Lemony Sweet Potato Pie

Most sweet potato pies lean into warm spices like cinnamon and nutmeg. This one goes a completely different direction with lemon. Lemon extract and grated lemon zest mixed into the mashed sweet potato filling create a custard that’s bright and citrusy instead of heavy and spiced.

The filling is more custard-like than dense: egg yolks, sugar, a tablespoon of flour, and 1 ½ cups of milk beaten with the mashed sweet potatoes and butter. It bakes up silky and smooth rather than thick and starchy, closer to a chess pie in texture than a typical Thanksgiving sweet potato pie.

The two-temperature bake is important. A blast at high heat sets the crust and starts firming the filling, then the lower temperature lets the custard cook through gently without cracking or curdling.

Pro Tips

• Use freshly cooked and mashed sweet potatoes, not canned; the flavor and texture are noticeably better
• Beat the filling until very smooth; lumps of potato won’t disappear during baking
• The pie is done when the center is firm but still has a slight jiggle; it sets fully as it cools
• Serve warm with cold sweetened whipped cream for the temperature contrast

Variations

• Add a pinch of nutmeg alongside the lemon for a more complex flavor
• Top with a meringue made from the leftover egg whites instead of whipped cream
• Use a graham cracker crust for a sweeter, crunchier base
