Sonic Dairy-Free Menu Guide with Allergen Notes & Vegan Options

Last Update in September 2021! Here it is! Our long-awaited dairy-free menu guide for Sonic. This nostalgic fast food chain offers the classic drive-in experience, complete with carhops on roller skates. And we were pleasantly surprised by all of the options they offer without dairy! This guide includes menu items, custom order options, top allergen notes, and even a separate vegan menu.

Sonic Dairy-Free Menu Guide with Allergen Notes & Vegan Options

As with all of our guides, make sure you read all of the information and reference any custom order notes in parentheses! For example, if it says (no cheese), you must order without cheese to make it dairy-free by ingredients. We do our best to cover all the bases and details to help make your life easier.

More Allergen Notes: At last check, all of the following non-dairy options at Sonic were also made without tree nuts and peanuts, but the Signature Sauce packets have a “may contain” warning for peanuts. All of the following are also made without eggs, except the egg-specific items, slaw, mayonnaise, tartar sauce, honey mustard, crave sauce, and signature sauce. Sonic isn’t a great spot for gluten-free needs. Their fries, tots, dairy-free grilled proteins, and all dairy-free sauces and condiments listed below are made without gluten. But most prepared menu items contain wheat, and they do use shared fryers and grill their breads on a shared grill. Most items at Sonic are listed as containing soy, since they use bun oil, margarine, and fryer shortening for cooking that all contain soy.
