Slow Cooker Lentil Soup Recipe

This slow cooker lentil soup recipe is perfect for a chilly evening at home!

I’ve done several lentil soup recipes. For me, there is something very comforting about lentils. They feel homey and nurturing. Even more so when they come out of the slow cooker like this clean eating slow cooker lentil soup.

I like this recipe simply for it’s ease. You can’t get much simpler than using a slow cooker. Plus, it’s a wonderful Meatless Monday dish to come home to after your first day back at work for the week.

It makes enough to freeze some for a few future meals and freezes really well too. I like to make some for dinner and pack the rest away in the freezer for quick and easy, grab-n-go lunches. I take it straight from the freezer and by the time I get to lunch, it’s mostly thawed. And if not, a quick few moments in the microwave or in a pot on the stovetop gets the job done.

Give it a try! It’s a great way to stock your freezer for the cold months!

      Lori – My pleasure! So happy you enjoyed it! 🙂

  2. Could I use already cooked lentils from Trader Joe’s?? Maybe lessen the cook time?

    1. The Gracious Pantry says:

      Andrea – Yes. I haven’t tried it, but here’s what I would do. Use 4 cups broth instead of 8 and try 2 hours on low. You may have to adjust the cooking time for the carrots. But if you slice them thin, 2 hours should be plenty. Let me know how it turns out! 🙂
