Once stock is boiled, turn the heat down to low. Transfer about 1 cup of stock to a cup and stir in miso paste. Stir until miso paste is fully dissolved.
Pour the miso mixture back into the stock.
Add tofu and green onion. Simmer gently for 2 minutes and serve. (TIP: Don’t bring the soup to a boil after adding miso paste!)
Notes
Note 1a: I often use this dashi granules (equivalent of chicken bullion) to make a quick dashi stock. Simply bring 4 cups of water to a boil and stir in 2 teaspoons of dashi powder.Note 1b: You can also use chicken stock, or vegetable stock, or clam stock instead of dashi.Note 2:White miso pasteis milder, while red miso pastehas a stronger taste. I prefer to use a combination of both. If you’re new to miso soup, I recommend buying white miso paste.
