How to Make Irresistible Tonkotsu Ramen | Homemade Chashu & Black Garlic Oil

1. Start by blanching the pork bones in 1 cup boiling water for 10 minutes to remove impurities, then drain and rinse the bones thoroughly under cold water.
2. Place the cleaned bones, onion, garlic head, and sliced ginger into a large stockpot with 12 cups of fresh water; bring to a boil, then reduce heat to a gentle simmer. Cook uncovered for 7-8 hours, occasionally skimming off any scum that rises to the surface to keep the broth clear and flavorful.
3. While the broth simmers, prepare the chashu pork by combining soy sauce, sake, mirin, sugar, crushed garlic, ginger slices, and water in a pot. Add the rolled pork belly, bring to a simmer, then cover and cook gently for 2 hours until tender and flavorful. Once done, let it cool in the braising liquid before slicing thinly.
4. To make black garlic oil, heat vegetable oil and sesame oil in a small pan over low heat. Add minced garlic and cook slowly, stirring often, until the garlic turns dark brown but not burnt, about 10-12 minutes. Remove from heat and stir in black sesame seeds if using. Set aside to cool.
5. Before serving, cook fresh ramen noodles according to package instructions until just tender. Drain well.
6. Reheat the tonkotsu broth and season with salt to taste. To assemble, divide noodles into bowls, ladle hot broth over them, then top with sliced chashu, halved soft-boiled eggs, green onions, bean sprouts, and nori strips. Drizzle 1-2 teaspoons of black garlic oil over each bowl for a delicious savory finish.
7. Serve immediately and enjoy your rich, creamy, and utterly irresistible tonkotsu ramen!

Tips for the Best Results

• Use pork trotters along with neck bones for extra collagen and broth richness.
• Simmer the broth gently to prevent cloudiness and maintain a creamy texture.
• Make black garlic oil slowly on low heat to avoid burning and bitterness.
• Slice chashu thinly for easier, more flavorful bites in every spoonful.
• Customize toppings like bamboo shoots or corn to add extra texture and sweetness.

Storage and Reheating

You can refrigerate leftover broth and chashu separately in airtight containers for up to 3 days. Store noodles and toppings separately to keep textures fresh.

Reheat the broth gently on the stovetop, avoiding boiling to maintain creaminess. Warm chashu slices in the broth or microwave briefly. Cook fresh noodles before serving if possible to preserve their springy texture.

Frequently Asked Questions

Can I use store-bought broth instead of making tonkotsu broth?

While homemade tonkotsu broth provides the richest flavor and creaminess, you can use store-bought pork broth as a shortcut. Just keep in mind it won’t have quite the same depth and body as the slow-simmered version.

How do I know when the chashu pork is done?

The chashu is done when it’s tender enough to slice easily with a knife and has absorbed the braising liquid’s flavors. This usually takes about 2 hours of gentle simmering.

What makes black garlic oil special in tonkotsu ramen?

Black garlic oil adds a deep, roasted garlic aroma and umami that complements the creamy pork broth perfectly. It enhances flavor complexity and gives the dish an irresistible finishing touch.

Can I prepare parts of this recipe ahead of time?

Absolutely! The broth can be made a day or two in advance and refrigerated. Chashu also tastes better after resting overnight in its braising liquid, so preparing them ahead will improve flavor.
