Japanese Beef and Potato Stew (Nikujaga) Recipe Guide

Japanese beef and potato stew, known as nikujaga, is a home-style simmer of tender beef, potatoes, onion, and often carrot in a savory-sweet broth. Its familiar balance of soy sauce, mirin, and dashi makes it comforting without being heavy, and the ingredients cook together in one pot; families and regions have their own variations.

Ingredients

1 lb (450 g) thinly sliced beef, such as chuck or ribeye, cut into 2-inch (5 cm) pieces
1½ lb (680 g) waxy or all-purpose potatoes, peeled and cut into 1½-inch (4 cm) chunks
1 medium yellow onion, about 8 oz (225 g), cut into thick wedges
1 medium carrot, about 5 oz (150 g), peeled and cut into ½-inch (1 cm) half-moons
6 oz (170 g) shirataki noodles, drained and rinsed (optional)
2 tsp (10 ml) neutral oil, such as canola oil
1½ cups (360 ml) prepared dashi, preferably kombu-and-bonito dashi
¼ cup (60 ml) Japanese soy sauce
2 tbsp (30 ml) mirin
2 tbsp (30 ml) sake
1 tbsp (12 g) granulated sugar
2 tbsp (6 g) thinly sliced scallion greens, for serving (optional)

Instructions

Prepare the ingredients. Cut the potatoes into similarly sized chunks so they soften at about the same rate. Rinse them briefly under cold water to remove loose surface starch, then drain well. Cut the onion and carrot, and separate the beef slices so they are easy to add to the pot. If using shirataki, rinse it thoroughly and cut the strands into manageable lengths. Have the dashi and seasonings measured before you begin cooking.
Brown the beef lightly. Heat the oil in a heavy 4-quart (3.8 L) pot or Dutch oven over medium heat. Add the beef in two batches if necessary and cook for about 3 minutes, turning and separating the slices. Avoid crowding the pan, which makes the beef release liquid and steam rather than take on light color. Check a thick folded piece with a food thermometer; USDA FSIS gives whole cuts of beef a safe minimum internal temperature of 145°F (63°C) with a 3-minute rest. Set the beef on a clean plate to rest while you cook the vegetables. Thin slices can be hard to measure, so check the thickest folded piece, not a loose edge.
Soften the onion and vegetables. Add the onion to the same pot and stir for about 2 minutes, scraping up browned bits. Add the potatoes and carrot and cook for another 2 minutes, turning the pieces gently in the oil. This brief sauté helps coat the vegetables with flavor; it is not meant to cook them through. If the bottom looks dry, add a small splash of the measured dashi rather than more oil.
Simmer until the potatoes are nearly tender. Pour in the dashi, soy sauce, mirin, sake, and sugar. Stir once to distribute the seasoning, then add the shirataki if using. Bring the liquid just to a boil, skim any foam from the surface, and reduce the heat to maintain a gentle simmer. Partially cover the pot and cook for 21 minutes, turning the vegetables carefully once or twice. A vigorous boil can break the potatoes apart and make the broth cloudy. The potatoes should be nearly tender when pierced with a thin knife, with a little resistance at the center.
Finish the stew. Return the rested beef and any juices on the plate to the pot. Simmer gently for 7 minutes, uncovered, until the potatoes are tender and the beef is cooked through. Check a thick piece of beef again with a thermometer and make sure it reaches at least 145°F (63°C); the required 3-minute rest has already taken place while the vegetables simmered. If the slices were too thin to measure reliably, keep them in the bubbling broth until fully cooked. Taste the broth. Add a small splash of soy sauce if it needs more savoriness, or a little water if it tastes too concentrated.
Rest briefly and serve. Turn off the heat and let the stew stand for 2 minutes so the broth settles and the vegetables take up some of its flavor. Ladle into shallow bowls, making sure each serving gets beef, potatoes, onion, carrot, and some broth. Scatter scallion greens over the top if desired.

Tips

Choose potatoes that hold their shape. Yukon Golds or other all-purpose potatoes turn creamy while generally staying intact. Waxy potatoes are firmer and especially useful if you plan to reheat the stew. Very starchy potatoes can become crumbly; cut them generously and handle them gently when stirring.
Use prepared dashi for the classic flavor. Kombu-and-bonito dashi gives the broth a delicate savory depth. If it is hard to find, use dashi powder prepared according to its package directions, or use low-sodium chicken or vegetable broth. Broth makes a pleasant stew but changes its flavor; choose a mild one and taste before adding extra soy sauce.
Balance the seasoning at the end. Soy sauce brands vary in saltiness, and the broth reduces slightly as it simmers. Taste before serving rather than adding more soy automatically. If the stew is too salty, dilute it with a few tablespoons of water or unsalted dashi; if it seems flat, add soy sauce a teaspoon at a time.
Keep the simmer gentle. A low, steady bubble cooks the potatoes evenly. Stir by nudging the vegetables with a spoon instead of vigorously mixing them. If the pot is shallow or the liquid does not reach the vegetables, rotate the pieces during cooking and keep the lid partially on to limit evaporation.

