Oden Japanese Stew: How to Make a Dashi-Rich Pot

Oden is a Japanese one-pot stew of daikon, boiled eggs, konnyaku, and assorted fish cakes gently simmered in a light, savory dashi broth. This home-style version builds the broth from kombu and bonito flakes, then gives the ingredients time to take on its flavor; families and regions vary the mix-ins, so use the list as a satisfying starting point rather than a fixed rule.

Ingredients

6 cups (1.4 L) water
1 piece dried kombu, about 4 inches (10 g)
½ cup (15 g) loosely packed katsuobushi, or dried bonito flakes
1 pound (450 g) daikon radish, peeled and cut into four 1-inch (2.5 cm) thick rounds
4 large eggs
1 block (9 ounces/250 g) konnyaku, drained
4 chikuwa fish cakes, about 6 ounces (170 g) total
4 satsuma-age fish cakes, about 6 ounces (170 g) total
1 block atsuage, about 7 ounces (200 g), cut into four pieces
¼ cup (60 ml) Japanese soy sauce
¼ cup (60 ml) mirin
2 tablespoons (30 ml) sake, optional
Karashi Japanese mustard, about 2 teaspoons (10 g), for serving

Instructions

Prepare the ingredients. Peel the daikon and cut it into thick rounds. Drain the konnyaku, rinse it, and cut it into bite-size triangles or rectangles; lightly score each piece in a shallow crosshatch so broth can reach the surface. Cut the atsuage into four portions. Set out the fish cakes and seasonings. Allow about 25 minutes for these hands-on tasks, including peeling the cooked eggs later in the process.
Cook and peel the eggs. Put the eggs in a saucepan and cover them with water. Bring the water to a boil, then boil the eggs for 10 minutes. Transfer them to cold water until cool enough to handle, then peel. For whole boiled eggs, cook until both the yolk and white are firm. Set aside; they will warm through in the stew.
Parboil the daikon. Put the daikon rounds in a saucepan, cover with fresh water, bring to a boil, and simmer for 15 minutes. Drain. This preliminary cooking softens the centers and reduces the radish’s sharp edge, so it can absorb the seasoned broth evenly. A skewer should begin to enter the rounds, though they do not need to be completely tender yet.
Blanch the konnyaku. Bring a small saucepan of water to a boil, add the konnyaku, and boil for 5 minutes. Drain well. This quick blanch helps mellow its aroma. If the package gives different preparation instructions, follow those directions; some ready-to-use varieties need only rinsing.
Make the dashi. Add the 6 cups water and kombu to a pot large enough to hold all the ingredients. Warm over medium-low heat until the water is steaming and small bubbles gather around the edge, about 10 minutes; do not let the kombu boil vigorously. Remove the kombu, turn off the heat, and stir in the bonito flakes. Steep for 5 minutes, then strain the broth through a fine sieve. You should have roughly 5 cups (1.2 L) of dashi.
Season and simmer the daikon. Return the strained dashi to the pot. Stir in the soy sauce, mirin, and sake, if using. Add the parboiled daikon and bring the broth just to a gentle simmer. Partly cover the pot and simmer gently for 40 minutes, turning the rounds once if they are not mostly submerged. Keep the liquid below a rolling boil; vigorous bubbling can break up the fish cakes later and make the broth taste harsher.
Add the remaining ingredients. Nestle in the eggs, konnyaku, chikuwa, satsuma-age, and atsuage. Keep the broth at a gentle simmer for 15 minutes, turning the pieces once if needed so they heat evenly. Check one of the thickest fish-cake pieces with a food thermometer: because these are seafood products being heated in the stew, USDA FSIS guidance calls for fish to reach a safe minimum internal temperature of 145°F (63°C). If a piece has not reached that temperature, continue simmering and check again. The eggs should remain whole, and the broth should barely bubble.
Rest before serving. Turn off the heat and leave the covered pot to stand for 15 minutes. This final wait gives the daikon and other pieces a chance to take up more broth flavor. Taste the broth; if it seems too salty, add a little hot water, or if it tastes mild, offer soy sauce at the table rather than reducing the broth aggressively.

Tips

Keep the simmer calm. Oden is gently braised, not rapidly boiled. A low simmer helps the daikon stay intact and keeps delicate fish cakes from splitting. If the surface is bubbling hard, lower the heat or briefly move the pot off the burner.
Let pieces sit in the broth. Oden often tastes even more settled after a rest, and the daikon benefits especially. If you have time, make it earlier in the day, cool it promptly, refrigerate it, and reheat it gently for dinner. Do not leave the pot at room temperature for an extended period.
Choose fish cakes that are easy to find. Chikuwa and satsuma-age are available in many Japanese or Asian grocery stores. If satsuma-age is unavailable, use another cooked Japanese fish cake or fish balls; the exact texture and seasoning will change, but the dish will still work. Avoid adding raw seafood unless you adjust the cooking and temperature checks accordingly.
Adjust the broth thoughtfully. Japanese soy sauces and fish cakes differ in saltiness, so taste before adding extra soy sauce. If you cannot find mirin, use 3 tablespoons (45 ml) water mixed with 1 tablespoon (15 ml) sugar in its place; the broth will lack mirin’s gentle rice-wine aroma but will retain some sweetness.

