Pressure Cooker Pork Belly Chashu Recipe

Sweet, savory, and meltingly soft pork belly chashu is a perfect topping for a bowl of piping hot ramen. This pressure cooker version turns a four-hour process into an hour and a half.

Why It Works

  • Using a pressure cooker cuts down the time it takes to transform tough pork belly into exceedingly tender slices of savory, sweet meat.
  • Rolling and tying the pork belly creates an aesthetically pleasing shape and achieves a sliceable texture rather than the fall-apart meat that pressure-cooking is best known for.
  • Chilling the cooked pork thoroughly makes it easier to cut uniform, thin slices for serving.

This is a pressure cooker adaptation of our popular braised pork belly chashu, the meltingly soft, seasoned pork that often crowns a bowl of piping hot ramen. Instead of cooking the belly low and slow in the oven for three to four hours, we turn to the pressure cooker to achieve a similar, if not identical, near-collapsing texture in about an hour and a half.

This recipe hews as closely as possible to the original, but attentive readers will note one small difference: The alcohol in the sake is cooked off before adding it to the pot, and the amount of sugar in the recipe has been halved. After testing the recipe several times, we found that neglecting to cook off the alcohol in the sake led to an overwhelming and off-putting alcohol flavor in the pork. However, we also discovered that cooking off the alcohol concentrated the sugar content, which led to the pork being a little too sweet for tasters.

Some tasters found the finished pork belly slices to be a little less savory than they liked, so do note that there is an optional step for seasoning the slices with a touch of salt right after torching.

The pork belly slices work well in any bowl of ramen you might make. That can be from an instant packet, or you can make your own creamy pork bone–based ramen (tonkotsu), a creamy chicken bone–based ramen (tori paitan), a soy sauce–flavored ramen (chintan shoyu), or a salt-flavored ramen (shio).

Rate & Comment


  • 1 cup (240 ml) sake

  • 1 cup (240ml) mirin

  • 1/2 cup (120ml) soy sauce

  • 1/4 cup (50g) sugar

  • 6 scallions, roughly chopped

  • 6 whole garlic cloves

  • One 2-inch knob ginger, unpeeled, sliced into 1/2-inch-thick pieces

  • 1 large shallot, unpeeled, halved

  • 2-pound (900g), skin-on slab of boneless pork belly

  • Kosher salt


  1. In small saucepan, bring sake to a boil over medium-high heat, and cook until reduced by half and alcohol has cooked off, about 5 minutes. Transfer reduced sake to pressure cooker pot along with mirin, soy sauce, sugar, scallions, garlic, ginger, and shallot. Set aside.

  2. Lay pork belly on cutting board and roll up tightly lengthwise, with skin facing out.

  3. Using butchers twine, tightly secure pork belly at 3/4-inch intervals.

  4. Add pork belly to pressure cooker pot (it won't be submerged). If using an electric pressure cooker, cover and seal the pot, set the pressure cooker to "high pressure" and set the cook time to 1 hour and 30 minutes. If using a stovetop pressure cooker, cover and seal the pot, set it over medium-high heat, and allow to come to pressure. Cook at high pressure for 1 hour and 30 minutes. Allow pressure to release naturally, or manually release pressure. Pork belly should be fully tender, offering little resistance when poked with a cake tester or paring knife at its center.

  5. Using a spatula and tongs, carefully transfer pork (it will be very soft) to a large container. Strain cooking liquid through fine-mesh strainer into container with pork. Cool at room temperature, then cover container tightly and refrigerate until pork is completely chilled, at least 6 hours.

  6. When ready to serve, remove pork belly from container, wiping off excess cooking liquid; reserve cooking liquid for another use (like making ajitsuke tamago or braising more pork in the future). Slice pork belly crosswise 1/4-inch-thick pieces, removing and discarding twine as you go (if you are not serving all of the pork at once, do not remove all of the twine, as it helps hold the shape of the chashu and makes it easier to slice).

  7. To Serve: Pork belly slices can be seasoned with salt to taste and placed directly on top of a bowl of piping hot ramen. Alternatively, slices can be torched or broiled before serving.

  8. If using a broiler, set rack 2 to 3 inches from broiler element, and preheat broiler on high. Place pork belly slices on rimmed baking sheet and broil until slices are warmed through, fat is bubbling, and some light charring occurs, 1 to 2 minutes, depending on the strength of the broiler. Season pork belly slices with salt to taste. Place atop piping hot bowls of ramen.

  9. If using a kitchen torch, place pork belly slices on rimmed baking sheet. Turn torch on, making sure the flame is blue (which indicates full combustion of the gas), then direct the flame at the surface of the meat, holding torch 4 to 5 inches above meat. Cook until fat is bubbling, some light charring occurs, and meat is warmed through, about 30 seconds. Season pork belly slices with salt to taste. Place atop piping hot bowls of ramen.
