Tips & Variations
- For a richer flavor, substitute beef broth with homemade broth or add a splash of Worcestershire sauce to the beef mixture.
- Try mixing in sautéed mushrooms or bell peppers with the ground beef for added texture and nutrition.
- Use Swiss cheese for a more traditional French flavor, or mozzarella for a milder, creamier option.
- To make it lighter, substitute sour cream with Greek yogurt.
Storage
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and warm in a 350°F (175°C) oven until heated through, about 15-20 minutes. You can also microwave individual portions, but the oven method helps maintain crispiness of the onions.

FAQs
Can I use brown rice instead of white rice?
Brown rice can be used, but it requires a longer cooking time and more liquid. If substituting, pre-cook the brown rice or adjust the broth amount and bake time accordingly to ensure it cooks fully.
Is it possible to make this casserole ahead of time?
Yes, you can assemble the casserole ahead and refrigerate it covered for up to 24 hours before baking. Just add the French-fried onions and final baking step right before serving for the best texture.
