You guys. This soup. Is Amazing.
And it’s not because I made it OR because I love soup. Although both are true.
It’s because it contains lentils and NO ONE PERSON AT THE TABLE NOTICED!
Even my picked eater had two servings, and that my friends, is practically unheard of. And a miracle.
This soup tastes just like the weather outside right now – cool crisp mornings with warm-yet-be-prepared-for-hot afternoons. It’s like fall is here, but summer isn’t ready to leave yet.
In a bowl.
It’s also officially my favorite soup of all time. Partly because it’s SO stinkin’ good, but also because of the aforementioned lentils.
Feeding my family beans and legumes – without getting complaints in return – is a tall order. But I haven’t given up or anything. Cheesey Mexi Lentil Macaroni is one of the kids favorites (probably because it tastes similar to a Mexican-style cheeseburger helper), and the two variety of beans in Tortilla Soup go over well too.
But’s a stalemate for most recipes beyond that. It’s not really that much fun to cook dinner and get questions like “does it have beans?” or “is this a bean?” or “why are there so many beans?” at the table.
Knowing these questions will come, I dread cooking. Then that dread follows me from the kitchen to the table and dinner becomes a chore rather than quality time as a family. And then…
Red lentils entered my life and the gates of bean dread suddenly disappeared. Because this SUPER cool thing happens when you cook red lentils: They disappear.
For real! When they’re fully cooked, red lentils sorta kinda disintegrate into the soup itself, leaving behind a creamy, oh so tasty puree in it’s wake. And when you mix it up with fresh vegetables, homemade chicken stock and a few simple herbs? It becomes the tastiest bowl of goodness you could possibly imagine.
And no one even knows it has lentils!!
In retrospect, I should have named this recipe “Lentil Soup for Those Who Hate Lentils.” Because that’s what it is. I asked Mr. Crumbs (my picky eater) if we could add this soup into our soup rotation and he said yes. Right after he helped himself to a second bowl!
You need to make this soup. Right now. Because chances are your family doesn’t like beans and legumes all that much, but they’re also a powerhouse of nutrition and super cheap. (Bob’s Red Mill is the most affordable at 18¢ per ounce, which literally getting the best quality for the best price.)
And because the days of approaching fall meets waning summer will end soon.
But it’s okay. Because this soup will be just as delicious in the dead of winter too. Or even in the spring, for that matter.
Shoot. Just go make the soup. And make a double batch while you’re chopping so you have a quick and easy dinner later on (see notes below for tips).
Then immediately add it to your recipe rotation. Yes, it’s that good!

Additional Recipe Notes
As if the fact that YOU’RE FEEDING YOUR FAMILY LENTILS AND THEY’RE NOT COMPLAINING isn’t awesome enough as it is, this meal can be made in the slow cooker OR even frozen for a super-quick meal later on:
- Slow Coooker Version: Dump all ingredients in the slow cooker and cook on low for 6-8 hours, or until the lentils are cooked through and very soft.
- Freezer Meal Version: Dump all ingredients raw into a gallon-sized freezer-safe bag. Lay flat and press the air out. Freeze horizontally, then stack vertically to safe freezer space. To prepare, dump contents into a large pot OR a slow cooker and cook according to directions.
Adding 2 cups of shredded chicken makes this a non-vegetarian meal (if you need to appease the meat and potato folks in the family), but my favorite version (and the most frugal option) is to serve over hot rice. Although if you happen to have leftover noodles or other grains in the fridge, feel free to serve them with this soup!
If you don’t have all the vegetables in this recipe, no worries – substitute with whatever you happened to have on hand. Add zucchini if it’s summer, butternut squash in the fall, sweet potato in the winter and asparagus in the summer. Seriously, add whatever you have because it’s really the red lentils that makes this recipe rock!

This my friends, makes a big pot of soup. You’ll get leftovers for at least one or two lunches, but this recipe is PERFECT for hosting company.
Add some freshly baked bread (Man Bread, Rosemary Olive Oil Bread or even No-knead Artisan Bread would be great), with butter and you’ve got a meal. You could even add those 2 cups of chicken if you had it too, but don’t stress out if you don’t. This Red Lentil Vegetable Soup is awesome enough without it!

Disclosure: This post is sponsored by Bob’s Red Mill. I love Bob’s Red Mill products and used them often in my kitchen, long before this blog was born. As always, I would never recommend anything on Crumbs that I wouldn’t recommend to a close friend or neighbor, and all opinions here are my own.
MMMMMmmm… my house smells like a really good restaurant right now!! Your soup is on my stove and its 30 minutes in on the simmer. I just tasted it and it’s perfect!!

I love this!!! I hope y’all like this as much as we do!
What about directions for the Instant Pot
I haven’t made this in the instant pot yet Stephanie, but if you do, please let us know how it turns out!
i was wondering how many servings does this yield and what is a serving size?
Hi Catherine! I’m awful at serving sizes, so here’s my best explanation: If each ladle was about 1/2 cup (ish), you could get 4 people dinner plus maybe another 2 servings. My standard rule of thumb is that if a soup calls for 4 cups of liquid, it’s enough for dinner for 4 & needs a side (bread/salad). If it calls for 8 cups of liquid, it’s a full dinner w/leftovers for lunch. 🙂
Do you have any suggestions for using red SPLIT lentils? That is all I could find.
I think that’s the same thing Morgan. They look like they’re split in the bag, so I’m thinking it’s just a different naming convention. My suggestion – make this soup! 🙂
It looks delicious! I’ve never seen red lentils here, but I’ll try it with regular lentils, which I love.
So is there a big difference in the red lentils vs other colors? I have some green/brown lentils that I use on occasion in soups. Assuming they would work as well. Sounds like a new soup to add to OUR rotation along with that famous man bread, lol!
Melissa, they’re slightly different. The red ones cook faster (15 min) and once they’re done, they break down into a puree. You can sub other lentils if you have them, but you might actually SEE them in the final soup rather than end up with a puree. But if your family doesn’t care, then go for it – this soup is awesome!
Okay! Thanks!
Which is why the slow-cooker option is really silly. This soup cooks up so fast, it’s ridiculous. The rice would take the longest. How to make this an even speedier dinner? Use rice you’d made (and doubled the amount you needed) the day or two before for another dish. Bam! Dinner in nearly an instant!
A perfect fall soup! I can’t wait to try this satisfying recipe!

I hope you enjoy it Sommer!
Your pictures look amazing! I love the suggestion of pairing with homemade bread. I love making bread but we’ve been trying to lay low on the carbs–having the soup with a little bit of bread seems like a nice trade off 🙂 I have some lentils in my pantry that I haven’t touched because I have never cooked with them before. Thanks for the great recipe. I will be trying it this weekend!
Thank you Crystal! This is a great intro recipe for lentils – enjoy!!!
