KOREAN INGREDIENT GUIDE
Ganjang (Korean Soy Sauce)
Ganjang (Korean Soy Sauce) is one of the most essential ingredients in Korean cooking. Made by fermenting soybeans, it adds saltiness, rich umami, and depth to everything from marinades and stir-fries to soups and dipping sauces.
If you want to cook authentic Korean food at home, this is one ingredient you should always have in your pantry.
What Is Ganjang (Korean Soy Sauce)?
Ganjang is Korea’s traditional soy sauce, made by fermenting soybeans. Dark in color and rich in flavor, it is one of the most widely used seasonings in Korean kitchens.
Unlike many soy sauces that are mainly served as a table condiment, Korean soy sauce is used throughout the cooking process. It seasons ingredients, builds umami, and gives countless Korean dishes their signature depth of flavor.
What Does Ganjang Taste Like?
Ganjang is best known for its salty flavor, but there is much more to it than salt alone.
Fermentation creates a deep umami taste with subtle sweetness and a lightly roasted aroma. Rather than overpowering a dish, it enhances the natural flavor of the other ingredients.
How Is Ganjang Used?
Ganjang is used throughout Korean cooking, although some dishes that are intentionally kept very light or clear may be seasoned differently.
It is commonly used to season meat, vegetables, noodles, and side dishes, often together with salt to create a balanced flavor. It also plays an important role in marinades, braising sauces, and stir-fries.
In Korea, it is also served as a dipping sauce for foods such as Korean pancakes (jeon), dumplings, and fried dishes. Many people add a little vinegar or Korean chili flakes for extra flavor.
Popular Korean Dishes Made with Ganjang
Korean soy sauce is an essential ingredient in many classic Korean dishes, including:
- Bulgogi Marinated Korean beef with a sweet and savory flavor.
- Jeyuk Bokkeum Spicy stir-fried pork seasoned with a balanced sauce.
- Galbi Korean marinated short ribs.
- Japchae Stir-fried glass noodles with vegetables and meat.

How to Choose Ganjang
For authentic Korean home cooking, I recommend choosing a Korean soy sauce made by Sempio, one of the most widely used soy sauce brands in Korea.
The two products below are suitable for everyday Korean cooking and are available on Amazon. There is no major difference in taste between them for most home cooking, so either one is a reliable choice.
RECOMMENDED
Sempio Naturally Brewed Soy Sauce 701
A naturally brewed Korean soy sauce with a deep, balanced flavor. It works well for marinades, stir-fries, dipping sauces, and everyday Korean cooking.
Its flavor is not dramatically different from Sempio Jin Gold F3 in most everyday Korean dishes.

RECOMMENDED
Sempio Jin Gold F3 Soy Sauce
A versatile Korean soy sauce with a savory, approachable flavor. It works well for stir-fries, marinades, seasoned vegetables, and everyday Korean dishes.
For typical home cooking, the taste difference between this and Sempio 701 is relatively small.
View on AmazonWHICH ONE SHOULD YOU CHOOSE?
Both products are suitable for general Korean cooking, and the difference in taste is not significant for most home recipes. Choose whichever one is easier to find or more reasonably priced.
For your first all-purpose Korean soy sauce, avoid products labeled Low Sodium or For Braising. These are designed for more specific uses and may not give you the balanced flavor expected in everyday Korean cooking.
Product availability and pricing may change on Amazon.
How to Store Ganjang
Once opened, Korean soy sauce can typically be stored for 6 months to 1 year.
Unless you live in an extremely hot climate, refrigeration is generally not necessary. Keep the bottle tightly sealed in a cool, dry place away from direct sunlight and excessive heat.
Substitutes for Ganjang
If your goal is to recreate authentic Korean flavors, there is no perfect substitute for Korean soy sauce.
Other soy sauces may work when nothing else is available, but the flavor will not be exactly the same. For the most authentic results, it is worth using a genuine Korean product.
Frequently Asked Questions
Is Ganjang vegan?
Many Korean soy sauces are vegan, including the Sempio products recommended above, which are made primarily from soybeans and wheat.
Always check the ingredient label because recipes and manufacturing processes can vary by product or region.
Can I eat Ganjang without cooking it?
Yes. In Korea, soy sauce is commonly served without additional cooking as a dipping sauce for jeon, dumplings, and fried foods.
Mixing in a little vinegar or Korean chili flakes is an easy way to make a more flavorful dipping sauce.
