Japanese Pork Stew: A Cozy Nikujaga Recipe

Japanese pork stew, often made as a pork version of nikujaga, combines tender pork, potatoes, onions, and carrots in a savory-sweet broth seasoned with soy, mirin, and dashi. It is a home-style Japanese dish with variations from cook to cook, and the one-pot method lets the vegetables soak up the broth as they simmer.

Ingredients

1 lb (450 g) thinly sliced pork shoulder or pork loin, cut into 2-inch (5 cm) pieces
1½ lb (680 g) Yukon Gold or other waxy potatoes, peeled and cut into 1½-inch (4 cm) chunks
1 medium yellow onion (about 7 oz / 200 g), cut into thick wedges
1 medium carrot (about 4 oz / 115 g), peeled and cut into ½-inch (1 cm) half-moons
1 tablespoon (15 ml) neutral cooking oil, such as canola
2 cups (480 ml) dashi, homemade or prepared from dashi granules according to the package
3 tablespoons (45 ml) Japanese soy sauce
3 tablespoons (45 ml) mirin
2 tablespoons (30 ml) sake
1 tablespoon (12 g) granulated sugar
1 teaspoon (5 ml) toasted sesame oil, optional, for finishing
2 scallions (about 30 g), thinly sliced, for serving
4 cups (600 g) cooked Japanese short-grain rice, for serving

Instructions

Prepare the ingredients. Cut the potatoes into similar-sized chunks so they soften at about the same rate, and keep the onion wedges fairly thick so they do not disappear into the broth. Cut the carrot into half-moons and the pork into manageable pieces. If the pork is very thinly sliced, stack a few slices and cut them together; this makes them easier to brown and check with a thermometer. Measure the dashi, soy sauce, mirin, sake, and sugar before you start cooking.
Brown the pork. Set a heavy pot or Dutch oven over medium-high heat and add the neutral oil. When the oil shimmers, add the pork in a loose layer; work in batches if the pot is crowded. Cook for about 5 minutes, turning the pieces once or twice, until the surfaces are no longer raw-looking and have picked up a little color. The pork does not need to be fully cooked at this stage. Transfer it to a plate, leaving any rendered juices and oil in the pot.
Soften the vegetables. Add the onion and carrot to the same pot. Cook for about 4 minutes, stirring occasionally, until the onion begins to turn translucent around the edges. If the bottom looks dry, add a tablespoon of water rather than more oil. This brief cooking gives the vegetables a head start while keeping the onion wedges intact for the simmer.
Add the potatoes and broth. Return the pork and any juices to the pot, then add the potatoes, dashi, soy sauce, mirin, sake, and sugar. Stir gently to distribute the seasonings without breaking the potatoes. Bring the liquid just to a boil, which usually takes about 4 minutes. Skim off any foam that collects on the surface; this helps the finished broth taste clean.
Simmer until tender. Lower the heat to maintain a gentle simmer, cover the pot, and cook for 24 minutes. The broth should bubble softly rather than boil hard. Check that the potatoes are tender when pierced with a small knife and that the carrots are soft but not mushy. Check the thickest piece of pork with a food thermometer; USDA FSIS lists 145°F (63°C) with a 3-minute rest as the safe minimum for whole cuts of pork. If needed, simmer a few more minutes until the pork reaches that temperature.
Concentrate the broth and rest. Remove the lid and simmer for 5 minutes to reduce the liquid slightly. Taste the broth and adjust with a small splash of soy sauce if it needs more savoriness, or a pinch of sugar if you prefer a rounder sweetness. Turn off the heat and let the stew stand for 3 minutes so the pork completes its rest and the vegetables can settle into the seasoned broth. Add the sesame oil, if using, and scatter sliced scallions over the top.
Serve. Spoon the pork, potatoes, carrots, and onion into shallow bowls, then ladle broth over each portion. Serve hot with cooked rice alongside or underneath, so it can catch the savory-sweet sauce.

Tips

Choose potatoes that hold their shape. Yukon Golds and other waxy potatoes are dependable here. Starchy russets taste good but may break down during the covered simmer, making the broth cloudy and thick. Cut all the pieces to a similar size and avoid stirring vigorously once they are tender.
Use dashi for the characteristic flavor. Dashi is a Japanese stock often made with kombu seaweed and bonito flakes. Prepared dashi granules are a convenient option; follow the package directions and use the resulting stock in the measured amount. If dashi is unavailable, use low-sodium chicken broth, understanding that the stew will taste fuller and less distinctly Japanese.
Make practical swaps for mirin or sake. Mirin adds sweetness and a gentle acidity; if you cannot find it, use 2 tablespoons (30 ml) water mixed with 1 tablespoon (12 g) sugar in its place. The flavor will be less rounded. Sake can be replaced with the same amount of water or unsalted broth; omitting it makes the broth slightly less aromatic.
Keep the simmer gentle. A rolling boil can break the potatoes and make thin pork tough. If the stew is ready before you are, turn off the heat and keep the pot covered briefly rather than continuing to boil it. Taste only after the ingredients have simmered, since the broth becomes more concentrated as it reduces.

