Creamy, mild, hearty with delicious pan-fried peanut tempeh, this Creamy Potato Miso Soup is delicious with amazing marinated peanut butter tempeh. And you only need 9 basic ingredients!
Gentle is the first word I would like to describe this Creamy Potato Miso Soup. This soup is one of the things that I improvised and turned out really great.
It’s creamy but not heavy with a mild taste with depth. With the addition of peanut-butter-flavor tempeh, this soup is really satisfying and hearty, perfect for the upcoming winter.
This soup is simple, both ingredient-wise and doing-wise. You only need 9 basic ingredients to make it.
It’s also kind of a dish where a Westerner meets an Asian. There are some common Asian ingredients as well as Western ones. But who says they can’t be together?

Method
How to Make Peanut Tempeh
- Mix peanut butter, soy sauce, maple syrup, water, and garlic powder in a bowl.

- Use a non-stick frying pan to fry the tempeh cubes with some oil.
How to Make Potato Soup
- Stir fry the onion with some oil in a pan over medium heat. Cook until the onion is soft and fragrant.
- Add the chopped potatoes and cook for 30-60 minutes. Then add the water and cook until the potatoes are soft.
- Transfer it into a blender and add miso to blend until smooth.
- Pour the soup into the pot and add dried kelp and cook until soft. Add black pepper water/salt to taste if needed. Finish with a handful of chopped green onions if you feel like it.
- Add the peanut butter tempeh to the soup or enjoy them separately.
Notes
I’m not a person who enjoys heavily salted food so a tablespoon of miso works for me. Yet everyone’s taste bud is different. If you feel it’s underseasoned, don’t hesitate to add more miso or salt to your own taste. Make it work for you. :))

This potato soup is not like common potato soup. It’s creamy but not heavy, mild but not too plain. I didn’t fall for it in the first sip, but I love it after finishing my first bowl.
I hope you will enjoy it as much as I do. If you’re hungry for more, try:
