Are French Fries Gluten-Free?

The short answer? Yes. Fries are made from potatoes, which are naturally gluten-free. They’re also typically baked or deep-fried in oil (which is another gluten-free ingredient).

But gluten in french fries boils down to two things: ingredients and preparation.

For example, beer-battered french fries are on the “naughty list” since most beer contains glutinous wheat, rye, or barley. Many seasoned varieties are also on that list because their seasoning includes gluten. Furthermore, some restaurants coat their fries in wheat flour to make them crispier.

At home, it’s easy to make your french fries gluten-free. But in the outside world, cross-contamination is a major concern. Some restaurants fry french fries in a deep fryer alongside breaded items like chicken tenders, mozzarella sticks, and onion rings. If that’s the case, the oil will be contaminated with gluten.

Your best course of action is to double-check at every fast-food restaurant and specifically ask staff whether the fries are prepared in an exclusively gluten-free fryer.

The good news is that many fast-food chains are adapting and using separate gluten-free fryers nowadays. You can even get gluten-free burgers and fries at Disneyland!

Which Fast Food French Fries Are Gluten-Free?

No matter where you are in the world, it pays to ask staff before ordering your meals. Many fast-food restaurants and chains have hopped on the gluten-free train and use dedicated gluten-free fryers for their fried items, including:

Hopdoddy Burger Bar: Yes, they cook their fries in a separate fryer.
Red Robin: You’ll need to put in a request but staff will cook their famous steak fries in their dedicated gluten-free fryer.
In-N-Out Burger: Rejoice! This popular chain cooks their gluten-free french fries in a separate fryer using sunflower oil.
Ted’s Montana Grill: I bet you’re glad to know that their delicious hand-cut fries are cooked in a dedicated fryer.
Five Guys Burgers & Fries: They cook their hand-cut fries in a dedicated fryer using peanut oil.
Chick-Fil-A: They cook their signature waffle fries in a separate fryer using peanut oil.
Honest Burger: This is a popular UK chain. Their french fries and onion rings are cooked in the same separate gluten-free fryer.
Larkburger: For Colorado locals here, Larkburger also offers onion rings and fries cooked in the same dedicated gluten-free fryer.

However, some chain locations have separate fryers and others don’t. Be sure to double-check when you go to the following restaurants:

Burger King
Dairy Queen
Wendy’s
Sonic Drive-Thru (Note: Ask staff as most stores have a dedicated gluten-free fryer for their fries and tater tots).

Which Fast Food French Fries Aren’t Gluten-Free?

There are plenty of places to get your gluten-free fries fix, but several fast food restaurants cook theirs in a shared fryer. If you’re on the hunt, avoid these places:

McDonald’s (sorry, folks).
A&W
KFC (basically their entire menu includes gluten).
Popeye’s (see above).
Shake Shack
Raising Cane’s
Smashburger
Arby’s
Carl’s Jr.
Hardee’s
Culver’s
White Castle
Whataburger

We’ve determined above which of your favorite fast-food joints may offer gluten-free french fries. But here’s a quick hit list:

Do McDonald's Fries Have Gluten?

Are McDonald’s fries gluten-free? Unfortunately, no. McDonald’s cooks theirs in a shared fryer, alongside other glutinous items (like their chicken nuggets). This means they’re not suitable for people on a strict gluten-free diet.

Are Burger King Fries Gluten-Free?

Some Burger King fries are gluten-free. You’ll need to confirm with the individual outlet whether a separate gluten-free fryer is used. Some do and some don’t.

Are KFC Fries Gluten-Free?

KFC is one of the least gluten-friendly fast-food restaurants. Their fries are cooked in a shared fryer with the fried chicken. In fact, the only available gluten-free items are sides like green beans, coleslaw, potatoes, and corn.

Which Frozen French Fries Are Gluten-Free?

These days, there are plenty of gluten-free fries to make at home, thanks to these brands.

Ore-Ida

Ore-Ida is our top pick. Available in most grocery stores, they label their frozen french fries as gluten-free. Spoiler: Their tater tots are also labeled gluten-free. You’re welcome!

McCain Foods

You’ll find McCain fries in restaurants worldwide. In fact, McCain takes credit for one out of every three french fries consumed around the world. While they don’t label their products as gluten-free, their product labels clearly state whether any ingredients contain gluten. Just keep your eyes peeled.

Focus on their traditional fries (including classic-cut, crinkle-cut, smiles, and steak-cut fries). None of these include gluten-containing ingredients. You’ll want to avoid the seasoned, extra crispy, and beer-battered fries. These include either wheat flour or barley.

Grown In Idaho

Grown in Idaho frozen french fries don’t contain added gluten, but because they’re produced in a shared facility, they can’t be labeled as gluten-free. However, their packaging always states whether there are any traces of gluten. Do a double-check before picking up your next packet.

Red Robin

Red Robin frozen french fries don’t contain gluten or a wheat allergen statement. Because of shared facilities, they can’t officially be labeled as gluten-free.

Cascadian Farm

Cascadian Farm is well-known for its organic products. They offer crinkle-cut and straight-cut french fries, as well as shredded potatoes and sweet potatoes. While each product is organic, non-GMO, and gluten-free, because of shared facilities they aren’t labeled gluten-free.

Kroger

You’ll want to avoid their seasoned frozen fries as they do contain wheat. On the flip side, their plain fries are gluten-free.

Alexia Foods

While Alexia Foods frozen french fries are made in a shared facility, they’re prepared on dedicated gluten-free equipment. According to their website, if the product contains any gluten, “it will be called out on the packaging after the ingredient list. If you have an allergy or sensitivity, we'd suggest checking the packaging each time you purchase it for the most recent list of ingredients and information.”

Tips to Avoid Cross-Contamination of French Fries

Here are some tips to help you on your gluten-free journey:

At home, have a dedicated gluten-free area. It should be stocked with clean cooking equipment and utensils.
At the grocery store, double-check the frozen fries package. If there’s a gluten-free label or no traces of gluten, you’re good to go.
When dining out, always voice your concerns. Ask whether the fries are cooked in a shared fryer with other breaded items. If the answer is yes, stick to non-fried food (if possible).
Request pre-packaged condiments when dining out. This allows you to read the label and double-check there’s no gluten.
