Have you ever tasted a soup that warms your body and your heart? 💛 What if I told you there’s a Japanese comfort food that does just that—with juicy pork, fresh vegetables, and a deep umami flavor from miso? If you’re wondering what makes tonjiru so comforting and satisfying, you’re in the right place!

Whether it’s a chilly day or you’re simply craving a wholesome meal, tonjiru is the perfect answer. But here’s the best part—it’s quick, healthy, and super easy to make!

🍜 What Is Tonjiru?

Tonjiru, also called butajiru (which means “pork soup” in Japanese), is a miso-based soup filled with thinly sliced pork belly and hearty vegetables. Unlike regular miso soup, this version is extra rich thanks to the pork and earthy ingredients like burdock root and daikon radish. 💪🌱

It’s a dish often served in Japanese homes and school lunches. The soup comes together in under 30 minutes, making it perfect for busy weeknights. 🕒✅

🥕 What You’ll Need: Ingredients Breakdown

Here’s everything you need to make a soul-warming bowl of tonjiru. These ingredients come together like a warm hug from Japan! 🫶

🧾 Main Ingredients:

• 150g pork belly, thinly sliced – the star of the soup, adding flavor and richness
• 600ml dashi stock – a Japanese broth made from kombu and bonito flakes (or use instant dashi powder!)
• 2 tbsp miso paste – adds that famous umami flavor (white or red miso works)

🥦 Vegetables (feel free to swap based on what you have!)

• 100g daikon radish, peeled and sliced
• 100g carrots, cut into half-moons
• ½ block konnyaku (a jelly-like food made from yam), sliced
• 100g potatoes, cubed
• 40g burdock root (gobo), shredded or thinly sliced
• 2 scallions, cut into 1-inch pieces

✨ Garnish (optional but amazing)

• Thinly sliced white part of scallion (for a fancy touch)
• A pinch of shichimi togarashi (Japanese chili blend) for spice lovers 🌶️

🧾 Ingredient Notes:

You don’t need to stick strictly to pork belly for tonjiru, but whichever cut you use, make sure it’s thinly sliced. This helps it cook quickly and stay tender. Personally, I prefer pork belly because it adds extra depth and richness thanks to its natural fat. If you enjoy a meatier bite, slightly thicker slices also work well—just adjust the cooking time a bit. 🐖

As for the veggies, there’s plenty of flexibility! Traditional ingredients in tonjiru typically feature daikon, carrots, taro, burdock, konnyaku, and green onions. But feel free to get creative—onions, potatoes, tofu, mushrooms, string beans, or even aburaage (crispy fried tofu) make great additions. 🥕🍄

Let’s talk konnyaku for a second. It’s a firm, jelly-like food made from konnyaku potato flour. You’ll usually find it sold in blocks or shaped into little balls. n western Japan (Kansai), thinly sliced konnyaku is called ito konnyaku, while in eastern regions like Kanto, it’s referred to as shirataki.

Konnyaku is low in calories and packed with fiber. While it doesn’t carry much flavor on its own, it’s loved for its chewy texture and its ability to add volume and variety to dishes without making them heavy. 💡

👩‍🍳 How to Make Tonjiru – Step-by-Step

Follow these simple steps and enjoy the cozy aroma filling your kitchen. 😍

1. Sauté the Pork

Add a small amount of oil to a medium-sized pot and warm it over medium heat. Add the pork slices and cook over high heat until the meat turns white and slightly golden on the edges. This step builds flavor—don’t skip it!

2. Add the Veggies

Toss in all the vegetables except the scallions. Sauté the vegetables for a couple of minutes until they begin to soften. The potatoes will look a little see-through—perfect! 🥔✨

3. Pour in the Dashi

Add the dashi stock and bring everything to a boil. When the soup begins to boil, reduce the heat to a gentle simmer. Let it cook for about 10 minutes, or until the vegetables are nice and tender.

4. Stir in the Miso

Slowly mix the miso into the soup using a ladle or fine mesh strainer, making sure it fully blends without clumps. (Don’t just plop it in—it won’t mix well.) Once the miso is fully blended, toss in the scallion pieces. Let them simmer for 2-3 minutes.

5. Serve and Garnish

Ladle the soup into bowls, top with scallion slivers and a sprinkle of togarashi if you like it spicy. 🍜🔥

🥄 Time to Serve!

Serve tonjiru hot in medium bowls, either on its own or alongside a bowl of steamed rice. 🍚 It’s also amazing with onigiri (rice balls) or even some pickled vegetables on the side. Every bite is rich, flavorful, and deeply comforting.
