Carhops on roller skates. SuperSonic Bacon Double Cheeseburger. Chili cheese tots. Is your mouth watering? I hate to be the bearer of bad news, but Sonic is NOT the place to go if you’re gluten-free. Unless you’d like a Dr. Pepper, bottle of water, or a sugar packet.

In all seriousness, the Sonic menu is filled with GLUTEN. Sonic’s allergen disclaimer essentially covers 99.9% of the menu:
Warning: fried foods may be exposed to gluten and allergens. Fryer oil may come in contact with items containing milk, egg, fish, shellfish, soy, wheat and gluten because fried items are not always fried in designated stations.

Blended/mixed drinks and frozen desserts may come in contact with milk, egg, soy, wheat, gluten, peanuts and tree nuts.

So, what can you order that’s gluten-free at Sonic? Based on their allergen menu, you can safely order their fountain drinks, coffee and water. Sadly the rest of the menu either contains gluten or is cross contaminated due to shared fryers and prep stations. I have reached out to Sonic to clarify if their Frito chips and apple slices are in individual packets (snack packets) or are they “loose”. I’ve also asked which condiments are in individual packets (not cups). If you enjoy eating ketchup packets, then Sonic is the place for you! Sidenote: if you like eating ketchup packets, that’s kind of weird and you might want to talk to someone (even though most ketchup is gluten-free). I’ll update this post as soon as I hear back from Sonic’s customer service.


Sonic‘s allergen menu is extremely transparent in breaking down their allergen information. With that said, the allergen menu on Sonic’s website is dated May 2, 2016:

M = Milk, E = Eggs, S = Soy, T = Tree Nuts, P = Peanuts, F = Fish, SH = Shellfish, W = Wheat, G = Gluten
[ ] = May Contain
NONE = None Present

Please remember that restaurants can change their menus and food preparation at any time. Always ask before you order and if your server doesn’t understand your need to be gluten-free, go elsewhere.
