This is a quick to prep and very easy vegan tomato lentil soup absolutely bursting with flavor. A weeknight staple that is delish enough to serve for special occasions, too. Most of the work is the lentils simmering away.
Brown lentils are the little black dress of the legume world. They go with everything, take on whatever flavors you throw at them, and in this economy they are a great bang for their buck. I make some version of vegan lentil soup a few times a week and there is almost always a brown lentil situation in the mix.
This one started with a windfall of smoked paprika. It’s one of those spices that can sit empty in the jar for months because I don’t always find it where I shop, so when I got a fresh fragrant bag I wanted to use it in absolutely copious amounts. Add some kalamata olives and a pile of spinach and suddenly you have something that tastes like it took all day. Rich, smoky, flavored like WOW in about an hour with 15 minutes of actual work. It’s also gluten-free if that’s your thing.
The fire-roasted tomatoes go in halfway through, which gives the lentils time to get almost tender first and then finish cooking in the tomato broth. The olives and spinach come in at the very end so that the olives stay nice and firm and the spinach doesn’t wilt into oblivion. Serve it with a crusty baguette and some hummus, or ladle it over polenta if you want to make it a full situation.
Smoky Tomato Lentil Soup FAQ
Can I use a different kind of lentil? Green lentils work great and hold their shape a little better. Red lentils will dissolve and give you a thicker, creamier soup — totally different texture but still good. De puy or black lentils are also fine if you like a sturdy lentil. Just check for doneness since cook times vary.
I can’t find fire-roasted tomatoes. Can I use regular? Yup. Regular crushed or diced tomatoes will work. You lose a little of the smoky depth but the smoked paprika more than carries it.
Can I use hot smoked paprika instead of sweet? For sure, but know that it’s significantly hotter. Start with 1 tablespoon and taste as you go.
Can I add anything to make it more of a meal? Hells yeah. A few people in the comments have added vegan sausage — Field Roast apple sage is a particularly good call with the sweet smoked paprika. Or you can go the homemade sausage route. You could also ladle it over polenta, serve it with a big hunk of crusty bread and hummus, or stir in some cooked pasta or grains at the end.
Can I substitute the spinach? Yup yup yup. Chard works great. Kale would need a few extra minutes to wilt down properly.
Does this freeze well? Better than most soups since lentils hold up well in the freezer. Just add a splash of water or broth when reheating since it thickens up.
How did I end up here? You were probably searching for “vegan lentil soup,” “smoky lentil soup,” or “tomato lentil soup.” This is a simple, deeply flavored plant-based soup that comes together in about an hour with almost no active time. No meat, no dairy, just a really good pot of lentils. You’re in the right place.

Smoky Tomato Lentil Soup With Spinach & Olives
Ingredients
- 1 tablespoon olive oil
- 1 medium yellow onion thinly sliced
- 3 cloves garlic minced
- 1 teaspoon dried thyme
- 2 tablespoons sweet smoked paprika
- 1 cup dried brown lentils or green lentils
- 5 cups vegetable broth
- ½ teaspoon salt
- Fresh black pepper
- 1 24 oz can fire-roasted tomatoes
- 4 cups fresh baby spinach or chopped spinach
- ¾ cup kalamata olives roughly chopped
Instructions
- Preheat a 4-quart soup pot over medium-high heat. Sauté the onion in the oil with a pinch of salt until translucent, about 3 minutes. Add the garlic and sauté for about 15 seconds, then stir in the thyme and paprika.
- Add the lentils, broth, salt, and a few grinds of black pepper. Cover and bring to a boil. Once boiling, lower the heat to medium and cook for 25 minutes, stirring occasionally, until the lentils are almost tender.
- Add the tomatoes, crushing them with your hands as you add them. Bring back to a boil, then lower the heat and simmer for another 20 minutes or so, until the lentils are very tender.
- Add the spinach and olives and stir until the spinach is wilted. Add a splash of water to thin if needed. Taste for salt — the olives are salty so hold off on adding more until after they go in. Let sit for 10 minutes or so for the flavors to settle, then serve.
I have been having Mediterranean eats of my brain all week. I just bought olives, too, and it sounds wonderful with lentils and spinach. I am totally adding this to my menu this week. Thanks Isa! 🙂
now i know what i’m having for dinner tonight, this looks glorious!
can’t wait to try this! all my favorite things!
Boy, have you been busy lately!!! I love it!! This sounds divine…and I know what I need now at the grocery store…Thanks…and keep ’em comin’. This is great!!! AND..I’m getting ready to make that chickpea tofu you told me about. Tuesday, I think….yum.
Oh cool! Let me know how it comes out. (the cp tofu)
this looks amazing. i love soups. loooove the idea of olives in the soup! I’ve never done that.
I can’t wait to make this, tomorrow. All the ingredients were sitting, at the ready, before I even saw this recipe. It was truly meant to be!
Love when that happens!
This looks like a great dinner! I am trying to incorporate more healthy, low cal vegan dishes to my dinner rotation, and this looks great!
I just polished off a big bowl of this for my dinner. I made it with smoked paprika (not sweet) and it was ridiculously awesome… Especially paired with some big hunks of sourdough bread.
Isa, you’re a genius! Every one of your recipes that I’ve tried has been wonderful.
