Method

Prepare the Tart Crust

  1. 1

    Make the Dough

    In a large bowl, combine flour and salt. Cut in cold butter until mixture resembles coarse crumbs. Gradually add cold water, mixing until a dough forms. Wrap in plastic wrap and refrigerate for at least 30 minutes.

  2. 2

    Blind Bake the Crust

    Preheat the oven to 375°F (190°C). Roll out the chilled dough and fit into a tart pan. Prick the bottom with a fork and bake for 15 minutes. Remove from oven and let cool.

Prepare the Onion Filling

  1. 3

    Cook the Onions

    In a skillet, heat olive oil over medium heat. Add sliced onions, thyme, salt, and pepper. Cook, stirring often, until onions are caramelized and soft, about 20 minutes.

Assemble and Bake

  1. 4

    Assemble the Tart

    Spread the caramelized onions evenly over the cooled tart crust. Arrange the sliced bluefin tuna on top, followed by the black olives.

  2. 5

    Final Bake

    Bake the tart in the oven for an additional 10-15 minutes until warmed through. Remove from oven and garnish with fresh parsley and lemon zest before serving.
