Slow Cooker Lentil & Peanut Butter Soup

 Hearty winter soup with gutsy flavours made in the slow cooker.

Lentil and Peanut Butter Soup

SLOW COOKER LENTIL & PEANUT BUTTER SOUP

This is a soup I've had in my mind to make for a while.

I remember making a lentil soup years ago that included peanut butter and I wanted to try and recreate it in the slow cooker.

I don't have that old notebook that I used to scribble my ideas and recipes in, so I had to try and remember the flavour and recreate that and I have to say I think I did pretty well.

It's a gutsy soup with a lot of flavour and it's really filling too.


SLOW COOKER SOUP

Slow cookers are almost made for making soups and stews.

Just chuck all the ingredients in and get on with your day.

Of course, you have to remember to reduce the liquids in a slow cooker recipe as the liquid won't reduce as it does when you cook soup in a pot.

For the best slow cooker soup and this is true of all soups, make it one day, cool it in another container, chill and eat it on day two if you can. 

Soup always tastes better on day two.

RED LENTILS

I use red lentils a lot in my cooking. 

I add them to soups, like my fridge lentil soup, I add them to pies, like my red lentil shepherd's pie and I make the most heavenly spinach and coconut dal with them.

They are a great staple to keep stocked up.

The best thing about them is they don't need any soaking or pre-cooking, you just throw them in.

They add flavour to soup as well as making them lovely and thick. 

They also add protein to your soup.

HOW LONG DOES SOUP COOK IN A SLOW COOKER?

This soup can be cooked on low for a long cook or high for a faster cook, although still a slow cook.

If you cook it on high, cook it for 4 hours.

If you cook it on low, cook it for 8 hours.


DON'T OPEN THE LID!

Please leave the soup alone!

Don't be tempted to open the lid while it's cooking.

If you open the lid, you reduce the temperature and you allow water to pour in from the lid which will just make your soup watery.

Don't do it!

HOW LONG WITH LENTIL & PEANUT BUTTER SOUP KEEP?

Add it to an airtight container and keep in the fridge for 3-4 days.

    1. Saute the onion and garlic until soft then add the other ingredients. You'll need more stock or hot water (probably about a third), just add it if you think it's getting too thick. Cook for about 30 minutes.
