Authentic Tonkotsu Ramen
Rich Pork Bone Broth
A classic Japanese Tonkotsu ramen featuring a rich, creamy pork bone broth slow-simmered to perfection, paired with chewy noodles and authentic toppings.
Tonkotsu ramen is a beloved staple of Japanese cuisine, renowned for its luxuriously opaque, collagen-rich pork bone broth. Achieving this signature milky texture requires patience and a low, steady simmer to fully dissolve the marrow. The resulting soup provides a deeply savory canvas for chewy noodles, chashu pork, and fresh garnishes.
Ingredients
- 1.5 kg pork bones
- 1 large onion
- 1 large carrot
- 3 stalks green onions
- 1 piece ginger
- 4 cloves garlic
- 4 portions fresh ramen noodles
- 4 whole soft-boiled eggs
- 4 small bok choy
- to taste salt
- to taste pepper
- 1 tbsp chicken bouillon
- to taste seaweed (nori)
- optional chashu pork slices
- optional menma (bamboo shoots)
- optional sweet corn
- optional wood ear mushrooms
Instructions
- 1Prepare the aromatic vegetables

Chop the onions, carrots, green onions, ginger, and garlic into small, uniform pieces. Having your ingredients prepped and organized, known as mise en place, makes the cooking process smoother and more efficient.
Tip: Cut the vegetables into similar sizes to ensure they cook evenly and release their flavors consistently into the broth. - 2Boil the aromatic base

Place the prepared onions, carrots, green onions, ginger, and garlic into a pot with an appropriate amount of water. Bring the mixture to a boil over high heat, then reduce the heat to low and let it simmer for 30 minutes to infuse the water with flavor.
Tip: Keep the pot covered during the simmer to help retain heat and prevent the aromatic liquids from evaporating too quickly. - 3Strain the vegetable broth

After 30 minutes of simmering, carefully remove all the vegetable ingredients from the pot. Discard the solids and keep the clear, flavorful vegetable-infused liquid, which will serve as the foundation for your soup base.
Tip: Use a fine-mesh sieve or slotted spoon to ensure all small bits of ginger or onion are completely removed for a cleaner broth. - 4Simmer the pork bones

Gently place the prepared pork bones into the pot with the vegetable broth base. Bring the water back to a boil over high heat, then lower the heat and cook for 60 minutes. Bring to a high boil again, then lower the heat and simmer for another 2 hours until the marrow and collagen dissolve completely into a rich, creamy soup.
Tip: Simmering the bones slowly is the key to achieving the signature creamy, rich texture of a true Tonkotsu broth. - 5Cook the ramen noodles

Place the ramen noodles into the pot of boiling water. Cook until the noodles are thoroughly cooked through, then remove them and place them into a serving bowl.
Tip: Keep an eye on the noodles to ensure they remain chewy and do not overcook.
