Pork Belly for Ramen
Description
Classic Japanese chashu—thick slabs of pork belly braised low and slow until impossibly tender, then finished with a glossy lacquer of soy, mirin, and sake. Sliced into rounds and stacked over bowls of ramen, this is the crown jewel of any tonkotsu or rich noodle soup.
Ingredients
Pork
- 2–3 pounds thick-cut pork belly (5- to 7-layer skin-on preferred), in ½-inch-thick slabs
- Kosher salt and black pepper
- 2 tablespoons neutral oil (canola or vegetable)
Braising Liquid
- 1 cup water
- ⅓ cup soy sauce
- ⅓ cup sake
- ¼ cup mirin
- 2 tablespoons brown sugar or coconut sugar
- 4 scallions, roughly chopped
- 8 cloves garlic, smashed
- 1-inch piece ginger, sliced into coin rounds
- 1 small shallot, halved
Tying (optional but recommended)
- Butcher's twine for tying rolled pork
Instructions
- If using thick belly slabs, pat the pork completely dry and season liberally with salt and pepper on both sides. For the classic spiral-chashu look, roll each slab tightly into a cylinder and tie with butcher's twine at 1-inch intervals to hold its shape.
- Heat oil in a Dutch oven or heavy-bottomed pot over medium-high heat. Sear the pork fat-side down first until deeply golden brown, about 3–4 minutes. Flip and sear all remaining sides until uniformly caramelized. This step builds the fond (browned bits) that enriches the braise.
- Remove the pork from the pot and set aside. Make sure to drain excess rendered fat if there's more than a tablespoon in the bottom.
- To the same pot, add water, soy sauce, sake, mirin, sugar, scallions, garlic, ginger, and shallot. Bring the liquid to a boil over high heat while scraping up all the caramelized fond from the bottom with a wooden spoon.
- Place the seared pork back into the pot, ensuring it is mostly submerged in the braising liquid. If not fully covered, add more water as needed.
- Reduce heat to very low so the liquid barely simmers (tiny bubbles at the edges). Cover tightly with a lid. Transfer to a 300°F (150°C) oven for 2–2.5 hours, OR continue on stovetop on the lowest possible simmer. The pork is done when a knife slides through with zero resistance and it feels nearly jiggly.
- While the pork rests still warm in its braising liquid for another 30 minutes (this step makes it even more tender), bring the remaining braising liquid to a rolling boil over high heat and reduce it by about one-third, creating a thicker lacquer/glaze. Return the pork and all resting juices into this reduced glaze.
- Remove pork from the pot and allow it to cool slightly (or chill completely in the fridge overnight for even better slicing). Slice crosswise into ¼-inch-thick rounds and arrange atop ramen bowls.
Notes
- The "overnight rest" trick: letting chashu sit in its braising liquid in the refrigerator overnight is a pro move. The cold-set belly slices much cleaner, and the reabsorption of glaze intensifies the flavor.
- Store leftover chashu refrigerated for up to 5 days. Re-slice when ready—it actually gets better each day as the flavors penetrate deeper.
- You can use pork shoulder (Boston butt) instead—this is called "buta no shoku" in Japan and has a slightly different, more meaty texture rather than the marbled fat layers of belly.
- The braising leftover liquid makes an incredible ramen soup base add-in or stir-fry sauce. Don't waste it.
- For extra smoky depth, finish sliced chashu with a quick sear on a hot cast iron skillet before plating.
