Serves 4
3 tbsp (45 ml) butter
2 large cooking onions, peeled and thinly sliced
¼ tsp (1 ml) granulated sugar
salt and freshly ground pepper, to taste
1 cup (250 ml) thinly sliced new potatoes
4 tbsp (60 ml) olive oil, plus extra for brushing bread
2½ cups (625 ml) all-purpose flour
1 x 7 g package instant or quick-rise yeast
2 tbsp (30 ml) chopped fresh rosemary, divided
¼ cup (60 ml) finely chopped, pitted dried olives
½ tsp (2 ml) granulated sugar
¾ tsp (4 ml) salt
1 cup (250 ml) very warm water, about 130 F (50 C)
2 cups (500 ml) shredded fontina cheese
6 slices pancetta, ⅛ -in (0.25 cm) sliced, cooked until crisp, and crumbled
½ cup (125 ml) crumbled feta cheese
1 tbsp (15 ml) fresh thyme leaves


  1. To make caramelized onions, melt butter in large frying pan over medium heat. Add onions and sugar and toss to coat. Slowly cook onions, stirring occasionally, for 15 to 20 minutes or until they start to turn colour. Turn heat up to mediumhigh and stir constantly until they begin to brown, about 10 more minutes. Season with salt and pepper. Set aside to cool.
  2. Preheat oven to 400 F (200 C). Line a baking sheet with parchment paper or foil. In a bowl, toss potatoes with 2 tbsp (30 ml) olive oil and season with salt and pepper. Lay in a single layer on the baking sheet. Place in oven and bake, turning slices over once, until potatoes just begin to brown, about 10 to12 minutes. Remove from heat and cool.
  3. In a large mixing bowl, add 2 cups (500 ml) flour, yeast, 1 tbsp (15 ml) of the rosemary, chopped dried olives, sugar and salt. Gradually stir the warm water and 2 tbsp (30 ml) olive oil into the flour mixture with a wooden spoon. Stir in enough remaining flour to make a soft dough. Knead on lightly floured surface until smooth and elastic, about 5 to 10 minutes. Cover and let rest on floured surface 10 minutes. Alternatively, this can be done in an electric mixer with a dough hook attachment.
  4. Preheat barbecue to 450 F (230 C).
  5. Roll or press dough into a 12- or 16-in (30 to 40 cm) circle. Spray lightly or brush with vegetable oil spray or olive oil and allow dough to sit 10 minutes while barbecue preheats.
  6. When barbecue is hot, place flatbread dough, oiled-side down, on grill and cook, covered, 3 to 7 minutes or until underside has grill marks, is lightly browned and the top has started to bubble. Watching to make sure temperature is not too high, as all barbecues are different.
  7. Spray top with vegetable oil spray or brush with olive oil, flip flatbread over and grill other side 3 to 4 minutes until very lightly browned. Remove flatbread dough from barbecue and transfer to a large wooden board or platter. Lightly brush perimeter of the dough with olive oil. Sprinkle about two-thirds of the shredded fontina over dough. Layer evenly with cooked potato slices, caramelized onions and crumbled pancetta. Sprinkle with feta, remaining fontina and rosemary.
  8. Return flatbread to barbecue, reduce heat to medium and cook another 3 to 5 minutes, or until cheeses have melted. Remove from grill and sprinkle with thyme. Let cool slightly before slicing and serving.
