Sonic Allergen Menu, 2026

All 165 Sonic items checked against 7 common allergens.

Which Sonic items contain allergens?

Of the 165 items on the Sonic menu, 92 contain milk and 75 contain wheat, the two that run through nearly the whole board. Peanuts appear in 3 and tree nuts in 8, almost all desserts. 55 items flag none of the seven, overwhelmingly drinks.

Please read first. This list is worked out from each item's name and ingredients, not from Sonic's official allergen statement, and Sonic fries and prepares many of these items on shared equipment. An allergen that is not listed here is not a promise that the food does not contain it. If you have a serious allergy, check Sonic's own allergen guide and tell the drive-in before you order.

Straight answers

The Questions People Ask Most

The items people check before they order, answered from the same ingredients as the chart below.

Are Sonic tater tots gluten free?

No. The tots come out of the fryer with a battered coating, which is wheat, and they share their oil with the breaded chicken. Even a plain order of tots is not safe for celiac disease. See the Tots page.

Flags: Wheat, Soy

Are Sonic fries gluten free?

No. Groovy Fries are seasoned and battered rather than cut and fried plain, so wheat is in the fry itself, not only in the oil around it. Skipping the seasoning does not change that. See the Groovy Fries page.

Flags: Wheat, Soy

Are Sonic onion rings gluten free?

No. Sonic hand batters its rings, and that batter is the whole point of the item. This is the least ambiguous no on the fried side of the menu. See the Onion Rings page.

Flags: Wheat, Soy

Do Sonic mozzarella sticks contain dairy?

No. Mozzarella is the filling, so there is no version of this item without milk in it. The marinara it comes with is dairy free, but the stick is not. See the Mozzarella Sticks page.

Flags: Wheat, Milk, Soy

What We Track

The 7 Allergens to Watch For

Where each one hides on this particular menu, and how much of the board it takes with it.

Peanuts

In 3 of 165 items · 2%

Peanuts sit in the dessert menu, and the product name does not always admit it: REESE'S and Butterfinger are peanut products, and only the Peanut Butter shakes say so outright. Sonic blends these on shared equipment, so an item with no peanut in it is not the same as an item that never met one.

Tree Nuts

In 8 of 165 items · 5%

Tree nuts turn up in the Blasts and in the coconut slushes and creams. Coconut is counted as a tree nut here, which is the cautious reading and the one an allergy guide should take.

Wheat & Gluten

In 75 of 165 items · 45%

Wheat is the most common allergen on the Sonic menu. It lives in almost every bun and bread, in the batter on fried chicken, tots and onion rings, and in tortillas, biscuits, croissants, and cookie-based desserts.

Milk & Dairy

In 92 of 165 items · 56%

Dairy appears anywhere there is cheese, ice cream, or a creamy sauce. That covers cheeseburgers, shakes, Blasts, sundaes, and toppings like ranch. Most of the dessert menu contains milk.

Egg

In 33 of 165 items · 20%

Egg is really a breakfast problem here. Most of the items flagging it are breakfast, where egg is the filling rather than an ingredient, and the rest are burgers and sandwiches carrying a mayo-based sauce. Order off the main board after breakfast and egg largely stops being a question.

Soy

In 41 of 165 items · 25%

Soy follows the fryer and the bun. It is in the frying oil, so the whole tots and onion rings side of the menu carries it, and in the breading on the chicken, and it turns up again in the buns underneath the burgers. Soy is the hardest of the seven to eat around without leaving the food menu entirely.

Pork

In 26 of 165 items · 16%

Pork on this menu means bacon and sausage, nothing else, and it sits almost entirely in breakfast. On the main board it is an add-on rather than the item itself, so a bacon burger ordered without the bacon is a burger. That makes pork the one allergen here you can usually remove at the speaker.

Plant-based

Vegan Options at Sonic

Sonic has no vegan menu and no plant-based patty, so vegan ordering here means the items whose ingredients carry no meat, no dairy and no egg. That is 62 of the 165 items, and all but 4 of them are drinks.

The food

Only 4 items you can chew qualify, all of them fried sides. They share a fryer with battered chicken, so they are vegan by recipe rather than by preparation.

Ched 'R' Bites Groovy Fries Onion Rings Tots

The drinks

The rest of the vegan list is the drink menu: the limeades, slushes, teas and fountain sodas. Anything with soft serve in it, the shakes, Blasts, sundaes and cream slushes, is out.

58 drinks qualify. See the full drinks menu.

Avoiding Peanuts?

162 picks without it

162 of the 165 items do not flag peanuts, against 3 that do. The list is long because peanuts barely appear here, but the shakes and Blasts are blended on shared equipment, so treat the whole dessert counter as one risk rather than reading it item by item.

Avoiding Tree Nuts?

157 picks without it

157 of the 165 items do not flag tree nuts, against 8 that do. Coconut is counted as a tree nut here, so this list is shorter than a list drawn up by someone who does not count it. If your allergy does not extend to coconut, the blue coconut drinks come back onto it.

Avoiding Wheat & Gluten?

90 picks without it

90 of the 165 items do not flag wheat & gluten, against 75 that do. Read this one as a starting point and not a gluten-free menu. Sonic runs no dedicated fryer, so anything cooked in oil here has been in wheat, whatever its own recipe says.

Avoiding Milk & Dairy?

73 picks without it

73 of the 165 items do not flag milk & dairy, against 92 that do. This is the shortest list on the page, and most of what is left is a drink. A cheeseburger ordered without cheese lengthens it considerably, which the chart cannot show you.

Avoiding Egg?

