A velvety, warmly spiced Turkish red lentil soup finished with a sizzling paprika butter and a squeeze of lemon — one of the simplest, most nourishing soups in the world.
Mercimek corbasi is Turkish comfort at its most fundamental — a soup so deeply embedded in the culture that it appears on tables from humble home kitchens to the grandest restaurant menus without variation or apology. It is made from pantry staples, comes together in under an hour, and manages to be simultaneously light and profoundly satisfying.
Red lentils are uniquely suited to this preparation because they dissolve completely during cooking, producing a naturally thick, smooth soup without any blending trickery. Unlike green or brown lentils, they require no soaking and cook rapidly, making this an accessible weeknight dinner even on the most exhausted evenings. The onion and garlic are sautéed until genuinely golden rather than merely softened — this caramelisation adds sweetness and depth that distinguishes a great mercimek from an ordinary one.
The spicing is warm rather than hot: cumin, turmeric, and dried mint provide complexity without aggression. The transformative finishing touch is the paprika butter, known as tereyagi: butter melted in a small pan until foaming, then swirled with Turkish red pepper flakes and sweet paprika until fragrant and deeply red, then drizzled dramatically over the surface of each bowl at serving. The visual effect is striking and the flavour impact is significant — a silky, slightly smoky richness that elevates the soup from nourishing to extraordinary.

Notes
- The onion must be genuinely golden, not just translucent — take the time to caramelise it properly. This is the foundation of the soup’s flavour.
If the soup is too thick after blending, thin with hot water or additional broth until you reach your preferred consistency.
Turkish pul biber (Aleppo pepper) has a mild fruity heat and is worth seeking out at Turkish or Middle Eastern grocery stores. Regular red pepper flakes work as a substitute.
The soup is naturally vegan if you substitute good olive oil for the butter in the paprika finish.
Storage
Red lentil soup keeps exceptionally well, making it ideal for batch cooking. It will keep in the fridge for up to 5 days and in the freezer for 3 months. The soup thickens considerably overnight as the lentils absorb moisture — thin with broth or water when reheating and stir frequently over low heat. Make the paprika butter fresh each time you serve, as it loses its sizzle and colour when stored.
Serving Tips
Serve with warm flatbread or toasted sourdough for dipping and a squeeze of lemon stirred in just before eating. A small bowl of plain yoghurt on the side is traditional and balances the warmth of the spices beautifully. The soup is a complete, satisfying meal on its own but also works well as a starter before grilled fish or lamb.
