Schiacciata and focaccia are both Italian flatbreads, but they have some differences. Schiacciata is typically thinner and lighter than focaccia, with a texture that is often more airy and delicate. It is commonly seasoned with olive oil, salt, and sometimes herbs like rosemary or sage. Focaccia, on the other hand, tends to be thicker and more substantial, with a chewier texture. It is often topped with olive oil, salt, and various ingredients such as olives, tomatoes, onions, or cheese.
