Lentils are the star ingredient of this delicious instant pot lentil soup. They are protein-packed legumes that are a great addition to any diet. They come in various colors such as brown, green, red, and black, each with its own unique flavor and texture. Lentils are a good source of fiber, iron, and folate, making them a nutritious choice for a healthy soup.


This lentil soup recipe is loaded with a variety of vegetables that not only add flavor but also enhance the nutritional value of the dish. Carrots, celery, onions, and garlic are a classic combination that provides a hearty base for the soup. You can also add other vegetables like bell peppers, zucchini, or spinach to boost the veggie content even more.

Herbs and Spices

To elevate the flavors of the lentil soup, a combination of herbs and spices is used. Common choices include bay leaves, thyme, oregano, and cumin. These aromatic seasonings add depth and complexity to the dish, creating a satisfying and fragrant soup.


The liquid component of this recipe is crucial in creating the desired soup consistency. Vegetable or chicken broth serves as the base, providing depth of flavor. You can also use water, but keep in mind that using broth adds extra richness to the soup. The amount of liquid can be adjusted according to your preference, whether you prefer a thicker or thinner soup.


Topping off your lentil soup with a garnish not only adds visual appeal but also enhances the overall taste and texture. Fresh herbs like parsley or cilantro can add a pop of freshness, while a drizzle of olive oil or a squeeze of lemon juice can brighten the flavors. Other options for garnishing include croutons, grated cheese, or a dollop of yogurt.

Nutrition Information


The calorie content of this instant pot lentil soup can vary depending on the ingredients used and the portion size. A typical serving of lentil soup contains around 200-300 calories. The majority of the calories come from the lentils themselves, which are a good source of plant-based protein and carbohydrates.


Lentils are known for their high protein content, and this soup is no exception. A serving of lentil soup can provide around 10-15 grams of protein, depending on the serving size and the specific type of lentils used. This makes it a suitable option for those following a vegetarian or vegan diet, as it helps meet their protein needs.


One of the key benefits of lentils is their high fiber content. A serving of lentil soup can provide approximately 8-12 grams of dietary fiber. Fiber is essential for maintaining a healthy digestive system and can help prevent constipation. It also promotes feelings of fullness, making this soup a satisfying meal option.


Lentil soup is naturally low in fat, especially if prepared with minimal added fats or oils. The fat content mainly comes from any added oils or garnishes used. Using minimal or healthy oil options like olive oil can help keep the fat content in check.

Rinsing the Lentils

Before cooking the lentils, it is important to rinse them thoroughly. This removes any dirt or debris and helps eliminate any bitterness. Place the lentils in a colander and rinse them under cold running water while gently rubbing them between your hands. Continue rinsing until the water runs clear.

Chopping the Vegetables

Prepare the vegetables by peeling and chopping them into small, uniform pieces. The carrots should be diced, the celery sliced, and the onions finely chopped. Garlic can be minced or sliced depending on personal preference. This step ensures that the vegetables cook evenly and adds texture to the soup.

Sautéing the Vegetables

Using the sauté function on your instant pot, heat a small amount of oil or cooking spray. Add the chopped onions and garlic and cook until they become translucent and fragrant. Then, add the diced carrots and sliced celery and continue sautéing for a few more minutes. Sautéing the vegetables helps bring out their flavors and adds depth to the soup.

Adding the Lentils and Liquid

Once the vegetables are sautéed, add the rinsed lentils to the instant pot. Mix well to coat the lentils with the flavors from the sautéed vegetables. Then, pour in the desired amount of liquid, whether it’s broth or water. The liquid should cover the lentils and vegetables, but not exceed the maximum fill line of the instant pot.

Cooking Under Pressure

Secure the lid of the instant pot and set it to pressure cook for the recommended time. The cooking time may vary depending on the type and size of lentils used. Generally, green or brown lentils take about 15-20 minutes, while red lentils cook faster, around 8-10 minutes. Once the cooking time is complete, allow the pressure to release naturally or use the quick-release method.

Customizations and Variations

Addition of Meat or Protein

If you prefer a heartier soup, you can add meat or protein to the lentil soup. Diced chicken, ground turkey, or cooked sausage can be added at the sautéing stage along with the vegetables. This adds extra flavor and protein to the soup, making it a more substantial meal option.

Adding Grains or Pasta

To create a more filling and substantial soup, you can add grains or pasta. Barley, quinoa, or rice can be cooked along with the lentils and vegetables, absorbing the flavors of the soup. You can also add small pasta shapes like macaroni or shells for a comforting twist.

Creamy Lentil Soup Variation

For a creamy texture, you can blend a portion of the cooked lentil soup using an immersion blender or a regular blender. This creates a smooth and velvety consistency, perfect for those who prefer a thicker soup.

Spicy Lentil Soup Variation

If you enjoy a bit of heat, you can add spices like chili powder, cayenne pepper, or red pepper flakes to the soup. Adjust the amount according to your spice tolerance. Additionally, adding diced jalapeños or hot sauce can add an extra kick to the soup.

To enhance the presentation and flavors of the lentil soup, various garnishing options can be used. Fresh herbs like parsley or cilantro can be chopped and sprinkled on top. A drizzle of olive oil or a squeeze of lemon juice can add a citrusy note. For added texture, you can sprinkle croutons or grated cheese on top.


Lentil soup is versatile and can be enjoyed on its own or paired with other dishes. Serve it with a side of crusty bread or a grilled cheese sandwich for a comforting meal. A side salad or steamed vegetables can add a refreshing balance to the soup.

Tips and Tricks

Using Different Types of Lentils

Experiment with different types of lentils to discover your preferred flavor and texture. Brown and green lentils hold their shape well and have a slightly nutty taste. Red lentils break down easily and result in a smoother consistency. Black lentils have a firmer texture and earthy flavor. Each type offers a unique twist to your lentil soup.

Adjusting the Soup Consistency

If you prefer a thicker soup, you can mash a portion of the cooked lentils with a fork or a potato masher. This creates a more substantial texture. Conversely, if the soup is too thick, you can add more liquid, such as broth or water, to achieve the desired consistency.

Make-Ahead and Freezing Tips

Lentil soup can be made ahead of time and stored in the refrigerator for up to 3-4 days. Reheat it on the stove or in the microwave before serving. If you want to freeze the soup for longer storage, allow it to cool completely and transfer it to airtight containers or freezer bags. Frozen lentil soup can be kept for up to 3 months. Thaw in the refrigerator overnight before reheating.

Can I use canned lentils instead of dried lentils?

While the recipe calls for dried lentils, you can certainly use canned lentils as a time-saving option. However, note that canned lentils are already cooked, so they may break down more easily and result in a softer texture. Adjust the cooking time accordingly and consider rinsing the canned lentils before adding them to the soup.

What can I do if the soup is too thick?

If the lentil soup turns out thicker than desired, you can add more liquid, such as broth or water, to thin it out. Gradually add small amounts until you reach your desired consistency. Allow the soup to simmer for a few minutes to incorporate the added liquid.

How can I make this soup gluten-free?

This lentil soup recipe is naturally gluten-free, as it does not contain any wheat-based products like pasta or flour. However, it’s important to check the labels of any pre-made ingredients, such as broth or spices, to ensure they are certified gluten-free.
