Vegan Instant Pot Lentil Soup features potatoes and spinach. You can walk away while it cooks and let your pressure cooker do the work. Plus lentils don't require soaking, so the prep time is minimal.
I love making soup in my Instant Pot. Not only is an electric pressure cooker easy to use, it's great for busy people.
You can make recipes like Vegan Potato Leek Soup, Vegan Potato Corn Chowder, and Vegan Wild Rice Soup without constantly stirring or watching to make sure the pot doesn't boil over.
And for soups using dried beans or legumes, like this Instant Pot Lentil Soup, they cook in less time than they would on the stove. And this version is loaded with comforting flavors and textures.
Why you'll love this recipe
- It's thick and chunky with delicious flavors.
- You can walk away and do something else while the soup cooks.
- It's perfect for meal prep and is freezer friendly.
Instant Pot Lentil Soup is made with readily available ingredients you may already have on hand in your kitchen. Here's what you'll need:
- Olive oil (or use water for an oil-free version)
- Bay leaf
- Dried thyme
- Potatoes (I recommend yellow or gold, but white or red can also be used)
- Brown or green dried lentils (If you are looking for a recipe that uses red lentils, try my Red Lentil Potato Soup or Instant Pot Vegan Chili.)
- Vegetable broth (or water)
- Fresh spinach (or use your favorite dark leafy greens such as Swiss chard or kale)
- Salt and pepper
For the complete list of ingredients with measurements plus recipe instructions, please see the recipe card at the bottom of this post.
You can use a 6-quart Instant Pot or an 8-quart model for this recipe.
Instant Pot Ultra 80 Ultra 8 Qt 10-in-1
- Programmable Pressure Cooker, Slow Cooker, Rice Cooker, Yogurt Maker, Cake Maker, Egg Cooker, Sauté, and more
- Altitude adjustment, cooking indicator, and a steam release reset button
- Developed with the latest 3rd generation technology with an embedded microprocessor
- Use the saute function to cook the onion, garlic, carrots and celery until lightly softened.
- Next add the bay leaf, thyme, potatoes, lentils, and vegetable broth or water. Give everything a quick stir.
- Then close the lid and set the timer for 7 minutes. Keep in mind that it will take time for the Instant Pot to come up to pressure before the 7 minutes start. After the 7 minutes is up, it will take some time for the pressure to release naturally.
- After it does, remove the lid, and stir in the spinach. Add some salt and pepper, to taste, and serve.
Stove top instructions
If you don't have an electric pressure cooker, you can make this recipe on the stove in a Dutch oven or large pot. Add an extra cup of liquid and simmer for 30 to 40 minutes until the lentils and potatoes are soft. Then stir in the spinach.
This lentil soup with potatoes and spinach is a complete meal on its own. Or you can serve it with salads or sides such as the following:
Storing and freezing
Leftover lentil soup can be covered and refrigerated for 3 to 4 days. You can reheat it on the stove or in a microwave.
Or you can freeze individual portions in mason jars or storage containers. Fill the glass jar with cooled soup, allowing some room at the top for expansion. Don't forget to label your lid so you and everyone else in your house knows what's inside.
Then before you want to eat one of the portions, transfer it to the refrigerator to defrost. Since soup tends to thicken when stored, you may want to add it to a sauce pan with a little water before reheating it.
Red lentils are softer and will disintegrate when cooked, while brown or green lentils will hold their shape. For this Instant Pot Lentil Soup recipe, you should not use red lentils.
It generally takes between 5 to 15 minutes for an Instant Pot to get to high pressure.
Depending on the ingredients and the amount of liquid in the Instant Pot, it can take up to 30 minutes for the pressure to release naturally.

thanks for this recipe, it sounds delicious and i'd like to make it. however, not having an instant pot, i was wondering if you have directions for stovetop preparation? i'd appreciate it greatly.
Hi Marti, Here are the stove top instructions: https://www.veggiessavetheday.com/instant-pot-lentil-soup/#stove-top-instructions Enjoy the soup!
I made this today in my MEALTHY pot and it was fantastic it’s definitely a keeper I’m going to make it again thank you so much. just what I wanted for the record I omit oil and I did add a fresh lemon juice squeeze at the end.
I'm so happy to here it, Mandy! Love the lemon.
Melts in your mouth!!! I served it over brown basmati rice and added a dab of butter on top. My teenaged sons loved it too. This will be a family favorite!
I'm so glad everyone enjoyed it, Sabrina!
Is it still the same directions if made with red lentils?
Hi Val, red lentils won't work with this recipe because they will get really soft and disintegrate. But here is a red lentil soup recipe that I think you'll enjoy: https://www.veggiessavetheday.com/lentil-potato-soup/
