Homemade Thick Chashu Tonkotsu Ramen
Master the art of tonkotsu at home with this rich, creamy pork bone broth and melt-in-your-mouth braised chashu pork. A restaurant-quality bowl built from scratch.
Tonkotsu ramen is the ultimate comfort food, renowned for its opaque, creamy pork bone broth and deep, savory flavor. Achieving that signature silkiness requires patience, starting with a thorough blanching of the bones followed by a long, steady simmer. This recipe pairs that intense broth with tender, soy-braised pork belly, seared to perfection for a smoky finish that completes this classic Japanese noodle bowl.
Ingredients
- 2 kg pork marrow and neck bones
- 500 g pork belly slab
- 200 g ramen noodles
- 1 whole onion
- 1 head garlic
- 50 g fresh ginger
- 100 ml soy sauce
- 50 ml cooking wine
- to taste green onions
- to taste sweet corn
- to taste bamboo shoots
- to taste wood ear mushrooms
- to taste fried shallots
- 1 soft-boiled egg
Instructions
- 1Blanch the pork bones

Place the pork bones into a large stockpot and cover with cold water. Bring the water to a rolling boil to draw out any impurities, blood, and odors from the bones. Once boiling, skim off any foam that rises to the top.
Tip: Starting with cold water is essential for drawing out impurities thoroughly before the actual broth-making process begins. - 2Sear the blanched bones

Remove the blanched pork bones from the pot and transfer them to a hot wok. Sear the bones until they are lightly browned on all sides to enhance the depth and richness of the final tonkotsu broth.
Tip: Make sure the wok is sufficiently hot before adding the bones to get a good char without sticking. - 3Begin the broth base

Carefully pour boiling water over the seared pork bones in the cooking pot. Using hot water helps maintain the cooking temperature and immediately begins the process of emulsifying the fats and proteins to create a creamy tonkotsu broth.
Tip: Pouring hot water instead of cold water helps prevent the temperature from dropping, which keeps the cooking process consistent. - 4Add aromatics to the broth

Add a whole onion, cloves of garlic, and fresh ginger slices into the pot with the simmering bone broth. These aromatics will infuse the liquid with essential savory and spicy notes, balancing the richness of the pork bones.
Tip: Crush the ginger and garlic slightly before adding to the pot to help release their oils more effectively into the broth. - 5Tie the pork belly

Take a slab of pork belly and roll it tightly. Secure the roll using kitchen twine, tying it firmly at regular intervals. This ensures the chashu maintains a uniform, compact shape during the long braising process.
Tip: Tying the meat tightly is crucial for uniform cooking and makes it much easier to slice into clean rounds once chilled. - 6Parboil the pork belly

Place the tied pork belly into a pot of boiling water along with green onions and a splash of cooking wine. Allow it to parboil briefly, which helps to firm up the meat and remove any residual impurities before the main braising step.
Tip: The cooking wine and green onions help neutralize any strong pork odors during this initial parboiling stage. - 7Braise the pork belly

Place the tied pork belly into a pot with onion, ginger, and garlic. Pour in a soy sauce-based braising liquid, ensuring the pork is partially submerged to absorb the flavors during the slow cooking process.
Tip: Tie the pork belly with kitchen twine to help it maintain its shape while it braises and becomes tender. - 8Slice the braised pork belly

Carefully slice the tender, braised pork belly into thick, uniform pieces using a sharp knife. Ensure each slice is consistent to provide the perfect portion for the tonkotsu ramen bowl, showcasing the rich, melt-in-your-mouth texture achieved through long cooking.
Tip: Use a gentle sawing motion with the sharpest knife available to keep the soft, braised meat from crumbling. - 9Sear the chashu

Place the sliced chashu pork in a cast-iron pan. Use a kitchen torch to sear the surface of the pork slices directly, creating a caramelized and charred finish that adds a smoky flavor.
Tip: Keep the torch moving constantly to ensure an even char without burning the meat. - 10Assemble the ramen

Place cooked ramen noodles into a serving bowl. Carefully pour the hot, prepared tonkotsu broth over the noodles, ensuring they are fully submerged and ready for toppings.
Tip: Ensure your serving bowl is pre-warmed so the broth stays hot longer while eating.
