Shake Shack Allergen Menu – Comprehensive guide
If you love Shake Shack’s burgers, fries, or shakes but worry about food allergies, you’re not alone. Maybe peanuts make your throat itch, or dairy sends your stomach into a spin.
Good news: Shake Shack’s got your back with their allergen menu. It’s like a cheat sheet that tells you what’s safe to eat and what to skip. This article breaks down everything you need to know about the Shake Shack allergen menu what it covers, how to use it, and some smart tips to enjoy your meal without a worry. Let’s dig in and figure out how to keep your taste buds happy and your allergies quiet!
What’s the Shake Shack Allergen Menu?
The Shake Shack menu is a handy guide that lists what’s in their food and flags stuff that might cause trouble like nuts, dairy, or gluten. Shake Shack knows not everyone can eat everything, so they put this together to help you pick what works for you.
You won’t find it hanging on the wall at the restaurant, but it lives online at shakeshack.com under the “Allergy” section. It covers all the big menu items: burgers, chicken, fries, shakes, and spells out which ones have the top allergens that bug most people.

This isn’t just a random list. Shake Shack works hard to keep it real, using info from their suppliers and testing labs. They update it when ingredients change, so you’re not stuck guessing. Whether you’re grabbing a ShackBurger or eyeing those crinkle fries, this menu helps you dodge the danger zones.
The Big Allergens They Track
Shake Shack zeros in on the eight major allergens the FDA says matter most. These are the troublemakers that mess with a lot of folks:
- Milk: Think cheese, shakes, or sauces.
- Eggs: Shows up in mayo or custard.
- Peanuts: Not huge on the menu, but watch out.
- Tree Nuts: Like almonds or walnuts mostly in desserts.
- Soy: Hides in sauces and frying oil.
- Wheat: Buns and breadings bring the gluten.
- Fish: Rare, but some specials might have it.
- Shellfish: Not a regular player, but check specials.
They also warn about sesame, which popped up on buns in some spots by 2025. If any of these bug you, the allergen menu marks them with an “X” next to the food so you know what’s off-limits.
Breaking Down the Menu
Let’s walk through some Shake Shack classics and see what the allergen menu says. This way, you get a feel for what’s safe or tricky.
Burgers
- ShackBurger: Beef’s fine, but the bun’s got wheat and sesame, the cheese has milk, and ShackSauce packs eggs and soy. Allergic to those? Skip it or ditch the bun and sauce.
- ‘Shroom Burger: A veggie option with a fried mushroom. It’s got wheat and milk from the bread and cheese, plus egg in the sauce. Cross-contact with fry oil’s a risk too.
Chicken
- Chicken Shack: Crispy chicken’s cool, but the bun has wheat and sesame, and the buttermilk mayo brings milk and eggs. Soy’s in the frying oil too. Swap the bun for lettuce if gluten’s your enemy.
Fries
- Crinkle-Cut Fries: Good news—these are usually safe from the big eight. They fry them in soybean oil, so soy’s there, but no gluten, nuts, or dairy unless you add cheese sauce (milk alert!).
- Cheese Fries: That sauce adds milk, so steer clear if dairy’s a no-go.
Shakes and Custard
- Vanilla Shake: Milk and eggs are the stars here custard’s the base. No dodging that.
- Concretes: These mix-ins (like cookies or candy) might sneak in nuts or wheat. The menu says avoid them if allergies are serious.
Breakfast (Select Locations)
Bacon, Egg N’ Cheese: Eggs and milk in the mix, plus wheat in the bun. Soy’s in the oil too. Tough one to tweak.

How to Use the Allergen Menu
Figuring out this menu’s a breeze if you follow these steps:
- Hit the Website: Go to shakeshack.com, click “Menu,” then “Allergy.” You’ll see a chart.
- Pick Your Allergens: Check boxes for what you can’t have, like milk or nuts. Foods with those get an “X.”
- Scan Your Faves: Look at what you want to order. An “X” means trouble; no “X” means it’s probably okay.
- Talk to the Crew: Tell the staff your allergies when you order. They can double-check or tweak stuff, like no cheese or a lettuce wrap.
The online chart’s your first stop, but it’s smart to chat with the team at your Shack. Some locations tweak recipes or share fryers, so you want the latest scoop.
Watch Out for Cross-Contact
Here’s a heads-up: Shake Shack kitchens aren’t allergy-free zones. They fry chicken and fries in the same oil at most spots, so even “safe” stuff might pick up traces of allergens, like soy or milk from cheese fries. The allergen menu warns about this, especially for concretes with mix-ins. If you’re super sensitive (like if peanuts could send you to the hospital), ask the staff how they handle things. They might clean gear or grab fresh ingredients if you explain.
Tips to Eat Smart at Shake Shack
Want to enjoy your meal and stay safe? Try these moves:
- Ditch the Bun: Gluten or sesame got you down? Get a lettuce wrap for burgers or hot dogs. It’s free and easy.
- Skip the Sauce: ShackSauce and mayo have eggs and soy. Go plain or ask for ketchup instead.
- Check the Fries: Ask if they use a separate fryer. Most don’t, but it’s worth a shot.
- Avoid Custard: Milk and eggs rule here—no workaround unless they bring back a dairy-free option.
- Order Online: The app lets you flag allergies and customize, so the kitchen knows before you roll up.
Why Shake Shack Cares
Shake Shack doesn’t mess around with this stuff. They started as a tiny cart in 2001 and blew up because people love the vibe and the food. Keeping customers safe keeps them coming back. They’re not perfect, cross-contamination’s a real thing but they give you the tools to make smart picks. Plus, they use cage-free eggs and antibiotic-free meat, so you know they’re serious about quality.
What’s Missing?
The allergen menu’s solid, but it’s not flawless. It skips some local specials or seasonal items like a pesto parm fry deal in the UK. Mix-ins for concretes are a gray area too; they just say “avoid” instead of listing every candy or cookie. If you’re at an airport Shack or a new spot, call ahead or check social media for updates. Things change fast in 2025!
Conclusion
Totally! The Shake Shack allergen menu makes it doable if you’ve got allergies. You might not chow down on a shake or a loaded burger, but fries, a plain patty, or a lettuce-wrapped Chicken Shack can work. Just use the online guide, talk to the crew, and know your limits. It’s all about enjoying that Shack flavor without the stress.
