What is Pad Woon Sen?

The word “pad” in Thai means stir fry and “woon sen” means glass noodles. However, there are many delicious ingredients apart from noodles in it. It is a popular, quick stir-fried dish with vegetables like carrots and cabbage, scrambled eggs as well as protein like beef, chicken, shrimp, or pork. Vegetarian versions usually keep the eggs but add oyster mushrooms, shiitake mushrooms, or tofu instead of meat. Read more about it here.

What will it taste like? If you decide to make this vegan Pad Woon Sen recipe you’ll have a sweet and salty but rich and aromatic sauce loaded with shredded vegetables like carrots, cabbage, oyster mushrooms, mung bean sprouts, and tofu scramble. It is served with silky smooth glass noodles which are perfect to accompany the crunchy texture of the veggies.

Pad Woon Sen vs Pad Thai vs Pad See Ew

You may be more familiar with Pad Thai than this dish. While there are many variations that exist for all these dishes the main difference is the noodles. While Pad Woon Sen is prepared with mung bean noodles aka vermicelli or cellophane noodles, Pad Thai is served with flat rice noodles, and Pad See Ew is garnished with quite broad rice noodles.

The other difference is the sauce. For Pad Woon Sen you need soy sauce, oyster sauce, fish sauce, sugar, and water. As for Pad Thai, the sauce contains tamarind concentrate, soy sauce, fish sauce, palm sugar, and lime juice. And peanuts are a must topping as well. Pad See Ew literally means “fried soy sauce”, which is more or less the only ingredient you need.

You can read more about the other subtle differences between them in this article.

Ingredients

This Thai noodle dish has many variations depending on which vegetables and which type of proteins are added.

I think it turned out absolutely delicious. And if you try it, you’ll agree with me too. So what do you need?

glass noodles (thin mung beans noodles)
carrots
cabbage
marinated oyster mushrooms (but any of these 7 types) -> we used this recipe from our blog
onion
tomato
garlic
green onion
tofu scramble -> we used this recipe from Nora Cooks
soy sauce -> if you need to eat gluten-free, please choose one of these gluten-free soy sauce substitutes
hoisin sauce -> is the perfect vegan substitute for the oyster sauce as both are thick sauces with a complex umami flavor this recipe needs
sugar -> any really, but if you need it to be vegan, please don’t use honey and choose from these honey substitutes

How to make Pad Woon Sen vegan?

Preparing the ingredients

Peel and slice the onion.
Peel and mince garlic. Don’t use a grater as it will burn easily.
Wash and slice green onion.
Discard the outer leaves of the cabbage and cut the head into quarters. Cut one quarter into thin slices. If you need step photos of how to do it, check out our vegan coleslaw recipe.
Wash, peel, and cut carrots into thin matchsticks. If you need step photos of how to do it, check out our sauteed julienne carrots recipe.
Wash and slice tomato. Discard the seeds.
Cook or soak glass noodles according to package instructions. Drain water when they are ready.
Prepare tofu scramble or another vegan egg substitute separately. The original dish also uses beaten eggs which are added directly after the stir-fried veggies are moved to the side of the pan. But to make a vegan version, it is easier and less of a hassle if you prepare it separately.

Preparing the marinated mushrooms

Cut the stem of the oyster mushrooms and tear the cap into small shreds with our hands. If the stem is soft enough you can shred them as well. Basically, you only need these 3 steps to prepare oyster mushrooms before baking.
Mix together the marinade by adding these ingredients in a small bowl: soy sauce (or tamari), onion powder, garlic powder, black pepper, vegetable oil, balsamic vinegar, sweet smoked paprika powder, salt, and Worcestershire sauce.
Take a large bowl and cover the mushroom shreds with the marinade.
You can either bake them in the oven at 425 Fahrenheit (220 degrees Celsius) for 20 minutes or pan-fry them like in the below pictures.

Let’s make Thai glass noodle stir fry!

Take a wok, a frying pan, or a cast-iron skillet and heat it over medium-high heat.
Add vegetable oil and minced garlic. Stir and fry them for a minute. Make sure not too long as they can get easily burnt especially if you minced them too finely.
Add sliced onion, cabbage, and carrots. Fry them for approx. 6-7 minutes. Do not over-cook them, it is better if they remain a bit crunchy. (photo #1)
Add baked/pan-fried mushrooms and pre-cooked tofu scramble. Stir and fry for 1-2 minutes. This is just to re-heat all ingredients and mix them well with the vegetables. (photo #2)
Add pre-cooked noodles, hoisin sauce, soy sauce (or tamari), and sugar. Stir and fry for another 1-2 minutes. (photo #3)
Finally, add sprouts and green onion. Stir well. (photo #4)

FAQs and substitutions

Is Pad Woon Sen gluten-free?

Glass noodles are typically made of mung beans or rice, which should be gluten-free. To be on the safe side and to avoid cross-contamination choose certified products. Read our article on which noodles are gluten-free.

Soy sauce is sadly not gluten-free, so you need to use tamari, liquid aminos, or other gluten-free substitutes.

Albeit Hoisin sauce is dark, it is not made of soy sauce, but fermented soybeans and spices. It is supposed to be gluten-free.

The marinade we used for the oyster mushrooms can be easily made gluten-free if you follow the recommendations in the recipe card and choose gluten-free Worcestershire sauce and gluten-free balsamic vinegar.

How do you store it?

You can keep it in the fridge for 3-4 days tops without any problem.

Can you make them ahead of time?

You can store oyster mushrooms easily for up to a week in the fridge, or at room temperature for 1-2 days. The finished dish can be stored in the fridge for up to 3-4 days. When you are ready to serve them, reheat them in a microwave or in a pan.

What can you use instead of oyster mushrooms?

You can use any of these oyster mushroom substitutes. The closest ones are probably shiitake mushrooms and maitake mushrooms.
