Ingredients

  • 4 lb pork bones (femur or neck bones)
  • 1 lb pork belly (for chashu)
  • 4 servings fresh ramen noodles
  • 4 large eggs
  • 6 cloves garlic, smashed
  • 1 thumb ginger, sliced
  • 2 green onions, white parts only
  • 1/2 cup soy sauce
  • 1/4 cup mirin
  • 2 tbsp sake
  • 2 tbsp sugar
  • 4 sheets nori (dried seaweed)
  • 2 tbsp sesame oil
  • White pepper and salt to taste

Instructions

1

Prepare the pork bones

Place pork bones in a large pot and cover with cold water. Bring to a boil and cook for 10 minutes. Drain, rinse the bones thoroughly, and scrub the pot clean. This removes impurities for a clear, clean broth.

2

Make the broth

Return bones to the pot and cover with fresh water. Add garlic, ginger, and green onions. Bring to a rolling boil, then reduce to a vigorous simmer. Cook for 3 hours, adding water as needed to keep bones submerged. The broth should be milky white and rich.

3

Prepare the chashu

While the broth simmers, roll the pork belly tightly and tie with kitchen twine. In a separate pot, combine soy sauce, mirin, sake, sugar, and 1 cup water. Add the pork belly roll, bring to a boil, then simmer for 1 hour. Let cool in the liquid, then slice into rounds.

4

Make soft-boiled eggs

Bring water to a gentle boil. Carefully lower the eggs in and cook for exactly 6 minutes 30 seconds. Transfer to an ice bath. Peel and marinate in the cooled chashu liquid for at least 30 minutes.

5

Cook the noodles

Cook the ramen noodles according to package directions, usually 1-2 minutes. Drain well and divide among 4 deep bowls.

6

Assemble the bowls

Ladle the hot tonkotsu broth over the noodles. Top with slices of chashu, a halved soft-boiled egg, a sheet of nori, and sliced green onions. Drizzle with sesame oil and sprinkle with white pepper. Serve immediately.

Tips & Tricks

  • The key to milky white tonkotsu broth is a vigorous, rolling boil — don't let it simmer gently.
  • Blanch the bones thoroughly to remove any blood and impurities for a clean flavor.
  • Prep the chashu and eggs a day ahead for easier assembly and deeper flavor.
  • Customize your bowl with extras like corn, butter, sesame seeds, or chili oil.
