Lentil Soup Tips

Can you put raw lentils in a slow cooker?

Yes, you can! This recipe is easy: Just add the lentils in and let them cook slowly with the broth.

Do you have to soak lentils before slow-cooking?

No, you can skip soaking! It is a good idea to give the lentils a quick rinse in a strainer, though, just to sift out any dust or dirt.

How do you store lentil soup?

You can store this lentil soup in the fridge for several days. If you can't finish it that quickly, it's easy to freeze. Let the soup cool, then put it in the container of your choice and freeze. Use within six months. Because this soup is so easy to keep, it's great to make ahead of time.
