Japanese Oxtail Stew with Daikon, Ginger, and Soy Sauce

Japanese-style oxtail stew braises beef tails until tender in a savory broth of soy sauce, sake, mirin, and ginger, with daikon and carrots added near the end. It is a slow, comforting stovetop dish served with rice; Japanese home-style braises vary, and this version balances rich beef with a gently sweet, salty broth.

The long simmer does the important work: it softens the connective tissue in oxtail and gives the broth time to take on ginger and beef flavor. Blanching the tails first helps keep that broth clearer and cleaner-tasting, while adding the vegetables later lets them become tender without falling apart.

Ingredients

3½ lb (1.6 kg) bone-in oxtail, cut into pieces
12 cups (2.8 L) cold water, for blanching the oxtail
8 cups (1.9 L) unsalted dashi or unsalted beef stock, plus a little more if needed
½ cup (120 ml) Japanese soy sauce, preferably reduced-sodium
½ cup (120 ml) sake
⅓ cup (80 ml) mirin
2 tbsp (25 g) granulated sugar
2 oz (55 g) fresh ginger, scrubbed and sliced into coins
4 garlic cloves (about 12 g), lightly crushed and peeled
1 lb (450 g) daikon, peeled and cut into 1½-inch (4 cm) chunks
2 medium carrots (about 300 g), peeled and cut into thick diagonal pieces
3 scallions (about 45 g), thinly sliced, for serving
1 tsp (2 g) toasted sesame seeds, for serving, optional

Instructions

Prepare the oxtail and vegetables. Pat the oxtail dry and trim away any large, hard pieces of surface fat, leaving the meat and the smaller seams of fat in place. Peel and cut the daikon and carrots, slice the ginger, and crush the garlic. The vegetables can wait on a plate while the beef cooks; keeping the daikon pieces fairly large helps them hold their shape during the final simmer.
Blanch the oxtail. Put the oxtail in a large pot and cover with the 12 cups (2.8 L) cold water. Bring it to a boil over medium-high heat and boil for 10 minutes. Foam and residue will rise to the surface. Drain the pieces in a colander, discard the blanching water, and rinse the pot and the oxtail under cool running water. Rinsing away the foam is worthwhile: it reduces impurities that can make the finished broth cloudy or slightly bitter. Take care around the hot water and use tongs to handle the pieces.
Brown the meat. Dry the rinsed pieces thoroughly with paper towels. Set the cleaned pot over medium-high heat and brown the oxtail in batches, turning the pieces so several sides develop color, about 15 minutes total. Avoid crowding the pot; crowded meat steams instead of browning. If the pot becomes very dry, add a teaspoon of neutral oil, though the oxtail will usually release some fat as it heats. Pour off excess rendered fat, leaving any browned bits stuck to the bottom.
Start the braise. Return all the oxtail to the pot. Add the dashi or stock, soy sauce, sake, mirin, sugar, ginger, and garlic. The liquid should come close to covering the pieces. Add up to 1 cup (240 ml) water if needed, but do not dilute it more than necessary. Bring the liquid just to a boil, skim any foam, then lower the heat to maintain a gentle simmer. Cover with the lid slightly ajar. A quiet simmer with occasional small bubbles is better than a hard boil, which can make the meat fibers tighten and the broth reduce too quickly.
Simmer until the beef is safe and tender. Cook gently for 3 hours and 10 minutes, turning the pieces once or twice and checking that the pot is not boiling dry. Use a food thermometer to check a thick, meaty piece away from the bone: it must reach at least 145°F (63°C), the USDA FSIS safe minimum for whole cuts of beef, followed by a 3-minute rest. If that point is reached before the meat is tender, return the pieces to the pot and continue the covered braise; the tenderness goal is meat that yields readily to a fork. The required temperature is a safety check, while the longer, gentle cook is what makes oxtail pleasantly tender.
Add the vegetables near the end. When about 40 minutes remain in the simmer, add the daikon and carrots. Turn them carefully so they are mostly submerged, cover the pot again, and keep the broth at a gentle simmer. They should be fork-tender but still hold their shape. If the liquid level drops below the vegetables, add a splash of hot water or stock rather than cold water, which can interrupt the simmer.
Finish and serve. Turn off the heat and taste the broth. If it needs more savoriness, add soy sauce 1 teaspoon (5 ml) at a time; if it is too concentrated, loosen it with a little hot water. Spoon away excess surface fat if desired. Serve the oxtail and vegetables with plenty of broth, scattering scallions and sesame seeds over the top. Keep a small bowl nearby for the bones.

