Prepare the ingredients by preparing the dashi, dicing the green onion, and cutting the tofu into 1/2 (1 cm) cubes.
Bring the dashi to a simmer on medium heat. Once the dashi comes to a boil, turn off the heat.
In a separate bowl, mix a couple ladles of the hot broth with the miso paste and stir until the miso paste is dissolved. Once dissolved, add the miso and broth mixture to the soup.
Add small amounts at a time of miso paste to the dashi. Stir to dissolve until the miso paste is fully dissolved before adding more. You can use a fine mesh strainer to help you dissolve the miso paste into the dashi.
Add the tofu, kamaboko, diced green onion, and the dried wakame seaweed to the miso soup and gently stir in to combine for a minute or two. Tip: Make sure you are ready to serve the soup prior to adding these last few ingredients as it's best when they are freshly added.
Serve and enjoy!
