How to Make Blueberry Key Lime Tart

  1. Preheat oven to 375°F (190°C). Prepare your pie crust (recipe not included, but highly recommended!). Press the dough into a 9-inch tart pan.
  2. Blind bake the crust: Line the crust with parchment paper and fill with pie weights or dried beans. Bake for 15 minutes. Remove the weights and parchment and bake for another 5 minutes, until lightly golden.
  3. Meanwhile, prepare the key lime filling: Whisk together the key lime juice, zest, sugar, eggs, and cornstarch in a medium bowl until smooth.
  4. Pour the key lime filling into the pre-baked tart shell.
  5. Bake for 20-25 minutes, or until the filling is set. Let cool completely on a wire rack (this will take about 1 hour).
  6. Just before serving, prepare the blueberry topping: In a small bowl, gently toss the blueberries with the sugar and cornstarch.
  7. Spoon the blueberry topping evenly over the cooled key lime filling. You can also add a dollop of whipped cream or a sprinkle of lime zest for garnish.
  8. Refrigerate for at least 30 minutes before serving to allow the flavors to meld.
