Japanese Beef Broth Soup with Tofu and Mushrooms

This Japanese-inspired beef broth soup combines tender chunks of beef with daikon, shiitake mushrooms, tofu, and a savory soy-seasoned broth. It is a hearty one-pot meal with familiar Japanese flavors, though home and regional versions vary; serve it hot on its own or with rice.

Ingredients

1½ lb (680 g) boneless beef chuck, cut into 1-inch (2.5 cm) cubes
1 tbsp (15 ml) neutral cooking oil, such as canola
8 cups (1.9 L) low-sodium beef broth
1 piece kombu, about 3 by 4 inches (8 by 10 cm; approximately 4 g)
1 medium yellow onion, about 8 oz (225 g), thinly sliced
1 tbsp (15 g) finely grated fresh ginger
2 tbsp (30 ml) soy sauce, plus more to taste
2 tbsp (30 ml) mirin
1 tbsp (15 ml) sake or dry sherry, optional
1 medium daikon, about 12 oz (340 g), peeled and cut into ½-inch (1.25 cm) half-moons
2 medium carrots, about 6 oz (170 g), peeled and cut into ½-inch (1.25 cm) rounds
6 oz (170 g) shiitake mushrooms, stems removed and caps sliced
1 package firm tofu, 14 oz (397 g), drained and cut into ¾-inch (2 cm) cubes
½ tsp (2.5 g) fine salt, or to taste
¼ tsp (0.5 g) freshly ground black pepper
2 scallions, about 1 oz (30 g), thinly sliced
1 tsp (2 g) toasted sesame seeds, for serving, optional

Instructions

Prepare the ingredients. Pat the beef dry with paper towels so it browns instead of steaming. Cut the onion, daikon, carrots, mushrooms, tofu, and scallions as listed. Keep the tofu chilled until needed. Measure the broth, soy sauce, mirin, and optional sake before you start cooking.
Brown the beef. Heat the oil in a large, heavy pot or Dutch oven over medium-high heat. Add the beef in a single layer, working in batches if the pot is crowded. Brown it for about 8 minutes, turning the pieces so several sides develop color. Transfer the beef to a plate. A little browning on the pot is useful; if the browned bits look black or smell scorched, wipe them out before continuing.
Start the broth. Reduce the heat to medium. Add the onion and ginger and cook for 2 minutes, stirring, until the onion begins to soften. Pour in the beef broth and scrape the browned bits from the bottom of the pot. Add the kombu, soy sauce, mirin, and sake if using, then return the beef and any juices on the plate to the pot.
Simmer until the beef is tender. Bring the liquid just to a boil, then immediately lower the heat so it barely simmers. Cover the pot with the lid slightly ajar and cook for 70 minutes, stirring once or twice. Avoid a hard boil, which can make the meat fibers tighten and leave the broth cloudy. The beef should be starting to soften; if it is still quite firm, give it another 10 minutes before adding the vegetables.
Add the root vegetables. Remove the kombu and discard it; it has already flavored the broth. Stir in the daikon and carrots. Keep the soup at a gentle simmer for 18 minutes, or until both vegetables are easily pierced with a knife but still hold their shape. Check that there is enough liquid to keep the ingredients mostly submerged; add up to 1 cup (240 ml) hot water if needed.
Finish with mushrooms and tofu. Add the shiitake mushrooms and tofu, folding them in gently so the tofu cubes stay intact. Simmer for 9 minutes. Check the center of the largest beef cube with a food thermometer: USDA FSIS lists 145°F (63°C) with a 3-minute rest as the safe minimum for whole cuts of beef. Lift the beef pieces out briefly and let them rest on a clean plate for 3 minutes, then return them to the soup.
Season and serve. Taste the broth and add the salt and pepper, then adjust with a little more soy sauce if it needs depth. Ladle the soup into warm bowls, distributing beef, vegetables, tofu, and mushrooms evenly. Top with scallions and sesame seeds if desired, and serve while steaming hot.

Tips

Choose a cut suited to a gentle braise. Chuck has enough connective tissue to become tender during the simmer. Lean round steak can be used, but it is easier to overcook and may remain less silky. Cut the pieces close to the same size so they cook at a similar rate.
Keep the simmer low. A few small bubbles are enough. A rolling boil can break up the tofu, cloud the broth, and make the beef tougher before its connective tissue softens. If the pot is bubbling vigorously, lower the heat and partially cover it.
Adjust salt at the end. Beef broth and soy sauce vary in saltiness, and the broth reduces slightly as it cooks. Starting with low-sodium broth gives you room to season the finished soup without making it too salty.
Use a practical mirin substitute if needed. For each tablespoon of mirin, mix 1 tablespoon (15 ml) water with ½ teaspoon (2 g) sugar. The substitute provides a little sweetness but lacks mirin’s distinctive aroma, so the broth will taste simpler. Kombu can be omitted if unavailable; the soup will still be savory, with less of its gentle seaweed-like depth.

