Most Thai cooking schools offer a vegetarian track if you mention it at booking — fish sauce is replaced with soy or vegetable broth, shrimp paste with miso or omitted.
Dedicated vegan schools: - Sammy's Organic Thai Cooking (Chiang Mai) — 100% vegetarian/vegan menu - May Kaidee Vegetarian Thai Cooking (Bangkok and Chiang Mai) — long-running pure vegan school - Pun Pun Center (Chiang Mai outskirts) — organic farm cooking with vegan focus
What to specify when booking: - Vegan vs. vegetarian (egg/dairy) - Severe allergies (peanut especially common in Thai dishes) - Spice tolerance
Most popular vegan-friendly dishes taught: Tom Kha Het (mushroom coconut soup), Pad See Ew (with tofu), Green Curry (with vegetables), Som Tam (papaya salad — easily made vegan).
Note: Standard "vegetarian" Thai food often includes fish sauce. Always say "jay" (เจ) to mean strict vegan, "mangsawirat" (มังสวิรัติ) for vegetarian-with-eggs/dairy.
