Born in Kurume, Fukuoka Prefecture in the 1940s, tonkotsu ramen is the soul of Kyushu's street food culture, built on a rich, milky pork bone broth that simmers for hours until deeply opaque and intensely savory. Thin, straight wheat noodles swim beneath a blanket of chashu pork, soft-boiled egg, and fragrant garlic oil in a bowl that is equal parts comfort and craft.

Ingredients
2 lbs pork trotters, split by butcher
1 lb pork neck bones
1 lb pork belly, skin-on, rolled and tied
12 cups cold water
1 cup soy sauce
1/2 cup mirin
1/4 cup sake
2 tbsp granulated sugar
4 cloves garlic, smashed
1-inch piece fresh ginger, sliced
4 large eggs
4 portions fresh ramen noodles (approximately 5 oz each)
4 tbsp tare (see instructions)
3 tbsp white miso paste
2 tbsp toasted sesame paste
1 tbsp soy sauce (for tare)
1 tsp white pepper
4 tbsp garlic oil (6 cloves garlic minced and fried in 4 tbsp neutral oil until golden)
4 sheets nori, halved
4 stalks green onion, thinly sliced
1 cup bamboo shoots (menma), rinsed
1 tsp kosher salt
2 tbsp neutral oil (for searing pork belly)
Instructions
Place pork trotters and neck bones in a large stockpot, cover with cold water, and bring to a vigorous boil over high heat. Boil for 10 minutes until grey foam rises heavily to the surface, then drain completely and rinse every bone thoroughly under cold running water to remove all impurities. Clean the pot as well.
Return the blanched bones to the clean pot and add 12 cups of fresh cold water. Bring to a full rolling boil over high heat, then maintain a vigorous boil — not a simmer — for 3 to 4 hours, adding water as needed to keep bones submerged. This aggressive boiling is what emulsifies the collagen and fat, turning the broth milky white and creamy. You should end up with approximately 8 cups of finished broth.
While the broth boils, prepare the chashu pork belly. In a small saucepan, combine 1 cup soy sauce, 1/2 cup mirin, 1/4 cup sake, and 2 tbsp sugar over medium heat, stirring until sugar dissolves. Set this braising liquid aside. Heat 2 tbsp neutral oil in a heavy skillet over high heat and sear the rolled pork belly on all sides until deeply golden brown, about 8 minutes total.
Transfer the seared pork belly to a snug saucepan or Dutch oven, pour the braising liquid over it, and add 4 smashed garlic cloves and sliced ginger. Bring to a boil, then reduce heat to low, cover, and braise for 90 minutes, turning the pork every 30 minutes, until completely tender. Remove pork from liquid and cool slightly, then slice into 1/2-inch rounds. Reserve the braising liquid — this becomes part of your tare.
Prepare the soft-boiled ramen eggs (ajitsuke tamago). Bring a small pot of water to a boil, gently lower 4 eggs into the water, and cook exactly 6 minutes and 30 seconds. Transfer immediately to an ice bath for 5 minutes, then peel carefully. Place peeled eggs into 1 cup of the reserved chashu braising liquid diluted with 1/2 cup water, and marinate for at least 2 hours, or overnight in the refrigerator.
Prepare the garlic oil by heating 4 tbsp neutral oil in a small saucepan over medium-low heat. Add 6 cloves of minced garlic and fry gently, stirring constantly, for 4 to 5 minutes until golden and fragrant. Do not let it burn. Remove from heat and set aside.
Prepare the tare by whisking together 3 tbsp white miso paste, 2 tbsp toasted sesame paste, 1 tbsp soy sauce, 1/2 cup of the reserved chashu braising liquid, and 1 tsp white pepper in a small bowl until smooth. This concentrated seasoning paste will season each bowl individually.
Season the finished tonkotsu broth with 1 tsp kosher salt and taste — it should be rich and savory on its own. Keep the broth at a gentle simmer over low heat. Bring a large pot of unsalted water to a rolling boil for the noodles.
Warm 4 large ramen bowls by filling them with hot water for 2 minutes, then drain. Working quickly, add 1.5 tbsp of tare to the bottom of each warmed bowl. Cook one portion of fresh ramen noodles at a time in the boiling water according to package directions, usually 60 to 90 seconds for fresh noodles. Drain well and add directly to the bowl.
Ladle approximately 1.5 to 2 cups of hot tonkotsu broth into each bowl over the noodles and tare, and stir briefly to combine. Top each bowl with 3 to 4 slices of chashu pork belly, 1 marinated soft-boiled egg halved lengthwise, a small mound of bamboo shoots, 2 half-sheets of nori standing upright at the bowl's edge, a generous pinch of sliced green onions, and a drizzle of 1 tbsp garlic oil. Serve immediately.
