National Cheeseburger Day

If there’s one day on the calendar that feels made for us, it’s the National Cheeseburger Day. Afterall, we’ve been putting our spin on the great American cheeseburger since 2004 with the ShackBurger

And what’s a better way to celebrate than with extra beef? From 14 – 18 September, celebrate National CheeseBurger day with a FREE Beef Patty add-on* with any ShackBurger or SmokeShack purchase via the Happy Point app.

The Cheeseburger Formula

The cheeseburger has earned its place as an American classic with a simple formula: beef, cheese, bun and toppings. But when something is made up of just a few ingredients, every one of them matters. So, what makes a great cheeseburger? Let’s break down the basics.

Real Beef

For us, a good cheeseburger starts with the beef. That’s why our beef patties are made to order with 100% Angus beef. Each quarter-pound beef patty is smashed to order, seasoned, seared and cheesed to bring together the rich, beefy flavor and juicy texture that fans know and love.

Real Classic

We believe in keeping good things simple. So when it came to our version of the great American cheeseburger, reinvention wasn’t really on the agenda. Getting it right was.

While it sounds simple, getting simple right actually took years of tinkering, tweaking and plenty of tasting before we landed on the ShackBurger, a classic in its own right that continues to let the beef speak for itself.

Now that you know the beef, come taste it for yourself!
