Soup makes a wonderfully filling meal either on its own or with a loaf of bread and a salad. If you enjoy making homemade soup, you might want to try a few more of my recipes.

Instant Pot Zuppa Toscana (Olive Garden copycat recipe) is a favorite pressure cooker soup recipe.

Or, you might want to try my Baked Potato Soup recipe. It comes fully loaded with cheese, bacon, and sour cream! This dinner is utterly life-changing.

If you are looking for a freezer soup, my Homemade Chicken Noodle Soup is a wonderful way to use up what’s left in the freezer.

Made in just 25 minutes, this easy recipe is bursting with fabulous flavor, tender chunks of chicken and veggies.

Making Instant Pot Lentil Soup

This vegan lentil soup can be on the table in less than thirty minutes. It’s a perfectly healthy dinner for your busiest days.

While I’ve used fresh vegetables when making this soup, you can easily use frozen, canned, or leftover.

Just add them toward the end of the cooking time so they don’t get too soft.

Protein options 

Lentils are high in protein on their own. So, there is no need to add any other type of protein to this soup.

But, I know that there are some people who don’t consider it to be dinner unless there is meat in the soup.

You can easily add beef, pork, or chicken to your soup if you want to. Or, if you want to keep this as a freezer meal, you can add whatever leftover meat you have stored in the freezer.

Just add the cooked meat at the same time you add the other ingredients and it will cook perfectly.

If you want to keep this as vegan lentil soup, look for frozen protein crumbles at the grocery store. There are several different vegan options that would work well in this soup.

What type of lentils to use

This recipe is made with brown lentils, but you can use red, black, or green lentils for this as well. Black lentils are one of the healthiest types of lentils. 

They contain 26 grams of protein and 18 grams of fiber. That makes this Instant Pot Lentil Soup one of the healthiest soups I’ve tried.

What to serve with vegan lentil soup

Lentil soup tastes great when topped with parmesan cheese alongside a garlic bread or naan. 

Because it’s a dense, yet healthy soup, you may want to consider a lighter side such as a side salad or fresh vegetables.

How to make the soup vegan 

This Instant Pot Lentil Soup is already vegan provided you use vegetable broth instead of a chicken broth. If you follow my recipe exactly, you won’t need to make any other substitutions.

How to store freezer soup

You can store lentil soup for 3-4 days in the refrigerator. Make sure to store the soup in an airtight container. 

This soup also freezes well after it’s been cooked. You can freeze it for up to 6 months for best quality.

To reheat it, let it thaw in the refrigerator overnight. Then, place it in a pot on the stove and heat it over low heat until it’s warm.

    I made your instant pot lentil soup for a vegetarian friend who has Covid.. I used hatch chilies instead of green bell pepper. It is phenomenally delicious! I know my friend is going to love it. Thank you for sharing the recipe.

    1. Pat, that is such a sweet thing to do for your friend! I love your substitute of Hatch chiles (YUM!) Thank you for your comment and for rating the recipe.
