Easy Korean Radish Side Dish (Mu Namul Recipe) with Perilla Seeds
Korean Radish Side Dish, also known as Mu Namul, is the perfect low-calorie, healthy banchan for anyone looking for a light yet satisfying meal without sacrificing flavor. This comforting stir-fry highlights the natural sweetness of the radish, and by adding perilla seeds, we create a rich, nutty flavor profile that is incredibly satisfying. This specific recipe uses a hint of tuna fish sauce to provide an authentic umami depth to the Korean radish with perilla seeds, making it a delicious Mu Namul recipe that is as nutritious as it is tasty.

What is Korean Radish Side Dish with Perilla Seeds?
In Korea, there are many side dishes made using radish. As a representative among them, this dish is made by thinly julienning the radish and stir-frying it with perilla oil and perilla seed powder. The addition of perilla oil adds savoriness and softness, and the unique flavor of perilla seeds blends with the sweet radish, making it highly popular as a home-cooked side dish. You can also mix this into the Bibimbap that you know so well. In Korea, radish becomes sweeter in autumn and winter, making this Korean radish side dish most delicious during those seasons, but it is a common home-style Banchan enjoyed frequently in other seasons as well.

Why you’ll love this Mu Namul

A Low-Calorie, Healthy Side Dish
Are you on a diet for your health? If you were looking for a Korean side dish that you can eat healthily while wanting to lose weight, this stir-fried Mu Namul recipe is perfect. Radish is fundamentally low in calories. Furthermore, this stir-fry does not use chili powder or strong seasonings, making it a pure-tasting side dish that is not irritating.
Radish is rich in dietary fiber and moisture, so it is good for gut health and is a healthy ingredient often called a “natural digestive.” I recommend this Korean radish side dish to you as one of the healthiest side dishes, featuring perilla seeds which are good for vascular health and reducing inflammation.

Ingredients You’ll Need
To make this authentic Korean radish side dish, gather these simple ingredients:

Substitutions
- What if I can’t find Korean Radish? The thick and sweet Korean radish might be hard to find if you are in Europe or the US. In that case, you can substitute it with Daikon (Japanese radish) found in Asian markets.
- What if I don’t have Perilla Oil and Perilla Seeds? Radish pairs best with the scent of perilla, so I recommend adding perilla oil and perilla seeds. The oil from the perilla seeds adds savoriness and softness, catching the bitterness of the radish and elevating the flavor. However, if you don’t have them, use sesame oil and toasted sesame seeds—though it will become a completely different dish.
- Make it Vegan You can omit the tuna fish sauce and add the Korean seasoning Yondu. But if that is hard to find, you can add a tiny bit more salt. However, since the umami will decrease significantly, I strongly recommend adding a very small amount of MSG. The deep flavor provided by that umami will make a huge, huge difference.
Step-by-Step Instructions
- Prep the Veggies: Julienne the Korean radish into thin, uniform strips. Thinly slice the green onion (song-song) and keep it ready for the final touch.

- The 10-Minute Marination: In a bowl, toss the julienned radish with 2 pinches of salt and 1/2 tsp of tuna fish sauce. Let it sit for 10 minutes. This step allows the seasoning to penetrate deep into the radish fibers of this Mu Namul recipe.

- Start the Stir-fry: Transfer the marinated radish (including any juices) into a pan over medium heat. Begin to stir-fry gently until the radish starts to look slightly translucent.

- Steam for Tenderness: When the radish starts to soften, add 50ml of water. Cover the pan with a lid, turn the heat down to low, and let it steam for 5 minutes. This makes the Korean radish side dish perfectly tender and “soft”, which is the hallmark of great Mu Namul.

- The Nutty Finish: Once the radish is fully cooked, add 1.3 tbsp of perilla seed powder, 1 tbsp of perilla oil, the sliced green onions and minced garlic. Stir-fry for another minute so the Korean radish with perilla seeds is well-coated in the creamy perilla sauce.

- Season to Taste: Give it a final taste. If you need a bit more salt, add 1-2 extra pinches. Sprinkle a pinch of toasted sesame seeds on top, and your healthy Mu Namul recipe is ready!

Expert Tips for the Best Results
Marinating the Radish: By marinating the radish, you draw out moisture to prevent it from breaking, making the texture delicious. You can also add seasoning to the radish this way.
Add Tuna Fish Sauce: There is an umami flavor that only tuna fish sauce gives, which salt or soy sauce cannot produce. If you don’t have it, you can substitute it with anchovy fish sauce.

Cut the Radish with a Knife: Using a mandoline is convenient and good, but you can preserve a better texture of the radish when it is cut with a knife.
Cut the Radish into Consistent Thickness: If some radish strips are thin and others are thick, they won’t cook evenly, so some parts might become too mushy while others remain too hard. It’s better to cut them into a consistent thickness to cook evenly.
Steam with Water: Stir-fried radish should be cooked with a little water added to steam it so the radish becomes soft and well-cooked.
