How to Make Japanese Tonjiru (Pork Miso Soup)
Japanese cuisine is renowned for its delicate flavors and healthy ingredients, with one of its hidden gems being Tonjiru, or Pork Miso Soup. This hearty soup is a staple in Japanese households, offering a comforting blend of pork, vegetables, and miso paste. In this comprehensive guide, we’ll walk you through the process of making this delicious dish, perfect for warming up on a chilly day.

What is Tonjiru?
Tonjiru translates to “pork soup” in English, and it’s a variation of the more commonly known miso soup. While traditional miso soup is a light broth featuring dashi, tofu, and seaweed, tonjiru is a more robust version with additional ingredients like pork and root vegetables. The inclusion of pork adds a rich umami flavor, making it a filling and nutritious meal.
Ingredients for Tonjiru
To make a classic tonjiru, you’ll need the following ingredients:
- 200g thinly sliced pork belly
- 1 cup dashi stock
- 3 tablespoons miso paste
- 1 medium carrot, sliced
- 1 medium daikon radish, sliced
- 1 potato, peeled and cubed
- 1 onion, sliced
- 1 tablespoon soy sauce
- 1 tablespoon sake
- 2 tablespoons vegetable oil
- 2 cups water
- 1 green onion, chopped for garnish

Step-by-Step Guide to Making Tonjiru
Step 1: Prepare the Ingredients
Before you start cooking, gather all the ingredients. Slice the pork belly into bite-sized pieces, and prepare the vegetables by slicing the carrot, daikon radish, and onion. Peel and cube the potato, ensuring all pieces are evenly sized for uniform cooking.
Step 2: Sauté the Pork and Vegetables
In a large pot, heat the vegetable oil over medium heat. Add the sliced pork belly and cook until it turns golden brown. This process helps render the fat, adding depth to the soup’s flavor. Next, add the onion, carrot, daikon radish, and potato. Sauté for about 5 minutes until the vegetables begin to soften.
Step 3: Add the Broth and Simmer
Pour the dashi stock and water into the pot, stirring to combine with the sautéed ingredients. Bring the mixture to a boil, then reduce the heat to a simmer. Cover the pot and let it cook for 15-20 minutes, or until the vegetables are tender.
Step 4: Incorporate Miso Paste and Seasonings
Once the vegetables are cooked, add the miso paste to the soup. It’s crucial to dissolve the miso properly, so use a small strainer or ladle to mix it with some broth before incorporating it into the pot. Stir in the soy sauce and sake for additional flavor.
Step 5: Final Touches and Serving
Taste the soup and adjust the seasonings if necessary. When satisfied, ladle the tonjiru into individual bowls and garnish with chopped green onion. Serve hot, and enjoy the comforting flavors of this traditional Japanese dish.

Health Benefits of Tonjiru
Tonjiru is not only delicious but also packed with nutrients. The combination of pork and vegetables provides a balanced mix of protein, vitamins, and minerals. Pork is an excellent source of thiamine, vitamin B6, and niacin, which are essential for energy metabolism and maintaining a healthy nervous system. The vegetables add fiber and antioxidants, promoting a healthy digestive system and reducing inflammation.
Tips for the Perfect Tonjiru
- Use quality ingredients: Choose fresh vegetables and high-quality pork for the best flavor.
- Balance the miso: Miso can be quite strong, so add it gradually and taste as you go to avoid overpowering the soup.
- Experiment with vegetables: While the traditional recipe calls for certain vegetables, feel free to add mushrooms, taro, or even seaweed for variety.
- Cook with care: Avoid boiling the miso, as it can lose its nuanced flavors. Simmer the soup gently to preserve its taste.
