- If you prefer fresh garlic, use 2 cloves minced instead of garlic powder.
- Use Greek yogurt instead of sour cream for a tangier and healthier option.
- Add a crunchy topping by mixing breadcrumbs with melted butter and sprinkling on top before baking without foil in the last 10 minutes.
Storage
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm the entire dish in the oven at 350°F (175°C) until heated through. For longer storage, freeze the casserole uncovered until solid, then cover tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

FAQs
Can I make this casserole ahead of time?
Yes, you can assemble the casserole a few hours ahead and keep it covered in the refrigerator. Bake just before serving, adding a few extra minutes if baking straight from cold.
Can I use brown rice instead of white rice?
Absolutely! Brown rice works well, though it may need a slightly longer cooking time and will give the dish a nuttier flavor.
