I’ve been in the mood for light soups that will won’t leave me hungry half an hour later. That’s how I came up with this Chunky Mushroom Soup with Buckwheat.
It has some of my favourite ingredients together for a savoury and filling soup we can eat guilt free.
Mushrooms, of course, are a classic ingredient, from Cream of Mushroom to Wild Rice and Mushroom, it is one we keep coming back to for a reason. But buckwheat may be more of a surprise. Stick around, though, because I think you’ll learn to love it!
Why you’ll love it
We know that a soup always goes down well for lunch. But the golden standard for soup is one that can be a substantial meal all on its own.
That’s why I’ve left the ingredients in this soup pretty chunky. Chunky soups take a bit longer to digest, which means we are left satisfied for longer.
Soups made with such a wide range of vegetables and other ingredients also come with additional nutritional benefits. Because each ingredient brings something different, you get a soup that hits lots of notes at the same time.
As well as being substantial, the soup carries an incredible range of ingredients as well. Nutty buckwheat and mushrooms, fresh vegetables and a flavourful broth. Perfect!
Ingredients
It’s hard to say which is the real star of this soup – the mushrooms or the buckwheat. Or perhaps it’s both together?
Buckwheat is having a bit of a revival, and I couldn’t be happier. It’s an ancient grain that has key place in the cuisines in places like Eastern Europe and Japan but was unfortunately forgotten in many other places.
Buckwheat groats are the hulled seeds left whole, and in this recipe I’ve chosen the roasted variety. Buckwheat has a natural nutty flavour that adds depth to anything it touches, making it perfect for a savoury soup.
The soup also has two different types of mushrooms to really let them shine. The dried porcini mushrooms are specially important as they have a concentrated earthy flavour and carry an extra depth.
Using porcini mushrooms with buckwheat means that we’ve leaned hard into savoury, nutty flavours in this soup. The vegetables, and especially kale, are not to be ignored, but the mushrooms and buckwheat are the really stars!
Recipe tips and notes
- Dried porcini add a lot of flavour to this mushroom soup recipe. If possible, do not omit them. If they are unavailable in your local supermarket, look online. They last forever if kept in an airtight container.
- Lots of other mushroom varieties can be used in place of white button mushrooms. Chanterelles, oyster and cremini mushrooms are all good choices.
- I used This is an affiliate link.roasted buckwheat, which is sold in many Eastern European shops as well as online. Roasted buckwheat is brown and has a firmer texture than unroasted buckwheat. It also has a nice nutty flavour.
- You can use lots of other grains in place of buckwheat, such as barley, wild rice, or brown rice. Adjust cooking time according to package instructions.
- Feel free to replace kale with spinach. Frozen spinach will also work.
- I’ve used vegetable stock so that vegans and vegetarians can enjoy this soup, but chicken stock can be used instead.
- To make for a creamier soup, single cream or sour cream can be added when it’s time to serve. Black pepper can be added as well if that is to your taste, and always check to make sure there is enough salt.
Serving suggestions
I’m not a complicated person, so give me a bowl of hot soup with a crusty bread and I have everything I need.
Still, sometimes a sandwich is what’s needed to really round things out. A few that I might suggest:
- Focaccia sandwich
- Chickpea salad sandwich
- Ham and cheese toastie
- Goat cheese sandwich with roasted vegetables
Storage and leftovers
Soups are a great choice for batch cooking, where a large quantity is made and saved for later. I often double soup recipes like this one so I can enjoy some now and freeze the rest for later.
Whether storing in the refrigerator or freezer, let any leftover soup cool to room temperature then place in an airtight container. It’ll store for a week in the fridge and a couple of months in the freezer.
