What Is This Korean Dish?

Korean Perilla Seed Potato Soup, or Deulkkae Gamjatang, is a warm and comforting Korean soup made with potatoes, oyster mushrooms, and nutty perilla seed powder. Unlike spicy Korean stews, this dish has a mild, creamy, and deeply savory flavor.

Perilla seed powder gives the broth its distinctive richness and slightly earthy, nutty taste, while the potatoes become soft and tender as they cook. Oyster mushrooms add a pleasant texture and absorb the flavorful broth beautifully. Green onions provide a fresh finish, and toasted sesame seeds add a final touch of nuttiness.

This simple Korean soup is especially satisfying when served hot with a bowl of steamed rice. With only a few ingredients and four straightforward cooking steps, it is an approachable way to experience the comforting flavors of Korean home cooking.
