Stay warm with this healthy slow cooker lentil and vegetable soup recipe. It’s one of those amazing set-it-and-forget-it recipes and is great for making for healthy meals to take for lunch throughout the week!

The most delicious healthy slow cooker lentil and vegetable soup this image
During the holidays, I like to take a little break after posting the top recipes of the previous year (see here for 2017 top reader favorite recipe, 2018 favorite recipes and 2019 favorites). I like to shut down my computer and only check email via phone, occasionally.

It is really great and relaxing…but then one year when I was pregnant with my first child (I now have three kids, boy/girl twins and a toddler) I got a head cold for 5 days. And of course, being pregnant I couldn’t take any medications. So I relied on healthy healing soups, including this lentil soup (I swear this lentil soup cured me!)

The best ever slow cooker vegetable and lentil soup This 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.

A few years ago 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 our 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.

The best recipe for slow cooker lentil and vegetable soupThe 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?

The most amazing 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 healthy gluten free soup is the end result.

The best slow cooker soup recipe Because 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 down and become soft and stir in beautifully with the other veggies for a delicious soup! You can definitely use other lentils, but they might not cook down like red ones do, still delicious, just not as thick in texture.

If you love this recipe, two other vegetarian soup recipes you might enjoy are this vegan red lentil chili and this 5 ingredient tomato white bean soup recipe.

      Yes, I would double everything. I would like to add though that you might need a giant slow cooker – or nesco if doubling this recipe because it really fills a slow cooker 🙂

    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 ?

    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!

    I was concerned it wouldn’t be flavorful enough and boy was I wrong.

          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 🙂

    Wow! Your recipe elevated me to Rockstar status with one meal. During the last couple of weeks I put a lot of good dinners on the table that were enjoyed, but this was the first one that was so healthy – and fully vegetarian.

    It turned out extremely well and was appreciated by everyone.

    I’ll definitely be making it again and look forward to checking out more of your recipes.

    Thanks again!

    This looks fantastic and I know my wife will be excited with all of the healthy ingredients. I am a born-again chef (ordering pizza was my previous idea of making dinner) and just learning my way around the kitchen.

    Since I am so new at this, the prep work took me an extra hour but I’m sure I will be much quicker as I gain experience.

    I have 4 1/2 hours left to experience the magical combination of the slow cooker and this recipe. I will let you know how it turns out!

    This might be a silly question, but are you supposed to cut the vegetables before adding them to the pot? Or do you leave them whole and they get soft and mushy and mixed into the soup by the time they’re done?

      Hi. I’m confused about the 8 hours cook time vs. 8 hours 15 minutes inactive time. What is inactive time? Also, do you think I can keep the soup in the slow cooker for 24 hours since that suits my schedule best on some days?

      Reply
      • Sweetphi says

        June 29, 2020 at 8:18 pm

        Hi – sorry about the confusion. Inactive time is time you’re not doing anything. The cook time is 8 hrs. I’ve never had anything in the slow cooker that long, so I wouldn’t know if it would work or not, if it does work for you, I’d love to know. Enjoy.
