Roman-Style Crispy Thin Crust (Pizza Tonda Romana)
An ultra-thin, cracker-like dough that skips the puffy edges entirely. Low hydration and olive oil create a sturdy, shatteringly crisp crust perfectly suited for slower baking temperatures.
Ingredients
The Method
In a small bowl, combine the warm water and the active dry yeast. Stir gently and let it sit for about 5 to 10 minutes until it becomes frothy and blooms.
Chef's Secret
Warm water (about 85°F to 105°F maximum) activates the yeast cells out of dormancy. If the water is too hot (above 115°F), you risk killing the yeast entirely; if too cold, the yeast will activate sluggishly or not at all before baking.
In a large mixing bowl or the bowl of a stand mixer, whisk the flour and the fine sea salt together to distribute the salt evenly.
The Science
We use a comparatively low 'hydration' for Roman dough (about 54% water to flour weight) intentionally. Less water means less steam is generated during the bake. Without steam to push the dough upward, the crust bakes completely flat, dense, and exceptionally crispy—the defining trait of a true Roman 'Tonda'.
Make a well in the center of the flour mixture and pour in the frothy yeast water along with the extra virgin olive oil.
The Science
Notice the high amount of oil (fat) in this recipe compared to Neapolitan doughs (which use zero oil). The oil 'shortens' the gluten strands by literally coating the flour proteins. These shorter strands snap rather than stretch when bitten, resulting in a true cracker-like shatter and flakiness.
Mix the ingredients together using a wooden spoon or your hands until a shaggy dough forms. Turn it out onto a lightly floured surface and gently knead for about 5 to 7 minutes until the dough feels cohesive, smooth, and no longer exceptionally sticky.
Chef's Secret
Because of the low hydration and high oil content, this dough will feel much stiffer than traditional pizza doughs. Knead until smooth, but do not obsess over passing a 'windowpane test' as extreme gluten development is counterproductive to a crisp, tender bite here.
Divide the kneaded dough into two equal portions (roughly 280g each). Round them into reasonably tight balls. Place them on a thoroughly oiled baking sheet, brush the tops generously with more olive oil, and cover loosely with plastic wrap.
Chef's Secret
Brushing the tops heavily with oil prevents a dry 'skin' or crust from forming during the room temperature rise, which would interfere with rolling them out thinly.
Let the dough balls rest and rise at room temperature for 2 to 3 hours until they have roughly doubled in volume and are relaxed to the touch. In the final 45 minutes of the rise, strictly preheat your home oven to 500°F (or its maximum setting), ideally with a heavy baking steel or pizza stone placed on the lowest rack.
Crucial Step: Do not handle the dough gently to preserve air bubbles like you would Neapolitan dough; we want zero puff. Turn a fully rested dough ball onto a floured surface. Dust the top with more flour. Using a heavy wooden rolling pin, aggressively roll the dough out into an impossibly thin circle, about 1-2 mm thick and 12-14 inches wide.
The Science
Using a rolling pin permanently degasses the dough by forcibly crushing out all carbon dioxide bubbles accumulated during fermentation. This mechanical 'destruction' of the crumb guarantees that no thick rim (cornicione) inflates when exposed to oven heat.
Transfer the ultra-thin crust immediately to a very well-floured pizza peel or an inverted sheet pan. The dough must slide freely; if not, add more flour underneath. Work incredibly fast: spread a thin, scant layer of sauce edge-to-edge (leave absolutely no bare dough crust), sprinkle cheese sparingly, and immediately slide it onto the preheated stone or steel.
Chef's Secret
Roman pizza ('scrocchiarella', meaning crunchy) relies on sauce reaching the absolute edges. Any bare dough an inch thick around the perimeter will rapidly burn and turn into a solid, inedible biscuit in the oven.
Bake for 12 to 15 minutes. The bottom should be deeply browned and completely rigid when lifted with a spatula, and the cheese should be fully melted and slightly caramelized. Slice and serve immediately.
