Summary of Gluten Free Menu Options at Sonic

Pro tips, fun ideas/food hacks, and a quick summary of everything gluten free at Sonic

  1. When you order at the drive-through, in-store, or even online, tell them you have an allergy or Celiac Disease so they take precautions with your food, slushes, and sides.
  2. You can try adding things like the cheese sauce, grill items, and other toppings/condiments to your fries.
  3. Sonic has just 9 ratings on Find Me Gluten Free with an average of 2.5 stars indicating a very poor experience for most gluten free customers. Low reviews and low stars means there aren’t many options and most people with Celiac/gluten allergies avoid Sonic.