Serving Suggestions

Serve oden hot in individual bowls, making sure each person gets a little broth and a mix of vegetables, egg, and fish cakes. Set out karashi mustard for dipping or stirring into a bite; it is sharp and pungent, so a small dab is usually enough. In Japan, oden may be a casual meal or a shared dish alongside other small plates, and the exact accompaniments vary by household.

For a fuller meal, offer steamed Japanese rice, which is useful for balancing the salty-savory broth, plus a simple cucumber salad or lightly dressed greens. You can also serve the pot as the main event with extra broth ladled over the ingredients. Provide spoons as well as chopsticks: the daikon and egg are easy to eat with chopsticks, while a spoon makes it easier to enjoy the dashi.

Variations

Use a different dashi. For a vegetarian broth, replace the bonito flakes with 3 dried shiitake mushrooms (about 15 g), soaked in the 6 cups (1.4 L) water until softened; strain the liquid and remove the mushroom stems. This gives a deeper, earthier flavor and omits the bonito’s clean, savory note. Kombu dashi alone is another option, with a lighter taste. Check the labels on fish cakes and atsuage if you need to avoid fish, since many traditional versions contain seafood.

Change the mix-ins. Add peeled boiled potatoes, extra daikon, or other cooked fish cakes, keeping the total amount manageable so everything can sit in the broth. Some versions include beef tendon or different regional fish cakes; those ingredients are not included here, and their cooking times vary. If you add meat, cook it safely and separately as needed before adding it to the pot, rather than assuming a short final simmer will cook raw meat through.

Make it milder or more robust. Use less soy sauce at first and pass extra at the table for a gentler broth. For a stronger dashi flavor, add another small piece of kombu while warming the water, removing it before the liquid boils. Avoid simmering kombu hard, which can make the broth slick or bitter.

Storage and Reheating

Refrigerate leftover oden within 2 hours of cooking, ideally in a shallow covered container with enough broth to keep the ingredients from drying out. Keep it refrigerated for 3–4 days. The daikon and eggs generally hold their shape well, while fish cakes may soften slightly as they sit. If possible, store the broth and solids together so the pieces stay moist.

Reheat only the portion you plan to eat in a saucepan over medium-low heat, stirring carefully and turning the larger pieces so they warm through. USDA FSIS recommends reheating leftovers to 165°F (74°C); check the center of a thick piece with a food thermometer. Avoid a prolonged rolling boil, which can make the fish cakes spongy and break apart the daikon. Freezing is possible, but konnyaku and some fish cakes can become rubbery or watery after thawing, so the texture will be less appealing than freshly made.

Frequently Asked Questions

What is oden made of?
Oden is a Japanese stew of assorted ingredients simmered in a lightly seasoned dashi broth. Daikon, boiled eggs, konnyaku, and cooked fish cakes are common choices, but the combination varies by region, season, and household. This recipe uses those familiar ingredients without suggesting there is one required lineup.

What is konnyaku, and can I leave it out?
Konnyaku is a firm, springy food made from konjac yam starch. It is sold in blocks in many Japanese and Asian grocery stores, often near tofu or refrigerated noodles. You can omit it if you cannot find it; add extra daikon or another cooked fish cake instead. The stew will lose konnyaku’s distinctive chewy texture, but the broth does not need a special adjustment.

Can I use instant dashi?
Yes. Prepare enough instant dashi to make about 5 cups (1.2 L), following the package directions, then season it with the soy sauce, mirin, and optional sake in this recipe. Instant dashi is convenient, though its flavor and salt level vary by product. Taste the broth before adding any extra seasoning.

Can I make oden ahead?
Yes. Make it earlier the same day, cool and refrigerate it within 2 hours, then reheat it gently before serving. The ingredients can absorb more broth flavor as they rest, but the stew still needs safe refrigeration. Reheat leftovers to 165°F (74°C), measured with a food thermometer.

Why is my daikon still firm?
Daikon size and age affect how quickly it softens. Cut particularly thick rounds in half or continue the gentle simmer until a skewer passes through the center with little resistance. Keep the broth from boiling hard, and allow the covered pot to rest as directed; a short rest improves flavor but will not make a very firm center tender on its own.
