With lines out the door for over a decade now, Shake Shack never ceases to draw in loyal customers with their delicious gourmet fast food. Famous for their massive menu of frozen custards, shakes, and juicy burgers, Shake Shack combines modern tastes with retro flair.
There are endless cult classics at Shake Shack that won’t ever go out of style, but there’s more to the menu than meets the eye.
Just when you thought Shake Shack’s regular menu couldn’t be beaten, they introduced an incredible secret menu. From little hacks to the regular menu to unique and new creations, this list has it all.
Shake Shack Secret Menu
I’ve outlined some of my favorite menu items from Shake Shack’s secret menu. From the Quad Burger to the iconic Shandy, there’s something for every Shack fan on this list.
The best part? They’re adding new items to the menu all the time.
Protein Style Burger
Anyone on a low-carb diet or who is gluten-free can enjoy a delicious Shake Shack burger!
Taking a leaf out of In-N-Out’s secret menu, you can now order any burger on the menu “protein style”, and they will take off the bun.
The same juicy patty and fresh toppings will instead be served on a bed of crispy lettuce.
You might think you’d miss the signature potato bun to try this out.
But, If you want to enjoy the indulgence of Shake Shack without as much guilt, ask for a burger protein style, or just request it “bunless.”
Nothing beats the nostalgic first bite of ooey-gooey grilled cheese. At Shake Shack, they take this classic to another level by making it on their pillowy potato buns.
Ask for a grilled cheese at the counter, and they’ll serve you a bun toasted on both sides with pure butter, and layers of ultra-melty American cheese.
This is the perfect secret item if you’re recovering from a wild night out, or if you just want to feel like a kid again.
Add some crispy bacon to it and you’ll have the ultimate breakfast sandwich.
Shake Shack Quad Burger
Channel your competitive side and see if you can handle the meat on this four-layered delicious monstrosity.
This is more of a hack than a specific secret menu item, as you can get any burger on Shake Shack’s menu made quad-style – just order your favorite and ask for four meat patties.
Each one will be smothered with cheese and piled high to perfection.
This might seem like a daunting challenge to some, but when you’re truly hungry, nothing satisfies like a quad burger.
This is also the ideal burger for anyone looking to up their protein game after a workout. If you can conquer the quad, you’ll guarantee gains!
The Shack-Cago hotdog is one of Shake Shack’s most popular menu items, and now you can get it in burger form at some locations! It’s a classic patty with all the toppings of a Shack-Cago dog, including
- Special relish
- Celery salt
Some locations will make you this delicious combination if you just ask, but others are less inclined.
However, it’s so good that if needed, you can make it yourself. Just order a Shack-Cago dog and transfer the toppings to a plain burger and you’re good to go.
It might sound like a lot of effort, but trust me, it’s worth it.
Shack Sauce and Cheese Fries
Is there anything better than a gooey basket of cheese fries? Yes – cheese fries with Shake Shack’s iconic and delicious Shack Sauce.
It’s a mayo-based creamy sauce with ketchup, mustard, and a secret blend of spices that give it a sweet, sour, and spicy combination.
The combination of melted cheese and shack sauce will give you every flavor and texture you need in one bite.
Just ask for cheese fries with a side of Shack Sauce and the staff will know just what to do. If you’re looking for a little more spice, get it topped with chilies too.
Root Beer Float
What’s more American than a root beer float? Not much! Shake Shack’s secret version is even better than the classic because of their smooth and extra creamy vanilla custard.
Just order a bottle of root beer and ask for a scoop of that delicious custard to be added in.
The combination of fizzy and refreshing root beer with the decadent custard is the perfect dessert or a drink on a hot summer’s day.
Try it with the grilled cheese and you’ll feel like you’re in a retro diner in the middle of Shake Shack.
The Shake Shack Shandy is worth a try. It’s a mix of half beer, half lemonade. If that doesn’t sound immediately appealing, I get it.
But, trust me when I say you’ll be a convert after one sip. Think of it like an Arnold Palmer that’ll give you a buzz, and your life will change.
This is the perfect drink to accompany a big burger on a hot day, and you’ll be so refreshed sitting outside with this crisp and slightly sweet drink.
Ask for a Shandy at the counter and most staff will know what you want. If they don’t, just ask for some beer in your lemonade.
Ice Cream Sandwich
Shake Shack’s ice cream sandwich gained fame on Instagram, where thousands of people shared their pictures of this secret stack of deliciousness.
It’s not a typical ice cream sandwich by any means, but once you try it, you’ll keep coming back for more.
Order a regular scoop of the ice cream of your choice and a potato bun on the side.
Then, put the ice cream between them to make your own sweet and slightly salty ice cream bun.
The best part is that the potato bun goes with any flavor. My favorites are the Caramel Popcorn and Mud Pie.
Peanut Butter and Bacon ShackBurger
Okay, hear me out on this one. This unique burger was on the actual Shake Shack menu for one week and sold out in minutes each day, so I’m not the only one addicted.
This is a must-try for anyone who likes a sweet and salty combination.
The creamy, sweet peanut butter mixed with the rich, tangy bacon is unbeatable. Order a Bacon ShackBurger with a side of peanut sauce.
Then, drizzle the sauce over the burger and you’ll never go back. I know peanut butter and beef might not be a natural choice, but I promise you’ll be pleasantly surprised.
