Mushroom Strudel

This mushroom strudel wraps a rich filling of sauteed mushrooms, Black Forest ham, mozzarella, and Dijon mustard inside layers of buttered phyllo dough, then bakes until shattering-crisp and golden. Sliced on the diagonal, each piece reveals a spiral of flaky pastry around a savory, earthy core.

Seven cups of sliced mushrooms cook down dramatically over medium-high heat. You need to evaporate all the moisture they release, otherwise the filling soaks through the phyllo and turns it soggy. Keep cooking and stirring until the pan is dry and the mushrooms are concentrated and deeply flavored. Thyme, lemon juice, and a strip of Dijon mustard layered on the phyllo before the filling add brightness and a peppery bite.

Breadcrumbs mixed into the filling act as insurance, absorbing any remaining moisture so the pastry stays crisp. The Parmesan dusted over the filling before rolling adds salty, nutty flavor that melts into the mushrooms during baking.

Chef Tips

• Work quickly with phyllo. It dries out fast. Keep unused sheets covered with a damp towel while you assemble.
• Brush each sheet with melted butter generously. The butter between layers is what creates the flaky, shatteringly crisp texture.
• Score the top of each roll through only the top two layers of phyllo before baking. This makes clean slices after baking without crushing the delicate pastry.
• Let the strudel cool 5 minutes before slicing. Hot phyllo shatters into shards if cut immediately.

Variations

• Use wild mushrooms (chanterelles, shiitakes, or a mix) for a more intense, woodsy flavor.
• Skip the ham for a vegetarian version. The mushrooms carry enough flavor on their own.
• Add a handful of fresh spinach to the filling for color and extra vegetables.
