Pro Tips for Perfecting Your Casserole

- Use a Meat Thermometer: Ensure your chicken is cooked thoroughly by checking that it reaches an internal temperature of 165°F.
- Add Vegetables: Incorporate veggies like broccoli or spinach for added nutrition and flavor.
- Experiment with Sauces: Mix in a little **chicken broth** with your **alfredo sauce** for a lighter option.
- Layer Wisely: To prevent the top from browning too quickly, cover the casserole with foil during the first half of baking.
- Let it Rest: After baking, let the casserole sit for about 5-10 minutes to set before serving.
