Step 1 of 5

Mix and shape the patties

Mix the ground beef with the breadcrumbs, the beaten egg, the grated half of the onion, half the Worcestershire sauce, the Dijon, the salt and the pepper. Shape into four oval patties, thicker than a burger.

— Grate the onion for the mix rather than chopping it. The juice goes into the meat and there is nothing left to stay crunchy.
