Equipment

  • 1 Soup Pot
  • 1 Immersion blender

Ingredients
  

  • 1 medium onion diced
  • 3 cloves garlic minced
  • 3 carrots diced
  • 1 red bell pepper diced
  • 1 sweet potato (medium peeled & diced, about 2 cups / 250 g)
  • 1 Yukon Gold potato (small, diced about 1 cup / 150 g)
  • 1 ½ tsp ground cumin
  • 1 tsp smoked paprika (optional)
  • 1 tsp ground turmeric
  • 1 ½ cups red lentils (285 g, rinsed)
  • 4 cups vegetable broth (960 ml, low-sodium)
  • 1 to 2 cups water (240–480 m, add more as needed)
  • 1 bay leaf
  • Juice of 1 lemon (or to taste)
  • Salt & black pepper (to taste)
  • Fresh parsley or cilantro (chopped, for garnish)

Instructions
 

  • Dice onion, carrots, garlic, bell pepper, sweet potato, and Yukon Gold potato.
  • In a large soup pot, sauté onion, garlic, carrots, and bell pepper, with a splash of broth/water for 5–6 minutes.
  • Stir in cumin, smoked paprika, and turmeric. Cook for 1 minute.
  • Add lentils, sweet potato, and Yukon Gold potato. Stir well.
  • Pour in broth, water, and bay leaf. Bring to a boil, then reduce the heat to low, cover, and simmer for 25–30 minutes, or until the lentils and potatoes are tender.
  • Remove bay leaf. Blend part of the soup (or all of it) with an immersion blender for added creaminess, or leave it chunky.
  • Stir in lemon juice, season with salt and pepper.
  • Serve hot, garnished with fresh parsley or cilantro.

Notes

  • Adjust the water depending on how thick or soupy you like it. Start with 1 cup and add more as needed.
  • Red lentils cook quickly, so don’t overcook or they may turn mushy (unless you want a very creamy soup!).
  • For meal prep: portion into containers and freeze—this soup reheats beautifully.
  • Garnish with chili flakes or avocado slices for extra flair.
