Key Lime Pie Recipe

There is something wonderfully simple about a Key lime pie: a crisp, buttery graham cracker crust holding a smooth, tart filling made from just sweetened condensed milk, egg yolks, and lime juice. This version is easy enough for a weeknight dessert, but it has the kind of clean, bright flavor that makes it especially welcome after a heavier meal. The filling sets in the oven rather than relying on gelatin, so each slice has a tender, creamy texture that is firm enough to cut neatly without feeling stiff. Start by crushing the graham crackers very finely; larger crumbs can make the crust crumble when you slice it. Mix them thoroughly with melted butter and sugar, then press the mixture firmly across the bottom and slightly up the sides of a pie dish. I use the flat bottom of a measuring cup to compact it evenly, especially around the edge. Bake the crust for a few minutes before adding the filling. That short bake gives it a toasted flavor and helps it stay crisp beneath the soft lime layer. For the filling, whisk the egg yolks until smooth, then stir in the sweetened condensed milk and key lime juice. The mixture will gradually thicken as the acidic juice reacts with the dairy, but it should still look glossy and pourable when it goes into the crust. Key lime juice has a distinctive floral sharpness, though bottled key lime juice works very well when fresh key limes are unavailable. The most important practical tip is not to overbake: remove the pie when the center still has a slight wobble. It will continue setting as it cools, and chilling it thoroughly—at least a couple of hours—gives you the cleanest slices. Serve it cold, topped with softly whipped cream rather than a thick, overly sweet layer. The cream rounds out the lime’s tang while leaving the graham cracker and custard flavors clear. This is a natural finish for a grilled dinner, seafood supper, or summer barbecue, and it pairs nicely with strong coffee, iced tea, or a small glass of sparkling wine. For the best texture, add the whipped cream just before serving and run your knife under hot water, then dry it, between slices.
