Shake Shack is a popular fast-casual restaurant chain known for its delicious burgers, crinkle-cut fries, and shakes. But if you’re following a gluten-free diet due to celiac disease, gluten sensitivity, or personal preference, you might wonder: Are Shake Shack fries gluten-free?
Are Shake Shack Fries Gluten-Free?
Yes, Shake Shack’s standard crinkle-cut fries are gluten-free. They are made from potatoes, sunflower oil, and salt, with no gluten-containing ingredients. Additionally, they are cooked in a dedicated fryer, reducing the risk of cross-contamination with gluten items like chicken or breaded foods.
However, Shake Shack states that their kitchens are not 100% gluten-free environments, meaning there’s still a slight chance of cross-contact. If you have celiac disease or severe gluten intolerance, you should exercise caution.

Cross-Contamination Risks at Shake Shack
While Shake Shack’s fries are made without gluten ingredients, cross-contamination can occur in the kitchen. Here’s why:
- Shared cooking spaces – Though fries have a dedicated fryer, other gluten-containing foods (like chicken tenders or buns) are prepared nearby.
- Handling procedures – Employees may handle gluten-containing items before touching fries.
Should You Eat Shake Shack Fries If You Have Celiac Disease?
- Low to moderate risk – The dedicated fryer minimizes risk, but it’s not 100% safe for those with severe gluten allergies.
- Ask staff – Request that they change gloves and avoid shared utensils when preparing your order.
