While most lemon tart recipes feature butter in both the crust and the filling, in this recipe we use extra-virgin olive oil to take some of the fuss out of your prep work.
Simply mix flour, sugar and salt with the oil and a little water until a soft dough forms; crumble it into the tart pan; press it into the sides and bottom; and bake it right away. There’s no rolling or chilling required!
Using olive oil in the filling as well allows the lemons’ acidity to shine through, allowing you to use a bit less juice than you’d need to enjoy the bright flavor if you had used butter instead. You also won’t lose any of the firmness or sliceability you’d expect in a tart, because the filling gets plenty of structure from the protein in the eggs….
