Ingredients

  • 1 cup brown or green lentils, rinsed and drained
  • 1 medium onion, finely chopped
  • 2 cloves garlic, minced
  • 2 medium carrots, diced
  • 2 celery stalks, diced
  • 1 medium zucchini, diced
  • 1 cup green beans, chopped into 1-inch pieces
  • 1 can (14.5 oz) diced tomatoes, with juices
  • 4 cups vegetable broth (low sodium preferred)
  • 1 tablespoon olive oil
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon dried thyme
  • 1/2 teaspoon black pepper
  • 1 teaspoon salt, or to taste
  • 1 bay leaf
  • 2 cups fresh spinach, roughly chopped
  • Juice of half a lemon (optional, for brightness)

Equipment

  • Instant Pot or any electric pressure cooker
  • Measuring cups and spoons
  • Cutting board and sharp knife
  • Wooden spoon or silicone spatula for stirring
  • Ladle for serving
  • Soup bowls for serving

Instructions

  1. Prepare the vegetables: Rinse and chop all your vegetables as described above. Rinse the lentils thoroughly under cold water and drain.
  2. Sauté the aromatics: Turn your Instant Pot to the ‘Sauté’ setting. Add the olive oil, then toss in the chopped onion, garlic, carrots, and celery. Cook for about 4-5 minutes, stirring occasionally until the onions are translucent and the vegetables start to soften.
  3. Add the spices: Sprinkle in the ground cumin, smoked paprika, dried thyme, salt, and black pepper. Stir well to coat the vegetables and release the spices’ aromas, about 1 minute.
  4. Add lentils and liquids: Pour in the rinsed lentils, diced tomatoes with their juices, and vegetable broth. Toss in the bay leaf and give everything a good stir to combine.
  5. Pressure cook: Seal the Instant Pot lid and set it to ‘Pressure Cook’ or ‘Manual’ on high pressure for 15 minutes. Make sure the valve is set to sealing.
  6. Natural release: Once the cooking time is up, allow the pressure to release naturally for 10 minutes, then carefully do a quick release to release any remaining pressure.
  7. Add green vegetables and lemon: Open the lid and stir in the chopped zucchini, green beans, and fresh spinach. The residual heat will cook these tender-crisp. If you prefer softer vegetables, you can use the ‘Sauté’ function for 3-4 minutes. Squeeze in the lemon juice for added brightness and stir well.
  8. Final taste adjustment: Taste your soup and adjust seasoning if needed—add more salt, pepper, or a pinch of chili powder for heat.
  9. Serve and enjoy: Ladle the soup into bowls and serve warm. It pairs wonderfully with crusty bread or a side salad.

Tips & Variations

“For a creamier texture, stir in some coconut milk or blend a portion of the soup before adding the vegetables.”

Feel free to experiment with the vegetables — sweet potatoes, kale, or bell peppers are excellent additions. If you prefer red lentils, reduce the cooking time to about 8 minutes as they cook faster.

For an extra flavor boost, add a splash of soy sauce or a teaspoon of smoked chili powder from this Chilli Powder Recipe Vegan: Easy Homemade Spice Blend.

To make this soup even more filling, serve it alongside recipes like A to Z Vegetarian Recipes for Every Meal and Occasion or add a side of whole grain bread from the Ancient Grains Vegetarian Recipes for Healthy Delicious Meals collection.
