This dessert recipe for key lime pie from our cookbook, Cooking Well, is low in sodium and protein.



  • 1 1/2 cups graham crackers, crushed
  • 1/4 cup sugar
  • 5 tablespoons unsalted butter, melted


  • 1 can (14 ounces) nonfat, sweetened, condensed milk
  • 1/2 cup fresh lime juice
  • 1 tablespoon lime zest, minced
  • 1 large egg
  • 2 large eggs, separate yolks and whites
  • 1/4 teaspoon cream of tartar
  • 2 cups low-calorie whipped cream (such as Cool Whip)
  • 1 lime, thinly sliced (optional)

Cooking instructions

  1. Preheat oven to 325°F.
  2. For the crust: Mix graham cracker crumbs with sugar and butter. Spread evenly over the bottom and sides of a nonstick 9-inch pie pan, and bake for 5 minutes. Remove from oven; let cool.
  3. For the filling: In a medium bowl, using a fork, beat milk, lime juice, and zest. Add 1 whole egg and 2 egg yolks (reserve whites) and beat well. Set aside.
  4. In a large mixing bowl, beat egg whites until foamy. After about 20 seconds, add cream of tartar. Fold whites into the custard mixture and pour into partially baked crust.
