🥕 What Is Lentil Soup?

At its core, lentil soup is a slow-cooked blend of lentils, vegetables, and aromatics. The magic lies in how the lentils gently break down to create a thick, velvety texture — naturally creamy without the need for dairy.

While every region has its version, from French potage de lentilles to Indian dal, the British adaptation often balances earthy lentils with carrots, onions, leeks, and a hint of thyme. It’s nutritious, affordable, and adaptable — a cornerstone of comforting, home-style cooking.

🌿 Key Ingredients for the Perfect Lentil Soup

1. Lentils:
   Red lentils cook down quickly and give a creamy texture, while green or brown lentils hold their shape for a rustic, chunkier soup.
   • Tip: Rinse lentils thoroughly to remove any dust and ensure even cooking.
2. Vegetables:
   Classic soup trio — onion, carrot, celery — forms the flavour base. Add leeks, potatoes, or parsnips for extra body.
3. Stock:
   Vegetable or chicken stock deepens flavour; homemade stock brings the best results.
4. Herbs and Spices:
   Thyme, bay leaf, and a touch of cumin or smoked paprika elevate the aroma.
5. Finishing Touches:
   A drizzle of olive oil, a squeeze of lemon juice, or a swirl of yoghurt can transform your bowl into something special.
