Common Mistakes to Avoid

Boldly choosing the wrong mushrooms: Using smaller or different types of mushrooms can lead to uneven cooking. Stick to large Portobello mushrooms for consistent flavor and texture.

Boldly neglecting moisture control: Failing to dry the mushrooms properly can lead to a soggy filling. Make sure to wash and dry them thoroughly before stuffing.
Boldly overstuffing the mushrooms: Adding too much filling can make it difficult to cook evenly. Fill each mushroom generously but avoid overflowing for best results.
