Common Mistakes to Avoid

- Skipping the Resting Time: Cutting into your casserole too soon can make it fall apart. Allow it to rest for 10 minutes before serving for better slices.
- Using Low-Quality Cheese: Cheap cheese may not melt well or provide the desired flavor. Opt for good quality mozzarella for a deliciously gooey topping.
- Ignoring Seasoning Adjustments: Everyone’s taste is different. Don’t hesitate to adjust seasoning based on personal preference; add more Italian herbs or spices if desired.
