- Preheat oven to 400 degrees. Fill the pie pan with the piecrust and place on a rimmed baking sheet.
- Pour the filling into the piecrust and sprinkle with pecans. Place on the top or upper-middle rack of the oven and bake for 10 minutes; then lower the heat to 350 degrees and bake for another 45−50 minutes. Cover the edges of the crust with aluminum foil as needed to prevent over-browning. Cool the pie in the pan on a wire rack.
- Mix together the sugar, flour, cinnamon, salt, and apples; then combine with the egg and butter.
