                At the end of Thanksgiving dinner, most guests will take a small slice of pumpkin pie and a small slice of pecan pie, so we’ve saved you the trouble of making both by rolling them into one delicious dessert.

Trim edge, leaving a 1/2-inch overhang, then fold overhang under and crimp edge decoratively. Prick bottom and side of shell all over with a fork, then chill shell 30 minutes.

Line shell with foil and fill with pie weights, then bake until pastry is set and pale golden on rim, about 20 minutes. Carefully remove foil and weights and bake shell until pale golden all over, 6 to 10 minutes more.

                                Make pumpkin filling:
                                
                                
                                    
                                        - 
                                            
                                            
Whisk together pumpkin, brown sugar, egg, sour cream, cinnamon, nutmeg, and a pinch of salt in a bowl until smooth.
                                         
                                    
                                
                             
                        
                            
                                Make pecan layer:
                                
                                
                                    
                                        - 
                                            
                                            
Stir together corn syrup, brown sugar, eggs, butter, vanilla, zest, lemon juice, and salt in a bowl, then stir in pecans.
                                         
                                    
                                
                             
                        
                            
                                Assemble and bake pie:
                                
                                
                                    
                                        - 
                                            
                                            
Spread pumpkin mixture evenly in shell, then carefully spoon pecan mixture over it. Bake pie until crust is golden and filling is puffed, about 35 minutes. (Center will still be slightly wobbly; filling will set as it cools.) Cool completely on rack. Serve at room temperature.
                                         
                                    
                                
                             
                        
                    
                    Cooks’ note: Pie can be baked 4 hours ahead and kept, uncovered, at cool room temperature. Pie can also be baked 1 day ahead and chilled, loosely covered with plastic wrap. Reheat in a preheated 350°F oven until crust is crisp, about 15 minutes.
