Instructions

  1. Step 1: For crust: Pulse flour, sugar, and cold butter in a food processor until crumbly. Press mixture evenly into a 9-inch tart pan with removable bottom, then refrigerate for 30 minutes.
  2. Step 2: Preheat oven to 375°F (190°C). Bake crust for 15 minutes until golden. While baking, toss blueberries with lemon juice, zest, and cornstarch until evenly coated.
  3. Step 3: Remove tart shell from oven and fill with blueberry mixture, spreading evenly. Return to oven and bake for 35-40 minutes until filling bubbles around edges and crust is golden brown.
  4. Step 4: Cool completely on a wire rack. Dust with powdered sugar just before serving, using a fine-mesh sieve for even distribution. Let sit for 10 minutes to set before slicing.
