Red lentil soup is the weeknight hero you never knew you needed. Red lentils cook in about 20 minutes and dissolve into a naturally creamy puree without any blending required, though a quick blitz makes it extra silky.
Spiced with cumin, turmeric, and a squeeze of lemon, this soup is bright, warming, and packed with plant-based protein. It costs almost nothing to make and feeds a crowd.
