Small Batch Sweet Potato Miso Soup
This Sweet Potato Miso Soup is our twist on the Japanese classic! We have taken the original sweet and savory soup traditionally served with bonito and kombu dashi to use central and south American sweet potatoes instead of Japanese sweet potatoes.
This swap makes the recipe more accessible if you don’t have access to Japanese sweet potatoes at your grocery store. This savory healthy soup is perfect for soup season, and it’s also a great way to add more of these nutritious root vegetables into your diet with unique flavors and simple ingredients.
Why This Recipe Works
This Sweet Potato Miso Soup is vegan and uses just a few ingredients but the flavors are very comforting, mixing a lot of savory, naturally sweet, and umami undertones for a very simple but delicious soup to add to your fall rotation.
If you aren’t familiar with miso, let us introduce you. Miso is a traditional Japanese seasoning made from fermented soybeans, which gives it that earthy flavor, salty, and sweet taste. We’ve paired that with sweet potatoes which are rich in beta carotene which can convert to vitamin A in our bodies. Vitamin A is an important micronutrient because it helps maintain vision, healthy skin, and can protect against infection, making sweet potatoes a great ingredient to add to this delicious soup.

Ingredient Notes
Miso Paste: Miso Paste might be the only ingredient that can sometimes be hard to find depending on what part of the world you live in. We typically find this at our local Asian Market, Trader Joes, or Wegmans. You can also order miso paste on Amazon if you can’t find it in your local grocery store. There are different types of miso but we suggest yellow or white miso for this recipe.
Which Type of Miso Paste Should You Choose?
This is up to you! Yellow miso paste is fermented for a longer time than white miso. Yellow miso paste is considered saltier and more acidic while white miso paste is considered more multipurpose to flavor. We suggest going with white miso paste if you are new to this flavor.
