Why Does This Recipe Work?

There is a slew of reasons why you should make this Instant Pot vegan Lentil Soup.

  • This isn’t your ordinary lentil soup! It has a texture that is nearly meaty, and it is thick and creamy. The addition of potatoes not only adds texture to the soup but also thickens it naturally.
  • Allergen-free and healthy. It’s hearty, but it’s also healthy, with lentils that are high in protein, fiber, and iron. It’s also soy-free, vegan, gluten-free, and nut-free. Only plant-based ingredients are used, but you can add any toppings you choose.
  • Simple and quick. There are only 10 minutes of hands-on cooking, after which the Instant Pot does its magic. Furthermore, all of the ingredients are easy to find.
  • Friendly to meal prep and freezing. This soup freezes beautifully and is a terrific alternative for meal prep.
  • Suitable for the Instant Pot. In the instant pot, this soup is much easier to prepare and it keeps it warm for hours.

  • Olive Oil: The soup is made richer with the use of olive oil. It is best to use extra virgin olive oil however you can use any.
  • Garlic: Minced garlic gives the soup a great flavor. Fresh garlic should be minced by hand or using a garlic press, and I highly recommend doing so.
  • Green onions: You get a grassy yet savory flavor by adding the green onion. If you don’t have green onions, you can use scallions as well.
  • Onion, carrots, and celery: These three ingredients form a mirepoix, a traditional soup seasoning basis.
  • Fresh ginger: It is anti-inflammatory and good for digestion.
  • Herbs & spices: I used a combination of fresh thyme, cayenne pepper, and allspice. This blend of spices brings a slightly smoky, warm, and earthy flavor to the soup that is just irresistible.
  • White potato, peeled and diced: Potatoes add a starchy texture to the soup. 
  • Sweet potato: Sweet potatoes can be found in almost any grocery shop or farmer’s market. When purchasing sweet potatoes, choose those that are firm to the touch. They aren’t supposed to have wrinkled skin. Also, stay away from those with dark stains or cracks. I used a small one. The sweet potatoes will need to be washed to remove any dirt, peeled, washed again, and cut into equal cubes.
  • Salt: Adding salt to the soup helps to bring the flavors together and make the dish complete.
  • Lentils: Lentil soup can be made with either dried brown or green lentils. This recipe does not work with lentils that are red or orange because they cook too quickly.
  • Vegan bouillon cube: Bouillon cubes contain significantly more sodium, which enhances the flavor due to the addition of traces of MSG. If you don’t have bouillon cubes, you may use either one cup of fresh stock OR one cup of canned broth in place of each cube. Here is my homemade Vegetable Broth Recipe.
  • Coconut milk: I used coconut milk for the creamy and smooth texture but any type of plant-based milk will work.

Then finally add water, vegetable bouillon, allspice, salt, and cayenne.

Instant Pot Vegan Lentil Soup Recipe Notes

  • I decided to make a Jamaican-style Lentil Soup, so I used thyme, ginger, allspice, and a little coconut milk.
  • I added just enough coconut milk so as not to have a strong coconut taste, you can add more if you love the flavor.
  • The flavor was hearty and out of this world. I added some dumplings after I took the photos but didn’t include them in the recipe. In Jamaica, we love dumplings in our soup so I added some for my hubby.
  • You can check out my Gluten-Free recipe or my new favorite recipe that tastes and have the exact texture of regular white flour Jamaican dumplings is to use Pillsbury gluten-free flour.
  • Just add a little salt and water to form a dough, roll it into dumplings, and cook in the soup, might have to add extra water.
  • I used water plus 1 vegetable bouillon but you could use all vegetable broth instead and just adjust salt to taste after the soup is done.
  • If you want you can saute onion, garlic, green onion, and ginger.

Reheating And Storage

  • Make-Ahead: This instant pot lentil soup dish is great for meal planning. It can be prepared up to 7 days ahead of time and will taste excellent for the entire week!
  • Storage: Refrigerate leftover lentil soup for up to a week in an airtight container.
  • Freezing: This soup can be frozen for up to 3 months if kept in an airtight container. Thaw overnight in the refrigerator before eating.
  • Reheating: Reheat this vegan lentil soup in a pan on the stovetop. Add more broth or dairy-free milk to loosen it, and then reheat over medium-low heat until thoroughly heated. It can be reheated in the microwave. Before serving, taste and season with salt if needed.

