As of September 2011, Wendy’s is using buttered buns on many of their burgers and sandwiches. Be sure to ask before you order to ensure that whatever you are ordering has not been buttered or that it won’t be toasted (as the buttered buns are toasted). Here is information about that change to clarify, courtesy of Allergy Eats:

The buttered buns will be used on their seven premium burgers – Dave’s Hot ‘N Juicy 1/4 lb, 1/2 lb, & 3/4 lb, the Bacon Deluxe single & double, and the Baconator single & double.”

“The buttered buns will NOT be used on the value burgers – Jr. Bacon Cheeseburger, Cheeseburger Deluxe, Double Cheeseburger Deluxe, Double Stack.  In addition, all of the kids burgers will be free of the buttered buns.”

“All of the buttered buns will be toasted, as we believe all of the adult burger buns are.  Therefore, only the children’s burgers will have buns that are free of cross-contamination risk from the toaster. Adult burgers with non-buttered buns will still be risky for those with a dairy allergy, so the best bet is to request a non-toasted bun.”

  1. Wendy’s allergy menu says the breaded crispy chicken, spicy chicken, and ultimate grilled have milk in them.

  2. What about the kids crispy chicken sand which or their nugget products? Couldn’t find any product info, could it have been in the batter?

    • Hi, Melissa,

      As noted above, Wendy’s fries are cooked in the same oil as ingredients that contain dairy, but the fries themselves are dairy free according to their website.

  3. I just wanted to clarify the opening statement regarding Wendy’s using the same spoon to spread ketchup and mayo. Wendy’s does not use utensil for spreading of condiments. All condiments are kept in squeezable bottles. All condiments are squeezed in the form of a “W” on the bun. Each ingredient container does not come in contact with any other. Other than that, great job.
