Forgetting seasoning: Underseasoning can make the dish bland. Taste as you layer and adjust salt and pepper throughout the cooking process.
Not letting it rest: Cutting into the bake immediately after cooking can cause it to fall apart. Allow it to rest for at least 10 minutes for better slicing and flavor melding.
Using low-quality cheese: Cheap cheese may not melt properly and can affect creaminess. Opt for high-quality Gruyère or mix in other flavorful cheeses for the best results.
