Lemon Ice Box Pie Recipe

Pie IS nostalgia. And this particular Lemon Icebox Pie represents my own personal stroll down memory lane, complete with sighs and happy feelings.

There’s just something about a creamy, dense lemon filling topped with sour cream, settled on top of a graham cracker crust. It’s one of those old-fashioned desserts that takes you back in time. It makes your cheeks pucker and your eyes roll with pleasure.

Lemon Icebox Pie Is Always on the Menu

Lemon Icebox Pie was one of the first desserts on our menu at the tiny restaurant I started with friends in upstate New York. The restaurant expanded, and a chef—actually a friendly neighbor with a summer house nearby (a weekend retreat from his fancy French restaurant in New York City)—became my mentor.

Our offerings became more and more sophisticated and European. But despite the European influence, we kept some old-fashioned American favorites by popular demand. Lemon icebox pie became one of our signature desserts.

How to Make Lemon Icebox Pie

The pie itself takes under 25 minutes to put together, which is not bad in "pie time." First, make the graham cracker crust (15 minutes, here's the recipe), then make the filling (10 minutes). Baking and chilling take longer, so you’ll want to make this pie early in the day you want to serve it—or even better, the night before.

Once the pie is filled, baked and chilled, spread a layer of barely sweetened sour cream on top to give the pie a tangy counterpoint to all the filling’s lemony sweetness. The pie needs to go into the oven for 10 minutes once you add the sour cream, just to set the cream. Then it needs another turn in the fridge to completely chill again.

This is a quintessential summer pie, one you can imagine that your grandmother or great grandmother would make. Put this on the top of your “pies to-make” list and grab a slice of nostalgia.
