I’ve never bothered with a post for Chick-fil-A. They fry their food in peanut oil, and our kids are anaphylactic to peanuts, so it seemed kind of pointless. Tragically, it appears that they also hold the same opinion about peanut oil that many restaurants hold about soybean oil, namely that the presence of soybean oil doesn’t indicate that there is soy in the food.
Chick-fil-A uses 100% refined peanut oil for all of our breaded chicken. According to the FDA, highly refined oils such as soybean and peanut oil are not considered allergenic, and therefore are not labeled as such.
Regardless of whether there’s peanuts in the food, Chik-fil-A’s menu is full of soy. The few items that are listed as not containing soy are items that are likely to have soybean oil, and since they don’t list any item fried in peanut oil as containing peanuts, I’m going to guess that they contain soybean oil. So tragically, I’d say that makes Chik-fil-A a big old double “No”. Source: http://media.chick-fil-a.com/Media/PDF/Allergen_April2014.pdf
