Sonic Allergen Menu and Ingredients

Milk, soy and wheat run furthest down the Sonic allergen menu, reaching the SONIC Cheeseburger, the Chili Cheese Tots and every shake on the spindle. Egg covers every breakfast burrito and sandwich and rides in the mayo on the burgers. Sesame arrives with the bakery bun, while peanuts and tree nuts stay almost entirely inside the Blast freezer.

Each table on the Sonic allergen menu below pairs an item with the allergens named against it. One fryer bank, one soft-serve machine and one prep line stand behind all of it. Nothing handed through a car window arrives allergen-free.

Sonic allergen menu at a glance

Sonic Allergen Menu Item by Item

Every line on the Sonic allergen menu belongs to one item as it leaves the kitchen. The bun, patty, sauce and cheese that go into it all count toward the total. Sonic tracks ten names: egg, fish, milk, peanuts, sesame, shellfish, soy, tree nuts, wheat and gluten. Wheat and gluten move together on every row, and prices run down the Sonic price list.

A softer mark sits beside the hard ones, and a may-contain means shared handling reached the item rather than the recipe. The All-American Dog names soy and wheat outright, then adds may-contain marks on egg, milk and sesame from the bun it sits in.

Sonic Breakfast Allergens

Breakfast opens the Sonic allergen menu with Egg, Milk, Soy and Wheat on every burrito, TOASTER, bagel, biscuit and CroisSONIC build. Griddled egg, a flour tortilla and melted cheese put them there, and French Toast Sticks drop the egg while keeping the other three. All three BREAKFAST TOASTERs add a may-contain on sesame from the Texas toast. Brioche breakfast sandwiches, sold at some drive-ins, name sesame outright from the bun.

Sonic Burger and Smasher Allergens

A bakery bun sets the shape of the whole burger board, so Milk, Soy and Wheat read identically across all fourteen builds. Sesame names every build except the Grilled Cheese Burger, which carries only a may-contain. Egg is on all but the Quarter Pound Double Cheeseburger, and the American cheese slice brings the milk. The bun accounts for the sesame, the soy and the wheat between them.

Sonic Hot Dog and Coney Allergens

The Sonic allergen menu puts soy and wheat in the bun under every hot dog. Chili and shredded cheddar push milk onto the Chili Cheese Coney and the Footlong Quarter Pound Coney. Served plain, the All-American Dog holds to soy and wheat alone, though its bun still adds may-contain marks on egg, milk and sesame.

Sonic Chicken Tender and Sandwich Allergens

Sonic hand-breads its chicken and drops it straight into the fryer. Crispy Tenders name Egg, Soy and Wheat from the batter and nothing beyond it, and the Crispy Chicken Sandwich adds milk. That milk arrives with the breaded chicken breast rather than with anything spread on the bun. The Philly Cheesesteak, Pork Tenderloin Sandwich, both TOASTER sandwiches and both Queso Wraps all name milk and wheat.

Sonic Tots, Fries and Snack Allergens

Sonic Tots carry none of the ten declared allergens. Groovy Fries break that pattern, declaring wheat and gluten from their coating, while cheese sauce puts milk and soy on Cheese Tots. Ched ‘R’ Peppers and Mozzarella Sticks each declare milk, soy and wheat, and Onion Rings carry the same without the soy. The Corn Dog adds egg, as do both Groovy Fries builds.

Sonic Wacky Pack Kids Meal Allergens

Wacky Pack kids’ meals on the Sonic allergen menu carry the same Corn Dog and Crispy Tenders declarations as the main board. Jr. Burger declares Sesame, Soy and Wheat from its bun, and Grilled Cheese adds Egg and Milk to those three. The kids’ Hot Dog names soy and wheat with a may-contain on sesame, and Tree Top Apple Sauce declares none of the ten.

Sonic Shake Allergens

Real ice cream puts milk on every shake at the window. Soy follows it in through the caramel, hot fudge, chocolate and banana syrups, while vanilla and strawberry keep milk alone. The Peanut Butter Classic Shake names peanut outright, and the OREO Peanut Butter Master Shake carries a may-contain on it. All five Master Shakes add wheat.

Sonic Blast and Sundae Allergens

Mix-ins decide the Blast end of the Sonic allergen menu. Tree nuts name the HEATH and Turtle Truffle Nut builds, and both add a peanut may-contain. The REESE’S build names peanut outright, and the Chocolate Chunk Brownie Blast adds egg. Sundaes stay shorter, taking milk from the soft serve and soy from the caramel and hot fudge.

Sonic Slush, Limeade and Lemonade Allergens

Real lemon, real lime, cane sugar and the plain slush base build the limeade and lemonade line. Not one of the ten tracked names lands on a limeade, a lemonade or either half-tea, half-lemonade split. The Strawberry, Blue Coconut and Blood Orange Cream Slushes and the Lemonade Cream Cooler break that run by naming milk. Sonic squeezes the lime and lemon into every cup itself.

Sonic Soft Drink, Tea and Coffee Allergens

Sonic leaves fountain drinks, brewed tea and hot coffee clear from Coca-Cola through Ocean Water to Unsweet Iced Tea. Sonic pours flavour syrups into any of them, including the builds regulars name themselves. Milk enters only where it is poured in, on the two Cold Brew Iced Coffees and the 1% Milk. Plain water and the Minute Maid apple juice box read clear as well.

Sonic Ingredient Allergens

Sonic prints a separate line for each component that goes into a build, from breakfast breads and meats to patties, buns, sauces and slush flavours. The rows below follow that list, with each component’s group named before the colon. Each component declares its own allergens before anything is stacked on it, so a finished item can name more than one row. Where a component carries a softer may-contain mark, its row says so.

Dairy-Free Options at Sonic

Sonic allergen menu entries clear milk from forty-eight items, most of them drinks. Sonic’s dairy-free list leans heavily on the drink board. Twenty-four soft drinks, teas, coffees and juices skip milk entirely.

Fourteen limeades, lemonades, slushes and fizzes join them, including Limeade, Cherry Limeade and Strawberry Limeade. Four snacks also stay dairy-free: Tots, Groovy Fries, Soft Pretzel Twist and Pickle Fries. Crispy Tenders, Jumbo Popcorn Chicken and the Chicago Hot Dog round out the list. Three Wacky Pack picks join them: the Jr. Burger, the Hot Dog and Tree Top Apple Sauce.

Ordering Gluten-Free at Sonic

Sonic’s gluten-free list is built almost entirely from the drink menu. Twenty-seven soft drinks, teas, coffees and juices avoid wheat, and eighteen limeades, lemonades, slushes and Cream Slushes join them. Six shakes stay wheat-free too, among them Vanilla, Strawberry, Chocolate, Banana and Caramel Classic.

Eight Blasts, sundaes, floats and soft serve dishes round out the frozen treats without wheat. Tots, Cheese Tots and Queso cover the savory side of the list, and Tree Top Apple Sauce from the kids’ meals declares no wheat either.

Cross-Contact and Shared Equipment at Sonic

One fryer bank handles the tots, the tenders, the Corn Dog, the Onion Rings and the Ched ‘R’ Peppers. Sonic does not divide that oil by allergen. Soft serve, shakes and Blasts share the same spindles, cups and scoops. Nothing built to order at a drive-in is allergen-free, and no item is certified gluten-free.

Naming a serious allergy to the carhop before the order goes in covers the part a printed list cannot. It gives the crew a chance to change gloves, wipe down a spindle or move an item off shared equipment. A restaurant manager can also walk through how a specific build is put together.
