Easy Crockpot Vegetable Lentil Soup Recipe
Lentil Soup starts to sound extra delicious to me as soon as the fall season approaches. The absolute best way to make lentil soup is in the slow cooker. This Easy Crockpot Vegetable Lentil Soup Recipe has been a family favorite ever since Big D was a baby. The soft veggies were perfect finger foods for her little fingers. Ahhh the memories 🙂
Now that my girls are getting older, they ask for this soup all the time. And I am MORE than happy to make this veggie packed soup for them.

I followed the recipe and cooked on low for 8 hours and the lentils were still hard. What do you think I did wrong?
Where they just firm, or still hard like they feel when they are try? Lentils are meant to be a little firm. Mushy lentils are no fun 🙂
Looking at this for a lunch at work. How many does it serve? If i missed previous answer, sorry.
great recipe! Last time I made it I had to cook additional and add about 2+c of water, on the stove using the pressure cooker (15 minutes and it came out GREAT!). Trying in the crock pot on high this time, reduced lentils to 3c, I like it thick but it was a little too “goopy” with 4c. I also use 2 sweet potatoes, no other potato, and only 1/2 onion and 2 garlic cloves- makes it a bit more appetizing smell than the full onion and 4 garlic cloves. I love the idea to add ACV- think I’ll do that, too! As to serving, last time I made it we served about 12 bowls- AT LEAST! As it sat for a day or 2 we added more liquid as the lentils absorbed.
Is it harmful to omit the potato?
I don’t think if would be Candice 🙂
Like many of the comments before, 2-3 cups of lentils is plenty for this recipe. It’s pretty dry and not really a soup with 4 cups of lentils. The flavor is great though!
