Andre's Onion Tart

6 Serves

Sautéed onions are the star ingredient here, imparting a pronounced and slightly sweet flavor. This recipe has been adapted from "The Lutece Cookbook" by Andre Soltner with Seymour Britchky.


  • 12 tablespoons (1 ½ sticks) cold, unsalted butter, cut into small pieces, plus more for tart pan

  • 2 cups all-purpose flour, plus more for dusting

  • 1 ½ teaspoons salt

  • ½ cup ice water

  • 1 ½ pounds onions, finely chopped

  • 1 large egg, lightly beaten

  • ½ cup heavy cream

  • ¼ teaspoon freshly ground pepper

  • 1 pinch freshly grated nutmeg

  • ¼ cup freshly grated Parmesan or Swiss cheese


  1. Butter a 10-inch tart pan with removable bottom; set aside.

  2. Make the crust: In a medium bowl, combine flour and 1/2 teaspoon salt. Add 8 tablespoons (1 stick) chilled butter, and combine with fingers or a pastry blender until it has the texture of coarse meal. Add 1/2 cup ice water, and stir just until a dough forms. Form into a disk, and wrap in plastic wrap. Chill for at least 15 minutes.

  3. Preheat oven to 375 degrees. On a lightly floured surface, roll out dough to 1/8-inch-thick round. Fit dough into prepared tart pan; trim excess. Line with a parchment paper round, and fill with pie weights. Chill for 15 minutes. Transfer to oven, and bake for 15 minutes. Remove pie weights and parchment paper. Bake for 5 minutes more. Remove from oven, and set aside.

  4. In a large skillet, heat remaining 4 tablespoons butter. Add onions, and cook, stirring frequently, until slightly browned and softened, about 15 minutes. Remove from heat.

  5. In a small bowl, combine beaten egg, cream, remaining 1 teaspoon salt, pepper, and nutmeg. Stir in onions.

  6. Sprinkle baked tart shell with cheese. Spread onion mixture evenly over cheese. Bake until set, 35 to 40 minutes. Serve immediately.
