Instant Pot Lentil Soup Recipe

Many days I find myself craving comfort food, and this brown lentil soup has become a comfort food favorite in my house. I think we all love it so much because it’s hearty and has tons of flavor. Don’t you get tired of boring soups? I know I do, and that’s why I love this Instant Pot lentil recipe…it’s anything but boring!

What Is Lentil Soup?

Lentil soup is a dish that’s filled with lots of lentils, veggies, and seasonings. Many recipes have meat like ground beef. It’s known for its comforting flavors and seasonings. You can make it vegetarian or even vegan if you replace the chicken broth with vegetable broth too. 

What Are Lentils?

Lentils are relatives of beans, chickpeas, and even peanuts! They are legumes and pack a huge punch of protein. There are several different types of lentils, and they all have a little bit of different flavor. 

  • Red & Yellow – These are some of my favorites because they are slightly sweeter. 
  • Brown – They are earthy flavored and a very popular variety. 
  • Green – Often, people use green lentils as topping for their salads. 
  • Black – You’ll find black legumes paired with dishes that have meat because they go so well together.

What’s In Lentil Soup?

My Instant Pot lentil soup recipe has lots of yummy ingredients just waiting for you to throw together. You won’t find an easier Instant Pot lentils recipe, and the best part is how delicious it is. Take a look at these ingredients:

  • Celery – I almost always add celery to my soup in Instant Pot recipes because it adds a nice flavor and texture. 
  • Carrot – Give yourself some added nutrients by placing some carrots in the best Instant Pot soup ever!
  • Garlic – I used 3 cloves, but you could always add a little more or less, depending on your preference. 
  • Onion – Adding onion gives this Instant Pot lentil recipe even more tasty flavor. 
  • Diced tomatoes – Not only does the tomatoes give the soup some color, it makes it taste even better too. 
  • Lentils – Choose any color of lentils that you like or have on hand. I prefer brown, but anything will do. 
  • Italian seasoning – Yum, you can’t go wrong with adding a little Italian seasoning to this lentil soup. 
  • Thyme – I prefer to always use fresh thyme when cooking. You could use dried if fresh wasn’t an option for some reason. 
  • Chicken broth – If you want to make a vegan lentil soup, use vegetable broth instead. 
  • Baby spinach – Adding spinach adds to the nutrient value of the soup and enhances the color too. 
  • Salt and pepper – Add a little bit to taste. 
  • Freshly chopped parsley – Parsley will add color and is a great garnish. 
  • Shredded parmesan – While the parmesan is optional, I love the added flavor it gives to the easy soup.

Why Am I Getting A Burn Reading From Instant Pot?

While it doesn’t happen a lot, sometimes you will get a burn notice from the Instant Pot. This means that something has stuck to the pot, and the pressure cooker alerts you so you can give it a quick stir. Once you stir it and scrape the bottom of the pot, you can continue cooking without any issues.

The pressure cooker is wonderful at letting you know there is an issue, so your entire meal isn’t ruined. You’ll mostly get the burn notice with foods like rice, creamy soups, or pasta. 

How Long Does Lentil Soup Last In Refrigerator?

You can store the leftover brown lentil soup in the fridge for 3-4 days. Make sure to let it cool down all the way before refrigerating. Never let the soup sit out for longer than 2 hours at a time, or it will go bad. Keep the soup in storage containers with tight-fitting lids, so it lasts the longest possible. 

Can You Freeze Lentil Soup?

Yes, you can easily freeze this brown lentil soup. Pour the soup into freezer bags and remove any air. Lay them flat in the freezer until they have frozen all the way. Once frozen, you can easily move them around in the freezer to make more room. Don’t forget to label the bag, so you know what’s in it. 

Additionally, you can freeze the soup in plastic containers too. I prefer the bags because they take up less space and are easy to thaw out. No matter which method you choose, the soup will last up to 6 months in the freezer. So this is a perfect dish for meal prep!
