Slow cooker lentil and vegetable soup , the perfect healthy make ahead lunch!Welcome to 2017. How were your holidays? I took a much needed break over the holidays, after posting the reader favorite recipes from 2016, I shut down my computer and only checked email via phone, occasionally. It was really great and relaxing…until I got a head cold for 5 days. And of course, being preggo I can’t take any medications. So I relied on soups, including this lentil soup (and I swear it cured me!)

Vegetables for slow cooker lentil soupThis lentil and vegetable soup is packed full of veggies. It’s so comforting! And whenever I’m talking about comforting meals and dishes, I always think of the South. Last year I got to tour behind the scenes at Southern Living Magazine, an event that was cosponsored by Delta Faucet. It just so happened to be a coincidence that the faucet in my kitchen was leaky. As I toured the Southern Living studios I was in awe of all their amazing faucets- they were all Delta Faucet and the ones that one just touches and the water comes on/off. When I got my very own Touch2O Technology faucet from Delta, I was beyond happy and grateful.

Cleaning vegetablesThe faucet makes washing everything so easy! When I was cleaning and prepping the veggies for this soup, it took me a fraction of the time because I was able to use the pull down handle, and turn it on/off with my arm. It’s the little things, right?

Red lentil and vegetable soup made in the slowcookerWith the start of the new year, there’s always a desire for healthier recipes, and healthy slow cooker recipes are some of my faves. When it comes to soups, I have to admit that I’m not much of a brothy soup type of person. I like a more heartier soup (like this slow cooker beef and sweet potato stew) – a soup where you can just put ingredients into a slow cooker and it comes out great. This lentil and vegetable soup does just that. It goes into the slow cooker, does it’s cooking, and voila, a delicious soup is the end result.

Healthy slow cooker lentil and vegetable soup recipeBecause this soup uses red lentils, the texture is nice and thick at the end, almost creamy. Sometimes to get a thicker soup, recipes call for putting the soup in a blender. Not with this soup! The red lentils cook and become soft and stir in beautifully with the other veggies for a delicious soup!

    This was incredible! I made this with sweet potatoes vs russet potatoes only because that’s what I had on hand. My husband and I loved it!! This recipe is a must try!
    I was concerned it wouldn’t be flavorful enough and boy was I wrong.

    • Sweetphi

      Oh my goodness, thank you so much for your wonderful feedback. I’m so happy to hear that you loved this soup as much as I do 🙂

      • Melinda

        Don’t have red lentils but just regular. How can I adjust this recipe to use what I have on hand?

        • Sweetphi

          You can cook it the same way, just note that green lentils won’t break down as much as red ones. I’d suggest cooking it on low in the slow cooker for 8 hours 🙂

  • Samantha

    1 hour left in the cook time and my home is smelling amazing!! Can’t wait to dig in and try. Very easy recipe to follow and make, 15 easy minutes of prep and then vegging out in front of the tv while the tantalizing smells start tingling in my nose. Yum!

    • Sweetphi

      Oh my goodness, thank you so much for your amazing comment, hope you love it as much as everyone does 🙂

  • Sara

    Do you use dry lentils or hydrated lentils in this recipe?

    • Sweetphi

      I use dry lentils in this recipe 🙂

    I made this soup, and I cooked it on high for 2 hours, and on low for 4 hours. It was still pretty brothy, so I turned it up on high again, and cooked it for 2 more hours. It didn’t quite look like yours. So, I used an emulsion blender to get that thick consistency. The stew is really good though! I didn’t have jalapeño, or celery, so I added one zucchini to my stew, and it was really good! I’m just wondering why my lentils didn’t break down very much. I also left my potatoes unpeeled, to keep nutrients intact. I’m wondering if that had something to do with it as well. Anyway, awesome recipe, and thank you!

      Hi there, I know zucchinis can be very watery, so that may have contributed to it being brothy – but as to why the lentils didn’t cook down, that I’ve never had happen. Did you use red lentils? Red lentils vs. other kinds (green/brown/etc.) break down and cook a lot faster so that could have something to do with it. Regardless, so glad you liked the soup!

  • Krista

    Any advice for making this in an Instant Pot pressure cooker? How long does it take? Looks super tasty.

    • Sweetphi

      Oh great question! Unfortunately I have never used an instant pot, it’s definitely on my christmas list though, so i’ll hopefully be able to help after that. Sorry!

  • Sarah

    I made this at the weekend & it’s seriously amazing! So easy to make. Thank you 🙂

  • Faye

    I made this today and it was wonderful! I didn’t have a jalapeno so I used a can of diced green chili’s instead and it turned out great. Thanks for a delicious and healthy recipe!!

    • Sweetphi

      So glad you liked this soup! I love the swap of jalapeno for some diced green chilis!

  • Helene

    This was absolutely delicious. Because requested by my kids, I left the kale out and the hot pepper. I also used sweet potatoes instead of russets (what I had on hand). Bookmarked it, will be making it again and again! Thank you for sharing 😊
