  • cups dried red lentil
  • 5 cups broth
  • tablespoon olive oil
  • cups chopped onion
  • 1 tablespoon minced garlic
  • 1 teaspoon turmeric powder
  • teaspoon ground cumin
  • ½ teaspoon ground coriander


  • Juice of half a lemon
  • salt and pepper, (to taste)


  • Press the “Sauté” function key then “Normal”. When Instant Pot displays “Hot”, heat oil and cook onion for about 6 minutes or until translucent. Add garlic, cumin, coriander, turmeric, stir for 1 minute.
  • Stir in the red lentils, and broth. Be sure to scrape the bottom of the pot to keep the pan clear and nothing is stuck on it to prevent burning.
  • Secure the lid and set it to manual on high for 8 minutes. After the cooking cycle finished, quickly release the pressure. 
  • Open the lid. Stir the soup. No blending necessary unless you want it to be really smooth. Adjust seasoning with salt and pepper if necessary. If the broth is too thick, add about 1 cup of warm broth and stir to combine.
    Serve with lemon juice.




  1. In a large dutch oven. Cook onion in oil over medium heat, stirring occasionally, until softened, about 6-7 minutes.
  2. Add garlic, cumin, coriander, and turmeric. Cook and keep stirring for about 1 minute.
  3. Add red lentil and broth (use about 7 cups). Simmer, partially covered, stirring occasionally to prevent lentils from sticking to the base of the pan, until lentils are very soft and falling apart for about 30 minutes. Add more broth or water if necessary.
  4. Adjust seasoning with salt and pepper if necessary! Serve with the optional lemon juice if necessary! Enjoy!
