βKey Takeaways
In the world of fast-food burgers, celiacs are usually stuck eating a sad, dry patty with a knife and fork after throwing away the bun.
But Five Guys is different. Their simple, transparent menu and dedicated frying process make them arguably the most celiac-friendly burger chain in America.
Here is why Five Guys is a safe haven.
The Fries: Dedicated Fryer β
This is the single most important reason Five Guys stands out.
Five Guys only fries their French Fries. They do not fry breaded chicken, mozzarella sticks, or onion rings. The fryer contains only potatoes and pure peanut oil.
* The Result: Because there are no breaded, wheat-containing products going into the fryer, the oil is NOT contaminated with gluten. The fries are naturally safe for celiacs.
* The Cajun Fries: The Cajun seasoning is also gluten-free. You can safely enjoy the Cajun Fries.
*(Note: Five Guys does NOT label their fries as "Gluten-Free" because the fries are processed in a shared facility before arriving at the restaurant. However, the in-store fryer itself is free from wheat cross-contamination, making it a very low risk for most celiacs.)*
The Burger: Lettuce Wrap β
Five Guys uses standard wheat hamburger buns. You cannot eat the bun.
The Solution: Five Guys will gladly wrap your burger in fresh lettuce leaves instead of a bun. Just order your burger "Lettuce Wrap" or "Bowl Style."
* All burger toppings (lettuce, tomato, onion, pickles, jalapeΓ±os, mushrooms, green peppers) are naturally GF.
* The Cheese: American cheese, which Five Guys uses, is naturally GF.
* The Bacon: Five Guys bacon is naturally GF.

The Danger Zone β
There are a few items to avoid:
* The Bun: Obviously, the standard sesame seed bun is pure wheat.
* The Hot Dogs: The hot dog itself is GF, but the bun is wheat. Order it without the bun.
* The Grilled Cheese: This is literally a bun filled with cheese. Do not eat it.
* The Milkshakes: β οΈ Five Guys milkshakes use mix-ins. If you add Oreo cookies or Malted Milk Powder, it is contaminated. Stick to plain vanilla or chocolate shake with safe mix-ins (like peanut butter or banana).
π½οΈ Eating out and unsure what to ask?
Scan a menu item or label and get the exact questions to ask your server about sourcing and shared equipment β no awkward guesswork.
The Cross-Contamination Caveat β οΈ
While Five Guys is incredibly safe compared to other chains, there is one caveat.
The workers handle wheat buns with their gloved hands and then may handle your lettuce-wrapped burger without changing gloves.
The Protocol: When you order, say: *"I have a severe wheat allergy. Could you please change your gloves before preparing my lettuce-wrapped burger?"*
Summary: Five Guys is a celiac's best friend in the fast-food burger world. The dedicated peanut oil fryer makes the fries genuinely safe, and the lettuce wrap is a delicious, filling alternative to the bun. Use the Check Gluten web app to verify any seasonal sauces!

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten β a protein found in wheat, barley, and rye β triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Cross-contamination
- Cross-contamination (or cross-contact) occurs when gluten-free food comes into contact with gluten-containing food or surfaces β such as shared cutting boards, toasters, fryers, or utensils β rendering otherwise safe food dangerous for people with celiac disease.
