About this recipe
What Is Tianshui Mian?
Tianshui mian (甜水面), which literally translates to "sweet water noodles", is a classic noodle dish from Chengdu in China's Sichuan province.
Despite the name, there isn't actually any water involved in the sauce. Instead, the dish gets its signature flavour from a sweetened soy sauce combined with fragrant sesame paste, chilli oil, garlic water and ground Sichuan peppercorns.
The noodles themselves are just as important as the sauce.
Traditionally, they are thick, wide and delightfully chewy, giving them a satisfyingly bouncy texture that perfectly captures all those bold flavours.
A Beloved Street Food From Chengdu
Tianshui mian is one of Chengdu's most iconic snacks and can be found everywhere from humble noodle shops to bustling street food stalls.
Alongside dishes such as dan dan noodles, liangfen and wontons in chilli oil, it forms part of the city's incredibly rich and diverse noodle culture.
Sichuan cuisine is often associated with fiery heat, but what makes dishes like tianshui mian so special is the balance of flavours.
Here, sweetness, savouriness, nuttiness and spice come together in harmony, while the famous Sichuan peppercorns provide the distinctive málà sensation - a gentle numbing tingle that slowly builds with every bite.
Why You'll Love This Recipe
If you've ever travelled to Chengdu and found yourself dreaming about the food afterwards, this recipe is for you.
The sauce is surprisingly easy to make and uses ingredients that are readily available in most Asian supermarkets.
While you can absolutely take a shortcut and use frozen udon noodles, making the noodles from scratch gives them that extra chewy bite that makes tianshui mian so irresistible. They're probably the chunkiest noodles I've ever made, but trust me, they're worth the effort.
Best of all, this dish delivers everything I love about Sichuan food in one bowl: sweet, savoury, spicy and mouth-tingling flavours that somehow keep you going back for another bite.
It's no wonder this was one of the dishes I became completely obsessed with during my time in Chengdu.

Instructions
1. Make the Noodles
Mix the flour, water and salt together until a shaggy dough forms. Knead for 5 minutes until smooth, then cover and rest for 30 minutes.
Give the dough another quick knead before resting for a further 30 minutes.
2. Prepare the Sweetened Soy Sauce
Meanwhile, add the soy sauce, brown sugar, star anise, Chinese cinnamon and Sichuan peppercorns to a small saucepan.
Simmer gently for 10–15 minutes until slightly thickened and fragrant. Strain and leave to cool.
3. Shape and Cook the Noodles
Divide the dough into two and roll each piece into a rough rectangle. Cut into thick strips and gently stretch them before cooking.
Cook the noodles in boiling water for around 5 minutes, or until cooked through and wonderfully chewy. Drain and immediately rinse under cold water.
4. Assemble the Sauce
Combine the grated garlic and water to make a garlic water.
Add the garlic water, sweetened soy sauce, chilli oil, sesame paste and ground Sichuan peppercorns to a bowl and mix until smooth.
Toss through the noodles and serve immediately.
Top Tips
- Don't make the noodles too thin. Tianshui mian is famous for its chunky, chewy texture.
- Rinse the noodles in cold water after cooking to help them develop that springy bite.
- Adjust the chilli oil and Sichuan peppercorn to your liking depending on your spice tolerance.
- Short on time? Frozen udon noodles make an excellent shortcut.
FAQs
Can I use store-bought noodles?
Absolutely. Frozen udon noodles are a great substitute and are perfect if you're looking for a quicker weeknight version.
What does Tianshui Mian mean?
It translates to "sweet water noodles", referring to the sweetened soy sauce that gives the dish its distinctive flavour.
Is Tianshui Mian very spicy?
It can be! But the beauty of making it at home is that you can easily adjust both the chilli oil and Sichuan peppercorn to suit your own spice tolerance.
What is the difference between Tianshui Mian and Dan Dan Noodles?
Dan dan noodles are typically served with minced meat and a more savoury sauce, whereas tianshui mian is usually meat-free and has a distinctive sweet and spicy flavour profile with thick, chewy noodles.
Can I make the sweetened soy sauce in advance?
Yes! The sauce can be prepared several days ahead and stored in the fridge, making it even easier to throw together a bowl of noodles whenever the craving strikes.
