Why This Recipe Works

  1. Basic Pantry Ingredients. If you have lentils in your pantry, a can of diced tomatoes, mirepoix vegetables (onion, carrot, and celery), a few seasonings, and vegetable stock, then you’re good to go! Spinach adds a nice touch if you happen to have it.
  2. Filling. I love soups that are so satisfying and can be served as a main meal. Trust me, this soup will keep you full for a few good hours.
  3. Dump and Start Recipe. So you have the option to sauté the mirepoix vegetables, but do you really have to? The answer is no! If you’re in a hurry, just dump everything in the Instant Pot and come back to a bowl of hearty warm soup.

Ingredients Needed

To make this Instant Pot Lentil Soup, here’s what you’ll need:

  • Lentils – The lentils that I used are brown lentils. Feel free to use French green lentils (also called “Puy lentils”) or red lentils. However, if you use red lentils, consider cutting the cooking time for a few minutes as they cook faster and you will end up with creamier texture. I love lentils because they are packed with protein, iron, potassium, magnesium and B vitamins.
  • Vegetables – Adding carrots, celery and onion makes the base for any soup (known as mirepoix). This is what makes any soup so flavorful!
  • Tomatoes – I used a can of diced tomatoes for the convenience (I always have a few cans in my pantry!) but feel free to use fresh diced tomatoes if that’s what you have available. The tomatoes add to the liquid needed for this recipe.
  • Vegetable stock – I used vegetable broth/stock for a plant based version of this soup, but feel free to replace it with with chicken broth/stock if that’s your preference.
  • Spinach (optional) – I stirred in some spinach leaves at the end of the cooking process to add more nutrients and richness to the soup. You can also change this up, and use kale instead.
  • Herbs and spices – what makes this soup so delicious! I used dried oregano, ground cumin, salt and pepper to taste.

  1. Add All The Ingredients To The Pot – excluding spinach. And give them a stir.
  2. Pressure Cook. Secure the lid and set the vent to SEALING. Select the PRESSURE COOK/MANUAL setting and set the cooking time for 15 minutes at high pressure. The Instant Pot will take around 7-8 minutes until it comes to pressure and starts cooking.
  3. Natural Release. When the cooking time ends, allow for natural release of the steam for 2-3 minutes before quickly releasing the remaining of the steam.
  4. Carefully Remove the Lid. Stir in the spinach leaves and close the lid again and let the soup sit for a few minutes to allow the spinach leaves to wilt. Then adjust the seasonings and the texture to your preference.
  5. Serve. Ladle into soup bowls. Serve with a squeeze of fresh lemon juice. Enjoy!

    Just curious how the salt content (Sodium: 1516mg) could be so high per serving as I don’t see salt as an ingredient?

    This lentil soup is seriously so flavorful and delicious! I used chicken broth instead of vegetable broth, and diced tomatoes with jalapeños instead of regular. Also tossed in a half bag of frozen white corn at the end. Super yummy!

FAQs

Do I need to rinse lentils before making soup? ›

The other good news: Lentils don't need to soak as beans do (though you do need to sort and rinse them before cooking). Different types of lentils cook in different amounts of time. Red lentils are the fastest cooking and they dissolve as they cook and make for a smooth soup.

Why is my lentil soup not thick? ›

Cook It Longer

Sometimes soup just needs to simmer longer to reach the perfect consistency. Check to see if the vegetables are tender, and then taste the broth. If the soup tastes a bit watery, give it more time.

Can you overcook lentil soup? ›

Yes, you can overcook lentils; they will become mushy. Much depends on the type of lentil you're using. Some cook quicker and hold their shape better than others. To avoid overcooking them, always follow the cooking directions in your recipe and use the type of lentils called for in the ingredient list.

What if I put too much water in my lentil soup? ›

You can add some cornflour mixed in little water and let it boil with your soup till get nice thick consistency. And if you are a health conscious fellow then go for cooked oats. As I do, cook some oats along with lentils and then puree it to make soup. This will not only thicken your soup but add some more health too.

What happens if you forget to rinse lentils? ›

It'll be fine. The reason you rinse lentils is to remove any small rocks, husks, and rodent droppings that might have gotten in there.

What happens if you don't pre soak lentils? ›

Soaking: Unlike beans, lentils are small and cook relatively quick (in general, about 20-30 minutes) so they don't require pre-soaking. However, soaking lentils for a few hours or overnight may improve the digestibility of starches in lentils and an overnight soak can also reduce cooking time by about half.

Why is my lentil soup tasteless? ›

Lentils are bland, that's why they are perfect for adding flavour to. Personally, my favourite is to fry up bits of bacon and stir those into the cooked lentils, dead easy and quick. What do I do to keep lentils from being bland and terrible? Add loads of garlic, cumin, onion, and ginger.

Why did my lentil soup turn black? ›

the color change you've observed is from oxidation. If you want to prevent this, lay some plastic wrap over the surface of your lentils to prevent air from getting to them, or add some acid, like lime juice, to the recipe.

Why won't my lentils soften in soup? ›

Editor: First, I wonder how old your lentils are. If they're more than a year or two old, they will often stay crunchy in the middle no matter how long you cook them! Another trick is to wait to add salt or acidic ingredients until near the end of cooking. Take a look at our post on cooking lentils for some more help!

What makes lentils taste better? ›

Think more like you're cooking pasta- you just need significantly more water than lentils. You can also use broth instead of adding an extra layer of flavor. I like adding a bay leaf, an onion cut in half, and a clove of garlic to add flavor to the lentils.

Which color lentils are best for soup? ›

With their hues ranging from yellow to orange to red, red lentils make the perfect velvety base for soups, curries, and dals. These lentils may lose their shape during cooking, but they offer a delicate texture and slightly sweet flavor.

Is too much lentil soup bad for you? ›

Eating half a cup of cooked lentils gives you lots of essential nutrients and their high fiber content makes you feel full. However, the fiber in lentils can be hard for your body to break down. Eating too many lentils can cause gas, bloating, and cramping.

What thickens lentil soup? ›

You can also use flour or cornflour to thicken a soup. Put a tablespoon of either into a small bowl and stir in 2-3 tbsp of the soup until you have a smooth mixture. Stir this back into the soup and bring it to a simmer.

How do you reduce gas in lentil soup? ›

Cumin seeds or ground cumin helps with digestion and is perfect in a soup, curry or dal (lentil dish). Carom seeds, fennel seeds, turmeric and peppermint are other great digestive aids. Cooking beans with a large strip of dried kombu, a Japanese dried kelp, may minimise their gas-producing properties too.

How to tell when lentils are done? ›

Honestly, the best way to tell if lentils are done are to taste them. They should be tender to the bite, with some varieties of lentils being a bit more firm and others more soft. That said, if you would like your lentils to be softer, just simmer them a few minutes longer until they reaches your desired consistency.

Is it OK not to rinse red lentils? ›

Lentils do not require it but can be soaked in order to reduce cooking time by about half. Before cooking, rinse lentils in cold water, pick over to remove debris or shrivelled lentils, then drain.

How long to rinse lentils before cooking? ›

Swish the water, drain, and repeat until the water runs clear. This usually takes six or seven rinses for red lentils, split peas and moong dhal, and as little as two for green or brown lentils.

How important is it to rinse red lentils? ›

It's best to be safe and rinse and sift through them before cooking, because no one wants to break a tooth by biting down on a rock. Follow this tip: Give the lentils a good rinse in a colander to remove any debris and sift through them to be sure there are no hidden stones tucked among the legumes.