132 picks without it

132 of the 165 items do not flag egg, against 33 that do. Almost everything missing from this list is breakfast. Order after the breakfast window closes and the problem mostly solves itself, though mayo-based sauces on the main board still carry egg.

Avoiding Soy?

124 picks without it

124 of the 165 items do not flag soy, against 41 that do. Soy sits in the frying oil rather than in a recipe, so this list is the least reliable of the seven. If you react badly to soy, the drinks are the only part of the menu worth trusting without asking.

Avoiding Pork?

139 picks without it

139 of the 165 items do not flag pork, against 26 that do. Bacon and sausage are usually add-ons rather than the item, so several things not on this list join it the moment you ask for them without. Halal preparation is a separate question and this guide does not answer it.

Meat-Free

Vegetarian Options on the Sonic Menu

Sonic does not offer a plant-based burger at most locations, so the vegetarian side of the menu leans toward sides, drinks, and sweets. These 109 picks are meat-free.

How to Order at Sonic With a Food Allergy

Say it at the speaker, then say it again at the car. Ordering from a stall means your allergy goes into an intercom and gets relayed to someone you never see. The carhop bringing the tray out is the last point where you can check, and asking again there costs nothing.

Use the app if the allergy is a serious one. Customisations you tap reach the kitchen written down rather than heard through a speaker box, and you get to read the order back before you pay instead of after you have pulled away.

Treat the fryer as shared, because it is. Tots, Groovy Fries, onion rings, mozzarella sticks and the battered chicken all go into the same oil, so a side carrying no wheat of its own still comes out of a wheat fryer. That is the reason nothing fried here works for celiac disease.

Cheese is the biggest single thing you can take off. Milk is flagged on 92 of the 165 items, further than any other allergen on this page reaches, and much of that is a slice on a burger or soft serve in a cup. Ordering without cheese or a creamy sauce clears a lot of it in one move.

If you want certainty rather than a shorter list, it sits at the drink end of the menu. 55 items flag none of the seven and nearly all are drinks: water, coffee, the limeades, the slushes, the fountain sodas. Past that, Sonic publishes its own allergen guide, and anywhere it disagrees with this page, it is right and this page is not.

Your Questions

Sonic Allergen Menu: Common Questions

Does Sonic have an allergen menu?

Sonic publishes allergen and nutrition details on its own website and in the Sonic app, and that is always the final word. This page is an independent guide: it checks all 165 items on the menu against 7 common allergens so you can see the shape of the menu before you order.

What are the most common allergens at Sonic?

Milk and wheat, by a distance. Milk appears in 92 of the 165 items on the menu (56%) and wheat in 75 (45%), because cheese, ice cream, buns and breading run through nearly everything. Soy is in 41, egg in 33 and pork in 26.

Does Sonic have peanut-free options?

Only 3 items on the menu contain peanuts and 8 contain tree nuts, almost all of them Blasts, shakes and coconut drinks. But Sonic blends desserts on shared equipment, so an item with no peanut in the recipe is not the same as an item that never met one. For a serious peanut allergy, tell the drive-in before you order.

Does Sonic have gluten-free options?

Sonic does not market a gluten-free menu. 75 of the 165 items flag wheat, which leaves 90 that do not, mostly drinks, slushes and plain sides. Most cooked items share fryers, so anyone with celiac disease should treat that as cross-contact risk and confirm with the restaurant.

Is there anything dairy-free at Sonic?

73 of the 165 items do not flag milk, which is most of the drink and slush menu plus some plain fried sides. Ordering a burger without cheese or sauce removes another common source, though sauces and seasonings can still hide dairy.

Does Sonic have vegan options?

62 of the 165 items carry no meat, dairy or egg in their ingredients, but only 4 of those are food rather than a drink: the tots, Groovy Fries, onion rings and Ched 'R' Bites. Sonic has no vegan menu and no plant-based patty, and the fried sides share oil with battered chicken.

Are Sonic tater tots gluten free?

No. The tots are battered, so they flag wheat, and Sonic fries them in shared oil alongside battered chicken and onion rings. The same is true of the Groovy Fries. Neither is safe for celiac disease.

Which Sonic items are vegetarian?

109 of the 165 items look vegetarian by their ingredients: the tots, fries, onion rings and mozzarella sticks, nearly all the drinks and slushes, and the ice-cream desserts. Sonic does not carry a plant-based patty at most drive-ins, so the vegetarian side leans to sides and sweets.

Are there Sonic items with no common allergens at all?

55 of the 165 items flag none of the seven allergens tracked here. They are overwhelmingly drinks: water, coffee, the limeades, the slushes and the fountain sodas.

Can Sonic accommodate a food allergy?

Most items can be changed at the stall: cheese off, sauce off, no bun, toppings dropped. What Sonic cannot change is the equipment, and the fryers and prep surfaces are shared, so cross-contact stays on the table however the order is written. For a serious allergy, say so at the speaker and again to the carhop.

Is the allergen information on this page official?

No. It is worked out from each item's name and ingredients, not from Sonic's own allergen statement. An allergen missing from this chart is not a promise the food does not contain it. For medical-grade accuracy, check Sonic's official allergen information and speak to the restaurant.

Check Any Item's Full Details

Every one of the 165 items has its own page, with what it contains, what it costs and what the nutrition looks like.

This allergen guide is a general, unofficial overview based on typical ingredients and is not a substitute for Sonic's official allergen information. Recipes, suppliers, and preparation vary by location and over time, and shared equipment can cause cross-contact. Anyone with a serious food allergy should confirm details directly with Sonic before ordering.
