Instant Pot Lentil Soup is an easy, healthy recipe for lentil soup made in the electric pressure cooker. Can be made vegetarian/vegan.
Lentils are a favorite at our house. They are inexpensive, hearty, and healthy.
They are a great way to stretch meat, but they’re also delicious all on their own in everything from soups to sauce.
This Instant Pot Lentil Soup is easy to make, and the few simple ingredients in the soup pack a lot of flavor.
This soup can also be made with vegetable broth, which makes it a great Meatless Monday dinner.
How to make Instant Pot lentil soup
Add the onion, carrots, and celery into the hot inner pot. Cook, stirring regularly, until the vegetables have softened.
Add the garlic, seasoning, salt, and pepper. Stir in to combine.
Stir in the lentils and broth.
Add the tomato paste but don’t stir in. Seal and cook.
Release remaining pressure and uncover. Stir in fresh spinach.
Tips
- Vegetarian/Vegan: To make this soup vegetarian/vegan, simply use vegetable broth in place of the chicken broth.
- Lentils: You can use green lentils in place of the brown lentils in this recipe.
- Veggies: Feel free to add more veggies if you prefer.
- Balsamic vinegar: The balsamic vinegar adds a bit of sweetness and acidity to the soup (helps to brighten up the soup). If you prefer, you can use another type of vinegar (like red wine).

Proportions and timing suggestions were perfect. I doubled the recipe and had French blue lentils on hand. I added extra olive oil and some lemon juice at the end. I also added some preboiled dandelion greens we had picked the day before from our garden- Chopped finely when serving. So thick and flavourful, lentils were perfectly cooked.
