A rich and savory homemade Tonkotsu Ramen featuring tender slow-cooked pork leg bone, springy bamboo noodles, and a crystal-clear seasoned broth.

↓ The ingredients ↓ The steps

Tonkotsu ramen is traditionally celebrated for its rich, cloudy broth, but this comforting home-style version takes a streamlined approach using pork leg bones simmered in a rice cooker. Infused with aromatic angelica root and scallion white, the broth is carefully strained to achieve a clear, deeply savory soup base that pairs beautifully with tender marrow-filled meat and fresh bamboo noodles.

    Take the blanched pork bones out of the pot and rinse off any remaining surface foam or residue using hot water.

    Tip: Always use hot water when rinsing blanched meat to prevent the pores from closing and locking in impurities.

    Tip: Make sure the pot is clean before adding the bones.
  4. 4Add Angelica Root

    Add a slice of angelica root into the pot along with the pork bones for a distinct herbal aroma.

    Tip: Angelica root adds a distinctive herbal aroma to the broth.
  5. 5Add Scallion White

    Tip: Using a rice cooker is a convenient way to simmer bone broths effortlessly.
  7. 7Simmer and Skim Foam
    A skimmer tool held over the simmering broth in the rice cooker to remove impurities.

    Set the rice cooker to cook for 45 minutes with the bones, angelica root, scallions, and water, opening the lid occasionally to skim off surface foam for a clear broth.

    Tip: Skimming regularly ensures a clean and clear soup base.
  8. 8Season with Salt
    The broth actively bubbling and boiling inside the rice cooker pot.

    Add salt to the simmering broth inside the rice cooker to properly season the soup base.

    Tip: Season gradually and taste the broth to get the right balance.
