Part 2/6:
The foundation of this beloved soup starts with simple ingredients: olive oil, onions, and ground beef. The process begins by heating olive oil in a pot and browning chopped onions alongside ground beef until both are tender and flavorful. This step creates a savory layer that builds the depth of the soup, and for added richness, some cooks prefer using beef short ribs; however, ground beef works perfectly for a more accessible and quicker option.
