The Official Stance: Cross-Contamination is Key
McDonald's in many countries, including the United States, does not certify any menu items as gluten-free. This is primarily due to the significant risk of cross-contamination in their kitchens, where shared equipment and preparation areas are used for both gluten-containing and non-gluten-containing items. Individuals with celiac disease or severe gluten sensitivity should be aware of this risk.
Significant Regional Differences
McDonald's menus and ingredient sourcing vary globally, significantly impacting gluten-free options.
- United States: McDonald's fries in the U.S. are not considered gluten-free due to a natural beef flavoring containing wheat derivatives. Shared fryers also pose a cross-contamination risk.
- United Kingdom & Australia: Fries in the UK and Australia are gluten-free by ingredient but are still subject to cross-contamination in shared fryers. Checking with local staff is recommended.
- Europe: Some European countries, such as Spain, Portugal, and Norway, offer certified gluten-free buns and items prepared separately to minimize cross-contamination.
What to Order: A Breakdown by Item
For those comfortable with the risk of cross-contamination, some items are gluten-free by ingredient.
Naturally Gluten-Free (by ingredient)
- Beverages: Most sodas, milkshakes, and McCafé coffee drinks are generally gluten-free by ingredient. Consult regional allergen guides for specifics.
- Packaged Sides: Apple slices are a safe option as they are prepared off-site.
- Desserts: Plain sundaes (without a cone) and some specific McFlurry flavors may be gluten-free by ingredient, but assembly involves cross-contamination risk.
Modified Items (with cross-contamination risk)
- Bunless Burgers: Ordering a burger without the bun is an option, as the meat patties are typically gluten-free by ingredient. However, shared grills and prep areas pose a high risk of cross-contamination.
- Sauces: Many standard sauces in the US like ketchup, mustard, and mayo are gluten-free by ingredient.
What to Avoid: The No-Go List
Unless certified gluten-free options are available in your location, avoid the following:
- Chicken Products: All breaded chicken items, including McNuggets and sandwiches, contain wheat.
- All Breads: Buns, biscuits, and muffins contain wheat.
- Fried Items (US): Fries and hash browns in the US contain wheat.
- Desserts with Mix-ins: McFlurries with gluten-containing toppings are not safe.

Important Takeaways for Ordering
- Check Local Policies: Always consult the McDonald's website for the specific region.

- Use Caution with Modifications: Be aware of cross-contamination risks with modified orders like bunless burgers.
- Choose Safest Items: Packaged items like apple slices and simple drinks are the lowest risk.
Conclusion: A Risky Proposition for Many
While some items at McDonald's are free of gluten-containing ingredients, the high likelihood of cross-contamination makes dining there risky for individuals with celiac disease or severe gluten sensitivity. To minimize risk, check local allergen information online, ask staff specific questions, and understand the inherent limitations of a fast-food kitchen. For those with less severe sensitivity, simpler, non-fried items may be acceptable.
