🍳 Step-by-Step Instructions

  1. Preheat oven to 175°C (350°F).
  2. Mix graham cracker crumbs, melted butter, sugar, and salt. Press firmly into bottom and up sides of a 23 cm (9-inch) pie dish. Bake for 10 minutes; set aside to cool.
  3. In a bowl, beat egg yolks and lime zest with an electric mixer for 2 minutes until pale and thick.
  4. Pour in sweetened condensed milk and beat 2 minutes more.
  5. Stir in key lime juice; the natural acid will thicken the mixture immediately.
  6. Pour filling into pre-baked crust.
  7. Bake for 14-16 minutes until filling is set and only slightly jiggles in center.
  8. Cool on wire rack for 1 hour, then refrigerate for at least 4 hours (or overnight) until completely chilled.
  9. Whip heavy cream and powdered sugar to medium peaks. Pipe or spread over cold pie, garnish with lime slices and zest, and serve.

👨‍🍳 Chef's Essential Tips

  • Fresh key lime juice has a distinctive floral aroma, but standard fresh Persian limes make a delicious pie as well
  • Do not skip baking; a brief 15-minute bake sets the egg yolks safely without browning the custard
  • Chill for at least 4 hours before slicing so it cuts into clean, photogenic wedges

⭐ Why This Recipe Works

  • Sensational balance of intense sweet cream and tart citrus
  • Only 3 filling ingredients make it almost foolproof
  • Crunchy, buttery graham cracker crust holds up well
  • Refreshing, chilled summer dessert

🔄 Delicious Variations

  • Frozen Key Lime Pie: Freeze pie and serve semi-frozen like an ice cream pie
  • Coconut Key Lime: Add toasted coconut to the crust and whipped cream
  • Gingersnap Crust: Swap graham crackers for crushed spicy gingersnap cookies

❓ Frequently Asked Questions

Is authentic key lime pie green?
No! Real key lime pie is naturally pale yellow from the egg yolks and condensed milk. Green pie has artificial food coloring.
Can I use bottled lime juice?
Fresh lime juice is far superior in flavor, though bottled Nellie & Joe's Key West Lime Juice is a respected classic.