Recipe Variations & Suggestions

Feel free to adapt this recipe to your family’s preferences by substituting different ingredients. Here are a few of our personal favorites:

  • For extra flavor: A pinch of cumin powder, curry powder, turmeric powder, or chili powder.
  • Red Lentil: I suggest using brown lentils for this soup because they keep their shape better when cooked. If you have red lentils only, you can still make the soup, but the texture will be different due to the lentils’ disintegration while cooking.
  • French Lentil Soup: To make a more traditional French lentil soup, leave off the cumin and smoky paprika and use French green lentils instead. To give the soup more flavor, start by sautéing some chopped bacon before adding the onion, carrot, and celery.
  • Beans: If you want to add beans, use canned white beans and stir them in when the soup has been pressure cooked.
  • Other Greens: For garnish, you can use fresh spinach, kale, or chard. After the soup has finished cooking, add chopped fresh greens.
  • Topping: Add Parmesan (or vegan cheese), fresh chopped parsley, and a dash of spicy sauce.
  • Thickness: If you want a thicker or thinner soup, adjust the amount of liquid you add.
  • Herbs: The use of fresh herbs makes a significant difference. While you may certainly use a blend of dry herbs, fresh herbs provide a more vibrant and fresh flavor.

What Is The Ratio Of Water To Lentils In An Instant Pot?

Uncooked lentils are added to this soup, therefore it is crucial to ensure there is enough liquid to cook them correctly. One part lentils to three parts water are the best ratio for cooking lentils. However, because we’re also cooking a lot of vegetables in this soup, we add a lot more liquid before we start cooking.

Do You Need To Soak Lentils Before Pressure Cooking?

This is not the case in this recipe! Other recipes might enquire about this, but this lentil soup recipe for the instant pot doesn’t need to be soaked the lentils first, which makes it easy to make.

How Do You Make Soup With An Instant Pot?

Weeknight dinners are a breeze to prepare with the instant pot!

Some vegetables or other ingredients are normally sautéed in the pot first. Then we add the other ingredients and liquids to the pot and cook the soup at high pressure for 15 minutes or until it’s done is standard procedure when using an instant pot.   

What Goes With Lentil Soup?

Lentil soup is a complete meal in itself. However, there are a few items that go well with it to complete the meal. Namely…

  • A dinner roll
  • A slice of crusty bread
  • Crackers
  • A side salad
  • Mashed potatoes
  • White or brown rice

Can I Add More Vegetables To This Soup?

Yes. Adding some baby kale or baby spinach to the soup might be a fantastic addition. Cook for a few minutes on the Sauté setting, until the greens have wilted.

Can I Use Other Lentils Than Brown Lentils?

Of course! However, be prepared to adjust the cooking time and recognize that the end result may not be the same as you see in this recipe.  The time would be cut in half if you used French green lentils. Split red lentils will take around 8 minutes to cook, but they will dissolve just like red lentils.

Why Are My Lentils Still Hard After Cooking?

In an ideal world, we’d use fresh lentils and they’d be done when the time specified on the package. However, there are a few reasons why your lentils could not be fully cooked.

  1. Your lentils may be expired. After cooking, older lentils and beans, such as those that are 1-2 years old, can still feel hard and crunchy, so make sure your lentils and bean haven’t been lying in the pantry for a long time.
  2. It’s also possible that you haven’t sorted your lentils thoroughly enough. Small particles of detritus, such as dirt and pebbles, are frequently found in the lentils. If they are not fully cleaned or sorted, you may wind up cooking with them and experience an unpleasant crunch.

Is Lentil Soup A Good Way To Lose Weight?

If you’re trying to lose weight, you should eat more proteins; therefore, I’ve prepared a protein-rich vegan lentil soup to assist you. Lentils are high in protein and other nutrients, so they’re a must-have in any weight-loss plan.

Is Lentil Soup Healthy?


There are numerous health benefits of lentils, including a reduction in cholesterol, stabilization of blood sugar, weight loss, and a high amount of protein and fiber.

Because extra virgin olive oil contains monounsaturated fats it can help lower the risk of heart problems. Polyphenols, which are antioxidants, are also present.

This simple, nutritious soup with delicate tastes is extremely satiating and filling. The best part is that you can change it up and jazz it up to your heart’s content, and it will still taste fantastic.
