Method

  • Prepare a medium heat fire (375F) in a wood-fired oven or cooker.
  • Brush an 8-inch springform pan with olive oil.
  • To make the filling, heat the olive oil in a saute pan over medium heat and saute the onions for 5 minutes.
  • Add the spinach and saute for another 5 minutes.
  • Add the white wine and cook until the liquid is mostly evaporated.
  • Add the capers, salt, and white pepper.
  • Remove from the heat, stir in the dill, and let cool.
  • Stir in the feta.
  • Saute or oven-roast the mushrooms separately in 2 tablespoons of olive oil with a little salt until almost dry.
  • Remove from the heat.
  • Season with white pepper and more salt if needed.
  • Set aside in separate bowls.
  • Melt the butter in a small saucepan over medium heat and stir in the remaining olive oil.
  • Set aside and keep warm.
  • Combine the bread crumbs, dill, thyme, pimenton, zest, and salt in bowl.
  • Set aside.
  • Lay the phyllo on a work space and cover with a kitchen towel, then damp paper towels.
  • On a cutting board, lay one pastry sheet lengthwise and, starting in the center, brush to the edges with the butter mixture.
  • Generously sprinkle with the breadcrumb mixture.
  • Cover with another sheet and brush with the butter mixture as before.
  • Generously sprinkle with more of the bread-crumb mixture.
  • Cover with a third sheet and brush again.
  • Cut about 2 inches off one short side.
  • Gently place the stacked sheets in the springform pan, pressing down to the bottom and draping the excess over the edges of the pan.
  • Fill with the shiitake mushrooms.
  • Repeat the phyllo layering process with three more sheets of pastry, the butter mixture, and the bread crumbs.
  • Cut about 2 inches off one short side.
  • Gently place these sheets in the springform pan, pressing down over the mushrooms and draping the excess over the edges of the pan.
  • Fill with half of the spinach-onion mixture.
  • Repeat the phyllo layering process and trimming again.
  • Layer in the pan as before, and fill with the oyster mushrooms.
  • Repeat the phyllo layering process, trimming, and layering in the pan.
  • Fill with the remaining spinach-onion mixture.
  • Cover with the bread-crumb mixture.
  • Fold all the excess draped phyllo into the center to cover the spinach-onion mixture and create the top crust.
  • Generously brush with the butter mixture and bake in the oven for 25 to 30 minutes, or until the top is golden and the crust is crisp.
  • Remove from the oven and let cool for 15 minutes before removing from the springform pan.
  • Cut into wedges and serve warm.
