Is pad thai gluten free?

A part-by-part look at pad thai, from the noodles to the sauce, with the questions that decide whether your plate is gluten free.

Short answer

It can be, if the sauce, any marinade and the wok all check out. Pad thai starts from rice noodles, which are almost always gluten free, plus tamarind, fish sauce and egg, which are naturally gluten free. Sauces differ, though: one bottled vegan pad thai sauce lists soy sauce made with wheat. Ask about the sauce, the marinade and the wok, and let the kitchen confirm.

The menu at a glance

Usually fine
  • Rice noodlesThe base of pad thai, and almost always gluten free. Ask the server to confirm the kitchen uses rice noodles for it.
  • Tamarind and fish sauceThey give the sauce its tart and salty taste, and both are naturally gluten free. Ask whether anything else goes into the sauce.
  • Scrambled eggMixed into the noodles in the wok. Eggs on their own are naturally gluten free.
  • Bean sprouts, peanuts and limeStir-fried in, squeezed over or sprinkled on top. Fresh vegetables, legumes and nuts are naturally gluten free.
  • Steamed jasmine riceThe plainest order on the menu. Rice is naturally gluten free, and a bowl of it needs no sauce.
  • Larb moo (minced pork salad)A salad of minced pork and liver with a lime and fish sauce dressing, mint, onion, chili and toasted rice. Ask whether the dressing has anything beyond lime and fish sauce.
Ask first
  • The pad thai sauceRecipes differ: one bottled pad thai sauce is labeled gluten free, while another is made with soy sauce containing wheat. Ask what is in the one they use.
  • TofuPlain tofu is naturally gluten free, but ask whether it was marinated in soy sauce or battered before frying.
  • Shrimp or chickenPlain shrimp and chicken are naturally gluten free. Ask whether either was marinated, since marinades may contain soy sauce or flour.
  • Vegan or vegetarian pad thaiOne vegan pad thai sauce swaps the fish sauce for miso, but its label also lists soy sauce brewed with wheat. Ask what the kitchen uses in place of fish sauce.
Usually skip
  • Egg noodle versionsIf the menu lets you choose the noodle, keep the rice noodles: egg noodles typically contain gluten.
  • Pad see ewWide rice noodles fried with pork and Chinese broccoli, then flavored with dark soy sauce; soy sauce usually brings gluten with it.

Where gluten hides in pad thai

  • Soy sauce in the sauce
  • Bottled sauces
  • Marinades and batter
  • The noodles
  • The wok

Soy sauce in the sauce. Tamarind and fish sauce give pad thai its tart, salty base, and both are naturally gluten free. One vegan pad thai sauce swaps the fish sauce for miso, yet its label also lists soy sauce brewed with wheat. A wheat-free tamari avoids that, if the kitchen keeps one.1,2,3,5

Bottled sauces. Ready-made pad thai sauces are not all alike. One is labeled gluten free and lists tamarind, fish sauce, rice vinegar and preserved radish; another declares wheat on its label. If the kitchen pours from a bottle, ask to check the label.4,5

Marinades and batter. Chicken, shrimp and tofu start out gluten free, but marinades may contain soy sauce or flour. Fried tofu may also be battered, possibly with wheat flour, and frying it in oil shared with gluten-containing food makes cross-contact more likely.1,2,7

The noodles. Pad thai is a rice noodle dish, and one brand's stir-fry rice noodles list only rice and water. Rice noodles are almost always gluten free, while egg noodles typically contain gluten, so confirm which noodle goes into the wok.1,2,3,6

The wok. Pad thai is stir-fried, with the egg scrambled straight into the noodles, so everything shares one pan. Gluten can pass on through shared utensils and cookware, and for celiac disease the food must not come into contact with it, so ask whether the wok can be washed before your pad thai goes in.2,3

What to ask the waiter

  1. Do you make the pad thai sauce here, or pour it from a bottle?
  2. Does the sauce, or its label, list soy sauce or wheat?
  3. Was the tofu or chicken marinated or battered first, and in what?
  4. Which noodles go into your pad thai, and do they contain wheat?
  5. Can the wok be washed before my pad thai goes in?

With celiac disease, pad thai is worth ordering only when someone can name what is in the sauce and any marinade, and the kitchen can wash the wok before your pad thai goes in. If any answer is uncertain, choose another dish.

Questions people ask

Do pad thai noodles have flour?

Usually not wheat flour. Pad thai is made with rice noodles, and one brand's stir-fry rice noodles list only rice and water. Rice noodles are almost always gluten free, but ask the restaurant to confirm which noodles it uses, since egg noodles typically contain gluten.

What is in pad thai sauce?

Tamarind gives it a tart note and fish sauce a salty one, and both are naturally gluten free. Bottled versions differ: one labeled gluten free lists tamarind, fish sauce, rice vinegar and preserved radish, while a vegan one lists soy sauce made with wheat. Ask whether the kitchen makes its own sauce or uses a bottle, and what that bottle lists.

Is vegan pad thai gluten free?

It depends on what replaces the fish sauce. One vegan pad thai sauce uses miso as its salty base, and its label also lists soy sauce brewed with wheat. Ask what the kitchen uses instead of fish sauce, and whether a wheat-free tamari is on hand.

What should I ask about pad thai if I have celiac disease?

Ask about every part that could carry gluten: the sauce, any marinade, the noodles and any batter on the tofu. Then ask about the wok and the frying oil, because with celiac disease the food must not come into contact with gluten. This is general information, not medical advice; the kitchen has the final word.
