Slow Cooker Lentil Soup Recipe

slow cooker lentil soup with a loaf of bread

I’m not sure where you live. We’re in Alabama. And if it dips below 50 degrees it’s full-on winter warning mode for me. And that means soup!

I am a huge fan of soups, stews, and chowders. Actually, if it has all sorts of things in it, and it can go in a bowl, sign me up.

What’s nice about this particular soup is that it is extremely good for you AND it doesn’t taste like wet cardboard. You get all the health benefits AND the flavor. Sometimes that’s hard to find.

As our daughter is a lazy vegetarian (she eats fish and shrimp sometimes) we decided to make this soup in a way that she can enjoy as well. We boosted the flavor by adding some baby bella mushrooms that gave the soup a nice earthiness and depth of flavor to it.

The soup itself contains all the aromatics of onion, carrot, and celery one would expect in a soup. The cumin adds a nice smokiness. The bay leaf and thyme add additional layers of flavor and the tomatoes add the acidic richness that bring it home.

But the real star of this soup is the lentil. Lentils is kind of a superfood.

It comes packed with tons of protein and fiber which means you’re going to fuel up and get some good gut health benefits. The potassium counteracts the damaging effects of sodium. The folate helps in red blood cell formation.

What does all this mean? Well, let’s sum up: We’re talking about a dish that will fill you up, help lower blood cholesterol levels, adds protection against colon cancer and type 2 diabetes.

It also aids in lowering your blood pressure, aids in preventing anemia, and may help in preventing heart disease, cancer, and dementia. LENTILS!

Did I mention that it tastes delicious and is waist friendly AND uses the slow cooker so you can just dump it and forget it?

How To Make Slow Cooker Lentil Soup

This soup comes together pretty quickly. It’s about just getting your vegetables prepped.

Ingredients for lentil soup

Dice the onion, carrots, celery stalks, and slice the Baby Bella mushrooms. Finely dice the garlic.

Add all that to the slow cooker. Add the lentils, vegetable broth, diced tomatoes, salt, pepper, and cumin to the slow cooker and stir.

Lentil soup ingredients in a slow cooker

Set the crock pot to low and allow to cook until the vegetables are tender, but not falling apart, about 7 1/2 hours.

To optionally thicken the soup a bit more, which we did, remove two cups of soup and add to a blender, and hit pulse a few times to slightly puree it. Then add it back to the slow cooker. If you have an immersion blender, you can use that by running it for a few seconds.

Next, add the spinach and set the slow cooker to high for 30 more minutes. The spinach will wilt down and add a great texture to your soup.

After 30 minutes, turn off the slow cooker and serve. Season with salt and pepper to taste and enjoy!

Questions

Why green lentils over red lentils? Green lentils will hold their shape over the long cook. Red lentils will disintegrate with prolonged cooking.

Can I freeze the lentil soup? Sure can, it’ll keep like anything else for a few months. We’re sending our daughter back to school with some.

What are the leftovers like? Amazing. Like any other homemade soup or stew, the next day it almost seems to taste better as it’s had time to really have all the flavors come together. I found no need to add additional water or vegetable stock due to absorption.

Conclusion

Lentil soup with bread

I love this soup! It has a great depth of flavor. The mushrooms add a great earthiness, the cumin comes out giving it a slightly smoky taste.

I normally don’t go in for vegetarian soups as, for me, they lack a richness. Sometimes it can be thin tasting.

Not this soup. I didn’t miss anything.

All the health benefits of this soup, plus it being low cal, and tasting the way it does … well, I’ll be eating this going forward. Probably every week I will be enjoying this. It’s that good.

Lentil soup with cornbread

I actually had mine with some freshly made cornbread. Holy smokes, dipping that cornbread in the soup was a crazy delicious bite.

This is a great recipe. Absolutely you can serve this as a meal for the family. Throw in the cornbread or some freshly baked bread and you are good to go!
