How to Make This Red Lentil Soup Recipe
Making red lentil soup vegan is a simple process that can be accomplished in just a few steps. Begin by rinsing the red lentils well in a colander. If you have a sensitive stomach, you can soak the lentils first and then rinse them thoroughly.

Next, heat a large saucepan over medium heat and add in the olive oil. Once the oil is heated, add in the chopped onion and carrot, and cook for about 3-4 minutes or until they are softened. Now add in the bay leaves and Italian spice blend, and cook for another 1-2 minutes. Add in the minced garlic and cook for another 30 seconds.
After that, pour in the “chicken-less” broth or vegetable broth, water, red lentils, tomato paste, and hot chili flakes. Bring the soup to a boil, then reduce heat and let it simmer for 15 minutes. Stir the soup occasionally to prevent it from sticking to the bottom of the pan or burning.
When the soup is done simmering, scoop out 2 cups of the soup and transfer it to a blender. Blend the soup until smooth, then add it back into the pot with the remainder of the soup. Mix well.
If you have fresh greens like spinach or kale, add them to the lentil soup pot and let them simmer for about 5 minutes until they soften. If using kale, massage it with a little bit of olive oil first to remove any bitterness.

Finally, serve the red lentil soup in a bowl and add your desired toppings. You can sprinkle some fresh ground black pepper or fresh herbs like parsley on top to enhance the flavor of the soup. Enjoy your delicious and healthy plant based lentil soup!
