The Maillard Reaction And Smash Burger Revival
Food trends move at incredible speed – but even so, the rise of the smash burger has been remarkable. Less than a year ago, this style – essentially, burgers rendered as wider, flatter, crispier patties, for maximum flavour – was a fairly niche concern.
Last winter, that all changed. In Soho, a new takeaway called Supernova generated queues that led GQ magazine to declare: “The smash burger has officially eaten London.”
The resurgence in smash burger popularity is primarily driven by a unique cooking technique that maximizes the Maillard reaction, responsible for the browned, complex flavors that make bread taste toasty and malty, burgers taste charred, and coffee taste dark and robust.
The important thing about the Maillard reaction, however, isn’t the color, it’s the flavors and aromas. Indeed, it should be called “the flavor reaction,” not the “browning reaction.” The molecules it produces provide the potent aromas responsible for the characteristic smells of roasting, baking, and frying.
Instead of grilling pre-formed burger patties, smash burgers are balls of ground beef that are placed on a furiously hot flat-plate grill and, to produce a pronounced sear, firmly smashed or pressed into thinner, wider-diameter patties, using a metal burger press or heavy spatula. According to one of the smash burger’s many origin stories, the original implement was a can of beans.
The increased surface area allows for maximum contact with the heat and causes a chemical reaction (the Maillard reaction) that creates a flavorful, crispy, caramelized crust on the exterior while sealing in the juices, a texture and taste traditional, thick burgers often lack.
The contrast between the crispy, lacy edges and the juicy, tender interior provides a satisfying textural experience in every bite, and the thin patties serve as an ideal base for creative and customizable toppings, sauces, and buns, allowing for endless flavor combinations that keep menus fresh and exciting.
The visual appeal of smash burgers—with their irregular, lacy edges and gooey melted cheese—makes them highly photogenic and shareable online, further amplifying their popularity through food bloggers and influencers.
Smash burgers also evoke a sense of nostalgia for classic, old-school diner culture and simple, honest food. This comfort food aspect resonates strongly with today's consumers seeking familiarity and a sense of discovery in their dining experiences.
