Slow Cooker Lentil Soup Recipe

We have the perfect recipe to try for Meatless Monday or any day of the week! Slow Cooker Lentil Soup Recipe is so hearty and delicious that no one will ever miss the meat.

The tomatoes give it the best flavor and the lentils are so tender. Even better, the crockpot does all the work making dinner time a breeze.

This meal is budget friendly and easy to feed a crowd. Serve this amazing soup with warm bread like Easy Homemade Dinner Rolls Recipe  and you can’t go wrong.

The bread is perfect for dipping into the lentil soup and getting every last drop. Yum! It is so good.

Can you make lentil soup in a slow cooker?

Absolutely! It is my favorite way to make lentils because the slow cooker does all the work.

Simply toss everything in the crockpot and come home to dinner waiting. I like to start the soup in the morning and then after a long day of work and activities, dinner is ready for us.

Do you have to soak lentils before slow cooking?

No you do not. Just toss the lentils and all of the other ingredients into the crockpot.

This recipe is so easy. You literally just toss and go.

How long do lentils take in slow cooker?

We cook this soup on low for 7-8 hours. You can also cook on high for 5 hours.  

You need a good crockpot for this slow cooker soup.

There are some really good ones on sale right now. If you work all day, you may want to invest in a programmable crock pot.

They are awesome because you can set them to start later, or to stop and switch to warm once the dinners are ready. Amazon has some on sale right now too.

I also really like this crockpot.  Now, it’s not programmable but it’s so handy!

It has the feature where you can lock the lid down.

That feature is so nice for when you take meals to potlucks or need to transport the meal somewhere.

Now if you want to save yourself even more time then I really recommend these Crockpot liners. They make clean up a breeze.

Instead of scrubbing and washing the pot, you can just toss the liner. It is practically no clean up.

If you are short on time, this recipe can easily be adjusted for the instant pot.

Tip for low carb slow cooker lentil soup:

This recipe like many calls for diced onions. Another time saving tip is to use a small food chopper or food processor to quickly and easily chop the onions.

If you do not have one of these, I highly recommend them. They are such a time saver and you can get the veggies really fine if you have children that are picky.

I usually just chop the entire vegetable and freeze what I don’t need. It’s so nice to be able to just take the diced onion out of the freezer for recipes.

This is how I meal prep. It’s so quick and easy and helps get dinner on the table fast.

Learn and  how to freeze onions and also how to freeze peppers to save so much time in the kitchen!

Sometimes, I saute the onion in a little olive oil before putting in the crockpot but that is optional.
