This vegan Tomato Lentil Soup is the ultimate soup for the soul. Easy to make with a surprisingly irresistible flavor!

Those of you that have been with me for a while know that I love vegan soups.
LOVE.
For a few reasons…

(1) They are usually easy and quick to make.
(2) Typically the batches are large so you can refrigerate or freeze some for another lunch or dinner.
(3) They are the perfect vehicle for getting in the most nutrient-dense ingredients, like legumes, vegetables, and grains.
Not only do soups make it easy to get a healthy and delicious meal on the table, they are deeply comforting and pleasing to the senses.
There is something very soul-enriching in making and eating soups. The chopping and prep calms my mind, the simmering of the stew fills the house with aromatics, and there is a feeling of ‘plenty’ to see a large pot of soup waiting to be eaten on the stove. Indeed, soups are soul-satisfying.
So much for me that I my soups chapter in LTEV is called Vegan Soup for the Soul.
I made this Tomato Lentil Soup with Cumin and Fresh Dill from LTEV recently, and was SO surprised by our daughter’s reaction when I served it. Went something like this:
Daughter: What soup are we having tonight?
Me: I’m not sure if you remember this one, I haven’t made it for a while – have a taste.
Daughter: Yum, I LOVE this soup, this is the soup you made on New Year’s Eve!
That would be New Year’s Eve TWO years ago! I was shocked she remembered it, particularly because I hadn’t given it a quirky name like “Sniffle Soup” – which they know very well. But, their friends joined us that year on New Year’s and when I asked her how she remembered, she said “oh, I remember this soup because we all brought it downstairs and had it with that yummy bread and everyone loved it“. We remember the food we love and memories are created, apparently even as wee ones.
Another food we love is cashew cheese. For this version, I added fresh herbs and a just a couple of sun-dried tomatoes (one of the suggestions in the Truffled Cashew Cheese – recipe is in Let Them Eat Vegan). It pairs fabulously with this Tomato Lentil Soup.

I share this soup with you today, because maybe it’s a little chilly where you are too… or maybe because you’d like to create a few new soup memories.

Tomato Lentil Soup with Cumin and Dill
Ingredients
- 2 tbsp water
- 1 1/2 cups onion chopped
- 3/4 cup celery chopped
- ½ cup carrots chopped
- 4 large cloves garlic
- 2 ½ cups white potato peeled and chopped (OR 1 1/2 cups cooked brown rice, added later, see note)
- 1 – 1 1/2 cups cauliflower chopped
- ½ tsp cumin seeds
- 1 tsp ground cumin
- 1 tsp dill seeds
- 1 tsp dry mustard
- 1 tsp sea salt
- Freshly ground black pepper
- 2 cups red lentils rinsed
- 2 cups vegetable stock
- 3 ½ – 4 cups water more if using cooked rice, see note
- 1 bay leaf optional
- 1 can 28 oz crushed or diced tomatoes
- 2-3 tbsp fresh dill finely chopped
Instructions
- Heat the water in a large pot over medium or medium- high heat. Add the onion, celery, carrot, garlic, potato (if using), cauliflower, cumin seeds, ground cumin, dill seeds, dry mustard, salt, and pepper. Stir, cover, and cook for 8 to 9 minutes, stirring occasionally. Add the lentils, stock, 3 1⁄2 cups of the water, and the bay leaf. Bring the mixture to a boil, then lower the heat to medium-low, cover, and simmer for 25 to 30 minutes, until the lentils have cooked through and are softened. Then, add the tomatoes (and brown rice, if using instead of potato), and turn off the heat. Remove the bay leaf, and using an immersion blender, puree the soup until completely smooth. Turn on the heat again to medium-high, and cook the soup for another 5 or more minutes to heat through (you can return the bay leaf to the soup or not). Once reheated, stir in the fresh dill, remove the bay leaf, and serve, sprinkling with extra fresh dill, if desired (chives or green onions are also nice addition, as pictured). Serves 6 or more.

Dreena, could you throw everything in the Instant Pot (using potatoes instead of rice)? If so, any suggestions as to time etc?
Devin says
Making this right now! Just curious as to why we add the tomatoes later?

Hello Dreena
I stumbled upon your website through facebook and thought to make this soup. Although I did not have dill or dill seed, decided to give it a try. Oh my, it turned out soooooooooo delicious. I make many different kind of soups (I am a vegetarian), but this is one of the best tasting soups. Thank you so much!! The only thing extra I added was couple spoons of sugar to bring the sourness of tomatoes down. Just loved the taste and texture.

Thanks so much, I appreciate the feedback NJ. 🙂

I cannot say enough about this soup. There is so much flavor in it and it is by far the best soup I have ever tried!! I can’t wait to make it again, I was going to make more the very day I ran out but was out of veggie broth.

That is just wonderful to read, thanks Heather!
