Very Best Lentil Soup
Lentil soup is a classic vegetarian soup recipe. It’s hearty, healthy, delightfully filling (with plant-based protein), and warming on those cold, wintery days. While there are many variations of lentil soup, you can’t go wrong with a simple, delicious Mediterranean version.
When it comes to lentil soup recipe, let’s remember that simple does not equal boring. Oh no, this recipe is anything but that!
It’s packed with rich flavor, it’s hearty enough to be eaten as dinner, and it’s easy enough to whip up with a few pantry staples and fresh vegetables. That’s why it’s the very best.
When I previously showed you how to cook lentils (so they’re not mushy), I also highlighted why lentils are a powerhouse ingredient in vegan and vegetarian meals. They’re high in fiber, carbohydrates, and most importantly, protein. That means this lentil soup is not just an appetizer soup, but it’s a satiating full meal. And an economical one to boot.
Lentil soup is hearty (yet light), comforting, satisfying and should definitely be in your regular dinner rotation. Bonus, you can meal prep and freeze it as well!
What’s In This Vegan Lentil Soup
A cup of green lentils goes a long way in this cozy, chunky soup. But it’s really the rest of the ingredients that makes your taste buds dance.
- Mirepoix Vegetables: Chopped celery, carrots, onions and garlic are the classics that make us feel closest to home.
- Roasted Tomatoes: A can of fire roasted tomatoes adds a hint of smokiness and lends to this soup’s gorgeous red tone.
- Tomato Paste: All you need are two tablespoons to intensify the body of the soup.
- Kale: An easy way to amp up the antioxidants, vitamins, nutrients, and colors in this soup.
- Lentils: Green or brown lentils work best in this soup.
- Earthy Herbs: A blend of cumin, oregano, basil, and thyme embodies that Mediterranean flavor.
- Liquids: You can use water or broth or a mix of both, which is what I usually do.
- Lemon: Helps to brighten and balance out the deep flavors.

Which Lentils to Use
Green or brown lentils are the best choice for this soup. They have a mild, earthy flavor that slightly breaks apart when cooked, but still maintain their shape. Red lentils break down the fastest and become mushy. And French lentils (also called Lentils de Puy) are great for being tossed in a side dish or lentil salad as they have the firmest texture, but they require more time to cook in a soup.
How To Make The Best Lentil Soup Recipe
- Sauté the vegetables. In a large soup pot, heat the oil and sauté the onion, celery, and carrots for about 5 minutes.
- Add the spices. Stir in the tomato paste, garlic, dried spices, salt and pepper. Cook for 2 minutes until fragrant.
- Add the lentils, diced tomatoes, and broth. Bring it all to a boil, reduce the heat to low, and let the soup simmer for 25 minutes. Keep the pot partially covered with the lid.
- Blend it. For a creamier texture, use a Vitamix immersion blender (it’s so powerful!) to spot blend for a few seconds.
- Add the rest. Stir in the kale, lemon juice, and let it all simmer for 1-2 more minutes. Then taste test to see if you need to add anything else.
Whether you’re serving this soup to guests or enjoying as a meal for two, it’s always fun to perk it up a bit.
- Fresh Herbs: Sprinkle on freshly chopped parsley or cilantro.
- Crispy Bits: Quickly whip up crispy shallots for added crunch or crumbled bacon bits if you’re not vegan.
- A Touch Of Creaminess: Drizzle a little coconut cream or sprinkle freshly grated parmesan on top.
Storing And Reheating Leftovers
- To Store: This will keep in the fridge for up to 5 days in a sealed storage container.
- To Freeze: Keep this in a freezer safe container or pour into a silicone freezing tray for pre-made servings. It will last for several months in the freezer.
- For Reheating: If you’re reheating a single serving, just add it to a bowl and pop it in the microwave for a few minutes until warmed through. But if you’re heating up an entire batch, add it back into a pot and warm it up on the stovetop.

Very Best Lentil Soup
- 1/4 cup olive oil
- 1 onion, small diced
- 2 carrots, small diced
- 2 celery stalks, small diced
- 2 tablespoons tomato paste
- 3-4 cloves of garlic, minced
- 2 teaspoons cumin
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1 teaspoon dried thyme
- salt and pepper, to taste
- 28 ounces fire roasted diced tomatoes
- 6 cups vegetable broth or water
- 1 cup green or brown lentils
- 3 leaves kale, stemmed and sliced
- 1 lemon, juiced
- Heat the oil in a large pot until it shimmers. Add the onion, celery, and carrot and stir for 5 minutes, or until the onion becomes translucent.
- Add the tomato paste, minced garlic, dried spices, salt and pepper. Stir and toast the spices for 2 minutes.
- Add the diced tomatoes, broth, and lentils and stir together. Bring that to a boil, then reduce the heat to low, partially cover with a lid, and simmer for 25-30 minutes.
- You can keep the soup chunky, or use an immersion blender to create a more creamy texture, by spot blending for just a few seconds.
- Stir in the kale and lemon juice, and simmer for an additional minute or two to soften the kale. Taste the soup, and add any additional lemon juice, salt, or pepper before serving.
- Because vegetable broth usually comes in 32 ounce containers (4 cups), I add 4 cups of broth and 2 cups of water to this recipe. Just so I don't have a half used container of broth.
- You can substitute 3 teaspoons of Italian seasoning for the oregano, basil, and thyme.
- As the soup sits, the lentils may soak up some of the liquid, thickening up the soup. You can always add more broth or water to thin it out. Or blend it creamier with my favorite Vitamix immersion blender.
