Preheat oven to 425 degrees. Place potatoes and carrot in a large saucepan; add water to cover. Bring to a boil. Reduce heat; cook, covered, 8-10 minutes or until crisp-tender; drain.
In a large skillet, heat butter over medium-high heat. Add onion; cook and stir until tender. Stir in flour and seasonings until blended. Gradually stir in broth and milk. Bring to a boil, stirring constantly; cook and stir 2 minutes or until thickened. Stir in chicken, peas, corn and potato mixture; remove from heat.
Unroll a pastry sheet into each of two 9 inch pie plates; trim even with rims. Add chicken mixture. Unroll remaining pastry; place over filling. Trim, seal and flute edges. Cut slits in tops.
Bake 35-40 minutes or until crust is lightly browned. Let stand 15 minutes before cutting.
Lisa’s Notes: Potpie is a favorite of mine and I have always been on the lookout for an easy, delicious recipe that has a savory and creamy filling. I finally found it at tasteofhome.com. The best part is that the recipe makes 2 pies, one to eat and one to share.
