The benefits of lentils
Lentils are a great source of protein and they are packed with fiber and vitamin B. They're also very good for heart health. Vegans use lentils as a regular source of protein. They are considered legumes and cook much faster than beans.
In addition to all these facts, it's good to know that lentils are also a good source of iron, since each cup of lentils has about 6 milligrams of iron. You can read more about lentils and how to use them on Well and Good.
Ingredients and substitutions
- Onions and garlic: You can use yellow or white onion and use fewer garlic cloves if you're not a fan of garlic. It's best not to use garlic powder.
- Leek: Adds a lot of flavor to the soup and is a healthy addition to any meal. Make sure to wash it thoroughly since it has many layers.
- Green lentils: You can also use brown lentils for this recipe.
- Spices: You need oregano, paprika, turmeric, cayenne and salt for this recipe.
- Tomato paste: Not tomato sauce or crushed tomato. Tomato paste has a concentrated flavor and color so make sure not to overuse it.
- Chicken stock: Either homemade or store-bought would work. To make this soup vegetarian, use vegetable stock.
Instructions
- Press the sauté function on the instant pot and heat some olive oil in the pot. Sauté the onion and garlic for a couple of minutes until golden. Add in carrots and cook for a few minutes. Add the leek and cook until they're almost soft.
- Now add the lentils, spices and tomato sauce. Stir well and pour in the chicken stock and water. Give it a nice stir and lock the lid. Make sure the valve is on sealing. Press cancel and then press pressure cook (or manual) set the timer to 15 minutes on high pressure.
- Once the instant pot beeps indicating that the cooking is done, let it release the pressure naturally for 5 minutes and then do the quick release by turning the valve to venting. Once the pressure is all released and the lid is unlocked, lift the lid, stir the veggie lentil soup and serve in bowls with some lemon.
- Do a natural release for 5 to 10 minutes and then a quick release.
Variations
This lentil soup recipe is so versatile and you can modify it to your liking:
- Add other vegetables such as potatoes or turnips.
- You can use leafy greens such as spinach or kale.
- Make it spicy by adding ½ to 1 teaspoon cayenne pepper.
Frequently asked questions
You don't need to soak lentils in water before cooking them. While soaking beans such as black beans, red beans or chickpeas speeds up the process of cooking, there is no need to do it for lentils because lentils cook pretty quickly. Cooking lentils in instant pot takes about 15 minutes, quick and easy!
Yes, you can use red lentils instead of green lentils in this recipe. But be aware of the fact that when red lentils cook, they lose their shape and make a thick soup and the color will be light brown.
Lentil soup freezes beautifully therefore you can make a big batch and freeze half of it for a later date. Let the vegetable lentil soup cool completely and then divide it into different airtight containers. Freeze for up to 3 months.
To reheat, take the frozen veggie lentil soup out of the container and place it in a pot. pour ½ cup water in the pot and turn the heat on. Let the soup cook on low and stir occasionally to break it. Cook for about 20-30 minutes until completely heated through.
Serving suggestions
This instant pot soup is the perfect meal on its own and would be perfect with a light side dish such as Mediterranean salad or cucumber tomato avocado salad. You can also simply serve this soup with some crusty bread such as sourdough.
Notes and tips
- To make vegetarian lentil soup, leave out the chicken stock and use water or vegetable stock instead.
- You can add other vegetables to this soup such as celery, spinach or bell peppers. If using spinach, add it after the soup is ready. Open the lid, add the spinach, give it a quick stir and serve.
- Store the leftovers in an airtight container and refrigerate for up to 3 days. You can reheat the soup in the microwave or in a sauce pan.
- The amount of time needed to make this lentil soup is almost the same as making it on stove top. However, instant pot lentil soup doesn't require any stirring and is pretty much hands-off.
