Are McDonald's Fries Gluten Free?

Gluten verdict for McDonald's Fries: Check the Label

Check the Label McDonald's Fries

McDonald's fries have no gluten ingredients, but McDonald's will not guarantee them gluten free.

AU FSANZ & Coeliac Australia US FDA

Rated against the stricter of the two standards. Compare AU and US rules

McDonald's Australia fries are made from potato, oil, salt and dextrose with no gluten ingredients, and most restaurants cook them in a dedicated fryer. McDonald's still will not call them gluten free because of possible cross-contact in the kitchen.

Coeliac Disease

Many coeliacs eat McDonald's fries safely, but they are not certified gluten free. If you react to traces, ask staff about the fryer or skip them.

Gluten Sensitivity (NCGS)

Same as coeliac guidance.

Why Do McDonald's Fries Sometimes Contain Gluten?

There are no gluten ingredients; the issue is the lack of a gluten free guarantee and possible cross-contact.

Australia vs United States

Australia (FSANZ)

FSANZ allows a gluten free claim only with no detectable gluten, which McDonald's does not claim. The fries have no gluten ingredients but are not certified.

United States (FDA)

US McDonald's fries contain a wheat-derived flavouring and are treated differently; check the US allergen guide.

What to Watch For

Cross-contact in a busy kitchen, and a few stores that may share fryers.

Gluten Free Alternatives

If you need a gluten free substitute, consider: Hot chips from a dedicated gluten free fryer, oven-baked chips at home.
