What is pad woon sen
It’s a Thai stir-fried glass noodle dish. Pad (ผัด) – means fried and Woon sen (วุ้นเส้น) – means vermicelli – a type of noodle made with mung beans, also known as bean thread noodles or cellophane noodles.
The glass noodles are stir-fried with a protein (chicken, pork, shrimp, or beef), vegetables, and eggs in a deeply savory and sweet sauce. Woon sen pad thai tastes smoky, sweet, and savory. It’s absolutely sensational.
Ingredients and low carb substitutes
- Noodles – kelp noodles (low carb) or regular cellophane glass noodles. See more info on kelp noodles below.
- Pad Woon Sen Sauce: coconut aminos, fish sauce, keto brown sugar (or coconut sugar), ketchup, and a thickener starch.
- Proteins: Chicken and/or shrimp, and eggs.
- Vegetables: Chinese broccoli (or broccolini), carrots, and onion.
Kelp noodles are made from edible kelp (kombu). They are super low in carbs because they are made without starch and grain flour. Kelp noodles are cholesterol, fat, and gluten-free, and also rich in nutrients. They are a good dietary source of iodine. (source). You can learn what are kelp noodles here.
How to use kelp noodles
Kelp noodles have a crunchy and rubbery texture. To soften the noodles, soak and massage the noodles in lemon juice mixed with baking soda. The noodles turn soft within 1 minute. Rinse them under cold water and the noodles are ready to eat. No cooking is required. Learn more about how to cook kelp noodles. You can see how I add these noodles to my winter melon soup with meatballs.

What’s the difference between pad woon sen and pad thai?
The types of noodles used are different between Thai pad woon sen and pad thai. Woon sen uses glass vermicelli noodles that are semi-transparent and made from mung beans. Pad Thai uses rice noodles. Pad Thai also tastes nutty (because of the usage of peanuts) than Pad Woon Sen (sweet, savory, and a little tangy).
What noodles to use for Thai pad woon sen?

Final Tips and Summary
- Noodles: You can use the same recipe, using kelp noodles (low carb) or regular bean thread noodles.
- Cookware: Stir-fry with a 12-inch large saute pan as you need the space to hold all the ingredients.
- Temperature: Keep your saute pan hot during the whole time of cooking.
- Timing: Keep cooking time short and fast.
- Ingredients: Select vegetables that don’t contain much moisture and liquid as they might dilute the sauce.
- Not soaky: Pad woon sen is not a saucy dish. Regular bean thread noodles will thicken and soak up the sauce (thus they keep the dish not soaky). Kelp noodles react the complete opposite as they do not contain starch. Therefore your pan temperature, cook time, and ingredient selections are extra important.
Pad Woon Sen (Thai stir-fried glass noodles)
For the kelp noodles:
- 12 oz. kelp noodles, 1 packet
- 1/4 cup lemon juice
- 2 tsp baking soda
- 0.75 lb Chicken thighs, skinless and boneless, dice to bite sizes
- 8 pieces Large shrimp, peeled and deveined, optional
- ¼ tsp garlic powder
- ½ tsp coarse sea salt
- ⅛ tsp ground black pepper
- 2 tsp toasted sesame oil
- 2 large eggs
- 2 oz. yellow onion, sliced, about half of 1 medium
- 0.8 oz. clove garlic, finely minced, about 4 cloves
- 2 oz. carrots, diced on diagonal, about 1 medium
- 9 oz. Chinese broccoli, or broccolini, slice the stems on diagonal at a 45° degree angle bias cut
- 2 bulb scallions, diced to 2-inch sections
- 3 tbsp avocado oil, divided
- sprinkle coarse sea salt
- sprinkle ground black pepper
- 2 tbsp coconut aminos
- 1 tbsp fish sauce
- 1.5 tsp keto brown sugar, or coconut sugar
- 1 tsp ketchup
- 1/4 tsp xanthan gum, or 1 tsp arrowroot or tapioca starch
Prepare the kelp noodles:
- Take the noodles out of the packet and discard the water. In a large bowl, mix the lemon juice with baking soda with a spoon. You’ll see bubbles immediately. Immediately add the noodles to the bowl, and massage them for about 1 minute. The noodles will soften. Transfer the noodles to a colander rinse under running water for 1 minute. Set aside to drain well. The noodles are ready to eat.
Prepare the ingredients:
- Prepare the chicken in a bowl with garlic, salt, pepper, and sesame oil. Set aside the onion, garlic, carrots, Chinese broccoli, and scallions on a large plate in separate piles. Mix the sauce in a small bowl,
Cook the chicken and/or shrimp:
- Chicken: Preheat a large saute pan, ideally 12-inch wide, over medium heat until the pan is hot. Add 1.5 tbsp oil. Pan sear the chicken over medium-high heat until almost cooked through, about 3 minutes. Push the chicken to the side of the pan and crack two eggs and add them to the center. Break the eggs with a spatula as if you are making scrambled eggs. Cook for another 2 minutes. Transfer them out to a plate.
- If you select shrimp, you don’t need to season it. Pan sear them over medium heat for about 2-3 minutes per side and transfer them out to a plate.
- Using the same pan and keep your pan hot by preheating it for a few seconds over medium heat. Add 1.5 tbsp oil, quickly saute the garlic, carrots, and onion with a pinch of salt for 10 seconds, stir-often. Turn the heat up to medium-high, add broccoli and scallions, saute for 20 seconds. Return the chicken and eggs, kelp noodles, and the sauce to the pan. Toss for about 10 seconds. Turn off the heat and transfer them to a large serving plate. Sprinkle it with black pepper and serve warm.
- Bias cut is a crosswise cut at a 45° angle; most often used in cutting vegetables, particularly on thick vegetable stems, for Asian dishes. The stems cook faster in stir-fries under high heat so that the vegetable remains crisp and tender.
- About kelp noodles – The taste and flavor of kelp noodles are very similar to Chinese bean thread noodles (glass noodles) but super low in carb. They are rubbery when you open the packet but after you give them a quick lemon juice + baking soda massage bath, the noodles turn soft and are ready to eat.
- The kelp noodles continue to turn softer if they are soaked in water. Please do not soak them in liquid for more than 1 minute. They might clump slightly as they dry out but as soon as they are in contact with liquid, they will bounce back.
- Because kelp noodles contain little to no starch, they don’t absorb the liquid in the pan and therefore the dish tends to turn watery. To compensate its nature, you should 1) keep your pan hot the whole time, 2) select ingredients that don’t produce more liquid, 3) keep the cook time fast and short, and 4) add a little starch (xanthan gum for keto, tapioca arrowroot starch for paleo), to thicken the pan juice. Avoid extra liquid as it dilutes the sauce and flavor.
- If using regular bean thread noodles – They come in dry forms. Do this while you prep the dish – Soak 1-2 bundles of bean thread noodles in a large bowl of room-temperature water for about 10 minutes. Drain the noodles using a strainer and make two cuts with kitchen shears. Toss the noodles with olive oil or toasted sesame oil so they are less likely to clump. If they become clumpy, they will bounce back as soon as they are in contact with the sauce and the liquid in the pan. Bean thread noodles also release starch and soak up the sauce so you can skip the starch element in my recipe card and increase the sauce quantity volume, if needed.

