  • 1 (14-ounce) can sweetened condensed milk
  • 1/2 cup fresh key lime juice (from about 10-12 key limes)
  • 4 large egg yolks
  • 1 tablespoon key lime zest (from about 2-3 key limes)
  • 1 (9-inch) pre-baked graham cracker crust

Method
 

  1. Preheat your oven to 350°F (175°C). Ensure your graham cracker crust is ready and set aside.

  2. In a medium bowl, whisk together the sweetened condensed milk and fresh key lime juice until well combined. The mixture will begin to thicken slightly.

  3. Add the egg yolks to the sweetened condensed milk and key lime juice mixture, one at a time, whisking thoroughly after each addition. Continue to whisk until the filling is smooth and homogenous.

  4. Gently stir in the key lime zest. This will infuse the pie with an extra burst of fragrant lime flavor and aroma.

  5. Pour the prepared filling evenly into the pre-baked graham cracker crust. Ensure the filling reaches all the edges of the crust.

  6. Carefully place the pie in the preheated oven. Bake for 15-18 minutes, or until the center of the pie is just set but still has a slight wobble. Overbaking will result in a less creamy texture.
  7. Remove the pie from the oven and let it cool completely on a wire rack for at least 1 hour. This allows the filling to fully set and develop its characteristic creamy consistency.
  8. Once cooled, cover the pie loosely with plastic wrap and refrigerate for at least 3-4 hours, or preferably overnight, before slicing and serving. Chilling is crucial for achieving the perfect texture.

Notes

To keep your Best Southern Key Lime Pie tasting as fresh as possible, proper storage is key. Cover the pie tightly with plastic wrap and refrigerate immediately after it has cooled. It will stay delightfully fresh in the refrigerator for up to 3-4 days. Freezing is also an option, though it may slightly alter the texture of the filling. To freeze, ensure the pie is completely chilled, then wrap it very tightly in several layers of plastic wrap, followed by a layer of aluminum foil. Frozen pie can be kept for up to 1 month. When you're ready to enjoy a slice, if refrigerated, serve it cold straight from the fridge. If the pie has been frozen, allow it to thaw in the refrigerator overnight before serving. There’s generally no need to reheat this pie; its true magic lies in its cool, refreshing consistency. If you find the crust slightly softened after freezing and thawing, a brief, gentle warming in a low oven (around 250°F or 120°C) for about 5-10 minutes can sometimes help crisp it up, but this is optional and not typically necessary for optimal enjoyment.
