Place the pizza dough with baking paper on a baking tray. Let dough rest for about 10 minutes. Wash the rosemary, shake dry and pluck the needles. Cut the potatoes into slices. Halve the bacon slices.
Heat the oil in a pan. Leave the bacon slices out for approx. 3 minutes while turning (do not fry until crisp). Drain on kitchen paper. Season sour cream with salt and pepper to taste and spread it on the pizza dough.
Spread potato and bacon slices on top and sprinkle with rosemary needles. Sprinkle with some coarse salt and pepper. Bake the pizza in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 10-12 minutes.
