Chashu Pork is a tender, melt-in-your-mouth marinated and rolled pork belly braised in a deeply flavorful mixture of soy sauce, sake, and mirin. This classic topping adds rich umami and silky texture to ramen and also works beautifully in rice bowls, sandwiches, or as a make-ahead protein for weekday meals.

Chashu Pork Belly Recipe
This Chashu Pork Belly recipe gathers techniques from several classic approaches to produce a tender, flavorful piece of braised pork belly perfect for ramen. The pork is rolled, tied, and slow-braised in a balanced, slightly sweet soy-based braise until fork-tender. After cooling in the braising liquid, the meat firms up slightly, making it easy to slice thinly and reheat gently in ramen broth.
Slow braising concentrates the flavors and gives the pork a glossy, savory finish. The reserved cooking liquid can be reused to marinate soft-boiled eggs (ajitsuke tamago) or to add flavor back into your soup or rice dishes. Because the dish improves after resting, Chashu is an ideal make-ahead item for entertaining or for building a restaurant-style bowl of ramen at home.

How To Make This Recipe
Here is a clear overview of the process. Follow the detailed recipe card below while you cook for exact times and quantities.
- Prepare the pork belly: Roll the pork belly into a cylindrical shape and tie it with kitchen twine so the skin faces outward. This helps create even slices and a pleasing presentation.
- Create the braising liquid: Combine soy sauce, sake, mirin, water, sugar, garlic, sliced ginger, shallots, and green onions in an oven-safe pot large enough to submerge the pork.
- Braise gently: Bring the liquid to a boil, add the pork, then cover and transfer to a low oven (about 275°F / 135°C). Cook slowly for several hours until very tender.
- Chill overnight: Remove the pork from the oven and refrigerate it submerged in the braising liquid. Resting overnight concentrates the flavor and firms the meat for neat slicing.
- Slice and serve: Slice the roll lengthwise and then into thin rounds. Reheat slices gently in ramen broth or warm them briefly in the braising liquid before serving. Reserve the cooking liquid for marinating eggs or as a flavor booster.

Recipe FAQ
Store cooked pork belly in an airtight container, submerged in its cooking liquid, in the refrigerator for up to three days. Keeping it in the liquid helps preserve moisture and flavor.
Reheat sliced pork belly gently in ramen broth, or warm whole slices briefly in a saucepan with some reserved cooking liquid until heated through. Avoid high heat to prevent drying.
Yes. The pork benefits from cooling in its braising liquid overnight, which deepens flavor and makes slicing easier. It’s an excellent make-ahead element for an assembled ramen night.
If you prefer, use a mild chicken broth in place of some or all of the sake. Adjust sweetness by reducing the sugar or substituting honey. Keep in mind substitutions will alter the final flavor.
Building a full ramen bowl combines a rich broth, noodles, Chashu, and toppings like soft-boiled marinated eggs, scallions, and nori. Making each component—broth, noodles, and Chashu—at home lets you layer authentic flavors for a restaurant-quality bowl.
No special equipment is required beyond an oven-safe pot and kitchen twine to tie the pork. You may need to source sake and mirin if you don’t keep them on hand; many stores that sell international ingredients carry them.

Recipe Tips
Chashu is forgiving but pay attention while it’s braising. Start checking for tenderness at about the two-hour mark and then every 30 minutes until the meat is tender but not falling apart. The goal is a soft, sliceable texture—not a dry, overcooked loaf.
When chilling overnight, keep the pork submerged in the braising liquid. This keeps the surface moist and helps the meat to absorb more flavor. Use a plate or folded paper towel to hold the pork down so it marinates evenly.

What else can you do with the marinade?
The braising liquid is extremely useful. Save it to marinate soft-boiled eggs for ajitsuke tamago: soft-boil eggs and cool them in ice water, peel, then submerge in the cooled braising liquid. Place a paper towel on top to ensure the eggs stay immersed and marinate for 4–5 hours for best flavor.
The same liquid can flavor vegetables, warm rice, or be reduced slightly to glaze roasted vegetables or meats. Strain and refrigerate any unused liquid; it keeps well and adds instant depth to soups and sauces.
