Thin-sliced potatoes and fragrant rosemary on pizza bianca is Roman comfort food. A vegetarian mediterranean pizza that's family-friendly and satisfying for a healthy dinner.
Preheat your oven to 475°F and place a pizza stone or heavy baking sheet inside to heat thoroughly.
Peel the potatoes and slice them as thinly as possible using a mandoline or sharp knife; soak the slices in cold water for 15 minutes to remove excess starch.
On a floured surface, stretch the pizza dough to a 12-inch round; transfer to a piece of parchment paper for easier handling.
Pat the potato slices dry, then toss them with 1 tbsp olive oil, half the kosher salt, and half the rosemary.
Brush the shaped dough with the remaining olive oil, sprinkle with black pepper, and layer the potato slices evenly, overlapping slightly; distribute mozzarella and the rest of the rosemary on top.
Carefully slide the pizza (still on the parchment) onto the preheated stone or baking sheet; bake for 13–17 minutes, until potatoes are just golden at edges and crust is crisp.
Finish with a final sprinkle of salt and pepper to taste after baking, then cool briefly before slicing and serving.
