Prep the Ingredients: Chop cabbage, tomato, and onion into bite-sized pieces.
Simmer the Vegetables: In a medium saucepan, add the cabbage, tomato, onion, and water. Bring to a boil over medium heat, then reduce the heat and simmer for about 5 minutes, or until the vegetables are tender.
Add the Miso Paste: Turn off the heat. Add the miso paste and stir gently until fully dissolved.
Serve: Pour into bowls and enjoy warm!
Notes
Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
This miso soup is made without dashi, but if you prefer a deeper flavor, feel free to add a bit of dashi powder.
If the soup tastes a bit light, add a little more miso paste to deepen the flavor.
Always add the miso after turning off the heat—boiling it can reduce its delicate aroma and taste.