Tips

Choose the right liquid. Unsalted dashi gives the stew a lighter, more distinctly Japanese savory note. Unsalted beef stock makes it fuller and more beef-forward. If using salted stock, choose reduced-sodium soy sauce and taste before adding any extra salt; the broth reduces as it cooks.
Substitute for mirin thoughtfully. Mirin is sweet rice wine and contributes both sweetness and a rounded aroma. If it is unavailable, use ¼ cup (60 ml) sake or water mixed with 1 tablespoon (12 g) sugar in place of the ⅓ cup (80 ml) mirin. The flavor will be less fragrant and slightly less sweet, so adjust only after tasting.
Keep the simmer gentle. A rolling boil can break up the daikon, reduce the liquid unevenly, and make the beef less tender. If the surface is bubbling vigorously, lower the heat. Check the pot periodically, especially during the last hour, and top up with hot water if necessary.
Let the broth settle if you have time. The stew tastes good freshly made, but a short rest gives the broth a chance to settle and makes excess fat easier to remove. For a more complete fat-removal step, chill the cooked stew safely and lift off the firm fat the next day before reheating.

Serving Suggestions

Serve the stew hot in deep bowls with steamed Japanese short-grain rice. The rice is useful for soaking up the salty-sweet broth, while the oxtail and vegetables make the bowl substantial. For a lighter meal, serve a smaller portion alongside plain rice and a crisp vegetable side, such as cucumber dressed with rice vinegar, or simply offer sliced scallions and pickled vegetables at the table.

Include a spoon as well as chopsticks: the broth is part of the meal, and the meat may loosen from the bones enough to eat with either. If serving several people, divide the oxtail and vegetables evenly first, then ladle broth into each bowl. A little extra soy sauce can be offered at the table, but taste the stew before adding it because the broth is already seasoned and concentrates as it simmers.

Variations

Add konnyaku: Rinse and briefly boil 7 oz (200 g) konnyaku, then cut it into bite-size pieces and add it with the daikon and carrots. It has a pleasantly springy texture and takes on the broth’s flavor, though it does not add much of its own. Follow the package directions if the product requires preparation before cooking.

Make it with kombu dashi: Use unsalted kombu dashi for a gentler broth. Dried shiitake can also be added for more depth; remove the stems and slice the softened caps before adding them with the vegetables. These additions change the balance toward a more pronounced mushroom-and-seaweed savoriness, so taste before adding more soy sauce.

Adjust the sweetness or heat: For a less sweet, more savory stew, reduce the sugar to 1 tablespoon (12 g). For a little warmth, add 1 small dried red chile (about 1 g) to the braising liquid and remove it before serving. The chile should lend a mild background note, not overwhelm the ginger and soy.

Use a pressure cooker: A pressure cooker can shorten the braising portion, but cooking time varies by appliance and by the size of the oxtail pieces. Follow the manufacturer’s instructions for filling, pressure release, and timing, and check that the meat is fork-tender before serving. Cook the daikon and carrots separately or add them for only a brief final pressure cook so they do not turn mushy.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking. Transfer the stew to shallow, covered containers so it cools more quickly, and keep it refrigerated for 3 to 4 days. The broth may turn gelatinous when cold because of the connective tissue in oxtail; that is normal, and it will liquefy as it warms. If you chill the whole pot, divide the stew into smaller containers first rather than leaving a large, deep pot to cool slowly.

For longer storage, freeze the stew in meal-size airtight containers for up to 3 months for best quality. Leave a little room at the top for expansion. Thaw it overnight in the refrigerator when possible. Reheat gently in a covered saucepan over medium-low heat, stirring carefully so the vegetables do not break apart; add a splash of water or stock if the broth has thickened. Reheat leftovers to 165°F (74°C), checking with a food thermometer, and bring the broth to a steady simmer. Reheat only the portion you plan to eat.

Frequently Asked Questions

Can I make Japanese oxtail stew a day ahead?
Yes. Cool and refrigerate it promptly, then reheat it the next day. The flavors have time to mingle, and chilled fat is easy to lift from the surface. For the best vegetable texture, avoid simmering the stew for a long time again; reheat gently just until the entire portion reaches 165°F (74°C).

Why blanch oxtail before braising?
Blanching briefly brings foam and residue to the surface, and rinsing removes much of it before the seasoned braise begins. It is not a substitute for cooking the meat safely, and it does not remove all fat. The step mainly helps the final broth taste cleaner and look less cloudy.

How can I tell when oxtail is done?
Use both a thermometer and a tenderness check. The thickest meaty part should reach the USDA FSIS safe minimum of 145°F (63°C) with a 3-minute rest for whole beef cuts, and then continue braising until a fork slides into the meat easily. Oxtail pieces differ in size, so some may become tender before others; remove those carefully and keep them warm while the rest finish.

Can I use beef broth instead of dashi?
Yes. Unsalted beef stock is a convenient substitute and makes the stew taste richer and more beef-centered. Dashi has a lighter, more delicate savory character. If you only have salted broth, use reduced-sodium soy sauce and wait until the end to decide whether the stew needs any additional seasoning.

What can I use if I cannot find daikon?
Use 1 lb (450 g) of peeled turnip or rutabaga cut into similarly sized chunks. Turnip has a sharper, earthier flavor, while rutabaga is sweeter and denser; either will make the stew less specifically Japanese in character but still work in the braise. Add the pieces with the carrots and check them with a fork near the end, since their cooking times can vary.
