Fugazzeta Rellena is the stuffed onion bread of Buenos Aires, a thick double-crusted disc of pizza dough packed with mozzarella and crowned with a heavy layer of sweet onion. It sits in the catalog as a sandwich because that is how it is eaten: a wedge cut from the round, the top crust and bottom crust holding a molten cheese filling between them, picked up by hand like any other bread-and-filling assembly. The angle is the ratio of three things, dough, cheese, and onion, none of which can dominate. Get it right and a slice pulls a long string of cheese while the onions stay soft and sweet on top; get it wrong and it is either a dry bread shell or a greasy slab that slides apart in the hand.
The build is specific and unforgiving. Two layers of leavened pizza dough are pressed into a deep pan, the bottom one thicker to carry the load. A generous quantity of mozzarella goes in between, sometimes with a little provolone for sharpness, then the second sheet of dough is laid over and sealed at the edges so the cheese cannot escape. The whole thing is baked until the crust is set and golden. The onions are the signature: thin-sliced, salted, often pressed to draw out water so they do not steam the bread, then spread thick across the top and baked or scattered on near the end so they soften without burning. Good execution shows in the cross-section. The crumb is open but sturdy, the cheese layer is continuous rather than pooled in one spot, and the onions are jammy and faintly sweet, not raw and not scorched. A drizzle of olive oil and a dusting of oregano finish it. Sloppy execution is a thin underbaked center where the cheese has wept into a puddle, a top crust with no onion to speak of, or onions burnt black at the edges of the pan.
It varies mostly by what joins the cheese inside and how the onion is treated. The plain fugazza, onion bread with no cheese filling, is the leaner ancestor of this form and reads as a different sandwich entirely: bread and onion, no molten core. Add ham to the cheese layer and it becomes a heavier, saltier build closer to a baked sandwich than a pizza. Some bakeries fold sliced tomato or roasted red pepper into the filling, which brightens the whole thing and cuts the richness. The defining variable stays the same across all of them, whether the onion on top is soft and sweet enough to balance the weight of the cheese underneath it. Among the pan-and-empanada style breads of the city, this is the one judged almost entirely on that single contrast.
