Just Burgers’ core burger starts with a one-fifth–pound smashed beef patty, caramelized onions, lettuce, tomato, and house sauce on a toasted bun. The menu specifically notes the smash preparation and emphasizes the role of sauces and toppings in delivering the intended flavor and texture. When eaten as designed, the burger offers crisp, seared edges on the patty, sweetness from the onions, and a saucy, juicy interior that the toasted bun helps contain. The University District shop bills itself as a handcrafted burger spot, and its smash-style patty is central to that identity.
