oven to 400°F (200°C).
Slice the spaghetti squash in half lengthwise and scoop out the seeds. Brush the inside with olive oil and season with salt and pepper.
Place the squash halves cut-side down on a parchment-lined baking sheet. Roast for 40–50 minutes, or until the flesh is tender and easily shreds with a fork.
Remove from the oven and let it cool slightly.
Prepare the Casserole Mixture.
While the squash is roasting, combine the cream cheese, mozzarella, Parmesan, sour cream, and minced garlic in a large bowl.
Mix until smooth and well combined. Add the spinach and shredded chicken, then season with pepper and stir until evenly mixed.
Shred the Spaghetti Squash.
Once the squash is cool enough to handle, use a fork to gently scrape the flesh into spaghetti-like strands.
Add the shredded squash to the chicken and cheese mixture, and mix until fully combined.
Assemble and Bake the Casserole.
Lightly grease a baking dish and transfer the mixture into it, spreading evenly.
Bake for 20–25 minutes, or until hot, bubbly, and lightly golden on top.
Serve. Remove from the oven and let it cool for a few minutes before serving.

Notes

Pro Tip: Taste the casserole mixture before baking (if your chicken is fully cooked). You can adjust the salt and pepper as needed, especially if your cheeses are already salty.
