Ingredients
To make this rich and satisfying Japanese Sweet Potato Soup, gather the following ingredients:
- Oyster Mushrooms: A 1/2 pound of these juicy mushrooms brings an earthy flavor and buttery texture to the soup.
- Garlic: Four cloves, thinly sliced, add aromatic depth to your dish.
- Birdseye Chilies: Use three small chilies for a kick of heat, or reduce to two if you’re sensitive to spice.
- Ginger: A 1/4 cup of thinly sliced ginger will infuse the soup with a warm, pungent essence.
- Scallions: Four ounces (about 4 large or 7 small) provide a fresh and slightly sharp flavor.
- Japanese Sweet Potatoes: Two pounds of these creamy potatoes will lend natural sweetness and a rich texture.
- Extra-Virgin Olive Oil: Two tablespoons for sautéing the vegetables.
- White Miso Paste: A 1/4 cup adds umami and a touch of saltiness.
- Coconut Milk: Two 13.5-ounce cans of full-fat, unsweetened coconut milk provide creaminess and a rich flavor.
- Water: Five cups will help create the soup base.
- Bok Choy: Ten ounces, about two heads, bring a crunchy texture and mild green flavor.
- Frozen Edamame Beans: Two cups, shelled, for added protein and color.
- Diamond Crystal Kosher Salt: To taste, enhancing the overall flavor.
- Fresh Mint Leaves (optional): For a refreshing garnish.
The vibrant color of the sweet potatoes, the earthy aroma of the mushrooms, and the spice from the chilies all combine to create a delightful experience for the senses.
Step-by-Step Directions
-
Prepare the Mushrooms: Begin by cutting off the base of the oyster mushroom cluster and discard it. Tear the oyster mushrooms into strips to create a rustic texture.
-
Chop Aromatics: Thinly slice the four garlic cloves, the knob of fresh ginger, and the Birdseye chilies. Set these aromatic ingredients aside.
-
Slice Scallions: Halve the scallions; slice the white parts into medallions and set them aside. Thinly slice the green parts at an angle for garnish later.
-
Cut Sweet Potatoes: Dice the Japanese sweet potatoes into bite-sized pieces and set aside, ready to enrich the soup with their natural sweetness.
-
Sauté the Mushrooms: Place a large Dutch oven or stock pot over medium heat and add the two tablespoons of olive oil. Add the mushrooms and cook undisturbed for 4 minutes until they start browning. Continue to cook for an additional 5-6 minutes, stirring occasionally until the mushrooms are deeply browned and reduced in size. If they begin to burn, lower the heat.
-
Add Aromatics: Incorporate the sliced garlic, chilies, and white parts of the scallions into the pot. Add 1/4 cup of miso paste and mix everything to form a paste. Cook for 2 minutes, allowing the flavors to meld.
-
Combine Ingredients: Add the diced Japanese sweet potatoes to the pot and stir to combine. Pour in the five cups of water and the two cans of coconut milk, followed by the sliced ginger.
-
Simmer: Bring the mixture to a simmer, cover the pot, and reduce heat to low. Allow it to simmer for 20-25 minutes or until the sweet potatoes are tender but not disintegrating.
-
Add Bok Choy: Uncover the pot. If desired, remove the ginger slices (or leave them in). Tear in the bok choy leaves, stir to combine, cover, and let simmer for another 5 minutes.
-
Finish with Edamame: Add the frozen edamame beans to the pot and stir well. Keep the pot on heat for another 2 minutes to completely thaw the edamame into the soup.
-
Season and Serve: Taste the soup and adjust the seasoning with kosher salt as needed. Remove it from heat, and to serve, top with the reserved scallion greens and mint. Enjoy warm!
Tips & Tricks
- Miso Paste: For a milder flavor, consider reducing the amount of miso paste. Alternatively, you can use a different type of miso for varying flavor profiles.
- Heat Control: If you prefer a milder soup, add fewer Birdseye chilies or deseed them before use.
- Add Protein: Consider adding shredded chicken or tofu for an extra protein boost if desired.
- Ginger Variations: If you aren’t keen on ginger’s flavor, adjust the quantity according to your taste preferences.
