How to Make Delicious Korean Bracken (Gosari) Namul — Safe, Healthy, and Packed with Tradition

“Learn how to cook delicious and safe Korean bracken (gosari) namul — from traditional detoxifying methods to flavor-boosting tips and rich health benefits. Perfect spring side dish for your table.”

 

Today, I’m sharing how I prepare Korean bracken (gosari) namul, a spring vegetable dish that’s deeply rooted in our food culture.

It’s fascinating — in the West, bracken is sometimes avoided because raw bracken contains a natural toxin called ptaquiloside.

But long ago, Korean ancestors discovered how to make it safe: boiling, soaking, and drying. This traditional process, called “dechigo urenegi” (blanching and soaking), removes most of the harmful substances and brings out its deep, earthy flavor. Thanks to that wisdom, we can enjoy this seasonal dish safely today.

🧪 Safety — Debunking Myths

Raw bracken does have ptaquiloside, but boiling and soaking for hours removes over 90%, according to Korea’s Rural Development Administration.

WHO and FAO also recognize that properly cooked bracken is safe to eat.

 

There’s also a myth that “bracken contains too much carbon and causes cancer.”

This is false — all plants are carbon-based, and carbon itself is not carcinogenic.

Properly prepared bracken has no proven link to cancer.

• 1 Tbsp sesame oil

🍳 How to Cook

1. Soak
Soak dried bracken in plenty of water for 6–8 hours (overnight works well).
Change water once or twice to clean away dust and bitterness.

2. Boil
Bring 1.5 L of water to a boil, add 1 Tbsp salt, and simmer bracken for 20–30 minutes until tender.
Rinse under cold water several times, squeeze gently to remove excess water, and cut into 2–3 inch pieces.

3. Season & Stir-fry
Mix bracken with soy sauce, sesame oil, perilla oil, and garlic.
Stir-fry gently with a splash of cooking oil over medium heat for 5 minutes.
Finish with roasted sesame seeds.

✨ Flavor Boosting Secrets

• Add a splash of onion or pear juice — subtle sweetness and umami.
• Use anchovy or kelp broth instead of plain water for a deeper taste.
• Finish with a spoon of perilla seed powder for rich nuttiness.
• Let it marinate for 10 minutes before stir-frying to help flavors soak in.
