Thai cooking is built on plenty of vegetables, tofu, and fruit, but "looks vegetarian" and "is actually vegetarian" aren't the same thing, because many dishes are seasoned with fish sauce, shrimp paste, oyster sauce, or bone broth. Understanding the vocabulary and ordering correctly is the trick that lets you eat with peace of mind.
Jay vs vegetarian — what's the difference
| Word | What it means | Suits |
|---|---|---|
| Jay (เจ) | Strict vegan — no meat, egg, or dairy, and no pungent vegetables (garlic, onion). Look for the yellow flag with the เจ character. | Vegan |
| Mangsawirat (มังสวิรัติ) | Vegetarian — no meat, but may include egg or dairy. | Vegetarian |
| Plain vegetables (general) | Veggie dishes at ordinary restaurants; may still have fish sauce/shrimp paste added. | Order with extra instructions |
Ordering phrases that actually help
- "Kin jay" (I eat vegan/jay) — signals strict vegan (understood easily nationwide)
- "Mai sai neua sat" (no meat) — leave out the meat
- "Mai sai nam pla" (no fish sauce) — very important; many dishes get fish sauce even when they look like vegetables
- "Mai sai kapi / mai sai hoy nang rom" (no shrimp paste / no oyster sauce) — avoid animal-based seasonings
- "Mangsawirat, tan khai dai/mai dai" (vegetarian, with/without egg) — state your level clearly
Dishes that are easy to make plant-based
Many dishes can be adapted to plant-based, such as stir-fried mixed vegetables, pad kaprao with tofu/mushroom, vegetable fried rice, jay pad thai, jay som tam (no fermented fish or dried shrimp), green curry with tofu, and fresh fruit. Most made-to-order shops can cook a veggie version if you say so clearly. Restaurants with an "aahaan jay" or "mangsawirat" sign are the most worry-free to order from.
Easiest cities for restaurants, and the vegetarian festival
💡 Eating plant-based made easier
The most vegan- and vegetarian-friendly city, with lots of cafés and vegan restaurants.
Plenty of vegan/vegetarian restaurants, especially around Sukhumvit and Ari, plus jay food stalls at the markets.
During the 9-day festival, especially in Phuket, the whole town fills up with jay food — a paradise for vegans.
Shops flying a yellow flag or showing the เจ character serve strict vegan food, so you can order anything.
