Lentil Soup

💡 Pro Tips

• ✓
  Soak dried lentils for 30 minutes in room temperature water before cooking to reduce cooking time by 15-20 minutes and decrease oligosaccharides (which cause digestive discomfort) by up to 25%.timing30 minutes soaking | 15-20 minute reduction
• ✓
  Add acidic ingredients (vinegar, lemon juice, tomatoes) only in the final 5 minutes of cooking; acids denature pectin in lentil skins and prevent softening if added early, leaving centers undercooked.timingFinal 5 minutes only
• ✓
  Maintain a 3:1 water-to-lentil ratio by weight and simmer at 180-190°F rather than boiling—this prevents violent agitation that breaks down lentils into mush while maintaining even hydration across all legumes.technique3:1 ratio | 180-190°F
• ✓
  Use green or French lentils (Puy) instead of red lentils if you want texture to survive cooking; red varieties contain 30% less tannins and pectin, causing them to disintegrate into purée within 20-25 minutes.ingredient20-25 minute disintegration window for red lentils
• ✓
  Salt the soup only after lentils are 90% tender (at ~35-40 minutes); sodium chloride competes with calcium for pectin bonding sites in cell walls, delaying softening by 10-15 minutes if added too early.timing35-40 minutes | 10-15 minute delay if salted early
