Gochugaru

Gochugaru is Korean sun-dried red chile pepper — seeded, dried in the sun, and coarsely ground into the distinctive bright red flakes used across Korean cooking. The specific chile variety grown for gochugaru in Korea produces a pepper with a moderate, fruity heat and a natural sweetness that distinguishes it from most other dried chili products.

The grinding process removes the seeds, which are the hottest part of the pepper. The result is a chili product that delivers noticeable heat while retaining strong fruity and slightly smoky notes. It is not a shy ingredient — a tablespoon turns things red and adds real heat — but it is more nuanced than its appearance suggests.

Two grind types

Coarse gochugaru (gochugaru in most contexts) is the standard form: irregular flakes with visible texture, similar in appearance to Italian crushed red pepper but larger and more uneven. This is the correct form for kimchi, where the texture contributes to the final product's consistency and helps the paste adhere to the vegetables.

Fine gochugaru (gochugaru garu) is more finely ground, closer to a powder. Used in sauces, dipping pastes, and applications where a smooth texture is preferred. Some recipes specify one or the other; when unspecified, coarse is the default.

Why gochugaru is not interchangeable with Italian crushed red pepper

The Italian product — dried Calabrian or generic red chile flakes — has a sharper, less sweet heat with a different flavor profile. It is a functional substitute in a pinch, but it is not the same ingredient.

Gochugaru is drier and more powdery in texture. It has a clearly fruity, almost paprika-adjacent sweetness that Italian flakes don't have. The heat is also different: gochugaru sits around 1,500–10,000 Scoville units (mild to moderate); Italian crushed red pepper varies widely but often hotter and less sweet-forward.

In Korean cooking, the specific flavor of gochugaru is load-bearing. For kimchi in particular, there is no real substitute that produces the same result — the sweetness of the pepper is part of the fermentation chemistry, not just the flavor profile.

Essential applications

Kimchi: Gochugaru is the red color, the heat, and a significant portion of the flavor in kimchi. The coarse grind is used. There is no substitute that produces authentic kimchi.

Gochujang base: Gochugaru is one of the primary ingredients in gochujang (Korean fermented chili paste), along with fermented soybeans, rice, and salt. Understanding gochugaru helps explain gochujang's flavor.

Banchan seasoning: Most Korean side dishes that have any heat — spinach namul, kongnamul, seasoned cucumbers — use gochugaru as the primary seasoning agent.

Soups and stews: Sundubu jjigae, yukgaejang, and many other Korean soups bloom gochugaru in oil at the start of cooking to release its color and flavor into the fat, which then coats everything else in the pot.

Where to buy and storage

Available at Korean and Asian grocery stores in large bags (500g–1kg) for significantly less than the small bottles sold in Western supermarkets. The large bags are worth buying — you will use it. Store in an airtight container in a cool, dark place. For extended storage (more than a few months), the freezer preserves color and flavor well. Gochugaru fades from bright red to dull orange over time, which indicates flavor loss.
