Tender tofu and dried seaweed float in a light, savory broth for a simple, nourishing soup. This vegetarian, protein-rich family soup is low calorie, healthy, and ready in minutes.
Soak the dried seaweed in cold water for 7–10 minutes until fully rehydrated; drain excess water and chop if long.
In a medium soup pot over medium heat, add sesame oil and minced garlic. Sauté for 30 seconds until fragrant.
Add the rehydrated seaweed and stir for 1 minute to release aroma without letting the garlic brown.
Pour in 6 cups of water and bring to a gentle boil over medium-high heat. Skim any foam that rises.
Cut soft tofu into 1-inch cubes. Gently add tofu to the boiling broth to avoid breaking; simmer on low heat for 4–5 minutes.
Season with soy sauce, salt, and black pepper. Stir gently so tofu stays intact, then simmer for 2 more minutes.
Slice green onions thinly and add just before turning off the heat for a fresh, vivid aroma.
