Ingredients

  • 1 tablespoon butter
  • 1 leek, white and light green parts, finely chopped (1/2 cup)
  • 1/2 medium yellow onion, finely chopped (1/2 cup)
  • 1 large egg, lightly beaten
  • 1/2 cup light cream
  • 1/8 teaspoon nutmeg
  • 1/4 teaspoon kosher salt
  • 1/8 teaspoon freshly ground pepper
  • 1/4 cup finely chopped blanched broccoli rabe florets, squeezed dry
  • 1/4 cup finely chopped pancetta, optional
  • 30 prebaked miniature phyllo shells (two 15-ounce packages)

Method

  • Preheat the oven to 350°.
  • In a large skillet, melt butter over medium-low heat. Add the leeks and onions and cook, stirring occasionally, until soft (810 minutes). Remove from heat and set the mixture aside to cool slightly (about 10 minutes).
  • Whisk together egg, cream, nutmeg, salt, and pepper in a bowl. Once the onion mixture is cool, add to egg mixture. Divide broccoli rabe and, if using, pancetta among shells. Fill each shell about 3/4 full with custard mixture. Bake until the custard sets (1015 minutes). Serve warm or at room temperature.
