I first created this recipe when I wanted something other than vegan chicken noodle soup to help perk my family up when they were down with a cold. The soup needed to come together fairly quickly so I could spend more time looking after my little ones in their moments of need, and bok choy miso noodle soup really delivered. Now, whenever anyone in my family comes down with a case of the sniffles, I waste no time making this soup.

👩🏽‍🍳 Why I Love This Recipe

It is sometimes hard to believe that this bok choy miso noodle soup contains such simple ingredients, yet it yields complex and comforting flavors. I love the savory broth mixed with the rich umami flavor of the mushrooms. The bok choy is tender but retains a slight bite, which adds interesting texture to the soup. As a health coach, I know why miso is incredibly healthy, and all of its potential benefits, such as immune system support, make me love this soup even more.

Unlike a lot of soups, which need plenty of time on the stove, the broth in this bok choy miso noodle soup develops its flavor surprisingly quickly. I whisk the miso with hot water until smooth before mixing in the tamari and mirin, then saute the mushrooms in that mixture so they absorb all the flavors. After adding the bok choy and remaining broth, the vegetables cook just until tender before I add my noodles and tofu.

Whether I need to detox or a homemade remedy for a common cold, I always make this soup. In fact, I have become quite well known for it among my friends and family. If anyone is under the weather, you can bet I will be there with a flask of piping hot, freshly made soup. Last month I caught one of my boys out on a lie. He was very obviously faking being sick, and I thought it was to get out of school. When he finally came clean, he told me it was because he was really craving miso soup. Ha! Please do not feel like you need to wait for a reason to make this soup. Whip up a batch tonight.

🥘 Ingredients

This is everything I use to create a savory and flavorful bok choy miso noodle soup:

Broth: I combine chickpea miso paste, tamari or soy sauce, mirin, and hot water for a balanced broth with plenty of umami flavor.

Vegetables: Baby bok choy and portobello mushrooms are the stars of this soup. The mushrooms provide a savory meaty texture, and the bok choy stays tender and vibrant.

Noodles: Almost any asian noodle works well here. I like using shirataki noodles for a lighter option, but ramen, rice noodles, soba, or udon are all delicious choices.

Optional protein: firm or extra firm tofu are great for adding extra protein to the soup. I like using crispy baked tofu for additional texture.

🔪 How To Make

Once I have all of my vegetables prepped, making this bok choy miso noodle soup is extremely easy. This is how I do it:

Prepare ingredients: First, I coarsely chop the bok choy, thinly slice the mushrooms, and cook the noodles according to the package directions. If I am using tofu, I press, cut, season, and bake it in the oven until crispy.

Make broth base: Then, I whisk the miso with a little hot water until smooth, and stir in the tamari and mirin until fully combined.

Cook the vegetables: I add the mushrooms and broth mixture to a large pot and cook for a few minutes until the mushrooms begin to soften. After that, I stir in the bok choy with the remaining hot water and simmer until tender.

Add the noodles: If I am using tofu, I add it to the pot, then stir in the cooked noodles, or divide it among serving bowls before ladling the soup over the top.

Serve: I finish each bowl with crispy tofu, green onions, sesame seeds, or my favorite toppings and serve hot.

💭 Expert Tips

My #1 Secret Tip for this bok choy miso noodle soup recipe is to dissolve the miso completely before adding it to the pot. Whisking it with a small amount of hot water first is how I create a silky smooth broth without little bits of undissolved miso.

Other Tips To Keep In Mind:

Cook the noodles separately: If I suspect that I will have leftovers, I cook and keep the noodles separate from the broth until serving. They stay pleasantly chewy instead of soaking up the broth and becoming soft.
Do not overcook the bok choy: Bok choy only needs a few minutes to become tender. I cook it just until the stems are crisp-tender to help preserve its texture and bright green color.
Slice mushrooms thinly: Thin slices cook quickly and absorb more of the miso broth, giving every bite lots of flavor.
Marinate the crispy tofu overnight: If I am making the crispy tofu option, I marinate it overnight so that it has even more flavor before baking.
Taste before serving: Different brands of miso and tamari vary in saltiness, so I always taste the broth before serving and adjust with a little extra hot water or tamari if needed.

📖 Variations

Once I had the basic broth just the way I liked it, I started experimenting with different vegetables and toppings for this bok choy miso noodle soup. These variations all keep the same base while creating something a little different:

Spicy kimchi: Kimchi adds a wonderful tangy heat that pairs really well with the savory broth. I stir a spoonful into each bowl just before serving, then finish everything with chili crisp, sliced green onions, and sesame seeds. I love making this when I have a blocked nose, as it opens up my sinuses.

Coconut curry: For a creamier twist, I replace about 1 cup of the hot water with light coconut milk and whisk a spoonful of yellow curry paste into the broth before adding the vegetables. I love using spinach, mushrooms, and mange tout in this version.

Edamame and corn: Shelled edamame, sweet corn, and thinly sliced carrots add extra protein, sweetness, and color without changing the simplicity of the recipe. This variation is especially popular with my boys thanks to its colorful appearance.

🍽 Serving Suggestions

I love serving this bok choy miso noodle soup with plenty of sides that can be added to the soup, like miso mushrooms or crispy air fryer tempeh. I also recommend finishing off the meal with something light and fruity, like mango mochi ice cream.

When I make this at home on a normal weeknight, I usually serve it with homemade vegan sushi, or tofu skewers with ginger soy marinade if my boys are extra hungry. And if I am making it for someone who is feeling a little ill, I like following it up with lavender milk tea to promote relaxation and vegan mochi donuts because nothing makes my kids happier than a little sweet treat.

🧊 Storing And ♨️ Reheating

Refrigeration: I store the broth, vegetables, and tofu in an airtight container in the refrigerator for up to 4 days. If it is at all possible, I recommend storing the tofu and noodles separately.

Freezing: I freeze the broth for up to 3 months without the noodles, and prepare fresh noodles when reheating.

Reheating: If frozen, I thaw the soup in the refrigerator overnight, then warm it gently over medium-low heat until hot. If the leftover noodles were stored separately, I add them during the last few minutes to warm through.

❓Recipe FAQs

How can I fix my miso broth if it is grainy, but I have already added the vegetables?

Grainy broth usually means the miso paste was not fully dissolved before it was added to the soup, but it is easy to improve the texture. I like removing the pot from the heat first, then using a fine mesh strainer to press the broth through with the back of a spoon into another large pot or bowl. The veggies can stay in the original pot while you work. I whisk the broth gently to help break apart any miso clumps and pour it back over the vegetables once it is smooth. If it is still grainy after whisking, pour the broth through a clean piece of cheesecloth, and adjust the taste with a bit more miso if needed. Just be sure to mash it up into a smooth paste before adding it in.

Can I substitute the chickpea miso with another type?

I love chickpea miso for its mild, slightly sweet flavor that allows the vegetables and noodles to shine without overpowering the soup. It is also naturally soy-free. If you cannot find chickpea miso, white miso is an excellent substitute. Yellow miso creates a slightly bolder, saltier soup, so I recommend tasting before adding extra tamari. Red miso has a more robust fermented flavor that is delicious but noticeably stronger, which is why I would start with a little less and adjust to taste.

What can I use if I cannot find miso paste?

Miso gives this soup its distinctive flavor, so there is no exact substitute. If I absolutely cannot find it, I make a simple broth using low-sodium vegetable broth, tamari, a splash of mirin, freshly grated ginger, garlic, and a small piece of kombu if I have it. The finished soup will not have the same fermented richness or gentle sweetness, but it will still taste good.
