How to prepare Radicchio and Potato Savory Tart

To prepare the radicchio and potato savory tart, start with the potatoes: immerse them in cold water and cook for about 30 minutes from the boil, or until tender 1. In the meantime, wash the late-season radicchio, remove the base and cut it into strips 2. Heat a drizzle of olive oil in a pan 3.

Add the radicchio 4 and season with salt 5. Cook over medium heat for about 8 minutes 6 or until soft.

Let it cool and set aside 7. In a bowl, mash the cooked potatoes with the skin on while still hot 8, then add the eggs 9.

Season with grated Parmigiano Reggiano 10, salt, pepper 11 and the chopped walnuts 12.

Fold in the stewed radicchio 13 and mix well until you obtain a homogeneous mixture 14. Unroll the puff pastry and line an 8 2/3-inch (22 cm) pan with it, leaving the parchment on the bottom. Prick the base with a fork so it won't puff up during baking 15.

Pour the filling inside 16 and level the surface 17. Use a vegetable peeler to shave thin slices of fontina 18.

Fold the edges of the pastry inward 19, then beat the egg and brush the rim of the pastry 21.

Bake in a preheated conventional oven at 356F for about 40 minutes 22, until the surface is golden 23. Let rest a few minutes before slicing and serving your radicchio and potato savory tart 24!
