Unfortunately, you won't be able to find any burgers with buns that are gluten-free Sonic. They don't claim that any of their buns are gluten free, but they do provide a list of the allergens present in their menu items to help you make an informed decision.

However, they do have a decent list of desserts that are marked gluten-friendly that you may want to check out.

In this guide, I'll share the items that Sonic has on their menu that do not contain gluten. However, it's important to note that these items may still come in contact with gluten since most of Sonic's menu items contain wheat.

History of Sonic

Founded in the heartland of America, Sonic Drive-In, commonly known as Sonic, has a rich history that dates back to 1953. Troy Smith established the first-ever Sonic restaurant in Shawnee, Oklahoma.

Initially, the restaurant was named "Top Hat," but it was later renamed "SONIC" in 1959, an acronym for "Service at the Speed of Sound." The name was a perfect fit, reflecting the restaurant's quick service and drive-in concept, a novelty at the time.

Over the years, Sonic has evolved significantly, expanding its drive-in concept across the United States. Today, Sonic boasts over 3,500 locations across 45 states, making it one of the country's largest chain of drive-in restaurants.

Despite the changes and expansion, Sonic has remained true to its roots, offering a unique dining concept that allows customers to enjoy their meals in the comfort of their cars.

While Sonic is renowned for its wide range of fast-food offerings, including burgers, hot dogs, and milkshakes, it has also made efforts to cater to the dietary needs and preferences of its customers.

But do they have gluten free items? Let's find out.

Is There Gluten Free Food at Sonic?

Yes, Sonic does offer a selection of gluten-free items on their menu. However, it's important to note that Sonic is not a dedicated gluten-free facility and there may be a risk of cross-contamination.

For those with celiac disease or a severe gluten intolerance, it's always best to speak with the restaurant directly to understand their preparation methods and any potential risks.

Their gluten-free offerings primarily include drinks, slushes, and certain toppings and condiments. Sonic's real ice cream and many of their shakes are also gluten-free, though it's always wise to double-check for any added toppings or mix-ins that could contain gluten.

Their grilled foods, including burgers and hot dogs, could be gluten-free if ordered without the bun.

However, be aware that these items are cooked on the same grills as gluten-containing items, which could lead to cross-contamination.

While Sonic does provide options for those following a gluten-free diet, it's important to be vigilant and ask questions about their food preparation to ensure your meal is safe to consume.

It's worth noting that Sonic states on its official allergen menu that they cannot eliminate the risk of cross-contact or guarantee that any item is free of any allergen and no items are certified gluten-free.

Frequently Asked Questions

Does Sonic have a dedicated gluten-free menu?

While Sonic does not have a separate gluten-free menu, they do offer several items that are naturally gluten-free or can be modified to be gluten-free. This includes some of their drinks, sides, and dessert items. However, it's important to note that cross-contamination may occur, as these items are prepared in the same kitchen as gluten-containing foods.

Are Sonic's fries gluten-free?

While Sonic's fries are made from potatoes and fried in vegetable oil, they are not considered gluten-free due to the potential for cross-contamination with other items that contain gluten in the fryer.

Can I get a gluten-free burger at Sonic?

At this time, Sonic does not offer gluten-free buns or bread, so their burgers cannot be made completely gluten-free. However, you can order a burger without the bun for a low-carb, gluten-free option.

How can I ensure my food is gluten-free at Sonic?

The best way to ensure your food is gluten-free at Sonic is to communicate your dietary needs to the staff. They can guide you to the best options and take steps to avoid cross-contamination. However, as mentioned earlier, there is always a risk of cross-contamination in a kitchen that also prepares gluten-containing foods.
