Ingredients
- 8 oz Korean sweet potato glass noodles
- 1 carrot, julienned
- 1 red bell pepper, julienned
- 4 oz spinach, blanched
- 4 oz mushrooms, sliced
- 3 tbsp soy sauce (or tamari)
- 2 tbsp brown sugar
- 1 tbsp sesame oil
- 2 cloves garlic, sesame seeds, green onion
How to Make Sweet Soy Noodles
1. Prepare the noodles
Place the glass noodles in hot water and soak for 10 minutes, or until pliable. Drain them thoroughly. Do not leave them sitting in water after they are flexible, because excess water can make the finished dish less glossy.
2. Prepare the vegetables
Julienne the carrot and red bell pepper into thin strips. Slice the mushrooms. Blanch the spinach briefly, then drain it well and squeeze out excess water. Cooking the vegetables separately helps each one keep its color and texture.
3. Make the sauce
In a small bowl, whisk together the soy sauce or tamari, brown sugar, sesame oil, and garlic. Whisk until the sugar is distributed through the sauce. Set it aside so it is ready when the noodles hit the wok.
4. Stir-fry the vegetables
Heat a wok or large skillet over medium-high heat. Stir-fry the carrots, peppers, and mushrooms separately or in batches until they are cooked but still have some bite. Move each cooked vegetable to a large bowl.
5. Sauce the noodles
Add the drained noodles to the hot wok. Pour in the sauce and toss continuously until the noodles are glossy and evenly coated. If they seem sticky, keep tossing rather than adding a large amount of liquid.
6. Finish the dish
Fold in the cooked vegetables and blanched spinach. Toss gently until everything is warmed through. Finish with sesame seeds and sliced green onion and serve.
Substitutions
- Gluten-free: use tamari instead of soy sauce.
- Vegetarian: this recipe is already vegetable-forward. Add extra mushrooms if you want more savory depth.
- For a different vegetable mix: keep the total volume similar and choose vegetables that cook quickly.
Tips & Troubleshooting
- Noodles are gummy: They were likely soaked too long or left wet after draining. Drain promptly and toss them in the sauce.
- Vegetables are soggy: Cook them over sufficiently high heat and avoid crowding the wok.
- Dish tastes too salty: Add more plain cooked vegetables or noodles rather than pouring in more soy sauce.
- Sauce is not glossy: Toss the noodles while the wok is hot so the sauce coats them evenly.
- Spinach made the dish watery: Squeeze it very well after blanching.
Storage & Reheating
Refrigerate leftovers for up to 3 days. Reheat in a hot skillet with a small splash of water, tossing until warmed through. Glass noodles are best fresh because freezing can noticeably change their texture.
Frequently Asked Questions
Can I prep this ahead?
Yes. Slice the vegetables and whisk the sauce ahead of time. Store the components separately in the refrigerator and cook the noodles when you are ready to assemble dinner.
Do I need a wok?
No. A large skillet works well. A wok simply gives you more room for tossing and high-heat cooking.
Can I add protein?
Yes. Cooked chicken, beef, tofu, or another protein can be added with the vegetables. Keep the original noodle and sauce proportions intact if you are making a small addition.
