15-Minute Miso Soup with Tofu and Greens

15-Minute Miso Soup with Tofu and Greens

This is a quick miso soup built from broth, miso paste, tofu, green onion, leafy greens, and optional seaweed. The most important step is adding the miso off the heat, so the soup keeps its clean, rounded flavor.

Use dashi if you want a more traditional base, or vegetable broth if you want the recipe to stay vegan. Either way, keep the broth at a gentle simmer rather than a hard boil.

Ingredient Groups

Broth Base

Dashi gives the soup a light savory base. Vegetable broth also works, especially with a small piece of kombu or a little seaweed for extra depth.

Nori is optional. Wakame is a better fit if you have it, but nori is easy to find and still adds a mild seaweed note.

Miso

White miso is mild and slightly sweet, which works well for a quick soup. Yellow miso has a stronger flavor. Start with the amount listed, then add more only after tasting.

Do not boil the miso after adding it. Whisk it with a little hot broth in a separate bowl first, then stir it into the pot once the heat is off.

Greens and Tofu

Firm tofu is easy to cube and holds together well. Silken tofu can also be used, but add it near the end and stir gently.

Chard, spinach, bok choy, kale, or other greens all work. Sturdy greens need a few minutes in the broth; tender spinach only needs a short wilt.

Step-by-Step Method

1. Warm the Broth

Bring the dashi or vegetable broth to a gentle simmer in a medium saucepan. Add the greens, green onion, and tofu, then simmer for about 5 minutes.

2. Loosen the Miso

Spoon a little hot broth into a small bowl. Whisk in the miso paste until smooth so it does not clump in the soup.

3. Finish Off the Heat

Turn off the heat, then stir the miso mixture back into the pot. Add the nori or another seaweed, taste, and adjust with more miso if needed.

4. Serve

Serve warm as a light lunch, starter, or side dish. If you want it to be more filling, add mushrooms, soba noodles, rice, or extra tofu.

Storage and Make-Ahead

Miso soup is best served fresh. Leftovers can be refrigerated for up to 2 days, but reheat gently and avoid boiling.

If making it ahead, prepare the broth, greens, and tofu first. Add the miso only when reheating and serving.

Serving & Goal Fit

This is a light, low-calorie soup with modest protein from tofu. For a fuller balanced meal, serve it with rice, soba noodles, edamame, eggs, fish, tofu, or another protein-rich side.

For a lower-sodium bowl, use low-sodium broth and start with less miso, then adjust at the end.
