What is Cold Soba Noodles with Perilla Oil Dressing
Cold soba noodles with perilla oil dressing (also known as perilla oil noodles) is a trendy Korean noodle dish. It is called Deulgireum Makguksu (들기름 막국수) in Korean, a type of Memil Guksu. Memil means buckwheat and guksu means noodles.
Boiled and drained soba noodles are dressed with a sauce made from perilla oil, soy sauce, toasted sesame seeds and other pantry staple items.
This sauce recipe for noodles is not spicy like the many types of Korean soba noodle dishes. That puts this dish in the Ganjang Bibim Guksu, 간장 비빔국수 (soy sauce mixed noodle) category.

You can even buy a pre-packaged version of perilla oil noodles as shown in the picture below. The package reads “Memil Makguksu (메밀 막국수)”. Although I found this to be less delicious than homemade ones.
What is Perilla Oil
Perilla oil is a type of vegetable oil extracted from the toasted seeds of a plant called perilla. Toasted perilla oil is nutty and earthy in smell and flavor, light brown in color; similar to toasted sesame oil. However the flavor profile is quite different to that. It is often used in Korean sautéed vegetable dishes.

Substitution Tips
- Soba Noodles – Soba noodles or buckwheat noodles will work best for this recipe, but if you can’t find them, you could substitute with somen noodles (somyeon 소면). Because they’re much thinner than soba noodles, the chewing texture may not be quite right, but they absorb flavors well.
- Perilla Oil – If you cannot find perilla oil, you could use sesame oil. While the taste profile is quite different, the nutty aroma and taste of sesame oil is more similar to perilla oil than other types of oil. If you’re using sesame oil, make sure to use toasted sesame oil, rather than un-toasted sesame oil, as it will give a nuttier flavor. Also, use less of it than the recipe calls for. For example, if the recipe says 2 Tbsp perilla oil, use 1 to 1.5 Tbsp sesame oil.
- Tsuyu – This is a multipurpose Japanese condiment that can be used as a dipping sauce or soup base for Japanese noodle soup. It is most commonly used as an accompaniment to soba and udon noodle dishes as well as tempura dishes. This condiment is also used in some Korean or Korean-Japanese fusion dishes as well. You could substitute tsuyu with homemade dried anchovy and kelp stock (Korean soup stock). Though, tsuyu tastes a bit stronger than Korean soup stock, so you will want to dilute it with some water to balance out the flavor.
How to Serve
As this dish is a cold noodle dish, you serve the noodles cold. You also won’t need to serve any side dishes with this soba noodles. However, if you want you can prepare extra toppings (as mentioned in the recipe below) to supplement the meal. I don’t normally bother with any extras as the whole point of this soba noodle is simplicity.
If you want to indulge more in Korean flavor and texture, you could serve with pickled radish or cucumber pickles.
You could serve with white kimchi too, but I wouldn’t recommend regular kimchi as it can overpower the taste.
