📝 About This Recipe

Gosari-namul is a quintessential Korean side dish celebrated for its deep, earthy flavor and uniquely meaty texture. Often referred to as 'mountain beef,' these rehydrated bracken fern shoots are a staple of the Korean Royal Court and a mandatory component of a classic Bibimbap bowl. This recipe transforms the fibrous greens into a tender, savory delicacy using a traditional slow-simmering technique and the rich depth of toasted sesame and garlic.

🥗 Ingredients

Main Ingredients

  • 100 grams Dried Bracken Fern (Gosari) (or 400g of pre-soaked/boiled fern from a Korean market)
  • 8 cups Water (for boiling the dried fern)

The Seasoning Base

  • 2 tablespoons Soup Soy Sauce (Guk-ganjang) (essential for authentic salty depth)
  • 1 tablespoon Regular Soy Sauce (for color and sweetness)
  • 3 cloves Garlic (finely minced)
  • 2 stalks Green Onion (finely chopped, white and light green parts)
  • 1 tablespoon Toasted Sesame Oil (high quality for best aroma)
  • 1 tablespoon Perilla Oil (adds a traditional nutty, floral note)

Cooking Liquid and Finishing

  • 1/2 cup Anchovy Kelp Broth (or water for a vegan version)
  • 1 tablespoon Toasted Sesame Seeds (slightly crushed to release oils)
  • 1 tablespoon Cooking Oil (neutral oil like grapeseed or vegetable)
  • 1/2 teaspoon Sugar (to balance the bitterness of the fern)

👨‍🍳 Instructions

  1. 1

    If using dried bracken, soak it in plenty of cold water overnight (at least 8-12 hours) until the stems are pliable.

  2. 2

    Place the soaked fern in a large pot with the soaking water. Bring to a boil, then reduce heat and simmer for 30-40 minutes until the thickest part of the stem can be easily pinched flat.

  3. 3

    Turn off the heat and let the fern sit in the hot water for another 30 minutes to ensure maximum tenderness. Drain and rinse thoroughly in cold water 2-3 times.

  4. 4

    Trim off any woody, tough ends from the fern. Cut the tender stems into manageable 2-3 inch (5-7 cm) lengths.

  5. 5

    In a large mixing bowl, combine the cut bracken fern with the soup soy sauce, regular soy sauce, minced garlic, chopped green onions, and sugar.

  6. 6

    Massage the seasoning into the fern by hand for about 2 minutes. This 'son-mat' (hand-taste) ensures the flavors penetrate deep into the fibers.

  7. 7

    Heat a large skillet or wok over medium heat and add the neutral cooking oil and perilla oil.

  8. 8

    Add the seasoned bracken fern to the skillet. Sauté for 3-4 minutes, stirring constantly to release the aromatics.

  9. 9

    Pour in the anchovy broth (or water). Reduce the heat to low-medium, cover with a lid, and let it braise for 5-7 minutes. This step is crucial for the 'meaty' texture.

  10. 10

    Remove the lid and increase the heat slightly. Stir-fry until most of the liquid has evaporated, leaving the fern glossy and moist but not swimming in sauce.

  11. 11

    Turn off the heat. Drizzle with the toasted sesame oil and sprinkle with the crushed toasted sesame seeds.

  12. 12

    Give everything a final toss to combine. Taste and add a pinch of salt if necessary, though the soy sauce should provide enough saltiness.

  13. 13

    Transfer to a serving plate and allow it to cool slightly; namul is traditionally served at room temperature or chilled.

💡 Chef's Tips

Always check the toughness of the stems after boiling; if they aren't tender, your final dish will be chewy. Using 'Guk-ganjang' (Soup Soy Sauce) is the secret to an authentic flavor as it is saltier and lighter in color than regular soy sauce. Perilla oil provides a specific 'mountain' fragrance that defines this dish, but you can use extra sesame oil if it's unavailable. Don't skip the 'massaging' step; it breaks down the plant fibers and allows the seasoning to permeate the fern. If using pre-boiled fern from the store, still give it a quick 5-minute blanch in boiling water to remove any 'packaged' smell.

🍽️ Serving Suggestions

Serve as a primary topping for a colorful Bibimbap bowl along with gochujang and a fried egg. Pair with grilled meats like Galbi or Bulgogi to provide an earthy contrast to the sweet marinades. Include it as part of a traditional 'Sanchae' (mountain vegetable) platter with steamed rice. Enjoy alongside a cold glass of Makgeolli (Korean rice wine) for a rustic snack. Serve with a hot bowl of Doenjang Jjigae (soybean paste stew) for a comforting, vegetarian-friendly meal.
