Lentils are the star of this delicious and easy vegetarian soup recipe. They are a great source of protein, fiber, and essential nutrients. You can use any variety of lentils you prefer, such as brown, green, or red lentils. Each variety has its own unique texture and flavor, so feel free to experiment and find your favorite.


A variety of vegetables adds color, flavor, and nutrients to this lentil soup. Some popular choices include carrots, celery, onions, bell peppers, and tomatoes. Feel free to use any vegetables you have on hand or prefer.


Spices are what give this lentil soup its flavorful kick. Some common spices used in lentil soup recipes include cumin, coriander, turmeric, paprika, and bay leaves. You can adjust the spices according to your taste preferences and add more or less depending on how spicy you like your soup.

Broth or Water

To make the soup base, you will need either vegetable broth or water. Vegetable broth adds an extra layer of flavor to the soup, but if you don’t have any on hand, water works just fine too. You can also use a combination of both for a more balanced flavor.


Rinsing the lentils

Before cooking the lentils, it is important to rinse them thoroughly. This helps remove any dirt or debris that may be present. Simply place the lentils in a colander and rinse them under cold running water until the water runs clear.

Chopping the vegetables

Next, you will need to chop your vegetables. Start by peeling and chopping the onions and garlic. Then, wash and chop the rest of the vegetables into bite-sized pieces. The size can vary depending on your preference, but aim for consistency to ensure even cooking.

Sauteing the onions and garlic

To enhance the flavor of the soup, sauté the onions and garlic in a large pan with a drizzle of olive oil. Cook them over medium heat until they become soft and translucent, usually around 5 minutes. This step helps to release the aromatics and adds a depth of flavor to the soup.

Adding the lentils and vegetables to the crockpot

Once the onions and garlic are sautéed, it’s time to add the lentils and vegetables to the crockpot. Make sure to drain any excess water from the lentils and then transfer them to the crockpot along with the chopped vegetables. Stir everything together to combine.

Adding the spices and broth or water

Now it’s time to add the spices and liquid to the crockpot. Sprinkle in your desired spices, such as cumin, coriander, turmeric, and paprika, and give everything a good stir. Then, pour in the vegetable broth or water, making sure it covers the lentils and vegetables by at least an inch.

Cooking on low for 6-8 hours or high for 3-4 hours

Set your crockpot to low and let the soup cook for 6-8 hours, or if you’re short on time, you can cook it on high for 3-4 hours. The longer cooking time allows the flavors to meld together and the lentils to become tender. The result is a hearty and flavorful soup that is perfect for chilly days.

Blending or mashing the soup (optional)

Once the soup has finished cooking, you have the option to blend or mash it for a smoother consistency. If you prefer a chunky soup, you can skip this step. However, if you like a creamier texture, use an immersion blender or a regular blender to puree a portion of the soup until smooth. Be careful when blending hot liquids and ensure the soup has cooled slightly before blending.

Serving and Storage

Serving the soup

After the soup is cooked to perfection, it’s time to serve and enjoy. Ladle the hot soup into bowls and garnish with fresh herbs, such as parsley or cilantro. You can also serve it with a side of crusty bread or a simple green salad for a complete and satisfying meal. The soup is even better the next day as the flavors continue to develop.

Storing leftovers

If you have any leftovers, store them in an airtight container in the refrigerator. The soup will keep well for up to 4-5 days. When reheating, you may need to add a splash of water or vegetable broth to thin it out as the lentils tend to absorb the liquid as they sit. Alternatively, you can freeze the soup in individual portions for up to 3 months for future meals.

Tips and Variations

Adding additional vegetables or legumes

Feel free to get creative and add additional vegetables or legumes to your lentil soup. Some popular choices include spinach, kale, zucchini, sweet potatoes, or chickpeas. Adding extra vegetables not only boosts the nutritional content but also adds more texture and flavor.

Adjusting the spice level

If you prefer a milder soup, you can reduce the amount of spices or omit certain ones altogether. On the other hand, if you enjoy a spicier kick, feel free to increase the spices or add some red pepper flakes for an extra punch.

Using different types of lentils

While the recipe calls for a specific type of lentil, don’t be afraid to switch things up and experiment with different varieties. Each type of lentil has its own unique texture and flavor. For example, red lentils tend to cook faster and have a softer texture, while green or brown lentils hold their shape better and have a slightly nutty flavor. Mix and match different lentils to find the combination you enjoy the most.

Adding toppings or garnishes

To add an extra layer of flavor and texture to your lentil soup, consider adding some toppings or garnishes. Some popular options include a dollop of Greek yogurt, a squeeze of fresh lemon juice, a sprinkle of croutons or toasted nuts, or a drizzle of extra virgin olive oil. These additions can elevate the soup and make it feel even more special.
