Pad Thai has become one of Thailand's what?

Pad Thai has become one of Thailand’s national dishes. Its status reflects both its popularity and its powerful association with Thai identity at home and abroad.

Although the dish is now treated as a signature of Thailand, its history is more recent and layered than many people assume. Stir-fried rice noodles have connections to Chinese culinary traditions, while the modern dish developed in Thailand during the mid-20th century and became especially prominent through street-food culture and national food policy.

Calling Pad Thai a national dish does not mean every Thai person eats the same version. Recipes differ by vendor and region, with variations in sweetness, sourness, protein, noodle texture, and garnishes. That flexibility helped the dish travel successfully internationally while remaining recognizably Thai.
