Introduction
Sonic Drive-In is one of the largest and quite famous fast-food chains in the United States, serving burgers, breakfast, slushes, and the good old drive-in service-on-wheels. Offering an exciting outdoor seating arrangement, kid-friendly play areas, and delightful happy hour deals, the Drive-In is also very lively on the fun side and seems to appeal to a wider range of audiences, from toddlers to middle-aged people.
However, what about people who are allergic to certain foods?
The 2024 Allergen Menu would help a customer who is concerned about allergies quickly identify potential allergens in a favorite menu item as part of Sonic’s efforts to offer a safer, more enjoyable dining experience. For people with food sensitivities or health conditions who should avoid certain foods, such as milk, eggs, soy, wheat, or nuts, the comprehensive allergen guide is quite beneficial.
What is Sonic’s Allergen Menu?
The Sonic Allergen Menu provides comprehensive information about common allergens in Sonic food, including hamburgers, bread, fried foods, toppings, sauces, ice cream, and beverages. Any known allergens of each item in the menu list will be noted, as well as whether it possibly comes into contact with allergens due to shared equipment or preparation surfaces.
This menu allows you to make decisions on your orders, whether you are gluten intolerant, lactose sensitive, or nut allergic.

Important Advisory on Cross-Contact Risk
Despite all precautions that may have been taken, there is still a possibility of cross-contact occurring at Sonic locations, especially with fried foods using the same fryers. It’s likely that a product may come into contact with allergens during handling, cooking, or storage even if it isn’t listed. Sonic has not certified its kitchens to be allergy-free.
For people with severe or potentially fatal allergies, extreme caution is advised. You may also want to speak with your doctor before consuming these foods.

Sonic’s 2024 Allergen Menu states that the following items are 100% free of allergens and cross-contact:

Their hot dogs and burgers, such as the Jr. Chicago Dog and Burger, can be ordered without dairy by asking for no cheese. Note that the veggie burger contains dairy.
Burger buns are not necessary for the Chicken Slinger and Grilled Chicken Sandwich, which are dairy-free sandwiches, and Sonic wraps.
Breads like the standard burger and hot dog buns contain dairy, but brioche and foot-long buns do not.
Many sauces and condiments, such as BBQ sauce and tartar sauce, are also dairy-free, as are the majority of burger and sandwich meats.
Note: Cross-contamination with dairy can happen because of equipment used to prepare both, and ingredients differ by region, so always check at your local Sonic.
