Summary of Gluten Free Menu Options at White Castle

Pro tips and a quick summary of everything gluten free at White Castle

When you order at the restaurant or on the app for delivery/pickup, tell them you have an allergy or Celiac Disease so they take precautions with your food.
White Castle has very limited options including a few sides, sliders without the bun, and condiments.
We are unable to find White Castle on Find Me Gluten Free, indicating no reviews/experiences from gluten free customers. This is yet another sign that for people with Celiac Disease or gluten allergies, you should proceed with caution and/or avoid this chain.
Personal experiences here are unknown. I will update this post if White Castle ever adds more safe gluten free options for consumers.