Serving Suggestions

Serve this soup in deep bowls so each portion gets a good balance of broth, meat, and vegetables. A bowl of steamed Japanese short-grain rice is a natural accompaniment: spoon a little broth over the rice or enjoy it separately between mouthfuls. If you want a more filling meal, serve udon or cooked soba in a separate bowl and ladle the soup over it just before eating. Keeping noodles separate prevents them from soaking up too much broth as they sit.

For a simple table, add pickled vegetables, sliced cucumber, or a small green salad dressed with rice vinegar. Offer extra soy sauce, sliced scallions, and shichimi togarashi at the table so diners can season their own bowls. The soup is substantial enough to serve as the main course, so side dishes can stay light.

Variations

Add noodles: Cook about 8 oz (225 g) dried udon according to its package directions, drain, and divide among bowls. Pour the hot soup over the noodles rather than simmering them in the pot. Fresh or frozen udon also works; cook it separately according to the package, since cooking times differ.

Make it more like a vegetable-forward stew: Add 1 cup (100 g) sliced napa cabbage with the mushrooms. It wilts quickly and contributes a mild sweetness. For extra texture, include 4 oz (115 g) sliced fresh or rehydrated wood ear mushrooms, but drain rehydrated mushrooms well before adding them.

Use a dashi-style base: If you have Japanese dashi, replace 2 cups (480 ml) of the beef broth with dashi. This makes the seaweed and savory notes more noticeable while keeping the soup beefy. For a stronger broth, use 1 tablespoon (15 ml) white miso stirred into a small bowl of hot broth at the end; do not boil the soup after adding miso, as boiling can dull its aroma.

Make it spicy: Add a small amount of chili oil or shichimi togarashi to each bowl. Adding spice at the table lets you keep the main pot mild, which is useful when serving people with different heat preferences. A few drops of toasted sesame oil also work, but use a light hand so it does not overwhelm the broth.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking. Cool the soup in shallow containers for faster chilling, then cover and refrigerate for 3 to 4 days. The broth may turn slightly cloudy or set into a soft gel when cold; that is normal for broth containing beef gelatin. Tofu can become a little firmer and absorb some broth over time, but the soup remains suitable to reheat within the recommended window.

For longer storage, freeze the soup in airtight, freezer-safe containers for up to 2 months for best quality. Leave a little room at the top for expansion. Thaw it overnight in the refrigerator, or reheat it from frozen over low heat with a splash of water. The daikon and tofu may soften after freezing, so if texture matters, freeze the beef and broth separately from freshly prepared tofu and vegetables.

Reheat only the portion you plan to eat in a covered saucepan over medium-low heat, stirring gently until evenly hot. A food thermometer should read 165°F (74°C) for leftovers, following USDA FSIS guidance. Avoid boiling hard, which can crumble tofu and make the vegetables mushy. Add a spoonful of water or broth if the soup has reduced in storage, then taste and adjust the seasoning before serving.

Frequently Asked Questions

Is Japanese beef broth soup a traditional Japanese dish?
This recipe is Japanese-inspired rather than a claim to one definitive traditional soup. Japanese home cooking includes many regional and household variations of simmered soups, and beef broth is not the base for every Japanese soup. Here, soy, mirin, kombu, ginger, and scallions give a beef-and-vegetable soup a Japanese flavor profile.

Can I use store-bought beef broth?
Yes. Choose a low-sodium broth so you can control the final salt level. If your broth is already strongly seasoned, reduce the soy sauce to 1 tablespoon (15 ml) at first and add more only after the vegetables and tofu have cooked.

Can I make this soup without kombu?
Yes. Simply leave it out; the beef broth, soy sauce, mushrooms, and ginger still make a flavorful soup. If you have instant dashi granules, you can add a small amount according to the package directions, but taste before adding extra salt because many granules are seasoned.

Why is my beef still tough after simmering?
Chuck needs gentle heat and enough time for its connective tissue to soften. Check that the soup is barely simmering, not boiling, and continue cooking the beef in 10-minute increments until tender before adding the vegetables. If the broth has reduced too much, add hot water to keep the beef surrounded by liquid.

Can I prepare it ahead?
Yes. Cook the soup a day ahead, cool it promptly, and refrigerate it in a covered container. The flavors mingle as it rests, though the tofu may absorb more broth. Reheat gently to 165°F (74°C), then add fresh scallions and any optional noodles just before serving.

What can I use instead of daikon?
Use an equal weight of turnip for a similar mild, slightly peppery character, or use peeled parsnip for a sweeter result. Cut the substitute into pieces of similar thickness and start checking tenderness around the 15-minute mark, since different vegetables soften at different rates.
