Instructions
- 1
Preheat your oven to 400°F (200°C). Peel and dice the sweet potatoes into evenly sized cubes. Spread them on a baking sheet, drizzle with olive oil, season with a pinch of salt, and roast for 20-25 minutes until tender and slightly caramelized.

In a large pot, heat 1 tablespoon of sesame oil over medium heat. Add the diced onion and sauté for 3-4 minutes until softened and translucent. Stir in the minced garlic and grated ginger, cooking for another 1-2 minutes until fragrant.
- 3
Add the roasted sweet potatoes to the pot along with the vegetable broth, miso paste, and soy sauce. Stir to combine and bring the mixture to a gentle simmer. Let it cook for 10 minutes, allowing the flavors to meld together.
- 4
Using an immersion blender (or carefully transferring to a countertop blender in batches), purée the soup until smooth and creamy. Stir in the coconut milk and season to taste with salt and pepper. Keep warm on low heat.

In a skillet, heat the remaining tablespoon of olive oil over medium-high heat. Add the sliced shiitake mushrooms and cook for 5-7 minutes, stirring occasionally, until crispy and golden brown. Season lightly with salt and set aside.
- 6
To make the sesame scallion oil, combine the thinly sliced green onions, toasted sesame oil, and sesame seeds in a small saucepan over low heat. Cook for 1-2 minutes, stirring often, until the scallions soften and the oil becomes fragrant. Add a pinch of red pepper flakes if desired.

To serve, ladle the soup into bowls and top with crispy shiitake mushrooms. Drizzle the sesame scallion oil over each bowl and garnish with additional sesame seeds or green onions if desired. Serve warm and enjoy!

Frequently Asked Questions
Q: Can I use a different type of potato instead of sweet potatoes?
A: Yes, you can substitute sweet potatoes with other starchy vegetables like butternut squash, carrots, or even regular potatoes. However, keep in mind that the flavor will change slightly, as sweet potatoes contribute a natural sweetness to the soup.
Q: What can I use instead of white miso paste?
A: If you don’t have white miso paste, you can use yellow miso as a substitute. If miso isn’t available, try adding a small amount of soy sauce or tamari for a similar umami flavor, though it won’t have the same depth of flavor as miso.
Q: Can I make this soup ahead of time?
A: Yes, this soup can be made ahead of time. Prepare the soup as instructed but hold off on making the crispy shiitake mushrooms and sesame scallion oil until just before serving. Store the soup in an airtight container in the refrigerator for up to 4 days. Reheat gently over low heat, stirring occasionally.
Q: How should I store leftovers, and can I freeze this soup?
A: Store leftovers in an airtight container in the refrigerator for up to 4 days. This soup also freezes well for up to 3 months. Allow it to cool completely before transferring to a freezer-safe container. When reheating, thaw overnight in the refrigerator and warm on the stove over low heat. Note that the texture may slightly change due to the coconut milk.
Q: What if my soup is too thick or too thin?
A: If the soup is too thick, add a little more vegetable broth or water, one tablespoon at a time, until you reach your desired consistency. If it’s too thin, simmer it uncovered for a few minutes to reduce and thicken the soup.
Q: Can I make this soup vegan or gluten-free?
A: This soup is already vegan as written, using coconut milk instead of dairy. To ensure it’s gluten-free, use gluten-free soy sauce or tamari, as regular soy sauce often contains wheat. Double-check that your miso paste is also gluten-free, as some varieties may include barley.
Q: What are some variations or toppings I can try?
A: You can customize this soup by adding a pinch of cayenne pepper or red pepper flakes for spice. For extra protein, stir in some cooked lentils or chickpeas. Other topping ideas include toasted coconut flakes, chopped cilantro, or a swirl of chili oil for added heat and flavor. If you’re looking for a heartier option, serve the soup with crusty bread or over steamed rice.
