Ingredients

  • 2 large dark orange sweet potatoes, peeled, cut into 1 1/2-inch pieces (about 2 lb)
  • 1/4 cup water
  • 1 box (14.1 oz) refrigerated Pillsbury™ Pie Crusts (2 Count), softened as directed on box
  • 1 cup packed brown sugar
  • 3 eggs
  • 1 1/2 cups half-and-half
  • 1 1/2 teaspoons lemon juice
  • 3/4 teaspoon ground cinnamon
  • 1/4 teaspoon ground ginger

Topping

  • 1 cup heavy whipping cream
  • 1 jar (7 oz) marshmallow creme

Steps

  • 1
    Heat oven to 450°F.
  • 2
    In large microwavable bowl, place sweet potatoes and water. Cover loosely with paper towel. Microwave on High 13 to 18 minutes, stirring twice, until potatoes are fork-tender and can be mashed (bowl will be HOT; handle carefully). Drain potatoes; rinse with cold water, and drain thoroughly. With potato masher, mash potatoes well. Measure 2 1/4 cups of the potatoes, and set aside to cool. Reserve any remaining potatoes for another use.
  • 3
    Remove pie crusts from pouches. On lightly floured surface, unroll and stack crusts one on top of the other. Roll to 17x12-inch rectangle.
  • 4
    Fit crust into 15x10x1-inch pan, pressing firmly into bottom, corners and sides. Fold extra crust underneath and slightly on top edges of pan; flute edges. Poke bottom and sides of crust with fork. Bake 7 to 9 minutes or until light golden brown; remove from oven to cooling rack.
  • 5
    Reduce oven temperature to 375°F.
  • 6
    In blender or food processor, add mashed sweet potatoes, brown sugar, eggs, half-and-half, lemon juice, cinnamon and ginger; cover securely, and blend mixture until smooth.
  • 7
    Pour filling mixture into pan. Bake 23 to 28 minutes or until center of filling is set. Cool on cooling rack 30 minutes. Refrigerate at least 1 hour until completely cool.
  • 8
    In chilled medium bowl, beat whipping cream until stiff peaks form; add marshmallow creme, and beat until blended and smooth. Cut pie into 4 rows by 4 rows. Serve with topping. Store loosely covered in refrigerator.

Tips from the Pillsbury Kitchens

  • tip 1
    Microwave sweet potatoes first to allow them to cool before using in pie filling.
  • tip 2
    Press pie crust firmly into bottom and sides of pan to avoid any bubbles in crust during prebake.
  • tip 3
    This recipe has two different oven temperatures. The initial oven temperature of 450°F ensures the pie crust is browned and set, while the second oven temperature of 375°F bakes the filling. Be sure to remember to reduce the oven temperature before adding the filling to the crust.
  • tip 4
    For a pretty presentation, pipe marshmallow whipped topping onto individual servings of pie. Transfer whipped topping to a piping bag fitted with a round tip, then pipe onto pie.
