This spicy lentil kale soup is hearty, delicious and pretty budget friendly. Made in one pot for easy cleanup, it’s like a little bowl of goodness for your tummy!

This soup was made for Monday. Monday gets a bad rap sometimes. But, think about it. If there wasn’t a Monday, then Friday wouldn’t be so special. Monday is taking one for the team. And if Monday wasn’t a thing, would Tuesday be the new Monday? This is too much for today.
This spicy lentil soup is totally on the healthier side so it helps wipe away any weekend indulgences โฆ that’s what I tell myself at least.
Totally ate too much this past weekend. Fries? Yes, please! Bacon and eggs? Sure! You had that extra glass of wine. Why not?
You had a busy week. You don’t even want to look at those skinny jeans Monday morning; it’s not gonna happen. No worries, fill yourself with this goodness, and get yourself set for an awesome week!
In my opinion, it’s all about balance. If you can’t indulge every once it a while (especially on the weekend), then that’s no fun at all. A little indulgence here, a little healthier there. Nothing complicated, just like this lentil and kale soup.

Why We Love Spicy Lentil Kale Soup
- It tastes delicious!
- This soup is loaded with veggies, like kale, which adds flavour and heartiness.
- It’s pretty budget friendly with simple pantry staples, like red lentils.
- Uses ingredients that you probably already have on hand.
- It’s made in one pot for easy cleanup.

What To Serve with Soup
- Grilled cheese sandwich
- Simple green salad
- Crusty bread for dunking
- Croutons (delicious over top of the soup)

I don’t know about you, but I could eat soup all year long, even in the summer. And it’s weird because I like to say I run hot. Like, I’m usually always warm. But, offered a bowl of comforting soup and I’m all in. Hope you love this lentil soup as much as we do! It’s great on a cold day!

I like both lentils and kale, but I don’t think I’ve ever combined them in one dish. I’ve never tried kale soup either. This is something that I absolutely need to try!
Girl Heart Food
So good, Ben! Nice and hearty for sure ๐

Girl Heart Food
Thanks Dana! Kale really adds a lovely heartiness, doesn’t it?

Shashi at SavorySpin
Hahaha – I’ve gotta agree with you, Dawn – Monday sure does get a bad rap – but (like you said) if there wasn’t a Monday, Friday wouldnโt be special at all! So yes to Monday is taking one for the team … and I don’t wanna think of Tuesday being the new Monday – I’d rather drown in a big bowl of THIS soup! Going through your ingredients, this sounds so delicious and so comforting (lentils were comfort food for me growing up) – a bowl of this and some chunky bread and I’m a happy camper!
Hoping you are doing well and your week is off to a wonderful start! XOXO
Girl Heart Food
Definitely ๐ Yes! Chunky bread and this would be total comfort food! Have a wonderful week, my friend! XOXO
Milena
I dig lentils anything, so this soup is happening, We are having issues with the weather, it is all confused as to what to do…right now seems like not wanting to let winter go away so your soup, especially with the heat element:) sounds perfect! I am the opposite of you, I always run cold, lol.
Girl Heart Food
Woo hoo! Happy to hear that! And I hear ya about the weather – super cold and windy here today and absolutely no sign of spring. A good bowl of soup is in order ๐ Thanks Milena!
David @ Spiced
It’s still quite chilly here, so a good bowl of soup sounds amazing right now! Love the flavors you’ve got going on here, Dawn…I really should use lentils more often. And I hear ya about Mondays. You’re right that we shouldn’t look down on them too much though. After all, they serve the purpose of making Fridays amazing! We’ve gone back to counting calories lately (to get the extra Christmas cookies off before we head on vacation..haha), so a meal like this would make my calorie app very happy! I’m all about big flavor in my soups, too. Yum! Happy Monday, my friend!
Girl Heart Food
Chilly here too and so windy today!! Thanks David! Hope you get a chance to try this one out (and I hear ya about the Christmas cookies). Have a great week!
annie@ciaochowbambina
