Prepare the Potatoes: Slice the potatoes very thinly. If using new potatoes, you can leave the skins on; otherwise, peel them if desired. Soak the slices in a bowl of cold water for 20 minutes, changing the water once during this time.
14 oz potatoes
Make the Batter: In a mixing bowl, combine the flour, grated Parmesan, and a pinch of salt. Gradually add the water, stirring until you achieve a smooth batter.
1 1/2 cups all-purpose flour, 1/4 cup grated Parmesan cheese, Salt, 1 1/3 cups water
Incorporate Ingredients: Mix in the olive oil until well combined. Drain the potato slices thoroughly, then add them to the batter along with some chopped fresh rosemary. Stir to ensure the potatoes are evenly coated.
1/4 cup olive oil, Fresh rosemary
Prepare the Baking Pan: Line a large rectangular baking pan with parchment paper and lightly grease it with olive oil. Pour the potato mixture into the pan, spreading it out evenly with a spatula.
Add Toppings: Decorate the top with a few reserved potato slices, a sprinkle of rosemary, a drizzle of olive oil, and a pinch of salt and pepper.

Bake: Preheat your oven to 350°F (175°C) for a conventional oven or 340°F (170°C) for a convection oven. Bake for about 30 minutes, or until the flatbread is golden and crispy.
Serve: Remove from the oven, cut into squares, and serve hot. It's perfect on its own or paired with deli meats, cheeses, or grilled vegetables for a vegetarian option.
