How To Order Shake Shack's Smoky Secret Menu Mushroom Burger

We love a secret menu. Who doesn't, right? There's something exciting about ordering an under-the-radar, off-the-menu creation at any eatery. Not only do you get to bite into something truly unique, but you feel like you're part of a club — a secret, delicious club.

Shake Shack may have humble beginnings as a hot dog stand in Madison Square Park, but today, it's beloved for its burgers. With locations throughout the United States, it's grown into one of America's most popular fast casual spots for burgers, fries, hot dogs, and shakes, striking that masterful balance of fast-food-meets-gourmet with their decadent creations and nostalgic menu.

Like most fast food joints, there's a secret menu floating around the internet, offering Shake Shack creations you've never heard of. But one secret menu item isn't so secret anymore, thanks to a "Shack Hack" TikTok video from Shake Shack themselves. Meet the Smoke 'Shroom, which you can order with nothing more than a few swipes on a tablet.

The Smoke 'Shroom is a cross-over between Shake Shack's 'Shroom Burger – a crispy, deep-fried Portobello mushroom stuffed with melty muenster and cheddar cheese – and their signature SmokeShack, which is an Angus beef patty with cheddar cheese, applewood-smoked bacon, and cherry peppers.

If you like mushrooms, gooey cheese, smoke, and spice, this one's for you. Creating it is super easy, as Shake Shack demonstrates in their TikTok video. To order the Smoke 'Shroom, you simply order the 'Shroom Burger and remove the lettuce and tomato, then add on the bacon and cherry peppers that you'd normally find on the SmokeShack. Both burgers come with Shack Sauce on a toasted potato bun; the only thing you need to modify is those few toppings. In the end, you have a smoky, mushroom-y, deeply flavorful burger that's got a bit of a kick and a whole lot of melted cheese.

There are more secret menu items where the Smoke 'Shroom came from, and Shake Shack is continually adding new creations to the list. While some items are par for the course, like the grilled cheese and a "protein style" burger, there are other more surprising meals available as well, which just might knock your socks off.

One of Shake Shack's most notable secret menu items is the peanut butter and bacon Shackburger, which is the bacon Shackburger ordered with a slathering of peanut sauce. You can also take cheese fries to the next level by ordering chili pepper cheese fries, which come with spicy chili peppers mixed into melted cheese over Shake Shack's signature crinkle-cut fries. And while you're at it, why not pair those with a refreshing Shake Shack shandy?

For the sweet tooth crew out there, the ice cream sandwich can't be missed. This isn't your usual ice cream sandwich, squished between two cookies — it's an order of Shake Shack's frozen custard with a side of toasted potato buns, creating the ultimate dessert. What a great way to end a meal filled with secret menu items!
