Ingredients
This recipe makes 4 generous servings.
- For the Soup Base:
- 4 cups (960ml) dashi stock (store-bought or homemade)
- 4-5 tablespoons miso paste (red or a mix of red and white, to taste)
- 1 tablespoon sake (optional, for extra depth)
- 1 tablespoon soy sauce (optional, for seasoning)
- For the Pork & Vegetables:
- 6 ounces (170g) thinly sliced pork belly or pork shoulder (komagire), cut into 1-inch pieces
- 1 tablespoon sesame oil
- 1 small daikon radish (about 6 inches), peeled and cut into 1/2-inch half-moons
- 1 medium carrot, peeled and cut into 1/2-inch rounds or half-moons
- 1 burdock root (gobō), scraped clean and thinly shaved or sliced diagonally (soak in water for 5 minutes)
- 2-3 small satoimo (taro root), peeled and cut into quarters, or 1 small potato, peeled and diced
- 1 block (6 ounces / 170g) konnyaku (konjac yam cake), torn or cut into small, irregular pieces
- 4-5 fresh shiitake mushrooms, stemmed and sliced, or 1/2 cup dried shiitake, rehydrated and sliced
- 1/2 block (7 ounces / 200g) firm tofu or atsuage (fried tofu), cut into 1-inch cubes
- For Garnish:
- 2 green onions, thinly sliced
- Shichimi Togarashi (Japanese seven-spice blend), for serving (optional)
Step-by-Step Instructions
-
Step 1: Prepare the Vegetables
Start by preparing all your vegetables. Peel and slice the daikon radish and carrot. Scrape the burdock root, then thinly shave or slice it diagonally. Immediately soak the burdock in a bowl of water for about 5 minutes to remove bitterness. Peel and quarter the satoimo or dice the potato. Tear the konnyaku into small, irregular pieces. Slice the shiitake mushrooms and cut the tofu into cubes.
Small tip: Tearing konnyaku creates more surface area for the flavors to cling to. -
Step 2: Sauté the Pork and Root Vegetables
Heat the sesame oil in a large pot or Dutch oven over medium heat. Add the thinly sliced pork and cook until it’s no longer pink, breaking it up with your spoon. Add the daikon radish, carrot, burdock root (drained from water), and satoimo (or potato). Sauté for 5-7 minutes, stirring occasionally, until the vegetables start to soften slightly.
Small tip: Sautéing the pork and vegetables first deepens their flavor and adds a wonderful aroma to the soup. -
Step 3: Add Dashi and Simmer
Pour in the dashi stock, sake (if using), and soy sauce (if using). Bring the mixture to a gentle boil, then reduce the heat to low. Cover the pot and simmer for about 15 minutes, or until the root vegetables are tender when pierced with a fork.
Small tip: Ensure the heat is low during simmering to prevent the vegetables from breaking apart and to allow flavors to meld slowly. -
Step 4: Add Remaining Ingredients
Add the konnyaku, shiitake mushrooms, and tofu to the pot. Continue to simmer for another 5-7 minutes, allowing these ingredients to heat through and absorb the delicious dashi flavor.
Small tip: Adding the softer ingredients later prevents them from becoming overcooked or mushy. -
Step 5: Incorporate Miso Paste
Turn off the heat. Ladle a small amount of the hot broth into a separate bowl. Add the miso paste to this bowl and whisk until it’s fully dissolved and smooth. Pour the dissolved miso back into the main pot and stir gently to combine.
Small tip: Never boil miso soup after adding the miso, as it can diminish the miso’s delicate flavor and beneficial probiotics. -
Step 6: Taste and Adjust
Taste the Tonjiru and adjust seasoning if needed. You might want to add a little more miso paste for a stronger flavor, or a dash of soy sauce if it needs more saltiness. Remember, the flavor will deepen slightly as it sits.
Small tip: Always taste before adding more seasoning; it’s easier to add than to remove! -
Step 7: Serve Hot
Ladle the hot Tonjiru into individual serving bowls. Garnish each bowl generously with thinly sliced green onions.
Small tip: Serve immediately to enjoy the freshest flavors and textures. -
Step 8: Add Optional Garnish
For an extra kick, offer Shichimi Togarashi on the side for those who enjoy a little spice. This seven-spice blend adds a wonderful aroma and gentle heat.
Small tip: A sprinkle of shichimi togarashi can elevate the flavor profile without overpowering the dish.
Tips & Variations
- Gluten-Free Option: Ensure your miso paste is certified gluten-free (some contain barley). Use tamari instead of regular soy sauce, or omit soy sauce entirely.
- Vegan/Vegetarian Option: Omit the pork. Replace dashi with a kombu (kelp) or mushroom-based vegetarian dashi. You can add extra mushrooms, more tofu, or even some robust root vegetables like sweet potato or kabocha squash for heartiness.
- Add More Vegetables or Protein: Feel free to add other seasonal vegetables like napa cabbage, spinach (stir in at the very end), enoki mushrooms, or even thinly sliced chicken for a different protein.
- Spicy Version: Stir in a teaspoon of gochujang (Korean chili paste) or a pinch of red pepper flakes along with the miso paste. A dash of rayu (Japanese chili oil) at serving is also delicious.
- Creamier Tonjiru: For a slightly richer, creamier soup, you can add a splash of milk or unsweetened soy milk at the very end, just before serving, after the miso has been added.

Health Benefits
Tonjiru is not just delicious; it’s packed with goodness!
Miso, a fermented soybean paste, is a powerhouse of probiotics, which are fantastic for gut health. A healthy gut can boost your immune system and even improve digestion. Miso also provides essential minerals like manganese, zinc, and copper.
The array of root vegetables in Tonjiru, such as daikon radish, carrots, and burdock root (gobō), are rich in dietary fiber. Fiber is crucial for digestive health, helps regulate blood sugar, and can contribute to a feeling of fullness. Carrots also provide a good source of Vitamin A, which is important for vision and immune function.
Pork, especially lean cuts, offers a significant amount of high-quality protein. Protein is essential for building and repairing tissues, making enzymes and hormones, and providing energy. It’s also a great source of B vitamins (like B1, B6, and B12) and minerals such as iron and zinc.
Konnyaku (konjac) is a unique ingredient that is virtually calorie-free and packed with glucomannan, a dietary fiber known for its potential to support weight management and cholesterol regulation. It adds a satisfying texture without significant calories.
Serving Suggestions
- Serve Tonjiru as a complete main meal alongside a bowl of steamed white rice. The rice perfectly soaks up the flavorful broth.
- Enjoy it as a hearty side dish to grilled fish (like salmon or mackerel) or chicken teriyaki.
- Pair it with a simple salad dressed with a Japanese-style sesame dressing for a well-rounded meal.
- Meal Prep Ideas: Prepare the soup base and cooked vegetables ahead of time, but add the miso paste just before reheating and serving to maintain its fresh flavor and probiotic benefits.
Storage Tips
Leftover Tonjiru can be stored in an airtight container in the refrigerator for up to 3-4 days. It tastes even better the next day as the flavors deepen! While you can freeze Tonjiru, the texture of some vegetables (like daikon and satoimo) and tofu might change slightly upon thawing. If freezing, cool completely, then transfer to a freezer-safe container for up to 1-2 months. To reheat, gently warm on the stovetop over medium-low heat until simmering. Avoid boiling to protect the miso flavor. You might need to add a splash of dashi or water if it has thickened too much.
