How do you make Mushroom Soup in your Slow Cooker from scratch?

To make mushroom soup in your Slow Cooker we add all of our ingredients, then set and forget! 

You can use fresh button mushrooms in the soup. If so, you are going to need to slice them 1st. 

Slow Cooking soup gives you your time back, set and forget whilst your dinner cooks itself. 

Once our soup is cooked, we blitz it slightly to combine but also leave great texture, then add the cream in.  

Slow Cooker Mushroom Soup ingredients

The ingredients you need for this recipe are all easy to find at the local store. They are set out in the photo below:

As you can see we need:

  • mushrooms (I use pre sliced mushrooms)
  • cream
  • vegetable stock
  • garlic
  • thyme
  • bay leaves 
  • dried onion (saves time peeling one!) 
  • salt and pepper

Thick soup or thin soup? I will go into it in a bit more detail below, but if you want super thick soup, you will also need 2 tbs of corn flour. 

This easy mushroom soup recipe is vegetarian, healthy and smells amazing as it pretty much cooks itself!

This soup is LOADED with mushrooms and it has a ton of garlic in it to! 

We add a little cream at the end to make it a a creamy, herby, garlicky, delicious flavoured soup and options to add parmesan cheese, cracked pepper and parsley to garnish! 

Our handy Slow Cooker let’s us do ‘hands free’ cooking and we grab our immersion blender to half blitz it at the end to combine.

One the soup is cooked (2 hours high), you can remove the lid and let it cool down a little. 

The next step we are taking is to blend some of the ingredients and this is easier when they have cooled a little. 

Blending only half of the ingredients leave us with a soup that has great texture from the remaining unblitxed ingredients! 

BEST EVER Mushroom Soup

Is soup really soup if there is no bread to dunk in it? Nah, I don’t think so either. 

My favourite for this soup is toasting Turkish bread in the oven (with a little spray oil) till golden. I find it makes the perfect soup dunking bread.

Once the soup is cooked, you have a few serving options. Try a sprinkle of cracked pepper, some freshly chopped parsley and toasted bread for dunking and a little parmesan cheese!

Slow Cooker Pro tips:

These additional tips are so that you can master Pumpkin Soup in your Slow Cooker from scratch:

  • buy sliced mushrooms as then there is no ‘hard-work’ required at all
  • don’t take the lid off the Slow Cooker for at least 2 hrs (high), 4 hrs (low)
  • allow the soup to cool down a little or somewhat before blending
  • the ingredients will sit just above the level of stock. They will shrink down into it when cooking, however

Can I freeze Mushroom Soup?

Yes! This is a perfect recipe to freeze. 

Allow the soup to cool and then portion it out into zip lock bags. Seal, then lay flat in the freezer. To defrost simply remove from the freeze, allow to naturally defrost and reheat for 3-4 mins until fully warmed through.

Toasted turkish bread is my favourite for dunking in soups! Spray a little with cooking oil and toast in the oven for dunking into your soup! 

The texture of the soup is made through not blitzing the entire batch. We keep some of the ingredients combined but still unblitzed to create a texture sensation when eating!

Notes

  • Note 1 I use sliced mushrooms as it makes it so convenient and quick to prepare the soup. You can use sliced or purchase button mushrooms and slice them with a knife or mandolin
  • Note 2 Homemade stock, packaged stock or stock cubes mixed with water are all fine for this recipe. 
  • Note 3 I love using dried onion! It is a total time saver and saves having to peel and slice an onion. The flavour is exactly the same and the flakes re hydrate to give texture. This product can be found with the spices at the supermarket
  • Note 4 Can use fresh or dried for the thyme. 
  • Note 5 For some people, this soup will be the perfect texture as it is. Some other people will want their soup to be a bit thicker. To thicken this soup, after half blitzing, remove 1/2 cup of the liquid. Add 1 - 2 tablespoons cornflour to that liquid and stir to combine. Once combine pour this ('slurry') back into the slow cooker and stir through. Leave on low for 15 mins then stir again.

Mushroom soup is one of my favourite comfort foods, as my mum used to make it when I was sick as a kid. I am going to have to try making this.
