Low carb Key lime pie with meringue crust

Meringue crust? Yes! It’s much lower carb than nut flours or any other low carb crust you can make. The meringue has a wonderful texture, especially with the macadamia nuts, and is the perfect backdrop for the tangy, but creamy key lime filling. You will need to make this a day ahead, but it's totally worth it!

Ingredients
  

meringue crust

  • 3 eggs white
  • 1/2 tsp cream of tartar
  • 1/8 tsp salt
  • 1/3 cup powdered extract
  • 1 tsp vanilla extract
  • 2 oz macadamia nuts, choppped

key lime filling

Instructions
 

Meringue crust

  • Preheat the oven to 300°F (150°C). Generously grease a 9” (23 cm) pie pan.
  • Whip the egg whites, cream of tartar and salt with a hand mixer until frothy.
  • Whip in the powdered sweetener and vanilla extract until stiff, glossy peaks form. Fold in the macadamia nuts.
  • Carefully spoon the whipped meringue into the pie pan. Be sure to push the meringue gently up the sides of the pan, creating a crust with the meringue.
  • Bake for 45 to 50 minutes or until the meringue is lightly browned and set. Set aside to cool.

Key lime filling

  • Melt the butter in a saucepan over low heat. Whisk in the powdered sweetener, Key lime juice, and lime zest. When the sweetener is dissolved, whisk in the egg yolks.
  • Keep the heat low and whisk constantly until the mixture has thickened. Remove from the heat and strain through a fine sieve to remove the zest. Refrigerate until cool, at least 1 hour.
  • In a separate large bowl, use a hand mixer or stand mixer to whip the heavy cream. As it begins to thicken, add the vanilla extract and continue whipping until the mixture is thick and creamy.
  • Gently fold the whipped cream mixture into the chilled lime juice mixture so that the filling remains fluffy.

Filling, chill and garnish

  • Use a spatula to fill the crust with the filling and smooth the filling edge to edge.
  • Place the pie in the refrigerator to chill for at least 4 hours or overnight before serving.
  • Garnish with lime slices, lime zest, and/or additional whipped cream, if desired.

Notes

Important!

You will need to make this a day ahead of time as the crust must cool before filling and the key lime filling needs time to set.
