This Crock Pot Miso Soup is a light and nourishing recipe, which includes miso paste and tofu. It’s a healthy twist on the classic, ready in about 2 hours and 10 minutes.
Crock Pot Miso Soup Ingredients
- 4 cups vegetable broth (or dashi for traditional flavor)
- 1 sheet nori (optional, cut into large rectangles; yields about 1/4 cup)
- 3–4 tablespoons white or yellow miso paste (chickpea or soy-based; avoid bonito for vegan option)
- 1/2 cup chopped green chard (or other sturdy green)
- 1/2 cup chopped green onion
- 1/4 cup firm tofu, cubed (or silken tofu added at the end)
How To Make Crock Pot Miso Soup
- Add base ingredients: Pour vegetable broth into the Crock Pot. Add chard, green onion, and firm tofu (if using silken tofu, wait until the end). Stir to combine.
- Cook the soup: Cover and cook on LOW for 1.5–2 hours or on HIGH for about 1 hour, until the vegetables are tender.
- Prepare miso paste: While the soup cooks, place miso paste in a small bowl. Add a bit of hot broth or water and whisk until smooth. This prevents clumping.
- Finish with miso and nori: Once the soup is done cooking, stir in the miso mixture and nori. If using silken tofu, gently add it now. Do not boil after adding miso.
- Taste and serve: Taste and adjust seasoning with more miso or a pinch of sea salt. Serve warm. Best enjoyed fresh.

Recipe Tips

Add silken tofu at the end after cooking to prevent it from breaking apart. - Is miso soup vegan?

Yes, but add miso paste just before serving to preserve flavor and nutrients. - What greens can I substitute?

FAQs
Can I use red miso instead of white?
Yes, but red miso has a stronger, saltier flavor. Use less to start.
Can I skip the tofu?
Yes, but tofu adds protein and texture. You can substitute mushrooms or edamame.
Why shouldn’t I boil miso paste?
Boiling destroys beneficial probiotics and dulls the flavor.
What does nori add to miso soup?
Nori adds a subtle umami flavor and traditional texture.
Can I double the recipe?
Yes, just be sure not to overcrowd your Crock Pot.
