Pad Thai is stir-fried rice noodles in a sauce that balances the fruity sourness of tamarind, the saltiness of fish sauce and the sweetness of palm sugar. This is the tofu-and-egg version: the classic base, which you can easily turn into chicken or prawn Pad Thai.
What is Pad Thai?
Pad Thai (phat thai, “Thai-style stir-fry”) is one of Thailand’s best-known dishes: flat rice noodles stir-fried with a sauce of tamarind, fish sauce and palm sugar, with egg, tofu, bean sprouts and garlic chives, served with lime and roasted peanuts.
It was popularised in Thailand in the 1930s and 1940s and is now a street-food staple. In Bangkok you’ll often get it with prawns; at home, tofu, prawns or chicken all work well.
Which noodles for Pad Thai?
Use dried flat rice noodles about 3–5 mm wide. Don’t boil them: a soak in lukewarm water is enough, and the sauce and heat of the wok do the rest. Very thin rice vermicelli breaks up, and very wide ribbons are hard to fry evenly. Fresh rice noodles can be used too — skip the soaking and just loosen them before frying.
How to make Pad Thai sauce
For 2 portions you need about 100 ml of sauce: 45 ml tamarind purée, 30 ml fish sauce and 35 g palm sugar, warmed until the sugar dissolves. Shop-bought Pad Thai sauces are often much sweeter and thickened with starch.
If you have a block of tamarind, pour 150 ml hot water over 50 g, leave for 15 minutes, mash and push through a sieve. Tamarind concentrate in a jar is several times stronger — start with 1 tbsp diluted with water. Ketchup, oyster sauce and peanut butter don’t belong in the classic sauce.
Chicken or prawn Pad Thai
Chicken: use 250 g boneless chicken thighs or breast in thin 5 mm strips instead of the tofu. Stir-fry for 4–5 minutes until completely white inside (75 °C if you have a thermometer), lift out and return with the bean sprouts so it stays juicy.
Prawns: use 200 g raw peeled prawns. Fry for 1½–2 minutes until pink and opaque, lift out and return in the second-to-last step. Defrost frozen prawns in the fridge or in cold water and pat them very dry.
Vegetarian Pad Thai
Swap the fish sauce for light soy sauce or tamari (start with less — it’s often saltier; regular soy sauce contains gluten). Leave out the egg or replace it with extra tofu and the dish is vegan.
