For guests with food allergies, eating at fast-food restaurants can feel stressful — but the Sonic Allergen Menu helps provide clarity on what menu items contain, may contain, or can come into cross-contact with major allergens. Today, more families than ever are managing allergies to milk, egg, gluten, soy, peanuts, tree nuts, sesame, shellfish, and fish, making it essential to have accurate, trustworthy information before placing an order.

Sonic Drive-In has modernized its allergen transparency in recent years, offering a detailed breakdown of every category on the menu — from breakfast burritos and burgers, to chicken tenders, hot dogs, sides, slushes, shakes, and Wacky Pack® kids meals. While Sonic cannot guarantee a completely allergen-free environment due to its shared cooking equipment, the brand provides extensive guidance so customers can plan ahead, avoid high-risk items, and choose meals that align with their dietary restrictions.

⭐ Understanding Sonic’s Allergen Classification

Sonic identifies allergens in three ways:

✔ CONTAINS – The item definitely contains the allergen

The allergen is a direct ingredient (e.g., milk in cheese, wheat in buns).

✔ MAY CONTAIN – Possible presence of the allergen from suppliers

Minimal but possible exposure due to shared manufacturing.

✔ RISK OF CROSS-CONTAMINATION – Occurs due to kitchen operations

Because Sonic uses shared cooking equipment (fryers, grills, prep areas), ANY item could come into contact with allergens.

This guide rewrites the information into user-friendly tables, helpful breakdowns, and parent-focused explanations.

⭐ Major Allergens Tracked in This Guide

Sonic tracks and categorizes the following:

• Egg
• Fish
• Milk / Dairy

⭐ Understanding Cross-Contamination at Sonic

Sonic clearly states:

❗ There is ALWAYS risk of cross-contact for all allergens.

Why?

• Fried foods share the same fryers
• Grills cook items with milk, egg, soy, wheat
• Bun oil contains soy, touching nearly all grilled items
• Desserts share the same mixing tools
• Local bakeries supply buns that may contain sesame

Examples:

• A gluten-free safe item may still contain bread crumbs from fryers
• Peanut-based Blasts can cross-contact with other frozen desserts
• Eggs cooked on grills may touch bread residue

Parents and highly sensitive diners should take note.
