    Make the best Instant Pot lentil soup with this step-by-step recipe. It's quick, easy, delicious, and so comforting. Made with caramelized onion, juicy tomatoes, and spices such as turmeric and cumin, and plenty of vegetables, you'll love this cozy, soul-warming soup.

    A bowl of lentil soup

    Lentil soup is easy and convenient to make in the Instant Pot. This recipe is soul-warming, delicious, and so easy to make. It takes less than an hour and tastes great with a side of warm, crusty bread or side salad.

    Ingredients you'll need

    To get started, you'll need the following ingredients:

    • Oil: I use avocado oil
    • Garlic: minced or crushed
    • Yellow onion: finely diced
    • Celery: finely diced
    • Carrot: finely diced
    • Tomatoes: use canned or fresh
    • Dried lentils: rinsed and drained
    • Spices: including ground turmeric, cumin, salt, and black pepper
    • Water: You can also use vegetable broth
    • Lemon juice: preferably from fresh lemon

    How to make lentil soup in the Instant Pot

    1. Sauté garlic and onion: Click the "Saute" button on the Instant Pot. Add oil, garlic, and onion. Stir and cook until onions appear translucent, about 3-5 minutes.

    2. Add remaining ingredients: Add carrots, celery, tomatoes, lentils, turmeric, cumin, salt, and pepper. Stir and cook for another minute before adding the water. Pressing the "Cancel" button and placing the lid.

    3. Pressure cook: Close the Instant Pot lid, set the valve on "sealing", and cook on high pressure for 25 minutes. Once completed, let the pressure release naturally for 10 minutes before quick-releasing any remaining pressure. Carefully open the lid.

    4. Garnish and serve: Stir in the lemon juice and adjust seasoning, if needed. Garnish with parsley and serve.

    Serving suggestions

    While this lentil soup can be enjoyed on its own, here are some other ways to round out your meal:
