  • Total Time: 6 hours 45 minutes
  • Yield: 4 servings

Ingredients

Scale
  • 2 pounds pork bones (preferably trotters and neck bones)
  • 1 onion, halved
  • 2 cloves garlic, smashed
  • 1-inch piece ginger, sliced
  • 2 green onions
  • 2 tablespoons sesame oil
  • 4 servings ramen noodles (buy fresh or dried)
  • Soft-boiled eggs (marinated in soy sauce)
  • Sliced pork belly or chashu
  • Fresh toppings: bamboo shoots, nori, green onions, corn
  • Salt and pepper to taste
  • Optional: soy sauce, miso paste for additional flavor

Instructions

  1. Rinse pork bones thoroughly under cold water to remove impurities.
  2. Place bones in a large stockpot, cover with cold water, and bring to a boil. Reduce to a simmer and skim off foam.
  3. Add garlic, ginger, and green onions, then simmer uncovered for at least 6 hours, skimming excess fat occasionally.
  4. Towards the end, add soy sauce or miso paste for umami flavor, if desired.
  5. Strain the broth through a fine sieve to remove bones and solids; set aside.
  6. Cook ramen noodles in boiling water until just tender. Drain and rinse with cold water.
  7. Prepare toppings: soft-boil eggs for 6-7 minutes, marinate in soy sauce, slice pork belly, and prepare vegetables.
  8. Divide noodles into bowls, ladle hot broth over, and garnish with toppings. Finish with a drizzle of sesame oil.

Notes

  • Use pork trotters and neck bones for a rich, gelatinous broth.
  • Simmer broth for at least 6 hours for authentic flavor.
  • Marinate soft-boiled eggs in soy sauce for added savory taste.
  • Adjust seasoning with soy sauce or miso paste during cooking.
  • For vegetarian version, substitute with mushroom and vegetable broth, adding umami ingredients.
