Here’s an interesting twist on focaccia.

There’s no flour in this potato & onion focaccia from the southwestern region of Puglia, focaccia di patate e cipolle in Italian.

The “dough” is fashioned from riced potatoes with grated parmigiano and white wine.

The potato dough holds a sweet filling of long-cooked onions with capers and black olives.

The focaccia is topped with bread crumbs and baked in the oven until golden brown.

The creamy potato crust top and bottom has a nutty crunch as you bite into the perky sweet onion filling with the capers and olives.

Serve the focaccia as a side for meat or fish or incorporate it into your next antipasti platter.

Buon appetito!
