Shack Shack Secret Menu

The Shack Shack has a classic retro vibe of a 1950’s American Diner but the truth is that it started in July 2004 as a hot dog cart in Madison Square Park. The cart was a daily thing during New York summers and they had long lines for three summers according to the Shake Shack website.

Shake Shack Secret Menu Items You Need to Know About!

“Shake Shack is just an ordinary fast-food joint,” said nobody ever. Shake Shack takes the cake for gourmet fast food classics, offering a modern-day take on retro roadside burgers, fries, hot dogs, frozen custards, shakes, and more. There’s the traditional fast food chain, and then there’s Shake Shack. The two are incomparable; I’m talking completely different hemispheres here. Though all the classic cult-favorites are fabulous, I’m here to share the Shake Shack secret menu items that will blow your expectations out of the water.

From a decadent root beer float to an astonishingly simple grilled cheese, these are all must-tries to add to your foodie bucket list.

Shake Shack Secret Menu Burgers

Protein-Style Burger

If you are eating low carb, or keto or just trying to find something that seems slightly “healthier” on the Shake Shack menu, the protein style burger is a great option.

It is simply the ShackBurger without the delicious potato buns. Because potatoes and buns have a lot of carbs, this eliminates those. And then like they do on the In-n-Out Secret Menu, they will use butter lettuce as the “bun” and you get to enjoy the burger with a lot fewer carbs and calories too!

To order – ask for a ShackBurger without a bun. Shake Shack will make ANY burger with a lettuce wrap.

Shake Shack Quad Cheeseburger

If you love the regular awesome ShackBurger, what could be better than 4 times the meat?

To order- order any of the burgers with 4 beef patties.

Note: This is basically the same as the 4×4 burger on the In-n-Out Secret Menu.

Peanut Butter Bacon Cheeseburger

This is for all the people who like low calorie, low fat food.

LOL…just kidding! If you love bacon cheeseburgers, why not make it a little more intense with a drizzle of peanut sauce on top of your burger.

To order – order a bacon ShackBurger and ask for a side of peanut sauce to pour over the burger.

Note: Shack Shack recently removed all peanut products from their menu due to allergy issues. We have a hunch this item will return at some point, so we are leaving it up here just as an FYI.

By themselves, the Shake Shack cheese fries are a fan favorite. But if you want to take them to the next secret menu item level try drizzling the extremely tasty Shake Shack Shack Sauce over them for an impressive flavor boost!

This sauce is a Spicy-Sweet-Sour Mayo Blend sauce that includes mayo, ketchup, mustard, and spices. While the actual recipe is a secret, Bon Appetit thinks it is a combination of mayo, dijon mustard, ketchup, dill pickle brine and cayenne pepper. It complements the cheesy flavor without being too overpowering.

To order – just order cheese fries with a side of the Shack Sauce.

Shake Shack Secret Menu Sandwiches (Not Burgers!)

Grilled Cheese

This is shake Shack’s transformation of a childhood favorite into a secret menu item! They grill the already delicious potato hamburger buns inside out until they are golden and crispy, add cheese and bam – a lovely grilled cheese sandwich that kids of all ages will enjoy! It is super buttery, and super cheesy.

To order – just asked for the Grilled Cheese.

Shack-Cago Dog

This hot dog variation has achieved cult status. At first we didn’t “get” the name – do you? It’s their tribute to Chicago and a Chicago style hot dog!

We have to admit we aren’t so excited about it but if you love hot dogs at Shake Shack, and want to try something new, it’s worth a try!

To order – ask for the Cago Cog and they will top the regular hot dog with onions, pickles, peppers, onions tomatoes and cucumbers and even a little celery salt!

In short, it’s an easy and free way to feel like you are eating healthier with a ton of veggies on your hot dog!

And important note: this is essentially a recreation of a traditional “Chicago style” hot dog. And one of the rules is NO KETCHUP. Ever.

The Garden Dog

Okay this is an amazing option for vegetarians. Most people don’t know about this option.

A “Garden Dog” is basically the Shack-cago Dog we just described but it’s all vegetarian. Instead of a hot dog as the base, they use a large pickle!

If you are vegetarian and want to eat with your friends at the Shake Shack this is a good option.

To order- ask for the  Garden Dog.

Shack Shack Secret Menu Dessert Options

Root Beer Float

A root beer float will give anyone over the age of 50+ some retro vibes from the American Diners from the 50’s and 60s. What makes this one unique and richer and more intense is that it’s made with vanilla custard!

To order – order a bottle of root beer with a scoop of vanilla custard to be added right in.
