Is anything at Shake Shack gluten-free?

4 min read

According to Shake Shack's official allergen guide, some menu items can be prepared gluten-free upon request at most locations. For diners with celiac disease or gluten sensitivity, navigating the menu requires attention to preparation methods and significant potential cross-contamination risks to determine if anything at Shake Shack is truly gluten-free.

Quick Summary

Shake Shack offers modified menu items like burgers on a gluten-free bun or lettuce wrap, and the base of their frozen custard is inherently gluten-free. Shared fryers and prep surfaces create a significant cross-contamination risk, which is critical for those with celiac disease.

Key Points

  • Modified Burgers are Possible: Order any burger with a gluten-free bun (available at most U.S. locations) or a lettuce wrap.

  • Fries Are High-Risk: Despite being inherently gluten-free, Shake Shack's fries are cooked in shared fryers, making them unsafe for those with celiac disease.

  • Frozen Custard Requires Caution: The base custard is gluten-free, but mix-ins like malt and cookies, along with shared equipment, pose a cross-contamination threat.

  • Communicate Your Allergy: Always inform the staff about your gluten allergy to ensure proper precautions, such as using fresh gloves and clean preparation surfaces.

  • Avoid All Breaded Items: The 'Shroom Burger, Chicken Shack, Chicken Bites, and Concretes that contain mix-ins like cake or cookies are not gluten-free and must be avoided.

  • Check Local Availability: Not all locations may offer gluten-free buns, so it's wise to call ahead to confirm availability before visiting.

  • Simple is Safest: For those with high sensitivity, the safest order is a simple beef patty with a lettuce wrap and basic, low-risk toppings, avoiding all fried items and complex desserts.

Navigating the Shake Shack Menu for Gluten-Free Options

For those managing a gluten-free diet, Shake Shack offers several potential options, but careful ordering and awareness of potential cross-contamination are essential. While Shake Shack provides an allergen guide, personal communication with staff is always the safest route for those with celiac disease or high sensitivity. The availability of gluten-free buns at most locations offers a promising starting point for a classic burger experience without the wheat-based potato roll. However, it's the finer details of preparation that determine true safety.

How to Order a Gluten-Free Burger or Hot Dog

To enjoy a burger or hot dog, the primary modification is replacing the standard bun. This can be done in two ways at most U.S. Shake Shacks:

  • Request a gluten-free bun: Most locations offer a dedicated, sealed gluten-free bun for an extra charge.
  • Opt for a lettuce wrap: A healthier and often safer option is to have your burger or hot dog served in a crisp lettuce wrap instead of a bun.

When placing an order, especially for those with celiac disease, it is crucial to explicitly state that it is for a gluten allergy. This protocol should trigger specific safety measures, such as the use of a clean tray, fresh gloves, and separate preparation to minimize cross-contamination from surfaces, utensils, and other ingredients. The core beef patties and all-beef hot dogs are naturally gluten-free. However, toppings and sauces like the ShackSauce could have a potential risk of cross-contact with wheat during factory processing. A plain cheeseburger or hamburger with basic toppings like lettuce and tomato is a safer alternative if this is a concern.

The Controversial Case of Shake Shack's Fries

Shake Shack's crinkle-cut fries are a fan favorite, and their official allergen information confirms they do not contain gluten as an ingredient. The critical issue, however, lies in their preparation. The oil in the fryers is filtered through the same equipment used for gluten-containing items, such as the fried 'Shroom Burgers and chicken products. For individuals with celiac disease, this practice makes the fries an unsafe choice due to the high risk of cross-contamination. Anecdotal evidence, including former employee reports and recent testing, reinforces the need for caution, as gluten-containing items are handled at the same fry stations. The safest approach for a strict gluten-free diet is to skip the fries altogether.

Frozen Custard, Shakes, and Mix-Ins

The base of Shake Shack's frozen custard and milkshakes is naturally gluten-free. This is great news for dessert lovers, but again, caution is necessary, particularly with shakes and concretes. The dessert station uses shared blenders, scoops, and other equipment for items containing gluten, such as malt powder, Oreo cookies, and concrete mix-ins like graham cracker crust or cake.

To order safely:

  • Stick to simple, core flavors without any mix-ins.
  • Order the frozen custard in a cup, not a cone.
  • Inform the staff of your allergy and ask them to use a freshly cleaned blender for shakes or fresh scoops for custard to minimize cross-contamination.

What to Avoid: The Off-Limits List

To ensure a safe dining experience, several menu items should be strictly avoided by anyone on a gluten-free diet, regardless of sensitivity level. These items are inherently made with gluten and cannot be modified to be safe:

  • The 'Shroom Burger and ShackStack (which includes the 'Shroom Burger patty)
  • The Chicken Shack and Chicken Bites
  • Concretes that contain gluten-based mix-ins
  • The standard Grilled Cheese sandwich
  • Beer
  • The standard potato roll bun that comes on all regular burgers and hot dogs

Comparison of Gluten-Free Friendly Options

Menu Item Inherent Gluten-Free? Cross-Contamination Risk Modification Required Verdict for Strict GF Diet
Beef Burger Patty Yes Low (with protocol) GF bun or lettuce wrap High (safest burger option)
Hot Dog Yes Low (with protocol) Lettuce wrap (no GF hot dog bun) High (safe with lettuce wrap)
Fries Yes High (shared fryer) None Low (Avoid)
Frozen Custard (Base) Yes Low (with protocol) Cup instead of cone High (safe with precautions)
Shakes (Core Flavor) Yes Medium (shared blender) Specify allergy Medium (Cautious ordering)
Breaded Chicken No N/A N/A Low (Avoid entirely)
'Shroom Burger No N/A N/A Low (Avoid entirely)

Conclusion

While Shake Shack has made strides by offering gluten-free buns and providing an allergen guide, the complete responsibility for a safe gluten-free meal still rests heavily on the customer. Key challenges, particularly the shared fryers for french fries and the risk of cross-contamination at the shake station, mean that a completely risk-free experience is not guaranteed, especially for those with celiac disease. The best practice is to order a modified burger or hot dog with a lettuce wrap and communicate your allergy clearly to the staff. It's best to forgo the fries and be extremely selective with frozen custard and shakes. By following these guidelines and referencing the official Shake Shack Allergen Information page, you can make an informed choice and enjoy a meal with greater confidence.
