Swedish Icebreaker Oden: Dill and Root Veg

“Swedish icebreaker oden” is not a documented traditional Swedish dish: Oden is the name of a Swedish icebreaker, while oden is a Japanese simmered hot pot. This recipe is a clearly labeled Swedish-inspired take on Japanese oden, with daikon, potatoes, fish cakes, dill, and mustard in a savory broth; it is warming, easy to adapt, and served in bowls with plenty of broth.

Ingredients

8 cups (1.9 L) cold water
1 piece dried kombu, about 4 by 4 inches (10 by 10 cm; about 8 g)
1 cup (10 g) loosely packed dried bonito flakes (katsuobushi)
1 medium daikon radish, about 12 oz (340 g), peeled
1 lb (450 g) waxy potatoes, such as Yukon Gold, scrubbed and cut into large bite-size pieces
2 medium carrots, about 5 oz (150 g), peeled and cut into thick diagonal slices
4 large eggs (about 200 g without shells)
7 oz (200 g) prepared konnyaku, cut into bite-size triangles, optional
12 oz (340 g) fully cooked Japanese fish cakes, such as chikuwa, satsuma-age, or a mix, cut into serving-size pieces
8 oz (225 g) firm tofu, drained and cut into 4 pieces
3 tbsp (45 ml) Japanese soy sauce
2 tbsp (30 ml) mirin
1 tsp (5 g) fine salt, plus more to taste
2 tbsp (6 g) chopped fresh dill, plus extra to serve
2 tbsp (30 g) Swedish-style coarse mustard, for serving
4 slices (about 160 g) rye bread, for serving

Instructions

Start the broth. Put the cold water and kombu in a large pot. Leave it to steep for 20 minutes while you prepare the vegetables. Keep the kombu in the water as you warm it over medium heat. Just before the water reaches a boil, remove and discard the kombu; boiling it can make the broth slimy or bitter. Add the bonito flakes, turn off the heat, and steep for 5 minutes. Strain the broth through a fine sieve into a bowl, then return it to the pot. If you do not have a sieve, lift out the flakes with a slotted spoon, though the broth may be less clear.
Prepare the vegetables and konnyaku. Cut the daikon into 1-inch (2.5 cm) rounds or half-rounds, depending on its width. Cut an X about ¼ inch (6 mm) deep into one side of each piece; this helps the broth season the center. If you have time, briefly parboil the daikon in a separate pan of water for 8 to 10 minutes, then drain it. This optional step softens its sharper flavor and helps it cook evenly. For konnyaku, rinse it and follow the package directions; if directed, parboil it for a few minutes to mellow its aroma. Drain before adding it to the pot.
Cook the eggs. Place the eggs in a saucepan and cover with cold water. Bring to a boil, then lower the heat to maintain a gentle boil for 10 to 12 minutes. Transfer them to cold water until cool enough to handle, peel, and set aside. Whole eggs are ready when the yolks and whites are firm. Add them peeled so the broth can season the outside.
Season and simmer the root vegetables. Stir the soy sauce, mirin, and salt into the strained broth. Add the daikon, potatoes, carrots, and konnyaku, if using. Bring the pot to a gentle simmer, not a hard boil, and cook uncovered for about 25 minutes. Check the largest pieces with a thin knife: the knife should slide into the daikon and potatoes with little resistance, but the pieces should still hold their shape. If the potatoes are smaller or softer, check them sooner and lift them out temporarily if they are done before the daikon.
Add the remaining ingredients. Gently lower in the peeled eggs, fish cakes, and tofu. Keep the broth at a quiet simmer for 15 minutes, turning the eggs once if they are not mostly submerged. Avoid vigorous stirring, which can break the tofu and fish cakes. Taste the broth and add a little more salt or soy sauce if needed. Fold in the chopped dill during the last minute so it stays fresh and fragrant.
Serve hot. Divide the vegetables, eggs, fish cakes, tofu, and konnyaku among four deep bowls. Ladle broth over each serving, add a small spoonful of coarse mustard and a pinch of dill, and serve with rye bread. Put any extra mustard at the table so each person can adjust the sharpness.

Tips

Keep the broth below a rolling boil. A gentle simmer helps the pieces stay intact and gives the broth time to season them. If the liquid bubbles vigorously, lower the heat; top up with a little hot water if evaporation leaves the ingredients exposed.
Use a practical dashi substitute if needed. Kombu and bonito flakes are sold in Japanese grocery stores and many larger supermarkets. If you cannot find them, use 8 cups (1.9 L) prepared dashi or a broth made with dashi granules according to the package. A light vegetable broth works too, though it will be less distinctly Japanese and have less savory depth. Do not use Swedish fish stock unless you want a stronger, more pronounced seafood flavor.
Choose the right potatoes and fish cakes. Waxy potatoes hold together better than very floury baking potatoes. Japanese fish cakes are often sold frozen or refrigerated; use fully cooked products and thaw frozen pieces in the refrigerator before adding them. If they are unavailable, use cooked, mild white fish balls or omit them and add extra tofu.
Season gradually. Soy sauce, fish cakes, and prepared dashi vary in saltiness. Begin with the listed salt, taste after simmering, and adjust at the end. The mustard is meant to be a bright condiment, not stirred into the whole pot.

