Common Mistakes to Avoid

When making your Green Bean and Potato Casserole, it’s easy to overlook some details that can affect the final dish. Here are common mistakes to watch out for.

• Overpacking the Baking Dish: Filling your baking dish too full can cause uneven cooking. Ensure you leave some space for bubbling and expansion during baking.

• Choosing the Wrong Cheese: Using low-quality cheese can affect flavor and texture. Opt for good quality cheddar and Parmesan for the best results.
