What to know before you order.
If you're eating at McDonald's with an egg allergy, breakfast sandwiches aren't the only place you'll want to look. The Egg McMuffin names egg directly, and the Surf and Turf ingredient panel lists egg in tartar sauce. McDonald's also says normal kitchen operations may involve shared cooking and preparation areas, equipment, and utensils.
Breakfast deserves a close look because egg is central to many sandwiches, but sauces can matter outside the breakfast menu too. The Surf and Turf panel identifies egg in tartar sauce. You'll still need to ask the location about its current stations, utensils, and assembly process because the published pages don't describe egg-specific controls.
A practical way to sort your options.
These labels can help you narrow the menu. “Worth asking about” is a place to continue the conversation, not a promise.
Clear conflicts
- Egg McMuffin and other items built around a cooked egg
- Surf and Turf as listed, because its tartar sauce contains egg
Options you may want to ask about
- A simple item whose current component panels do not list egg, after checking every sauce and topping
- A beverage with a complete current ingredient listing, after confirming the dispensing setup
What still needs checking
- A sandwich ordered without an egg or egg-containing sauce unless staff can explain how the modified order is assembled
- Limited-time and local items without a current item-level panel
Questions you can ask restaurant staff.
- Does every component of this order, including the sauce, list egg today?
- How will a no-egg modification be assembled, and can clean utensils and a clean surface be used?
- Is this item handled near breakfast eggs or tartar sauce during the current shift?
