Yangnyeom Gejang: Korea’s Spicy Marinated Crab Explained

Yangnyeom Gejang (양념게장) is a bold and flavorful Korean dish made by marinating raw kkotge crabs in a spicy, sweet, and savory chili-based sauce. Often referred to as “rice thief” (밥도둑) alongside its soy sauce counterpart, Ganjang Gejang, this chili crab dish is beloved for its intense flavor and melt-in-your-mouth crab meat. If you’re a fan of spicy seafood or adventurous culinary experiences, Korean chili crab (Yangnyeom Gejang) is a must-try.

1. What Is Yangnyeom Gejang?

Korean chili crab (Yangnyeom Gejang) is made by soaking fresh raw crabs (usually kkotge crabs) in a vibrant red pepper paste (gochugaru)-based sauce. The seasoning blend typically includes Korean red pepper flakes, garlic, ginger, soy sauce, sugar, sesame oil, and often a touch of plum extract or corn syrup for balance. After marination, the crabs absorb the complex layers of heat, sweetness, and umami, creating a flavor-packed experience.

2. Why Is It Called a “Rice Thief”?

Just like its soy-based sibling, Korean chili crabs (Yangnyeom Gejang) earned the nickname “rice thief“ because it pairs so perfectly with plain steamed rice. The spicy-sweet marinade seeps into every corner of the crab, and each bite practically demands a mouthful of warm rice. The dish is deeply satisfying without needing many side dishes.
