In this guide, you’ll discover 17 of the most popular and mouthwatering options in 2025, along with tips on how to order them.

1. Peanut Butter & Bacon ShackBurger

One of the boldest creations on the Shake Shack Secret Menu is the Peanut Butter & Bacon ShackBurger.

It’s a great pick for those looking to step outside of traditional burger toppings. Pair it with fries for a truly indulgent meal.

2. Quad Burger (The “Meat Lover’s Dream”)

For fans who believe that more is always better, the Quad Burger takes the ShackBurger to the next level.

3. Cheese Fries with Extra Cheese on the Side

Regular cheese fries are a popular order, but the secret upgrade is to ask for extra cheese sauce on the side. This allows you to dip fries or even add more creamy goodness to your burger. The Shack’s cheese sauce has a unique taste—rich, savory, and smooth—which makes this simple hack one of the easiest ways to level up your meal.

4. ShackBurger with “Well-Done” Fries

While fries come in many styles, ordering them “well-done” gives you an extra crispy texture. This trick is a fan favorite and not commonly known by casual diners. Pairing crispy fries with the ShackBurger adds the perfect crunch to balance the juicy burger. If you love golden fries that stay crisp longer, this is a must-try option.

Not in the mood for a burger? The secret Grilled Cheese Sandwich is a surprising option. It’s made by flipping the burger bun inside-out, grilling it, and adding melted American cheese. Kids and adults alike enjoy this classic comfort food. You can even add a beef patty or bacon if you want a heartier version of the dish.

6. Shandy (Lemonade + Beer)

For adults looking for something refreshing, the secret Shandy combines Shack-made lemonade with draft beer. It creates a light, crisp, and slightly sweet beverage perfect for warm weather.

8. Shack-Cago Dog with Extra Veggies

The Shack-Cago Dog is already loaded with toppings like relish, onion, cucumber, and sport peppers, but insiders know you can ask for extra veggies. This secret tweak gives you a hot dog that feels more like a meal than a snack. It’s a fresh, crunchy, and flavorful way to enjoy one of the Shack’s signature non-burger items.

9. Protein Style Burger (Lettuce-Wrapped)

For health-conscious eaters, the Protein Style Burger swaps out the bun for crisp lettuce leaves. This low-carb option still packs all the flavor of the ShackBurger while keeping things lighter. It’s one of the most popular Shake Shack Secret Menu hacks because it caters to those on keto or gluten-free diets without sacrificing taste.

15. Shack Sauce Fries

Instead of sticking with plain ketchup, try ordering fries topped with ShackSauce. This secret hack upgrades a simple side into something addictive. The tangy, creamy sauce coats each fry perfectly, giving you a new way to enjoy a fan-favorite side dish. Many fans agree that this is one of the best fries hacks on the list.

16. Black & White Shake with Custom Additions
