Equipment

  • silicone brush
  • parchment paper
  • baking sheets
  • nonstick skillet

Ingredients

Pastry:

  • 12 sheets phyllo pastry, thawed
  • 12 tablespoon butter, melted
  • 1 large egg, beaten

Filling:

  • 4 tablespoon butter
  • 16 oz cremini or baby Bella mushrooms, cleaned and thinly sliced
  • 6 oz shiitake mushrooms, cleaned, roughly chopped, tough stems removed 
  • 1 leek, thinly sliced and well cleaned (light green and white parts only)
  • 4 cloves garlic, minced 
  • ½ cup grated parmesan cheese
  • 2 tablespoon chopped parsley
  • salt and freshly ground black pepper, to taste

Instructions

Make the filling:

  • Preheat the oven to 400°F. Melt butter in a large nonstick frying pan over medium heat.
  • Once butter is melted, add sliced leeks. Cook 8-10 minutes until softened and slightly caramelized. Remove to a large mixing bowl.
  • Add all the mushrooms to the pan, and season with salt and pepper.
  • Cook the mushrooms, stirring occasionally for 12-15 minutes, until most liquid is removed.
  • Add the cooked mushrooms to the bowl with the leeks, and stir in parmesan, garlic and chopped parsley.

Assembly/Baking:

  • Line a cookie sheet with parchment paper, and brush lightly with melted butter so the phyllo pastry doesn’t stick.
  • Lay out one sheet of phyllo, brush with melted butter, top with another sheet of phyllo and brush again with butter. Repeat (using in total four sheet of dough).
  • Brush edges of dough with beaten egg.
  • Lay out ¼ of the mushroom mixture over one end of Phyllo dough, leaving about ¼” margin around. Use the parchment paper to push up the margin edge for the full length of the pastry, to create a seal around the mushrooms.
  • Carefully roll into a strudel toward the empty end of the phyllo pastry, tucking in the end to form a sealed strudel. (Use parchment to roll and tuck the the phyllo pastry and make it easier to work with). Repeat steps 2-5 until you have 4 strudel. To make the phyllo dough easier to work with, cover with a damp towel.
  • Brush the top of each sealed strudel with melted butter.
  • Bake seam side down until golden brown and crisp- about 15 minutes.
  • Allow to cool about 15 minutes, then slice into 3 or 4 pieces each and serve warm.

Notes

  • Thaw the phyllo properly. Thaw frozen phyllo overnight in the refrigerator for the easiest handling.
  • Keep phyllo covered. Phyllo dries out quickly, so keep unused sheets covered with a slightly damp kitchen towel while you work.
  • Cook off the mushroom liquid. Let most of the moisture evaporate before assembling the strudel so the pastry stays crisp instead of soggy.
  • Cool the filling slightly. Warm or room-temperature filling is easier on the delicate phyllo than piping-hot mushrooms.
  • Don’t overfill. Too much filling makes the strudel harder to roll and more likely to split.
  • Bake seam-side down. This helps the strudel stay closed as it bakes.
  • Let it rest before slicing. Cool for about 10–15 minutes so the filling sets and the slices hold together better.
  • Storage: Refrigerate leftovers in an airtight container for up to 4 days.
  • Reheating: Reheat at 350°F in the oven until warmed through, or in the air fryer for about 3–4 minutes to help restore the crisp phyllo.
