- 5 pounds fresh spinach, stems removed
- 1 cup (2 sticks) unsalted butter
- 3 cloves garlic, finely sliced
- 1 pound ricotta cheese
- 2 tablespoons coarse salt
- 1 3/4 teaspoons freshly ground black pepper
- 3 pounds wild mushrooms, (chanterelles, oyster, and shiitake), trimmed, cut into 1-inch pieces
- 3/4 cup Madeira wine
- 1/2 cup chopped fresh flat-leaf parsley
- 4 1/2 cups milk
- 1/2 cup all-purpose flour
- 1/2 teaspoon ground nutmeg
- 1 cup grated Pecorino Romano cheese
- 1 one-pound package fresh spinach lasagna sheets
Wash spinach leaves well in three changes of cold water; shake dry. Melt 1 tablespoon butter in large pan over medium heat. Add half the garlic; saute until light golden, about 2 minutes. Add half the spinach leaves, cover, and cook, stirring occasionally, until wilted, 4 to 5 minutes. Drain spinach in a colander. Repeat with another tablespoon butter and remaining garlic and spinach. When spinach is cool enough to handle, squeeze to rid it of liquid. Roughly chop spinach; place in medium bowl. Add ricotta, 2 teaspoons salt, and 1 teaspoon pepper.
Melt 2 tablespoons butter in a large skillet over medium heat. Add a third of the mushrooms; season with 1 teaspoon salt and 1/4 teaspoon pepper. Saute until mushrooms are softened and browned, about 10 minutes. Deglaze skillet by pouring 1/4 cup Madeira into hot skillet with mushrooms and using a wooden spoon to loosen bits cooked onto skillet. Cook mushrooms until liquid has almost evaporated. Transfer cooked mushrooms to medium bowl. Repeat with another 2 tablespoons of butter, another third of the mushrooms, and 1/4 cup Madeira. (Reserve the final third of mushrooms and Madiera for topping.) Add two-thirds of the chopped parsley to bowl with cooked mushrooms; stir.
In medium saucepan over medium heat, heat 4 cups milk. Melt 8 tablespoons butter in medium saucepan over medium heat. When butter bubbles, add flour; cook, stirring constantly, 1 minute. Slowly add warmed milk; cook, whisking constantly, until mixture bubbles and becomes thick. Remove pan from heat. Stir in 2 teaspoons salt, 1/4 teaspoon pepper, the nutmeg, and 1/2 cup grated cheese.
Heat oven to 350 degrees. Set aside 1/2 cup sauce. Assemble lasagna: Spread 1/2 cup sauce in bottom of 9-by-13-inch baking pan. Place layer of lasagna sheets in pan, trimming to fit; spread 1 cup spinach mixture, 1 cup mushroom mixture, and 1/2 cup sauce on top of lasagna sheets. Repeat layers several times. For last layer, place a layer of lasagna sheets on top; spread 1/2 cup sauce over lasagna sheets. Sprinkle with 1/2 cup grated cheese. Bake lasagna until top is golden brown, 1 to 1 1/4 hours. Let stand 20 minutes before serving.
Just before serving, melt remaining 2 tablespoons butter in the skillet over medium heat. Add remaining third of the uncooked mushrooms; season with the remaining teaspoon salt and 1/4 teaspoon pepper. Cook until golden and tender, about 10 minutes. Deglaze skillet, with mushrooms in it, with the remaining 1/4 cup Madeira. Stir in the remaining third of fresh parsley.
In a small saucepan, combine reserved 1/2 cup sauce with remaining 1/2 cup milk. Over medium heat, whisk until warm and smooth. Spoon cooked mushrooms over each serving, or serve on the side. Serve lasagna with warmed sauce.
