Namul — Korean-Style Seasoned Vegetables (3-Color Recipe)
Namul (ナムル) is the Korean-style seasoned vegetable side dish that shows up constantly in Japanese homes too — especially as the colorful topping for bibimbap. This is the three-color version I make: komatsuna (Japanese mustard spinach), carrot, and bean sprouts, each blanched and tossed in a simple sesame-and-garlic seasoning. It’s bright, healthy, keeps well, and it’s the kind of thing we make a big bowl of and eat all week.
I based mine on a hugely popular Japanese home recipe and seasoned it with what’s in our Kyushu kitchen — Fundokin soy sauce, sesame oil, a little chicken stock powder for umami, and plenty of toasted sesame. It comes together in about fifteen minutes, and I used this exact batch to make a bibimbap rice bowl.

What is Namul?
Namul is a Korean term for seasoned vegetables — usually blanched or lightly cooked, then dressed with sesame oil, garlic, salt, and sesame seeds. It’s one of the most common banchan (side dishes), and a set of colorful namul is what makes bibimbap look and taste so good. In Japan it’s become a familiar home dish in its own right, often with a pinch of chicken stock powder added for extra umami, the way I make it here. If you like this kind of quick vegetable side, try my green pepper and chikuwa namul too.
Ingredients (Serves 3–4)
| Ingredient | Amount | Notes |
|---|---|---|
| Komatsuna (or spinach) | 1 bunch | Cut into 4–5cm lengths |
| Carrot | 1/2 | Cut into thin matchsticks |
| Bean sprouts (moyashi) | 1/2 bag | About 100g |
| Sesame oil | 1 tbsp | Toasted |
| Soy sauce | 1 tsp | |
| Chicken stock powder | 1 tsp | For umami |
| Salt | A pinch | To taste |
| Toasted sesame seeds | 1 tbsp | Plus more to finish |
| Garlic (optional) | A little grated | For a more Korean flavor |
The flavor really comes from good toasted sesame oil and a generous amount of toasted sesame seeds — don’t be shy with either. A pinch of chicken stock powder is my little umami shortcut, very common in Japanese home namul.
How to Make Namul
Step 1: Prep the Vegetables
Cut the komatsuna into 4–5cm lengths, slice the carrot into thin matchsticks, and rinse the bean sprouts. Cutting everything to a similar size helps it cook evenly and look tidy in the finished dish.
Step 2: Blanch the Vegetables
Bring a pot of water to a boil. Add the carrot first (it takes longest), then the komatsuna stems, then the leaves and bean sprouts — or just blanch them in quick batches. You only need a minute or two; the vegetables should stay bright and slightly crisp, not soft.
Step 3: Cool and Squeeze Out the Water
Drain the vegetables and cool them in cold water, then — this part matters — squeeze out as much water as you can with your hands. Watery vegetables make watery, bland namul, so really wring them dry. This is the single biggest thing that separates good namul from soggy namul.
Step 4: Mix the Seasoning
In a bowl, combine the sesame oil, soy sauce, chicken stock powder, a pinch of salt, the toasted sesame seeds, and grated garlic if using. Stir it together into a quick dressing.
Step 5: Toss and Serve
Add the squeezed vegetables to the bowl and toss until everything is evenly coated. Taste and adjust with a little more salt or sesame oil. Finish with an extra sprinkle of sesame seeds. Serve at room temperature or chilled.
Tips and Variations
- Squeeze the vegetables well. The number one rule — dry vegetables mean flavorful namul.
- Season each vegetable separately if you want the classic restaurant look, or toss them all together for an easy home version like this one.
- Add garlic and a little gochugaru (Korean chili flakes) for a more Korean, spicier flavor.
- Use what you have. Spinach, soybean sprouts, zucchini, or shredded cabbage all make great namul.
What to Serve It With
- Piled onto rice as bibimbap — this namul is the perfect topping.
- As a side dish with grilled meat or fish and rice.
- In a bento box — it holds up beautifully.
Storing
Namul keeps well in a sealed container in the fridge for 3–4 days, which is part of why it’s such a popular make-ahead side. The flavor deepens as it sits. It’s best eaten cold or at room temperature straight from the fridge — no reheating needed. I wouldn’t freeze it, as the vegetables lose their texture.
Frequently Asked Questions
What vegetables can I use for namul?
Almost any. The classic three-color version uses a leafy green (spinach or komatsuna), carrot, and bean sprouts, but soybean sprouts, zucchini, cabbage, and mushrooms all work. Just blanch or lightly cook each one and squeeze out excess water before seasoning.
Is namul Korean or Japanese?
Namul is originally Korean — seasoned vegetable side dishes and the components of bibimbap. It’s also very popular in Japanese home cooking, often made with a pinch of chicken stock powder for umami, which is how I make this version.
How long does namul last?
Stored in a sealed container in the fridge, namul keeps for 3–4 days and the flavor only improves. That makes it ideal for meal prep and bento. Don’t freeze it, though, as the blanched vegetables turn watery when thawed.
