Equipment

  • Large Dutch oven or heavy bottomed soup pot - 6-8 quart capacity; distributes heat evenly and prevents burning
  • Wooden spoon or silicone spatula - For stirring without scratching the pot
  • Sharp chef's knife - Makes vegetable prep much easier
  • Cutting board - Prefer a large one with a groove to catch juices
  • Measuring cups and spoons - For accurate measurements
  • Fine-mesh strainer - Essential for rinsing the lentils thoroughly
  • Immersion blender - (optional) For a completely smooth, creamy soup
  • Ladle - For serving
  • Citrus juicer - (optional) Makes getting fresh lemon juice easier

Ingredients
  

  • 2 tbsp olive oil - 30ml; extra virgin preferred for richer flavor
  • 1 large onion - about 1½ cups or 240g, diced; yellow or white onion
  • 3 garlic cloves - about 1 tablespoon or 9g, minced; fresh garlic essential
  • 2 medium carrots - about 1 cup or 130g, peeled and diced into ¼-inch pieces
  • 2 celery stalks - about ¾ cup or 100g, diced
  • 1½ cups red lentils - 300g, rinsed; look for the bright orange-red variety
  • 6 cups vegetable broth - 1.4L; low-sodium recommended
  • 1 can diced tomatoes with juice - 14.5 oz or 411g; fire-roasted adds smoky flavor
  • 2 tsp ground cumin - 4g
  • 1 tsp ground turmeric - 2g
  • ½ tsp smoked paprika - 1g; optional but highly recommended
  • ¼ tsp cayenne pepper - 0.5g; adjust to your heat preference
  • 1 tsp salt - 6g; start with less and adjust to taste
  • ½ tsp black pepper - 1g
  • 2 cups fresh spinach - 60g, roughly chopped; stirred in at the end
  • 2 tbsp fresh lemon juice - 30ml; brightens all the flavors

For Garnish

  • fresh cilantro or parsley - roughly chopped; for serving
  • Greek yogurt or sour cream - optional dollop for serving
  • olive oil - optional drizzle for serving
  • crispy chickpeas - optional; for crunch
  • red pepper flakes - optional; for extra heat

Instructions
 

  • Place red lentils in a fine-mesh strainer and rinse under cold running water for 30–45 seconds, swishing with your hand, until the water runs clear. Let drain completely while you prep the vegetables.
  • Dice the onion, carrots, and celery into uniform ¼-inch pieces; mince the garlic. Roughly chop the spinach and set aside for later.
  • Heat olive oil in a large pot over medium heat. Add onion and cook 5–7 minutes until softened, then add carrots and celery and cook another 4–5 minutes. Add garlic and stir for 30–45 seconds until fragrant.
  • Reduce heat to medium-low, add the cumin, turmeric, smoked paprika, and cayenne pepper, and stir continuously for 1 minute until spices coat all the vegetables and the aroma intensifies.
  • Stir in the rinsed lentils, then pour in the vegetable broth and entire can of diced tomatoes (with juice), scraping up any browned bits from the bottom. Increase heat to high and bring to a rolling boil.
  • Reduce heat to low, partially cover the pot, and simmer for 20–25 minutes, stirring every 5–7 minutes, until the lentils are completely soft and the soup is thick and creamy. Add broth if it becomes too thick.
  • Season with salt and pepper, then stir in the spinach and let it wilt for 1–2 minutes. Remove from heat and stir in the fresh lemon juice. Blend partially or fully with an immersion blender if desired.
  • Ladle into warm bowls and garnish with fresh cilantro or parsley, a drizzle of olive oil, and optional toppings like Greek yogurt or crispy chickpeas. Serve immediately with crusty bread or naan.

Notes

  • Always rinse red lentils until the water runs clear — skipping this step results in a gummy, starchy soup.
  • Use low-sodium vegetable broth so you can control the salt level yourself; the soup will taste flat if it's too salty.
  • Blooming the spices in oil for 1 minute before adding liquid is key — it transforms raw spice flavor into something warm and aromatic.
  • Add the lemon juice after removing the pot from heat to preserve its bright flavor; heat dulls citrus quickly.
  • The soup thickens significantly as it sits — when reheating, add ½–1 cup of broth or water to restore the right consistency.
  • For coconut curry variation: replace half the broth with coconut milk and add 1–2 tablespoons of curry powder.
  • Freezes beautifully for up to 3 months in airtight containers. Thaw overnight in the fridge and reheat with a splash of broth.
  • For Instant Pot: sauté aromatics and spices on sauté mode, add lentils and liquids, then cook on high pressure for 10 minutes with a 10-minute natural release.
  • When reheating leftovers, add a fresh squeeze of lemon juice to revive the bright, fresh-made flavor.
  • Use fresh garlic — pre-minced jarred garlic won't deliver the same punch of flavor.
