Even though the frigid winter weather is behind us, there’s still cold and rainy spring days ahead of us. Yesterday was one of those. It had that classic March dampness that chills you to your core.
Sure, I could harp on the cold, but I like to think of it as perfect soup weather instead! And isn’t it just great timing that I’m writing about a new bok choy miso soup recipe today?! I think so.
If you’re not familiar with bok choy, or miso for that matter, they are two ingredients commonly used in Asian cuisine. Bok choy is a type of Chinese cabbage also known as pak choi. It has crunchy white stalks and green leaves that have a mildly bitter taste. Miso is a paste made from fermented soybeans and grains that contributes a salty, umami flavor to recipes.
In this bok choy miso soup, these ingredients shine alongside meaty mushrooms, soba noodles, and enough ginger, garlic, and red pepper flakes to clear your sinuses. The whole dish is a wonderful marriage of flavors, and I know I’ll be making it on repeat. Enjoy!

- Pour in the broth and stir in the white miso paste. Bring to a boil.

How do you cut bok choy for soup?
You can use large or baby bok choy for soups. Bok choy is more manageable to eat in soups when it’s roughly chopped.
To prepare bok choy in this way, trim a little bit off the root end. Wash the bok choy leaves under cold water to remove any dirt that got stuck in between them, and pat dry. If using baby bok choy, roughly chop the leaves across the stems. This is what I did for this bok choy miso soup. See How to Cut Bok Choy for more tips.
If using large bok choy, use a sharp knife to remove the stalks from the leaves. Dice the stems, then chop up the leaves. Some soup recipes may call for you to halve baby bok choy (keep the root intact) and add them to the soup instead of chopping it up (like my Spaghetti Squash “Ramen”).
Expert Tips
- You can find miso paste at most large grocery stores and Asian markets. I usually find it in the refrigerated condiment area in the produce section. It might be next to containers of tofu, other specialty ingredients that require refrigeration, and/or salad dressings, for example.
- Miso lasts a long time in the fridge, so I encourage you to try some other recipes that use it after making this bok choy miso soup! Check out my Roasted Japanese Turnips (with maple miso butter) and Roasted Golden Beets with Miso Maple Sauce.
- Soba noodles (buckwheat noodles) can be found in the international aisle of grocery stores. I really like these soba noodles. They are not gluten free, because they have wheat flour in addition to buckwheat, but they taste really good.
- Bok choy is available at most stores in the produce section. FYI – Trader Joe’s sells baby bok choy in pre-packaged bags labeled Shangai Bok Choy.
- This soup keeps well in the fridge for up to 3 days. Reheat in a saucepan over medium heat on the stove, stirring occasionally, until warmed through. The soba noodles will absorb the broth over time, so add more liquid as needed when reheating.

Equipment
soup pot
Ingredients
- 1 tablespoon toasted sesame oil
- 1 yellow onion - chopped
- 8 ounce cremini mushrooms - sliced
- 1 tablespoon chopped fresh ginger
- 3 cloves garlic - minced
- ¼ teaspoon red pepper flakes
- 6 cups vegetable broth
- 2 tablespoon sweet white miso
- 4 ounce soba noodles - dry
- 2 heads baby bok choy - roughly chopped, about 3 to 4 cups
- 1 tablespoon lemon juice
Instructions
Heat the sesame oil in a large soup pot over medium heat. Add the onion, mushrooms, ginger, garlic, and red pepper flakes. Cook until the onion is translucent, stirring frequently, about 5 to 7 minutes.
Pour in the vegetable broth and add the miso paste. Use your spoon to break up the miso as needed. Increase heat and bring to a boil.
Add the dry soba noodles to the pot, and cook according to package instructions until tender. Mine usually take about 6 to 8 minutes.
Halfway through the noodle cooking time, stir in the chopped bok choy. Once the noodles are tender and the bok choy has wilted, stir in the lemon juice. Taste and adjust seasonings as desired.
Notes
- This serves 4 as a side and 2 or 3 as a main dish. Feel free to add tofu for more protein.
- Look for miso in the refrigerated condiment section of your grocery store. Soba noodles are usually found in the international aisle.
- Keep leftovers in an airtight container in the fridge for 3 days. Reheat in a saucepan over medium heat, stirring occasionally, until warmed through. If the noodles have absorbed most of the broth, add more liquid as needed while reheating.