Serving Suggestions

Serve the pot as the center of a relaxed meal: set the hot ingredients and broth on the table, then let everyone choose a mix for a deep bowl. Rye bread is the Swedish-leaning accompaniment here; its earthy, slightly tangy flavor is satisfying alongside the delicate dashi. If you prefer a more Japanese-style table, offer plain rice instead. A crisp cucumber salad or lightly dressed cabbage adds a fresh contrast without competing with the broth.

Put coarse mustard and extra dill in separate small dishes. A small dab of mustard gives a punchy, savory edge, while dill makes the bowl smell distinctly Scandinavian. Start with less than you think you need, particularly if your mustard is strong. Serve the hot pot as soon as the tofu and fish cakes are warmed through, and provide spoons as well as chopsticks so the broth is easy to enjoy.

Variations

Make it vegetarian. Leave out the bonito flakes and use kombu dashi or a mild vegetable broth. Replace the fish cakes with extra firm tofu, thick slices of seitan, or cooked mushrooms. Konnyaku is already plant-based, but check its package if you are cooking for someone with strict dietary requirements. The vegetarian broth will taste lighter; a teaspoon of white miso stirred in off the heat can add savoriness, though it changes the flavor and makes the dish less like classic oden.

Lean further into Swedish flavors. Use a little more dill at the table and serve with rye bread and coarse mustard. You can replace some of the potatoes with 1 cup (130 g) of peeled, cubed rutabaga, adding it with the other root vegetables. Rutabaga brings a mild sweetness and a firmer bite. Keep the soy and dashi base, however, if you want the result to remain recognizably oden-inspired rather than becoming a conventional Swedish soup.

Adjust the fish cakes. A mix of chikuwa and fried satsuma-age gives different textures, but any mild, fully cooked Japanese fish cake is suitable. For a simpler grocery-store version, use cooked fish balls or omit the fish cakes and add another 8 oz (225 g) tofu. Avoid raw fish in this recipe unless you are prepared to cook it separately to a safe temperature; the listed timing is for ready-to-eat fish cakes.

Make it milder or richer. For a gentler broth, reduce the soy sauce to 2 tablespoons (30 ml) and add more only after tasting. For a richer bowl, add 4 oz (115 g) sliced shiitake mushrooms with the root vegetables. Their flavor will deepen the broth, so taste before adding extra salt. These adjustments are flexible, but keep the pot at a simmer so the ingredients do not fall apart.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in a covered container. For best texture, store the broth and solid ingredients together so the vegetables stay moist, or keep the tofu separate if you prefer it firmer. Refrigerated oden keeps for 3 to 4 days. The potatoes may soften and absorb more broth as they sit, and the flavors will become saltier and more concentrated, so taste before serving again.

Reheat only the portion you plan to eat in a saucepan over medium-low heat until steaming throughout, stirring gently. USDA FSIS recommends reheating leftovers to 165°F (74°C); check the center of a large piece with a food thermometer. Add a splash of water if the broth has become too concentrated. You can freeze the broth and sturdy vegetables for up to 2 months for best quality, but potatoes, tofu, and fish cakes may become softer or spongier after thawing. Thaw overnight in the refrigerator and reheat to 165°F (74°C).

Frequently Asked Questions

Is Swedish icebreaker oden a traditional Swedish recipe?
No established traditional dish by that name is documented here. Oden is a Japanese simmered hot pot, and Oden is also the name of a Swedish icebreaker. This recipe combines Japanese oden-style ingredients with Swedish cues such as dill, mustard, root vegetables, and rye bread; it is a modern fusion idea, not a historical Swedish recipe.

What does oden usually contain?
Oden commonly includes ingredients such as daikon, boiled eggs, tofu, konnyaku, and assorted fish cakes simmered in a seasoned dashi broth. The exact assortment varies by region, shop, season, and household. This version keeps that simmered-hot-pot format while adding potatoes, carrots, dill, and mustard for its Swedish-inspired character.

Can I make the broth without bonito flakes?
Yes. Use kombu-only broth or a mild vegetable broth for a vegetarian option, or use prepared dashi if you have it. Bonito adds a savory, lightly smoky note, so the broth will taste gentler without it. Taste at the end and adjust the salt and soy sauce rather than trying to replace the flakes with a large amount of soy sauce.

Do I have to use konnyaku?
No. It contributes a springy, pleasantly chewy texture, but the hot pot works without it. Look for it in Japanese or other East Asian grocery stores, often packaged in water. If you cannot find it, use extra tofu or mushrooms, or simply leave it out; do not substitute an equal weight of another ingredient unless you want a fuller pot.

Can I prepare oden ahead?
Yes. You can make the broth and cook the root vegetables a day ahead, then refrigerate them promptly. Reheat the broth and vegetables gently, add the cooked fish cakes and tofu, and simmer until hot. Add fresh dill when serving. The vegetables absorb broth as they rest, so keep a little extra water or unsalted broth available to loosen the pot if needed.

What if I cannot find Japanese fish cakes?
Use cooked fish balls or extra firm tofu, or leave the fish cakes out. Japanese fish cakes have a distinct springy texture and mild seafood flavor, so substitutes will change the character of the bowl. Check labels for allergens, especially fish, egg, soy, and wheat, since ingredients vary by product.
