Slow Cooker Lentil Soup

Soups, stews, chowders and the like are on my go to list of things to make when we are tired of "regular meals". You know, like pork chops with green beans, steak and potatoes, pizza and etc. Ok... well it takes a bit for me to get sick of pizza.

I have a recipe arsenal loaded with soup recipes like this hearty slow cooker lentil soup. This version was made on one of those "use up what we have, I need to do groceries" days.  Since then I have made slightly different versions, but the broth and lentils are always the same.  Have fun and experiment with your own versions too.

Does it Matter What Type of Lentil I Use? 

I prefer green lentils as they hold their shape better, and for me, that is appealing.  Others, however, prefer the split red or yellow lentils in soups as they soften and become a bit mushier.

For this recipe, use a brown or green lentil if you prefer it to hold it's shape.  Use a red or yellow lentil if you prefer a more mushy or pureed soup.

Variations of Lentil Kale Soup Recipe

While the base is always the same, you can definitely mix things up a bit to add more flavor or a different flavor to this easy slow cooker soup recipe.  Below are some simple changes to the recipe that can add a unique spin on a classic.

  • Use andouille sausage instead of chicken sausage.
  • Add diced carrots for more fiber.
  • Use RoTel tomatoes instead of diced tomatoes for more heat.
  • Substitute the chicken broth with beef broth, vegetable broth, or tomato juice.
  • Use red or yellow lentils instead of green.
  • Switch out spinach in place of the kale.

Can This Be Vegan? 

Yes! If you are looking for a hearty soup that is also easy to make into a vegan dish, this is a perfect choice.  Lentils are a common choice for added protein in vegan dishes, and it really is simple to turn this into a tasty, protein packed soup that is fit for anyone at your table.

To make this lentil sausage kale soup vegan: 

  • Substitute chicken broth for vegetable broth.
  • Use a vegan sausage like Field Roast or Beyond Meat, or skip the sausage and add in a bit of fennel and sage instead.