Serving Suggestions

Serve the stew in individual bowls with freshly cooked Japanese short-grain rice. Either keep the rice in a separate bowl or spoon the stew over it; the latter is especially useful when you want the broth to season every bite. A small side of quick-pickled cucumber or daikon adds a crisp, tart contrast to the soft potatoes and sweet onion. Steamed green vegetables, such as spinach or broccoli, also make a simple side without competing with the broth.

For a more traditional home-style spread, keep the portions modest and add miso soup or a small salad if desired. The stew itself is filling, so there is no need for elaborate accompaniments. Offer extra scallions at the table, and let each person add them to taste. If serving rice directly under the stew, add it just before eating so it stays warm and does not absorb all the broth while sitting.

Variations

Use another cut of pork: Thinly sliced pork belly makes a richer stew and releases more fat, so you may need less oil for browning. Pork loin is leaner and has a milder flavor; avoid simmering it longer than needed for tenderness and safe cooking. If your slices are especially thin, check the thickest folded piece carefully with a thermometer.

Add shirataki noodles: Rinse and drain about 7 oz (200 g) of shirataki noodles, cut them into shorter lengths, and add them with the broth. They contribute a pleasantly springy texture but absorb little flavor, so keep them in the seasoned liquid as it simmers. They can make the pot look fuller without changing the potato-to-broth balance much.

Change the vegetables: A handful of green beans or snow peas can be added during the final 3 to 5 minutes so they stay bright and crisp-tender. Mushrooms, such as shiitake, can go in with the onion and carrot; they bring an earthy flavor and release moisture, so allow the broth to return to a simmer before covering. These are useful home-style variations rather than fixed rules.

Adjust the sweetness and salt: Japanese soy sauces and dashi products vary in saltiness, while mirin brands vary in sweetness. Begin with the amounts listed, then make small adjustments at the end. A splash of water or dashi can soften an overly salty broth; a little additional sugar can balance a broth that tastes too sharp. Avoid adding extra soy sauce early, since it is harder to correct once the liquid reduces.

Storage and Reheating

Refrigerate the stew within 2 hours of cooking. Transfer it to a shallow, covered container so it cools promptly, and keep it refrigerated for 3 to 4 days. Store rice separately when possible; it is easier to reheat evenly and will not soak up the stew broth during storage. The potatoes may soften further after a night in the refrigerator, but the flavors often become more blended.

For longer storage, freeze the stew in airtight, freezer-safe portions for up to 2 months for best quality. Potatoes can become a little grainy after freezing and thawing, but the stew remains usable. Thaw it overnight in the refrigerator, or reheat directly from frozen over low heat with a splash of water or dashi to loosen the broth.

Reheat on the stovetop over medium-low heat, stirring gently and turning the larger pieces so they warm evenly. You can also microwave a covered portion, pausing to stir halfway through. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer. Heat only the amount you plan to eat, and avoid repeatedly cooling and reheating the full pot.

Frequently Asked Questions

Is Japanese pork stew the same as nikujaga?
Nikujaga is a Japanese home-style meat-and-potato stew, and pork is used in many versions. Some cooks use beef, while others choose pork; vegetables, sweetness, and broth strength also vary. This recipe follows the familiar combination of meat, potatoes, onion, and carrot in a dashi-based soy-seasoned broth, without claiming to represent every regional or family style.

Can I make this stew without dashi?
Yes. Low-sodium chicken broth is the easiest substitute, used in the same amount, though it gives the stew a more pronounced chicken flavor and less of the clean, seaweed-and-bonito character of dashi. You can also use water with a little dashi granule if available. Taste before adding more soy sauce, because prepared stocks differ in saltiness.

Why are my potatoes falling apart?
Very starchy potatoes, small uneven chunks, a vigorous boil, and frequent stirring can all cause the pieces to break. Use waxy or all-purpose potatoes, cut them into generous chunks, and keep the stew at a quiet simmer. Check tenderness near the end rather than cooking by the clock alone; once a knife slides in easily, reduce the heat or turn it off.

Can I prepare Japanese pork stew ahead?
Yes. You can cook it a day ahead, cool it promptly, and refrigerate it in a covered container. Reheat gently and bring the leftovers to 165°F (74°C). If making it ahead, keep the rice separate. The potatoes may absorb some broth as they sit, so add a small splash of water or dashi during reheating to restore a spoonable consistency.

Can I make the recipe with pork belly or pork loin?
Both work, with a different result. Pork belly makes a richer, more indulgent broth and may need less added oil; skim excess fat if you prefer a lighter surface. Pork loin is lean, so avoid cooking it longer than necessary. Whichever cut you use, check the thickest piece with a thermometer and allow the required 3-minute rest after it reaches 145°F (63°C).
