Eating out gluten free

The short answer

Restaurant risk is mostly not about the menu. It is about shared fryers, shared pasta water, shared grills, flour in the air, and the gap between "gluten free" as a menu label and "gluten free" as a kitchen practice.

A published study found that a substantial share of restaurant food ordered as gluten free tested positive for gluten, with pizza and pasta the worst offenders by a wide margin.

The rule: the menu tells you about ingredients, not about the kitchen

Fried food is the most reliable failure. Oil that has fried anything breaded carries gluten, and french fries cooked in that oil are not gluten free no matter what the potato started as. "Do you have a dedicated fryer?" is a more useful question than anything about the menu.

Pizza is the second. A gluten-free crust assembled on a floured bench, cut with the same wheel, and baked on the same stone as wheat pizza has been through three separate contact events. Some pizzerias handle this well with a separate prep area and a screen. Most do not, and the difference is not visible from the dining room.

It helps to be specific without being confrontational: "I have celiac disease, so this is a medical thing rather than a preference. Can you check with the kitchen whether this can be made without cross-contact?" Staff respond to "medical" very differently from "gluten free," and the phrase "cross-contact" signals that you mean the process rather than the recipe.

Timing helps more than people expect. Early service, before the fryer has been used and while the line is clean, is measurably lower risk than the middle of a rush.

At a glance

Sorted by what the answer actually is, rather than alphabetically — because the useful question in a shop is “which pile is this in.”

⛔ Contains gluten

Shared fryer
The most common single point of failure. Applies to fries, chips and anything battered.
Shared pasta water
Gluten dissolves into the water and transfers.

⚠️ Depends — check the label

Gluten-free pizza in a wheat pizzeria
Flour dust, shared bench, shared cutter, shared stone. Ask about all four.
Grilled meat and fish, plain
Usually fine; the marinade and the grill surface are the questions.
Salad without croutons
Removing croutons from a salad that had them does not remove the gluten. Ask for it made fresh.
Corn tortillas at a taqueria
Naturally gluten free, but often warmed on the same surface as flour tortillas.
Sushi
Soy sauce, imitation crab, tempura crunch and eel sauce all carry gluten.
Breakfast eggs
Pancake batter on a shared griddle is a real route; some kitchens add batter to omelettes.

✓ Gluten free

Dedicated gluten-free kitchen
The only setup where cross-contact is structurally impossible.

Common questions

What should I ask a restaurant about gluten?

Three questions cover most of the risk: is there a dedicated fryer, is there a separate prep surface and separate utensils for gluten-free orders, and is gluten-free pasta cooked in fresh water. Saying "I have celiac disease" rather than "I eat gluten free" changes how kitchens respond.

Are french fries gluten free?

The potato is, but the oil usually is not. A fryer shared with breaded food carries gluten into everything cooked in it. Some fries are also coated with a wheat-containing batter for crispness before freezing.

Can I trust a restaurant gluten-free menu?

A gluten-free menu tells you the recipe contains no gluten ingredients. It says nothing about shared equipment, and testing studies have found a meaningful share of restaurant food ordered as gluten free contains detectable gluten, concentrated in pizza and pasta. Treat the menu as the start of the conversation rather than the end of it.

The scanner

Reading a page is fine. Standing in the aisle is the hard part.

This site answers the question you knew to ask. The app answers the one you didn't: the barley malt in a rice cereal, the wheat starch in a gummy. Scan the barcode, or photograph the panel when the barcode isn't in any database, and CiCi shows which words on the label produced the answer.

360,000+ packaged foods already read. Ingredient statement, allergen declaration and nutrition panel, each one assessed by the same rules you can see working on this page, so most scans are an instant answer rather than a lookup.
Unlimited scanning, about two seconds an answer. Fig and Spoonful both cut you off at five scans a month.
Carbs and the full nutrition panel on every scan. Total and net carbohydrate with the arithmetic shown. For the roughly 6% of people with type 1 diabetes who have coeliac disease too, that is two apps collapsed into one.
Your glutening log. Record a reaction and CiCi shows what those days had in common. It counts overlaps and never tells you what caused it.
Saved products. The regular shop in one place, so next week is not a re-scan of the same forty items.
Scanning happens on your device. No scan is ever attached to you, sold, or sent to an analytics service.

Other food categories

Gluten-free breadThe bread aisle is where the most gluten exposures start. More of its marketing language sounds health-adjacent than in any other category, and none of that language means gluten-free.Gluten-free beerThis is the one category where a legal label distinction maps onto a real medical distinction, and almost nobody explains which is which.Gluten-free soy sauceSoy sauce is the highest-frequency accidental exposure in restaurant eating, because it is in almost everything and almost nobody thinks of it as a wheat product.Gluten-free oatsOats are the only common food where the correct answer depends on which country you are standing in, and where a meaningful minority of people react even to perfectly clean oats.Gluten-free candyCandy is a good category to learn on, because it is small, the failure modes are few, and they recur everywhere else.Gluten-free sauces and condimentsA meal built entirely from naturally gluten-free ingredients is routinely undone at the last step by a spoonful of something from a jar.Gluten-free pastaThe noodle aisle is unusually forgiving once you know which base grain you are looking at, with one systematic exception.Gluten-free breakfast cerealCereal is the clearest demonstration of why an ingredient-list scanner that only looks for the word "wheat" is dangerous.Gluten-free flourFlour is the category where a naturally gluten-free ingredient most often arrives contaminated, because milling equipment is expensive and rarely dedicated.Gluten in medications and supplementsThis is the category where the honest answer is most often "ask the manufacturer," and where scanners that give a confident verdict are least defensible.Gluten-free snacksA category where the base food is nearly always safe and the flavouring nearly always decides the answer.Gluten-free dairy and cheeseDairy is one of the safest aisles in the shop, which is why the few exceptions catch people off guard.Gluten-free meat and deliThis is the aisle where the regulatory technicality has real consequences, and almost no consumer guide mentions it.Gluten-free coffee, tea and drinksA category where the base drink is almost always fine and the additions decide the answer.Gluten-free bakingIn baking, the gluten-free question is less about safety and more about how a batter holds together without gluten.Gluten free for kids and schoolWritten for parents, and more about systems and social situations than about ingredient lists.Gluten free travelThe most useful travel tip is that a good translation card explains cross-contact rather than just naming gluten.Gluten-free frozen and convenience foodThe freezer aisle is where a naturally gluten-free food most often arrives with something added that nobody would have predicted.Gluten in cosmetics and household productsThis category is dominated by marketing, and the honest version saves people a great deal of unnecessary expense and worry.
