Sonic French fries are a popular menu item at the American fast food restaurant chain Sonic Drive-In. With their crispy exterior and fluffy interior, Sonic’s fries have become a staple side for burgers, hot dogs, and other entrees. But for those with dietary restrictions, such as a dairy allergy or vegan diet, an important question arises: Do Sonic French fries contain milk or other dairy ingredients?
The Ingredients in Sonic French Fries
According to Sonic’s website, the ingredients in their traditional French fries are:
- Potatoes
- Vegetable oil (canola, soybean, and/or sunflower oil)
- Natural beef flavor [wheat and milk derivatives]
- Dextrose
- Sodium acid pyrophosphate (maintain color)
- Extractives of paprika (color)
- Citric acid (preservative)
The main ingredients are relatively straightforward – potatoes, oil, and basic seasonings for flavor. The key ingredient to note is “natural beef flavor.” According to Sonic, this beefy flavoring contains milk derivatives. So yes, Sonic’s traditional French fries do contain some form of dairy.
Why Dairy is Added to French Fries
You may be wondering why a non-dairy product like French fries needs to contain dairy ingredients at all. Dairy derivatives are often added to foods like French fries for the following reasons:
- Flavor – Ingredients like milk solids or whey add a creamy, rich taste that enhances other flavors.
- Browning – Milk proteins help promote browning and crisping during frying or baking.
- Texture – Dairy ingredients can alter the crispness and tenderness of the exterior and interior of fries.
- Adhesion – Milk proteins act as a “glue” that makes seasonings and flavorings stick better to foods.
For companies like Sonic, the dairy components in their fry seasoning helps boost the flavor, color, and texture of their fries to match their signature Sonic taste and consistency.
Are There Dairy-Free Options?
For consumers avoiding dairy, the presence of milk derivatives in Sonic fries may be disappointing. However, Sonic does offer some dairy-free French fry options:
Tater Tots
Sonic’s tater tots do not contain any dairy ingredients in their seasoning. According to Sonic’s website, tater tots only contain:
- Potatoes
- Vegetable oil (canola, soybean, and/or sunflower oil)
- Dextrose
- Sodium acid pyrophosphate (maintain color)
- Extractives of paprika (color)
- Citric acid (preservative)
So for a dairy-free fried potato side, tater tots are the way to go.
Sweet Potato Tots
Sonic’s sweet potato tots also do not contain milk ingredients. The sweet potato tots contain:
- Sweet potatoes
- Vegetable oil (canola, soybean, and/or sunflower oil)
- Dextrose
- Sodium acid pyrophosphate (maintain color)
- Spices
- Yellow corn flour
- Citric acid (preservative)
- Extractives of paprika (color)
The sweet potato tots offer a dairy-free, veggie-packed alternative to traditional French fries.
Ask for Fries Without Seasoning
Finally, Sonic states that customers can request French fries without seasoning. These plain fries would only contain potatoes, oil, and likely salt – making them safe for those avoiding dairy.
However, this option means missing out on Sonic’s signature fry flavor that makes their fries stand out from competitors. It also means the fries may have less appealing color and texture, since the milk-based seasoning boosts these qualities.
Are Other Sides Dairy-Free?
In addition to potato sides, Sonic’s menu features some other dairy-free side options including:
Onion Rings
Sonic’s breaded onion rings do not contain dairy ingredients. They’re made with onions, wheat flour, yellow corn flour, sugar, salt, dried garlic, dried onion, spices, leavening (baking soda, sodium aluminum phosphate, monocalcium phosphate) and yeast.
Fried Pickles
Sonic’s fried pickles are another dairy-free choice. The ingredients are pickle slices, wheat flour, yellow corn flour, corn starch, salt, dried garlic, citric acid , spices, leavening (sodium acid pyrophosphate, sodium bicarbonate) and yeast.
Corn Dog (No Cheese)
A regular Sonic corn dog without cheese contains no dairy. It’s made of pork and chicken hot dogs plus a corn dog batter of water, enriched wheat flour, wheat flour, yellow corn flour, sugar, leavening (baking soda, sodium aluminum phosphate), salt, corn starch, rice flour, garlic powder, spices, paprika, extractives of paprika, and citric acid.
Just be sure to order without the cheese topping, which would add dairy.

Dining Out Dairy-Free
If you need to avoid dairy, dining out at fast food restaurants like Sonic can be tricky. Here are some tips to stay dairy-free:
- Check ingredient lists online before ordering.
