Buckwheat Mushroom Soup Recipe

With no specific origin, the buckwheat mushroom is popular in most Eastern European countries. 

The soup included veggies and fresh mushrooms that we collected from the forest. Rich and creamy, buckwheat mushroom soup was a welcome difference from the simplicity of porridge, and we enjoyed it both as a snack or as a meal. 

What Is Buckwheat?

Buckwheat or kasza gryczana in the Polish language is a plant that produces seeds that look like grains. Despite its name, it does not belong to the wheat family and is a pseudocereal.

The common version of buckwheat in Europe is fagopyrum esculentum, but other versions such as fagopyrum tataricum or green buckwheat are also eaten.

The buckwheat plant is often considered a superfood because it’s nutritious, full of fiber and protein, and has many health benefits. Plus, it’s good for weight loss!

How To Make Buckwheat Mushroom Soup 

Cook the buckwheat with dried soup veggies in broth or water till soft. Broth adds more flavor than water. You can use this leftover chicken broth recipe, but if you don’t have broth at home, you can use any store-bought broth.

While the broth is cooking, dice an onion. Then, slice the mushrooms and fry them in butter.
