Thai Prawn Glass Noodles

Posted on April 30, 2021December 30, 2025 By Alexandra Wong 4 Comments on Thai Prawn Glass Noodles
Jump to Recipe Print Recipe

I first ate iconic Thai dish goong ob woonsen (prawn glass noodles) 20 years ago at a restaurant in Thailand, while travelling with my mum and aunt. So long ago, yet I can still remember the taste like yesterday. The combination of juicy fresh prawns and saucy noodles in a spicy and fragrant peppery paste left me in awe.

Something so otherworldly delicious must be very difficult to make, my distinctly un-cheffy twentysomething mind thought.

It never crossed my mind that I’d be making prawn glass noodles myself, until I came across a recipe by @hotthaikitchen. As I read through the instructions, I thought, eh, it doesn’t sound that difficult.

Well, I’ve made Thai prawn glass noodles a few times now and we LOVE IT.

What makes this dish a winner is it’s amazingly easy to make and requires only a few ingredients!

 

* The freshest prawns because they contribute a natural brininess to the dish that frozen ones lack. And nope, you don’t even have to marinate the prawns in anything.
* Garlic, black pepper and coriander to make up saam kler (“three buddies”). This aromatic paste features prominently in many Thai dishes
* Seasoning sauce such as oyster sauce, light and dark soya sauce, salt and sugar.

While this is a very forgiving recipe, there are one or two things that could potentially affect the results, especially if you are not a very experienced cook.

Watch out for the following

  • During the last stage of the cooking, you cover the prawns with a lid and cook on low heat until prawns are done. The timing will vary depending on the type of cookware you use and the temperature of your kitchen stove. If you cook too long and your flame is too high, you will end up with a dry noodles i.e. not enough sauce. Make sure you cook on the lowest heat possible. If you’re not sure, open the lid and take a peek. Add more broth if necessary. 
  • Season according to your preference. For seasoning, I only use oyster sauce – and a minimal amount at that.  As I’m trying to go towards a more low-sodium and low-sugar direction, I have tweaked the recipe to suit my own health requirements. My version might be too subtle for your tastebuds. Most prawn glass noodles recipes will call for additional soy sauce, sugar and fish sauce, but these sauces already contain lots of salt and sugar. To avoid compromising on the taste, I rely on the naturally briny prawns and punchy coriander, garlic and black pepper paste.

Does it make any difference?

The aromatic sauce brings out the natural sweetness of the fresh fresh prawns

Honestly, hubs and I actually prefer my more minimalistic version. The lighter seasoning allows the freshness and sweetness of the prawns to really stand out. If you decide to go with my version and find the seasoning lacking, you can always add in the other sauces at the end.

This is such a quick, satisfying meal – exactly what we need during these trying COVID19 times! Trust me when I say this hearty dish can be assembled in minutes, then devoured even quicker with no leftovers.

Happy eating! 🙂

Notes

Thai Prawn Glass Noodles - Quick FAQ

1. What is Goong Ob Woonsen?

Goong Ob Woonsen is an iconic Thai dish consisting of succulent prawns and glass noodles (vermicelli) steamed in a pot with a fragrant, peppery sauce. The name literally translates to "prawns baked with glass noodles," and it is prized for its combination of juicy seafood and noodles that have fully absorbed the aromatic seasonings.

2. Is it hard to make Thai Prawn Glass Noodles at home?

No, Goong Ob Woonsen is surprisingly easy to make and can be assembled in minutes. Despite its "otherworldly" flavor, it requires only a few key ingredients and a simple steaming process, making it an ideal recipe for beginner cooks or quick weeknight meals.

3. What are the "Three Buddies" (Saam Kler) in Thai cooking?

In Thai cuisine, "Saam Kler" (the three buddies) refers to a foundational aromatic paste made from garlic, black pepper, and coriander (cilantro) roots or stems. This punchy trio provides the essential fragrance and depth of flavor for dishes like Goong Ob Woonsen.

4. Should I use fresh or frozen prawns for glass noodles?

For the best results, use the freshest prawns available. Fresh prawns contribute a natural sweetness and brininess to the noodles that frozen varieties often lack. Using high-quality fresh prawns also eliminates the need for a complex marinade.

5. Why are my Thai glass noodles dry?

If your glass noodles turn out dry, the heat may have been too high or the cooking time too long. To maintain a "saucy" consistency, cook the dish on the lowest heat possible and keep the lid tightly closed. You can take a quick peek during the last stage and add a splash of broth if the liquid has evaporated too quickly.

6. What kind of sauce is used for Goong Ob Woonsen?

The traditional seasoning sauce is a blend of oyster sauce, light soy sauce, dark soy sauce, salt, and sugar. However, for a healthier low-sodium version, you can focus primarily on oyster sauce and rely on the natural flavors of the prawns and the "three buddies" aromatic paste.

7. Do I need to marinate the prawns for this recipe?

No, you do not need to marinate the prawns. When cooked on top of the noodles in a covered pot, the prawns release their natural juices directly into the glass noodles, while simultaneously absorbing the flavors of the steaming aromatic sauce.

8. Can I make a low-sodium version of Thai prawn noodles?

Yes. To reduce sodium and sugar, you can use a minimal amount of oyster sauce and omit additional fish sauce or salt. Enhancing the recipe with extra garlic, black pepper, and coriander ensures the dish remains flavorful and "punchy" without excess salt.

9. How long do you cook prawns in glass noodles?

Prawns typically take 5 to 8 minutes to cook when placed in a single layer on top of the noodles under a closed lid. The exact timing depends on the size of the prawns and your specific cookware; they are done as soon as they turn opaque and pink.

10. What can I serve with Thai Prawn Glass Noodles?

Goong Ob Woonsen is a hearty, all-in-one meal that is satisfying on its own. Because it features both protein and carbohydrates (the noodles), it is often served as a main course, but it can also be part of a larger Thai family-style feast.

    I tried this recipe, so simple and easy to prepare. I didn’t use the dried shrimp and added some fish sauce because it reminds me of thai food! Also a dash of dark soya sauce to make it look darker. Our family loved it! Keep the practical recipes coming! I feel that i don’t need to be intimidated by recipes anymore.
