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.

    This soup has become a staple in our home. Tasty, healthy, easy to put together. Love this recipe! I did not use the green beans only because frozen green beans are not my favorite. Instead, I added 2 cups fresh chopped kale (and 1/2 cup extra carrots) with the first 8 ingredients into the crock pot. A splash red wine at the end with the canned tomatoes. Perfecto!!

    This soup is extra delicious with the Taste Of Home Walnut Balls recipe added in when you add the green beans!

    This is my second time making this soup. I love vegetables, so this soup was right on for me and my family. I added zucchini and lots more dice carrots and some celery too. YUM

    A great recipe and simple to make. I substituted potatoes for the butternut squash and also put the green beans and tomatoes in at the beginning with the rest of the ingredients. It worked out well and it tasted great! I also added about 1/2 tsp salt for taste since none is in the recipe
