Last week we made our Coconut Lentil Curry Soup and I had some leftover lentils so wanted to use them up. I used to go to this restaurant back in the day that served up an awesome lentil soup. I haven’t made it in years so decided to break out the slow cooker and toss in some extra vegetables, too. This veggie packed lentil soup turned out great and will now be added to our rotation for soups during the cooler months.

Frequently asked questions:

Can I use a different broth?

We used low sodium vegetable broth. But yes you could use chicken or even beef broth if that is what you have on hand.

Can I make this lentil soup on the stove top?

Yes, absolutely. You would need to sauté the onions, carrots, mushrooms, and peppers first. Then add in the broth, potatoes, and seasonings. Bring to a boil and then let simmer until the veggies are tender.
