Nothing beats a comforting bowl of soup when the weather starts to turn to crap.
Can you tell I’m not a fan of the cold? One thing that makes the darker months more bearable is filling up your house with the smell of a simmering soup.
I absolutely love lentils and one of my favorite things to do with them is make a lentil and vegetable soup. Lentils are full of protein, vitamins and minerals. They’re a super easy way to get protein as a vegan.
❤️ Why you'll love this lentil soup
- Healthy and full of fiber, protein and nutrients since it's packed with vegetables and lentils

🧂 Ingredients
- Lentils - Brown or green lentils work best in this recipe. No need to pre soak them. If you use red lentils, the flavor and texture will change, since red lentils are a bit sweeter and don't take as much time to cook.
- Celery - make sure to chop them up to the same size as the carrots and potatoes, so you can easily get each different vegetable on your spoon at once.
- Potatoes - I like to peel them, because I don't like the texture of the peel, but feel free to keep them unpeeled.
- Onions and garlic
- Italian seasoning - instead of using a bunch of different seasonings, I like to get the Italian seasoning blend to make it easier.
- Vegetable broth or bouillon cubes
- Canned tomatoes - fire roasted tomatoes taste amazing in this recipe.
- Kale
- Carrots - peel then chop them up about the same size as the potatoes, and celery.
- Lemon - top with a squeeze of lemon to bring everything together. The acid from the lemon balances out all of the flavors
👩🍳 Expert tips
Chop up all of the vegetables about the same size. I like to be able to have multiple vegetables plus the lentils in one bite. If you chop anything too large, you might get a big mouthful of just carrot or potato

🥄 Variations
This soup would taste amazing with some curry powder, instead of Italian seasoning. Add a little smoked paprika as well.
Feel free to add in any vegetables that you may have on hand. Pretty much all vegetables go well in this soup.

❓ FAQ's
Yes! This freezes beautifully. I love making a gigantic batch of this soup and freezing it for the days I don’t feel like cooking
Lentils don't need to be soaked before cooking, since they cook faster than other dried beans. You do need to sort through and rinse them before cooking, to wash away any debris and pick out any tiny pebbles or sticks that may be in the bag.
