French Lemon Pie

This is the French country cousin of American lemon meringue pie, a plain-Jane tart with no meringue, no cornstarch, no fuss. The filling relies on the classic French trio of butter, lemon, and sugar enriched with a single egg for a custard that’s lighter than a tart au citron and richer than a curd.

The whole-wheat crust is the clever touch. Its nutty edge balances the bright citrus filling and provides the earthy backbone that makes the pie feel unfussy and rustic. A food processor crust comes together in 30 seconds, don’t overwork it or the butter melts and the crust turns tough.

Use the zest from the whole lemon, not just what comes off easily. The yellow outer peel carries the oils that make the filling sing. Avoid the bitter white pith underneath.

A high 425°F (220°C) oven sets the filling fast and gives the crust a proper bake without the top overcooking. The pie should wobble slightly in the center when done, it sets fully as it cools.

Pro Tips

• Warm the egg, melted butter, and lemon juice to room temperature before mixing, cold ingredients curdle when whisked together.
• Press the crust firmly into the pan with the back of a spoon for even thickness.
• Cool fully before slicing, at least 2 hours. Warm pie runs when cut.
• Serve with a dollop of unsweetened whipped cream or crème fraîche to cut the richness.

Variations

• Swap half the lemon juice for Meyer lemon or a mix of lemon and orange for a softer flavor.
• Add a tablespoon of fresh thyme leaves to the filling for a herbal twist.
• Top with fresh raspberries or candied lemon peel for a prettier presentation.
