Vegan Instant Pot Lentil Soup
Truth be told, I could eat this kind of food all year long. In fact, I made this Instant Pot Lentil Soup a couple of times over the summer to recipe test it for the blog. I can attest that it's definitely a recipe that can hold its own no matter what the weather!
But now that there's a chill in the air, this soup is tasting better than ever.
Easy Pantry Recipe
One of the reasons I love this recipe is that you probably already have all, if not most, of the ingredients in your pantry or refrigerator.
There's no meat to defrost. No spices you'll need to go out and buy (and probably only use once or twice). Just common veggies, green lentils, broth (I use vegetable broth but you can use chicken broth if that's what you have), and common spices. Easy peasy and SO fast and delicious!
A healthier, heartier vegan and vegetarian soup
This is a super hearty vegetarian recipe that I think you'll find the carnivores in your life will enjoy as well. Because there's no dairy, it's also one of my favorite vegan recipes.
Because lentils contain virtually no fat but are high in fiber, they tend to fill you up without adding unnecessary calories to your meal. Studies also show that lentils, high in magnesium as well as fiber, have been shown to help reduce inflammation.
What is the difference between green lentils and red lentils?
Green lentils are also packed with great vitamins and minerals. According to the USDA, a half cup of dried green lentils provides 24g protein, 10g fiber, 80mg calcium, and 4mg iron.
I use green lentils for this recipe because they tend to hold up and retain their shape during the cooking process. Red lentils, on the other hand, can get mushy when cooked for a while.
Can lentil soup be frozen?
Yes! Keep this lentil soup in an airtight freezer-friendly container in your freezer for up to 3 months.
What to serve with vegan lentil soup
While eating bowlfuls of this Instant Pot Lentil Soup on its own makes for a perfectly acceptable full meal, here are some ideas for side dishes to serve with it:
- simple green salad
- steamed or roasted broccoli
- flatbread
- smashed potatoes

I've been making and eating a lot of lentil soup lately, which I love because it's so healthy and vegetarian. But I need to try out different recipes of lentil soup to mix things up at dinner.
