Why This Soup Belongs in Your Weekly Rotation
Few meals are as reliably comforting, nutritious, and easy to make as a well-spiced red lentil soup. Red lentils cook quickly without soaking, absorb flavours beautifully, and provide an excellent source of plant-based protein and fibre. Paired with anti-inflammatory turmeric, gut-friendly ginger, and a bright hit of lemon, this soup is as functional as it is delicious.
It's naturally vegan, gluten-free, and freezes exceptionally well — making it ideal for batch cooking.
Ingredients (Serves 4)
- 250g red lentils, rinsed
- 1 large onion, diced
- 4 garlic cloves, minced
- 1 tablespoon fresh ginger, grated
- 2 medium carrots, diced
- 400g tin chopped tomatoes
- 1.2 litres vegetable stock
- 2 teaspoons ground turmeric
- 1 teaspoon ground cumin
- 1 teaspoon smoked paprika
- ½ teaspoon ground coriander
- Juice of 1 lemon (plus zest for extra brightness)
- 2 tablespoons olive oil
- Salt and black pepper to taste
- Large handful of fresh coriander or flat-leaf parsley, to finish
- Optional: a pinch of dried chilli flakes for heat
Method
- Sauté the aromatics: Heat olive oil in a large pot over medium heat. Add the diced onion and cook for 5–6 minutes until softened and lightly golden. Add the garlic and grated ginger and cook for a further minute, stirring constantly.
- Add the spices: Stir in the turmeric, cumin, smoked paprika, and ground coriander. Cook for 60 seconds, letting the spices bloom in the oil. This step is important — it deepens the flavour significantly.
- Add vegetables and lentils: Add the diced carrots and stir to coat in the spiced oil. Add the rinsed red lentils, chopped tomatoes, and vegetable stock. Stir well to combine.
- Simmer: Bring to a boil, then reduce to a gentle simmer. Cook uncovered for 20–25 minutes, or until lentils are completely soft and have begun to break down into the broth.
- Blend (optional): For a smoother texture, use a hand blender to partially blend the soup, leaving some texture. For a chunkier result, skip blending entirely.
- Season and brighten: Stir in the lemon juice and zest. Season generously with salt and pepper. Taste and adjust — lentil soup often benefits from more lemon than you think.
- Serve: Ladle into bowls and top with fresh coriander or parsley, a drizzle of extra virgin olive oil, and optional chilli flakes.
