The Origins of Canh Đậu Phụ và Rong Biển
Canh in Vietnamese refers to soup, and it plays an essential role in Vietnamese meals. Soup is a comforting and often light dish that is served with rice as part of a complete meal. The use of tofu and seaweed in soups has its roots in both Vietnamese and broader East Asian cuisine, where these ingredients are celebrated for their nutritional value and versatility.
Tofu, made from soybeans, originated in China over 2,000 years ago and has since become a staple in various cuisines across Asia. It is prized for its ability to absorb flavors from seasonings and broths, making it perfect for soups and stews. Seaweed, on the other hand, has been a part of East Asian diets for centuries, providing not only a salty and savory flavor but also a wealth of nutrients like iodine, calcium, iron, and fiber.
In Vietnamese cooking, Canh đậu phụ và rong biển is often served as a light, refreshing soup that pairs beautifully with the country’s traditional rice dishes. Its simplicity and health benefits make it a common choice for family meals and a popular offering in vegetarian and vegan diets.
The Health Benefits of Tofu and Seaweed
Both tofu and seaweed are known for their numerous health benefits, which make this soup not only delicious but also highly nutritious.
Health Benefits of Tofu
- Rich in Plant-Based Protein: Tofu is an excellent source of protein, particularly for vegetarians and vegans. It contains all nine essential amino acids, making it a complete protein source. A 100-gram serving of tofu provides around 8 grams of protein, supporting muscle growth and repair, and helping to maintain a healthy immune system.
- High in Essential Minerals: Tofu is rich in calcium and iron, both of which are essential for strong bones, teeth, and overall health. Calcium helps to maintain bone density and prevent conditions like osteoporosis, while iron is necessary for the production of hemoglobin, the protein in red blood cells that carries oxygen throughout the body.
- Low in Calories: Tofu is low in calories, making it an excellent option for those looking to maintain a healthy weight. It can be easily incorporated into various meals without adding excess fat or calories, making it an ideal choice for weight management.
- Heart-Healthy: Tofu is naturally low in cholesterol and saturated fat, and its high content of polyunsaturated fats, especially omega-3 fatty acids, can help lower cholesterol levels and improve heart health.
Health Benefits of Seaweed
- Rich in Iodine: Seaweed is one of the best natural sources of iodine, a mineral that is essential for the proper functioning of the thyroid gland. The thyroid regulates metabolism, energy production, and overall hormonal balance. Consuming seaweed regularly can support thyroid health and prevent iodine deficiency.
- Packed with Vitamins and Minerals: Seaweed is a nutrient-dense food that contains a wide range of vitamins and minerals, including vitamins A, C, E, and K, as well as calcium, magnesium, and iron. These nutrients contribute to overall health, including maintaining healthy skin, boosting the immune system, and supporting bone and cardiovascular health.
- High in Fiber: Seaweed is an excellent source of dietary fiber, which is essential for digestive health. The fiber in seaweed helps promote regular bowel movements, prevent constipation, and support gut health.
- Anti-inflammatory Properties: Seaweed contains compounds such as fucoidan and polyphenols, which have been shown to have anti-inflammatory effects. Regular consumption of seaweed may help reduce inflammation in the body, which is linked to many chronic conditions, including arthritis, heart disease, and cancer.
- Supports Weight Loss: Seaweed is low in calories and high in fiber, making it a great addition to a weight-loss diet. The fiber in seaweed helps promote feelings of fullness, reducing the overall calorie intake and supporting healthy weight management.

Ingredients:
- 400 grams of firm tofu (cut into cubes)
- 1 cup of dried seaweed (such as wakame or kelp)
- 1 tablespoon of vegetable oil
- 1 medium-sized onion (sliced thinly)
- 2 cloves of garlic (minced)
- 1 liter of vegetable broth (or water)
- 1 tablespoon of soy sauce
- 1 teaspoon of sugar
- Salt and pepper to taste
- Chopped green onions (for garnish)
- Optional: Sesame oil (for a rich flavor)
- Optional: Chili flakes or fresh chili (for some heat)
Instructions:
- Prepare the Seaweed:
- If using dried seaweed, soak it in warm water for about 10-15 minutes until it softens and expands. Once softened, drain the seaweed and set it aside.
- Prepare the Tofu:
- Drain the tofu and cut it into cubes. You can press the tofu slightly to remove any excess moisture. This will help the tofu absorb the flavors of the soup better.
- Cook the Aromatics:
- In a large pot, heat the vegetable oil over medium heat. Add the sliced onion and sauté for 2-3 minutes until it becomes translucent. Add the minced garlic and cook for another 1-2 minutes until fragrant. Be careful not to burn the garlic.
- Add the Broth:
- Pour the vegetable broth (or water) into the pot and bring it to a simmer. If you’re using water, add a tablespoon of soy sauce for flavor. Stir in the sugar to balance the flavors.
- Add the Tofu and Seaweed:
- Once the broth is simmering, gently add the tofu cubes and the soaked seaweed. Let the soup simmer for about 5-10 minutes, allowing the tofu to absorb the flavors of the broth and the seaweed to soften further.
- Season the Soup:
- Taste the soup and adjust the seasoning with salt and pepper. You can also add a splash of soy sauce for extra umami or a drizzle of sesame oil for a rich, nutty flavor. If you like a bit of heat, add chili flakes or fresh chili slices.
- Serve:
- Once the soup is heated through and the flavors have melded together, remove it from the heat. Ladle the soup into bowls and garnish with freshly chopped green onions.
- Optional Garnishes:
- For added flavor and texture, you can sprinkle sesame seeds or a drizzle of chili oil on top before serving. This will enhance the soup’s flavor and make it even more appealing.