I would love to see a lentil soup recipe that doesn’t call for onions. Sadly, onions just don’t agree with me.
Just leave out the onions.
I make a soup like this, also adding capers and sun dried tomatoes, sometimes also sweet potatoes, mushrooms… finished with balsamic vinegar. I call it Italian Lentil Soup. So yummy!!
Jeannie, leave out the onions if you don’t want them! This is soup… anything goes!
Okay, I broke down and made it tonight instead of tomorrow…and I’m in BLISS. What an amazing soup.
Thank you for giving me a new version on lentil soup! Brown lentils are still my favorite and I could eat lentil soup everyday.
I was just looking for a soup recipe to use some up wilting spinach. I made this for dinner tonight and it’s amazing! So smoky and delicious. Thanks, Isa!
nice dish..lovely staff!
Oh thank you for sharing this magical remedy for the frigid winter dreary greys! It looks superyumful and perfect with a nice dense rustic Italian bread! Cheers!
It isn’t easy getting hold of fire roasted tomatoes here in the UK. Is there something we can substitute? Maybe sun-dried tomatoes or ordinary tinned tomatoes with liquid smoke?
You can just use tinned tomatoes, no big deal. I’d skip the liquid smoke.
This sounds great! Like you with the freezer, I feel like I always buy lentils in bulk (because they are so cheap), and then they get pushed to the back of my cabinet where they sit there for weeks. I’ve been on the lookout for new lentil recipes to avoid this, so hopefully I can whip this one up soon!
I am one of those people that freezes soup – any soups that don’t freeze well? Tips for freezing/thawing?
I had some leftover Chickpea Rice soup but didn’t think that would freeze ok…
No fire-roasted tomatoes where I live (Mexico)… how can I substitute fresh tomatoes and make them taste like something? Thanks!
I’d just chop em up and toss em in! Maybe a dollop of tomato paste, too.
This sounds like a great soup to enjoy now that spring is finally here and things are starting to warm up. Can’t wait to try it!
This sounds so tasty! Yum!
WOW! I need to make this! Thanks, isa.
Great soup…devoured a huge bowl of it last night! Very filling and easy to make. Thanks!!
Hey, foo’, thanks for all the great recipes. If I knew you for real, I’d bake you cookies as a thank you (“merci beaucookie”-style)
Any thoughts about slow-cookering this? Yeah, I ate my lazy biscuits this morning.
Yum! Made this to tonight and will definitely make it again!
Thanks for the great recipe 🙂
You did it again, I am not ashamed to say between the 2 of us we nearly finished the whole thing.
This was outrageously delicious. Absolutely perfect! Thank you!
Made this last night…it was fantastic! The whole family loved it! Thanks 🙂
……..and now i know what i’m having for supper tonight! i only have fresh dinosaur kale and black lentils, though. i am optimistic it’ll still be fabulous! thanks for what i anticipate will be another stellar soup creation, isa!
Yes Yes very good, no spinach so added chard worked out fantastically.
Another keeper! Had this for dinner tonight, it is absolutely delicious and smells yummy, too!
I just had this for three consecutive (non-breakfast) meals. Dynamite! I will make this again – thank you.
i made this last night…my new favorite! tonight for the second time around i added field roast apple sage vegan sausage to it….a perfect flavor addition to the sweet smoky paprika!
[…] Vegan food. New camera. I combined two PPK recipes: Smoky Tomato Soup with Lentils and Olives dished over the Polenta from the Rustic Winter Stew. Both recipes are fantastic and easy. […]
Made this tonight and although it came out a tad on the salty side it still tastes amazing. I’ll cut down the salt next go.
You are genius!
This recipe looks fantastic and I absolutely LOVE the part where I get to crush tomatoes with my hands!
Loved it! Added some kale as well and all of us preferred the added texture.
I made this last night and it is, hands down, my favorite lentil soup now. Thanks, Isa!
Woohoo!
Just made this soup for lunch and ate two bowls. Will probably eat more for dinner… Eating like this has made becoming vegan at 49 easier than I thought it would be! Thanks for another amazing recipe!
I made this tonight for my daughter and myself and it was soooo good!!! I didn’t have smoked paprika, so I used a tablespoon of regular paprika and 2 teaspoons of chipotle powder. it was good and spicy!!! We both agreed it was our new favorite soup!
This is fantastic and will definitely make it again…and again…and again. A keeper!! Just pre-ordered your new cook book on Amazon, can’t wait! Thanks for the great recipes! As someone who is new the being vegan, I am never disappointed in your recipes!
C’est absolument délicieux ! Merci.
Cook this for Maggie
Amazing soup! I made it on Sunday and now I’m sad that it’s all gone. Definitely going to make it into my regular rotation!
I made this last night and cannot stop raving about it. I didn’t have smoked paprika, but it didn’t seem to matter that much.. as I got two big thumbs up from my vegan bf. I also took the advice of previous comments regarding not adding much salt, as the olives lend a lot. Isa, I cannot get over how ALL of your recipes i have made to date are awesome and delish! Thx!
I love the look of this! I’m not sure I can get fire-roasted tomatoes (wilds of North Wales) but a can of peeled ones should work. I’m SO EXCITED to make this /soupvirgin
