Tommy Habetz enjoys updating the savory strudels common in northern Italy and eastern France. He makes the crackly, caramelized crust here with buttered layers of phyllo instead of ultra-labor-intensive strudel dough. More Mushroom Dishes
The mushroom filling can be refrigerated for up to 2 days. Bring to room temperature before filling the phyllo.
Clean mushrooms right before using them. Wipe them gently with a damp cloth or paper towel, or rinse them quickly under cold water and dry them immediately. Do not soak them in water, because they absorb liquid like sponges. For hard-to-reach or stubborn dirt, clean the mushrooms with a soft brush (a small paint brush works well).
