  • Onions
  • Batter mix (enriched wheat flour, salt, whey, dextrose, leavening, and partially hydrogenated soybean oil)
  • Vegetable oil (soybean and/or canola oil)

It’s crucial to remember that the batter mix contains whey, a milk byproduct. This means that vegans and those who are lactose intolerant should avoid eating Burger King onion rings.
