The key to making Sukju Namul (Korean seasoned mung bean sprouts) is blanching 500 g (17.6 oz) of mung bean sprouts in boiling water with 2 tbsp vinegar for exactly 30 seconds, then cooling them quickly. This short blanching time helps preserve their fresh, crisp texture without letting the stems turn soft.
Once drained, the sprouts are gently tossed with 1/2 tbsp seasoned salt, 2/3 tbsp minced garlic, 1 1/2 tbsp sesame oil, and 1 tbsp sesame seeds. Green onion, carrot, and red chili pepper add extra color and texture, while the entire dish comes together in about 10 minutes.
The crisp, mild mung bean sprouts pair naturally with garlic and nutty sesame oil, making this easy Sukju Namul recipe a simple Korean vegetable side dish for everyday meals.

- 1/2 red chili pepper (10 g / 0.35 oz)

✓ How to Make Sukju Namul
- Slice the vegetables: Thinly slice 20 g (0.7 oz) of the green part of a large green onion, 20 g (0.7 oz) carrot, and 1/2 red chili pepper (10 g / 0.35 oz).
- Blanch the mung bean sprouts: Bring a large pot of water to a full boil. Add 2 tbsp vinegar and 500 g (17.6 oz) mung bean sprouts, then blanch for exactly 30 seconds. The vinegar helps the sprouts stay crisp.
- Rinse in cold water and drain: Immediately remove the blanched mung bean sprouts and rinse them briefly under cold water. Transfer to a colander and drain thoroughly.
- Season and toss: Place the drained mung bean sprouts, green onion, carrot, and red chili pepper in a bowl. Add 1/2 tbsp seasoned salt, 2/3 tbsp minced garlic, 1 1/2 tbsp sesame oil, and 1 tbsp sesame seeds. Gently lift and toss everything together with your fingertips until evenly seasoned.
✓ Key Tips for Success
- Keep the blanching time to exactly 30 seconds: Mung bean sprouts soften quickly when exposed to heat. Blanching them in boiling water for only 30 seconds helps keep the stems firm and preserves their signature crisp texture.
✓ Serving Tips
- Serve Sukju Namul as a topping for bibimbap or alongside spicy dishes such as Jeyuk Bokkeum (spicy stir-fried pork) or Dakgalbi (spicy stir-fried chicken). Its mild flavor pairs especially well with spicy foods.
- If you don’t have a red chili pepper, you can leave it out or substitute thinly sliced red bell pepper for extra color.
- The nutty aroma of sesame oil and the crisp bite of the mung bean sprouts are at their best right after seasoning. For the best texture, toss the sprouts with the seasonings shortly before serving.
✓ How to Choose Fresh Mung Bean Sprouts
- Stems: Look for sprouts with thick, plump stems that feel firm and springy.
- Color: Choose sprouts that are clear white overall, without brown or black discoloration around the roots.
- Moisture: Packaged mung bean sprouts should look fresh and firm rather than soft or soggy, with no excessive moisture inside the package.
