French Lentil Soup

This classic French lentil soup is a nutritious, plant-based staple that relies on simple pantry ingredients to deliver a deep, savoury flavour. By sautéing aromatic onions, celery, and carrots until golden, you create a rich base that perfectly complements the earthy profile of the lentils. The addition of tinned tomatoes adds a subtle acidity, while a final splash of balsamic vinegar provides a sophisticated lift to this comforting vegan dish.

Ideal for meal prep or a healthy midweek dinner, this soup is naturally high in fibre and plant-based protein. Blending a small portion of the soup creates a velvety texture without the need for cream, making it a lighter choice for those seeking a heart-healthy meal. Serve it piping hot with a slice of crusty sourdough bread for the ultimate homemade lunch.

Ingredients for French Lentil Soup

  • 3 tablespoons extra–virgin olive oil

  • 475ml chopped onions

  • 1 cup chopped celery stalks plus chopped celery leaves for garnish

  • 1 cup chopped carrots

  • 2 garlic cloves, chopped

  • 950ml (or more) vegetable broth

  • 300ml lentils, rinsed, drained

  • 1 14 1/2–ounce can diced tomatoes in juice

  • Balsamic vinegar (optional)

How to make French Lentil Soup

Heat oil in heavy large saucepan over medium–high heat. Add onions, celery, carrots, and garlic; sauté until vegetables begin to brown, about 15 minutes. Add 950ml broth, lentils, and tomatoes with juice and bring to boil. Reduce heat to medium–low, cover, and simmer until lentils are tender, about 35 minutes.

Transfer 475ml soup (mostly solids) to blender and puree until smooth. Return puree to soup in pan; thin soup with more broth by 60ml fuls, if too thick. Season with salt, pepper, and a splash of vinegar, if desired. Ladle soup into bowls. Garnish with celery leaves.
