Navigating the Fast-Food Landscape for Gluten-Free Fries
For individuals following a gluten-free diet, especially those with celiac disease, the simple joy of fast-food fries can be fraught with risk. The primary concern isn't the potatoes themselves, but the shared fryers used to cook gluten-containing items like chicken nuggets, onion rings, or breaded fish. This shared oil is a major source of cross-contamination. Understanding which chains prioritize dedicated equipment is essential for a safe dining experience. Fortunately, several major players offer dependable options, while others should be avoided completely.
The Safest Bets for Gluten-Free Fries
Five Guys
Five Guys stands out as a reliable choice for gluten-free fries. They offer both their classic Five Guys Style and Cajun fries, which are made from fresh-cut potatoes cooked in dedicated fryers with 100% refined peanut oil. Because their menu is so focused on burgers, fries, and hot dogs, they don't fry any other items, completely eliminating the risk of gluten cross-contamination from fried foods. The only other major allergen is the peanuts themselves, which are available for snacking in-store. For the most cautious diners, informing the staff of a celiac allergy can prompt them to take extra precautions, such as changing gloves.
Chick-fil-A
Chick-fil-A's popular waffle fries are naturally gluten-free and are typically cooked in a dedicated fryer. They use canola oil for their fries, separate from the peanut oil used for their breaded chicken. This practice significantly reduces the risk of cross-contact. However, staff and protocols can vary by location, especially in smaller venues like airports or malls. It is always recommended to ask an employee to confirm that the waffle fries are cooked in a dedicated fryer. For additional safety, customers with celiac disease can specify their allergy to ensure staff take extra care, such as changing gloves when packaging the order.
In-N-Out Burger
Primarily a West Coast chain, In-N-Out offers fresh, hand-cut fries that are safe for those avoiding gluten. Like Five Guys, fries are the only fried item on their menu, meaning their fryers are dedicated. They use sunflower oil to prepare their fries, which are simply potatoes and salt. In-N-Out is known for its ingredient freshness and, like other celiac-safe options, has specific procedures for handling allergy requests, such as preparing bun-free (protein style) burgers.
Red Robin
Red Robin is a sit-down restaurant, but it is a noteworthy option for gluten-free fries. They can cook their steak fries in a dedicated fryer upon request. Given the shared kitchen environment, it is crucial to clearly state the allergy to the server to ensure the correct protocols are followed. Red Robin also offers gluten-free buns for burgers, making a full, safe meal possible.
Chains to Approach with Caution or Avoid
Wendy's
While Wendy's fries themselves do not contain wheat ingredients, they are cooked in a shared fryer with menu items that contain gluten, such as breaded chicken nuggets. This presents a high risk of cross-contamination for anyone with celiac disease. Wendy's official allergen statement acknowledges this risk, and their fries are not considered safe for those with severe gluten sensitivities.
Burger King
Burger King's fries are also considered unsafe for celiacs due to cross-contamination. In many regions, they use a shared oil filtration system, meaning that even if different vats are used for different products, the oil passes through the same filter, contaminating it with gluten particles from items like onion rings.
McDonald's (USA)
This is a particularly tricky case. In the U.S., McDonald's fries contain a 'natural beef flavoring' that includes hydrolyzed wheat. Though the amount may be small and testing has shown low gluten levels, the presence of wheat makes them an absolute no-go for anyone with celiac disease or severe gluten intolerance. This is a major point of confusion, as many international McDonald's locations (like in the UK) have fries with no wheat flavoring and sometimes use dedicated fryers, but even then, shared equipment is a risk. The safest course for celiacs is to avoid McDonald's fries in the U.S. entirely.

How to Ensure Your Order is Safe
For those with celiac disease, simple menu research isn't enough. Communication is key to minimizing risk. When ordering:
- State your allergy clearly and early: Inform the cashier that you have a severe gluten allergy or celiac disease. This flags the order and alerts the kitchen staff.
- Ask about procedures: Inquire specifically about dedicated fryers and glove changes. Ask, “Are your waffle fries cooked in a dedicated fryer?” or “Could you please ensure a glove change for my order?”.
- Watch the preparation (if possible): If the counter is open, observe the process. For drive-thrus, this is not an option, but in-person dining allows for a visual check.
- Opt for sealed items: When available, choose pre-packaged, certified gluten-free options to completely eliminate cross-contact risk.
- Consider your sensitivity level: If you are extremely sensitive, eating out at any non-dedicated facility carries a small risk. For many, following the above steps at known celiac-friendly spots is sufficient, but some choose to avoid it altogether.
Conclusion: Making Informed Fast-Food Choices
Finding safe, gluten-free fries in the fast-food world is challenging but achievable with the right knowledge. Reliable choices like Five Guys, Chick-fil-A (with verification), and In-N-Out use dedicated fryers and have strong allergen protocols, offering a safe, tasty option. In contrast, chains like Wendy's and Burger King, and McDonald's in the U.S., pose significant risks due to shared fryers or gluten ingredients. By staying informed about each restaurant's specific practices and communicating clearly with staff, those on a gluten-free diet can confidently navigate their fast-food cravings, prioritizing both safety and flavor.
