Gluten-free restaurant guides

Gluten-free fast food, ranked for celiac

Plenty of fast food is gluten-free on paper. For celiac, what matters is the kitchen: shared fryers, shared grills and how staff handle an allergy. This list grades 27 chains the way Sift grades them for a strict celiac eater, best first.

1. Chick-fil-ACeliac grade A
One of the most celiac-friendly fast-food chains: a sealed gluten-free bun, grilled nuggets/filets, and waffle fries cooked in a dedicated canola fryer.
Dedicated fryer · Gluten-free menu
2. Five GuysCeliac grade A
Fries are cooked in 100% peanut oil with nothing breaded, and a bunless burger is easy. The flat-top grill is shared with buns, so there's some surface risk.
Dedicated fryer · Gluten-free menu
3. In-N-OutCeliac grade A
A surprise standout. Order any burger 'Protein Style' (lettuce wrap) and the fries are fresh-cut potatoes cooked in a dedicated fryer with nothing breaded.
Dedicated fryer
4. El Pollo LocoCeliac grade B
The core is naturally gluten-free: citrus fire-grilled chicken, rice, beans, salsas, and many bowls. Shared kitchen without dedicated GF utensils, but the flame-grilled model means lots of safe-by-ingredient choices.
Dedicated fryer · Gluten-free menu
5. Firehouse SubsCeliac grade B
Offers a gluten-free sub roll and a salad option. Steamed-meat prep and a bread-heavy shop mean cross-contact is possible.
Dedicated fryer · Gluten-free menu
6. Jersey Mike'sCeliac grade B
Offers gluten-free bread and a 'sub in a tub' (bowl) option, and they'll change gloves and clean the slicer area on request. Flour-dusted shop means some risk.
Dedicated fryer · Gluten-free menu
7. Shake ShackCeliac grade B
Offers gluten-free buns and the crinkle-cut fries are cooked in a dedicated fryer. The griddle is shared, so a glove change and clean spot help.
Dedicated fryer · Gluten-free menu
8. Culver'sCeliac grade C
Has a published gluten-free guide and a gluten-free bun. Fries and cheese curds share a fryer with breaded items, so fried food is off-limits if you react to cross-contact.
Shared fryer · Gluten-free menu
9. Jimmy John'sCeliac grade C
The 'Unwich' wraps any sub in lettuce instead of bread. No fryer, but the shop is full of bread flour, so cross-contact is possible.
Dedicated fryer
10. Domino'sCeliac grade D
Sells a gluten-free crust, but Domino's explicitly states it's NOT recommended for celiac — pizzas are prepped in a shared, flour-heavy kitchen.
Shared fryer · Gluten-free menu
11. WhataburgerCeliac grade D
Has a gluten-free bun and an allergen guide. Fries share a fryer with breaded items, so skip them if cross-contact is an issue.
Shared fryer · Gluten-free menu
12. Arby'sCeliac grade F
Famous for sliced meats, but there's no GF bun, the curly fries share a fryer, and most items are bread-based. A meat-and-toppings plate is about it.
Shared fryer
13. Dairy QueenCeliac grade F
Soft-serve and many Blizzards (with GF mix-ins) are fine, and a bunless burger works. Everything fried shares oil.
Shared fryer
14. Del TacoCeliac grade F
Some corn-tortilla and bowl options work, but there's a shared fryer and shared prep, and no dedicated GF menu.
Shared fryer
15. Papa JohnsCeliac grade F
Has offered a gluten-free crust, but the shared kitchen and flour mean it's positioned for gluten-avoiders, not celiac.
Shared fryer · Gluten-free menu
16. Pizza HutCeliac grade F
Offers a gluten-free Udi's crust at participating locations, but the shared kitchen means it isn't suitable for celiac.
Shared fryer · Gluten-free menu
17. Sonic Drive-InCeliac grade F
Has an allergen guide but a shared fryer and no GF bun. Bunless burgers, hot dogs without the bun, and many drinks/slushes work.
Shared fryer
18. Taco BellCeliac grade F
Publishes ingredient info and has options (Power Menu Bowl), but there's no GF certification, shared prep, and a shared fryer.
Shared fryer
19. The Habit Burger GrillCeliac grade F
Publishes a celiac/GF reference but offers only lettuce wraps (no GF bun), so a Charburger 'protein style' is the main path. Fries share a fryer with breaded items — a sensitivity-level choice.
Shared fryer · Gluten-free menu
20. Wendy'sCeliac grade F
No GF bun and a shared fryer, but a baked potato and chili give you real, non-fried options.
Shared fryer
21. Burger KingCeliac grade F
No GF bun and a shared fryer. A flame-grilled patty without the bun or a garden side salad are your only real options.
Shared fryer
22. McDonald'sCeliac grade F
No gluten-free bun in the US and a shared fryer for everything. Slim pickings — mostly a bunless patty or a salad.
Shared fryer
23. Panda ExpressCeliac grade F
Most dishes use soy sauce (wheat) or are battered/fried, and woks/utensils are shared. Only a couple of items are gluten-free and cross-contact is high.
Shared fryer
24. KFCCeliac grade F
Built around breaded fried chicken with shared oil. Almost nothing is safe beyond a couple of plain sides.
Shared fryer
25. PopeyesCeliac grade F
Like KFC — breaded, fried, shared oil. Very little is gluten-free and cross-contact is everywhere.
Shared fryer
26. Raising Cane'sCeliac grade F
The whole menu is breaded chicken fingers, fries, and Texas toast — all gluten or shared fryer. Effectively nothing safe.
Shared fryer
27. WingstopCeliac grade F
Classic (bone-in) wings are naturally gluten-free, but they're fried in shared oil with breaded boneless wings and fries.
