Reuben Puff Pastry Sandwiches
Serves: 9
 
Ingredients
  • 1 (17.3-ounce) package frozen puff pastry dough (2 sheets), slightly thawed but still firm
  • 1 large egg
  • 1 tablespoon water
  • 3 tablespoons unsalted butter, softened
  • 1 cup loosely packed spring mix lettuces
  • 27 very thin slices deli-style corned beef
  • 9 thin slices baby Swiss cheese
  • 6 tablespoons sauerkraut, well-drained and blotted dry
  • Russian Dressing (recipe follows)
Instructions
  1. Preheat oven to 400°. Line a rimmed baking sheet with parchment paper.
  2. On a lightly floured cutting surface, unfold puff pastry dough. Using a sharp knife, cut 9 (approximately 2 1⁄2x1 1⁄2-inch) rectangles from dough. Place rectangles on prepared baking sheet.
  3. Using a rolling pin, roll out remaining dough to flatten. Using a very small (1 1⁄4-inch) shamrock-shaped cutter, cut shapes from dough.
  4. In a small bowl, whisk together egg and 1 tablespoon water to make an egg wash. Using a pastry brush, spread egg wash over tops of rectangles. Place a shamrock shape on top of each rectangle. Brush tops of shamrock shapes with egg wash.
  5. Bake until pastry rectangles are puffed and deep golden brown, 13 to 15 minutes. Let cool completely on baking sheet.
  6. Using a sharp knife, carefully split each pastry rectangle in half horizontally. Store cooled pastry rectangles in an airtight container until ready to fill, and use within 3 hours for best texture.
  7. To assemble sandwiches, spread a thin layer of butter onto cut surface of bottom half of each pastry rectangle. (This will keep Russian Dressing from soaking into pastry.) Spread a layer of Russian Dressing over butter layer. Top dressing layer with spring mix lettuces; 2 to 3 corned beef slices, ruffling and gathering to fit; a cheese slice, trimming to fit pastry; and a thin layer of sauerkraut. Spread a thin layer of Russian dressing onto cut surface of top half of each pastry rectangle. Top sauerkraut layer with pastry rectangles, dressing side down, to make 9 sandwiches. Serve immediately.
