The Standard ShackBurger: A Gluten-Filled Start
The classic Shake Shack ShackBurger is not gluten-free. The bun contains wheat. For anyone with a gluten intolerance or Celiac disease, consuming the ShackBurger as-is would not be safe. The base ingredients—the 100% all-natural Angus beef patty, American cheese, and ShackSauce—do not inherently contain gluten, but they are all assembled in a kitchen environment with active gluten-containing ingredients.
How to Order a Gluten-Free ShackBurger
Shake Shack offers options for customers who need to avoid gluten. You can enjoy a version of the classic burger while minimizing your risk.
The Gluten-Free Bun Option
Most U.S. Shake Shack locations offer a certified gluten-free bun. This is an effective modification for those on a gluten-free diet. The nutritional information for the gluten-free bun is typically available on the Shake Shack website.
The Lettuce Wrap Alternative
A lettuce wrap is an alternative if you prefer a bun-free option or are dining at a location without gluten-free buns. You can request any burger to be served on a crisp lettuce wrap instead of a bun.
Communicating Your Needs
Communicate your dietary needs clearly to the staff. You should explicitly state that your order is for a gluten allergy to ensure extra precautions are taken. This may include employees changing gloves and preparing the burger on a clean surface.
Understanding Cross-Contamination Risks at Shake Shack
Shake Shack's kitchens are not certified gluten-free, which means there is a significant risk of cross-contamination. For individuals with Celiac disease, this risk should be taken seriously.
Shared Fryers
Shake Shack’s crinkle-cut fries are fried in oil that is shared with gluten-containing items, such as the 'Shroom Burger and the Chicken Shack. While the fries themselves are not made with gluten-containing ingredients, they are not safe for Celiac patients due to the shared fryer.
Shared Prep Surfaces
Workers handling both regular and modified orders often use the same surfaces, utensils, and gloves. Your modified burger could come into contact with gluten unless flagged as an allergy.
Shared Frozen Custard Stations
The custard station is another area of concern. It often contains gluten-containing mix-ins, increasing the risk of cross-contamination.

Menu Items to Avoid for Gluten-Free Diets
Several other menu items are not gluten-free. These include:
- 'Shroom Burger: The mushroom patty contains gluten.
- ShackStack: Includes the gluten-containing 'Shroom Burger patty.
- Chicken Shack & Chicken Bites: Both are hand-breaded with a wheat-containing coating.
- Fried Items (like fries): They are prepared in a shared fryer, making them unsafe due to cross-contamination.
- Concretes: These are blended desserts with mix-ins that often contain gluten.
Conclusion: Can You Eat Gluten-Free at Shake Shack?
Yes, you can get a gluten-free burger at Shake Shack by opting for a gluten-free bun or a lettuce wrap. The core ingredients of the ShackBurger—the beef patty, cheese, and vegetables—are inherently gluten-free. Shake Shack's kitchens are not set up to prevent cross-contamination completely. For individuals with Celiac disease, this presents a real risk. It is essential to communicate your allergy to the staff and understand that a completely safe, risk-free meal may not be possible. Consult the official Shake Shack Allergen Information page for the most up-to-date allergen information.