Serving Suggestions

Serve nikujaga hot in individual bowls with steamed Japanese short-grain rice. Rice is a natural partner for the lightly sweet soy-and-dashi broth, and a small bowl lets each person spoon broth over the rice as they eat. A simple side of blanched spinach with sesame, cucumber salad, or quick-pickled daikon adds a fresh, crisp contrast without competing with the stew.

For a fuller Japanese-style meal, offer miso soup and a small vegetable side, keeping their seasonings mild because the stew is already savory. If you are serving it as a one-pot dinner, add extra shirataki or serve a larger portion of rice. Put the scallion garnish on just before serving so it stays bright. The stew is also good at room temperature for a packed meal, but cool and refrigerate it promptly rather than leaving it out for an extended period.

Variations

Make it with pork. Thinly sliced pork shoulder or pork belly is a common alternative to beef in some home versions. Use the same amount and method, cooking it thoroughly in the simmering broth; pork belly will make the liquid richer, while leaner shoulder keeps the result lighter in texture.

Use a meat-free broth and tofu. Replace the beef with 8 oz (225 g) firm tofu, cut into cubes, and use kombu-only dashi or vegetable broth. Brown the tofu gently before adding it back near the end so it does not crumble. This gives a different, milder stew rather than a direct copy of the beef version.

Adjust the sweetness. For a less sweet broth, start with 2 tsp (8 g) sugar instead of 1 tbsp and taste before serving. For a rounder, sweeter style, keep the measured sugar or add up to 1 tsp more. Mirin contributes sweetness as well as aroma, so change the sugar gradually rather than replacing the mirin with extra soy sauce.

Add another vegetable. A small handful of green beans can go in during the final 5 minutes, while sliced mushrooms can be added with the potatoes. Avoid adding watery vegetables too early or in large amounts, since they release liquid and can dilute the seasoned broth.

Storage and Reheating

Cool leftovers and refrigerate them within 2 hours of cooking in a shallow, covered container. Store for 3–4 days in the refrigerator. The potatoes may absorb broth as they sit, so the stew can taste more seasoned the next day; add a splash of water or dashi when reheating if needed. For the best texture, freeze portions for up to 2 months, knowing that thawed potatoes may be softer or slightly grainy. Thaw overnight in the refrigerator.

Reheat a portion in a saucepan over medium-low heat, stirring gently and adding a little water if the broth has thickened. Heat until steaming throughout and 165°F (74°C), checking the center with a food thermometer. In a microwave, cover loosely, heat in short intervals, and stir carefully between intervals so the middle warms evenly; confirm it also reaches 165°F (74°C). Do not repeatedly cool and reheat the same portion.

Frequently Asked Questions

What does nikujaga mean?

Nikujaga is a Japanese name formed from words for meat and potatoes. It describes a family of home-style stews rather than one fixed formula. Beef is widely used, while pork and small changes to the vegetables or seasoning appear in different households and regions.

Can I make Japanese beef and potato stew without dashi?

Yes. Mild chicken broth or vegetable broth works if prepared dashi is unavailable, although the stew will lose some of dashi’s distinctive savory, sea-and-smoke character. A little dashi powder dissolved in water is another practical option. Check its salt content before seasoning because some instant mixes are already salty.

Why did my potatoes fall apart?

They may have been cut too small, cooked at a rolling boil, or stirred too forcefully. Use chunks around 1½ inches (4 cm), keep the liquid at a gentle simmer, and turn the pieces carefully. If a few edges soften into the broth, the stew is still fine; it will simply have a thicker, less clear sauce.

Can I prepare nikujaga ahead?

Yes. It can be made earlier in the day, cooled, and refrigerated, then reheated gently before serving. The vegetables take on more flavor as the stew rests, though they may also become softer. If making it specifically ahead, stop cooking when the potatoes are just tender rather than very soft, and reheat only until the dish reaches 165°F (74°C).

Can I use beef stew cubes instead of thinly sliced beef?

You can, but the texture and cooking time will change. Cubes of chuck need a longer, gentler simmer to become tender, often around 1½ to 2 hours, and the potatoes should be added later so they do not disintegrate. This makes a heartier beef stew inspired by nikujaga rather than the quicker thin-sliced version in this recipe.

What can I use instead of mirin or sake?

If you do not have mirin, use 1 tbsp (15 ml) water mixed with 1 tsp (4 g) sugar for each tablespoon needed; the result will be less aromatic and slightly less rounded. If avoiding sake, replace it with the same amount of water or unsalted broth. These substitutions work, though the broth will have a simpler flavor.
