5 servings, about 3/4 cup each


  • ¼ cup crumbled dried seaweed, such as wakame or kelp (see Tip)

  • ¼ cup diced strip steak (optional)

  • ¼ cup thinly sliced scallions

  • 2 teaspoons minced garlic

  • 2 teaspoons toasted sesame oil

  • ¼ teaspoon freshly ground pepper

  • 4 cups water

  • 2 tablespoons white miso (see Note), or to taste

  • ½ cup diced firm tofu


  1. Place seaweed in a medium bowl, cover with water and let soak for 20 minutes.

  2. Combine steak (if using), scallions, garlic, sesame oil and pepper in another bowl.

  3. Warm a medium saucepan over high heat and add the scallion mixture. Cook, stirring, until fragrant, about 1 minute. Stir in 4 cups water and miso. Reduce the heat to medium-low so the liquid does not boil. Whisk to dissolve the miso.

  4. Drain the seaweed and stir it into the soup along with tofu. Cook over medium-low for about 10 minutes. Remove from the heat. Taste and season with more miso, if desired.


Tip: Look for wakame in natural-foods stores or Asian markets.

Note: Miso is fermented bean paste made from barley, rice or soybeans, and is used to add flavor to dishes such as soups, sauces and salad dressings. It is available in different colors, depending on the type of grain or bean and how long it's been fermented. In general, the lighter the color, the milder the flavor. It will keep in the refrigerator for at least a year.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
