Buttermilk Leek Tart

  • yield: Makes 1 nine-inch tart




  • All-purpose flour, for work surface
  • 1 sheet frozen puff pastry, from standard package (17.3 ounces), thawed
  • 2 tablespoons unsalted butter
  • 5 leeks, white and pale-green parts only, washed well, and cut crosswise into 1/2-inch-thick pieces
  • 1/4 cup nonfat buttermilk
  • 2 teaspoons Dijon mustard
  • Coarse salt and freshly ground pepper
  • 5 ounces fresh goat cheese, crumbled
  • 1 large egg yolk
  • 1 tablespoon heavy cream, or water


  1. Step 1

    Line a baking sheet with parchment paper, and set a 9-inch tart ring (about 2 inches deep) or the hoop of a 9-inch springform pan on top; set aside. On a lightly floured work surface, roll out puff pastry about 1/8-inch-thick. Using a sharp paring knife, cut into a 13-inch round, and lay over tart ring. Fit into ring, and fold in edges against the inside of the ring, pressing gently to seal. Refrigerate 20 minutes.

  2. Step 2

    Preheat oven to 400 degrees. In a large nonstick skillet set over medium heat, melt butter. Add leeks, and cook, stirring, until soft, about 7 minutes. Add buttermilk and mustard, and cook until slightly thickened, about 2 minutes. Season with salt and pepper. Remove from heat; set aside.

  3. Step 3

    To assemble tart, layer goat cheese and leek mixture on chilled pastry, ending with goat cheese. In a small bowl, beat together egg yolk and cream. Brush pastry with egg wash, and bake until golden, about 35 minutes. Serve warm.
