- Skipping the seasoning: Failing to properly season your ground beef can lead to a bland casserole. Always add enough salt and spices for a flavorful base.

- Overloading with cheese: While cheese is essential, too much can overpower the dish. Stick to the recommended amount for balance.
- Neglecting the sauce: The special sauce is what gives this dish its Big Mac flavor. Don’t skimp on mayo, ketchup, and relish; it’s crucial for authenticity.
- Not allowing it to rest: Cutting into the casserole too soon can result in a messy serving. Let it rest for about 10 minutes before slicing.
- Ignoring cooking times: Every oven is different, so keep an eye on your casserole as it cooks. Use a thermometer to ensure it reaches the right temperature.
