Japanese tonkotsu ramen, with pork tenderloin on top! Complete with recipes for my favorite toppings - soy marinated eggs and black garlic oil (mayu). This recipe calls for a stock concentrate, which saves time and delivers SO much flavor!
Please note, this recipe calls for mostly prepared ingredients from other recipes shared on this site. The eggs should be a made a day ahead of time. The black garlic oil may also be made ahead if desired.
Combine the ½ cup of Somi or Kikkoman brand tonkotsu broth concentrate with 4 cups of water in a medium saucepan and bring to a gentle simmer to warm through. If using a different stock concentrate, please check the concentrate-to-water ratio because it may defer, and prepare ~4 cups of soup.
Begin boiling a large pot of water for the noodles. When the rest of the meal is almost ready, cook the noodles per package instructions, then transfer them directly into the serving bowls. Premium frozen ramen noodles are pre-cooked and typically only need 1-2 minutes of cook time.
If preparing baby bok choy: slice off the base, separate the leaves, and thoroughly rinse. These can be placed in the bowl raw if desired (my preferred method), or boiled for 1-2 minutes until softened, then placed in serving bowls.
When ready to serve - pour the broth into the serving bowls over top of the noodles. Slice the marinated eggs in half and place in the bowl with the yolk facing up. Top with the sliced pork tenderloin, green onions, and a dash of the black garlic oil.