The Kelp noodles are SO tasty! And the sauce flavors are wonderful. One direction that confused me: I found 3ish minutes wasn’t enough for the chicken to cook through. I ended up having to keep it in longer after the veggies step. Any tips to avoid that next time? Thank you! Love your recipes.
Thank you. You need to get your pan hot. Use a 12-inch size large skillet for the same recipe quantity of chicken. 🙂
If you want to treat yourself to take our flavors, this is the recipe for you! It is delicious and impossible to tell that it is low carb!!!!!
Thank you, Mariah. So sweet of you!
This is the first I’ve heard of kelp noodles. In my very rural area, it’s not an ingredient I have available locally. Are you familiar with konjak noodles? Would the lemon & baking soda bath have simiyresults in making the konjak noodles softer/less rubbery? Thanks for the inspiration!
I have many konjac noodles (AKA miracle noodles or shirataki noodles) recipes on my site. Please feel free to check them out. Just type “shirataki”. Haven’t tried the lemon bath with them yet. 🙂
So easy and healthy! I was so excited to try these kelp noodles and were amazing. Thank you!
Wow, this dish takes me back to Thai restaurants before my celiac diagnosis. Bowl of delicious comfort! I’ve never had success with kelp noodles, and they had just the right texture this time. Thank you for this awesomeness!
That’s awesome. I’m so happy to hear!
This recipe is FANTASTIC! I did make a few tiny alterations but no issue at all…it was devoured. I am allergic to eggs.so left those out and I ran out of Coconut Aminos so I sub’d Tamari. Lastly, I did add a good amount of crushed red pepper because we are spice addicts.
As always, her recipes are just WONDERFUL in my experience, thank you so much!!!!
These look great! Can you substitute apple cider or rice vinegar for the lemon juice? Thanks1
Yes you can but the noodles might have a slight vinegar flavor.
This dish looks so amazing! I love Thai food and am trying to cut down on carbs – this is perfect!! A delicious and complete meal with so much flavor!
I’ve been wanting to try kelp noodles for so long and this was the perfect excuse! I loved this dish!
Loved this recipe! It was surprisingly filling and came together really quick. I used what I had on hand; I used just shrimp and subbed spinach for broccoli. The sauce really brings the flavor together. Can’t wait to use kelp noodles more!
This looks delicious! Some eaters in my household don’t like seafood. Do you think it would still be okay if I leave out the shrimp?
Yes. Use either chicken OR shrimp. OR a combination.
My first time trying kelp noodles and not only were they delicious but the stir fry was so deliciously flavored!
Thank you for letting us know how to use these kelp noodles. I always thought they are crunchy and didn’t like the texture. But the lemon juice and baking soda seriously made a difference! I sauteed some vegetables with chicken and the noodles, the sauce is amazing – sweet and savory. I’ll be using this low carb noodle more often now. Thanks again!
That’s awesome. I’m so happy to hear!
