Ingredients
- 300 g fresh oysters
- 1 block soft tofu
- 200 g king oyster mushrooms
- 3 cloves garlic
- 1 piece fresh ginger
- 2 tbsp miso paste
- 1 tbsp light soy sauce
- 1 tbsp cooking wine
- 1/2 tsp white pepper
- 1 pinch salt
- 2 stalks green onions
- 2 tbsp cooking oil
Instructions
- 1Slice the mushrooms

Place the king oyster mushrooms on a cutting board and slice them into manageable pieces. These mushrooms will provide a meaty texture to the soup.
Tip: Keep the slices uniform for even cooking. - 2Tear mushrooms into strips

After slicing, take the king oyster mushroom pieces and tear them into smaller, thinner strips by hand. Tearing them helps them absorb the soups flavors better than clean cuts.
Tip: Hand-tearing creates an uneven surface area which is perfect for capturing the miso broth. - 3Prepare the ginger

Take fresh ginger and carefully slice it into thin pieces. This will be used as a primary aromatic for the soup base.
Tip: Thinly slicing the ginger ensures it infuses its warmth evenly throughout the broth. - 4Crush the garlic

Take three to four cloves of garlic and crush them using the flat side of your knife blade. Crushing releases the essential oils, providing a stronger garlic flavor for the soup.
Tip: Crushed garlic is more aromatic than finely minced garlic when stir-frying for soups. - 5Cut the tofu

Carefully take the block of soft tofu and cut it directly into small, uniform cubes while it is still in its container to maintain its shape.
Tip: Using soft tofu provides a delicate, silky texture that pairs well with the miso broth. - 6Aromatize the oil

Heat oil in your pot and add the prepared ginger slices. Sauté them briefly until the oil becomes fragrant and the ginger is slightly golden.
Tip: Watch the heat carefully so the ginger doesnt burn, just get it fragrant. - 7Sauté the aromatics

In a pot with heated oil, add the sliced ginger and crushed garlic cloves. Stir-fry over medium heat until the aromatics are fragrant and lightly golden.
Tip: Be careful not to burn the garlic; once it releases its aroma, its ready for the next ingredients. - 8Add the tofu

Gently add the small blocks of soft tofu into the pot with the sautéed ginger and garlic. Take care when adding the tofu to keep the pieces intact.
Tip: Use a wide spatula or ladle to gently move the tofu so it doesnt break apart. - 9Season with soy sauce

Pour a splash of light soy sauce over the tofu in the pot to begin seasoning the base of the soup.
Tip: Adding the soy sauce now allows the tofu to absorb the savory flavor. - 10Prepare the miso

In a small bowl, combine the miso paste with a little bit of hot water. Use a spoon to mix until the miso is completely dissolved and smooth.
Tip: Pre-dissolving the miso prevents clumps from forming in your soup. - 11Add the miso

Pour the prepared, dissolved miso mixture into the pot, stirring gently to incorporate it into the broth with the tofu and mushrooms.
Tip: Stir gently to ensure the miso is evenly distributed throughout the soup without breaking the tofu. - 12Add the oysters

Add the raw oysters to the pot. Arrange them carefully on top of the other ingredients.
Tip: Adding the oysters at the end ensures they remain plump and tender. - 13Season the oysters

Add a splash of cooking wine to the pot to enhance the flavor of the oysters and remove any fishy smell.
Tip: Be careful not to overcook the oysters; they only need a few minutes to become plump and tender. - 14Season with white pepper

Sprinkle a dash of white pepper over the oysters to provide a mild, aromatic heat that complements the seafood.
Tip: White pepper is perfect for soups because it adds flavor without changing the color of the broth. - 15Add salt to season

Add a pinch of salt to the pot to balance and elevate all the flavors in the Miso Oyster Tofu Soup.
Tip: Taste the broth before adding salt, as the miso already provides a significant amount of savory saltiness. - 16Garnish and serve

Finally, sprinkle fresh chopped green onions over the hot soup. The fresh greens add a bright pop of color and a crisp, oniony finish.
Tip: Serve immediately while the soup is steaming hot to enjoy the best texture of the oysters.
