New Year Lentil Soup with Vegetables and Lemon

Lentil soup has a natural place at the New Year table, where lentils are often valued for their hearty, sustaining character and association with good fortune. This version keeps the focus on green lentils simmered until tender with onion, carrot and celery, giving the broth body without turning it heavy. Garlic and bay leaves add a savoury backbone, while lemon stirred in at the end lifts the earthy lentils with a clean, fresh finish. Served hot with parsley, it is a practical vegan soup that feels nourishing enough for dinner but simple enough for batch cooking and easy reheating.

Why this recipe works

  • Simple savoury base: Softened onion, carrot, celery, garlic and bay leaves give the broth depth before the lentils are added.
  • Bright finish: Lemon juice added at the end lifts the earthy lentils and vegetables without making the soup taste sharp.
  • Keeps well: The soup refrigerates and freezes well, and can be loosened with a little extra stock when reheated.

Texture tips

  • For a thicker soup: Mash a few spoonfuls of lentils against the side of the pot, then stir them back in and simmer briefly.
  • Keep the lentils intact: Use a gentle simmer rather than a hard boil so the lentils soften evenly without breaking down too quickly.

Ingredient notes

  • Rinse the lentils: Rinsing dried lentils before cooking helps remove dust and any small debris.
  • Add lemon at the end: Stirring in the citrus after simmering keeps the flavour fresh and lets you adjust the brightness to taste.
  • Use fresh herbs to finish: Fresh parsley adds a clean herbal note that works best sprinkled over the hot soup just before serving.

Make-ahead tips

  • Refrigerate for the week: Cool the soup completely, then store it in a sealed container in the fridge for up to 4 days.
  • Freeze in portions: Portion the cooled soup before freezing so it defrosts easily for quick meals.
  • Loosen when reheating: Reheat gently in a saucepan and add a splash of vegetable stock if the soup has thickened in storage.

  1. Heat the olive oil in a large pot over a medium heat. Finely chop the onion, dice the carrots, and slice the celery, then add them to the pot with the salt and pepper. Cook for 8 to 10 minutes, stirring, until the vegetables are softened but not browned.
  2. Crush or finely chop the garlic and stir it in. Cook for 1 minute until fragrant.
  3. Rinse the lentils in a sieve, then add them to the pot along with the vegetable stock and bay leaves. Bring to the boil, then reduce to a gentle simmer and cook for 30 to 35 minutes, stirring occasionally, until the lentils are tender and the soup has thickened slightly.
  4. Remove and discard the bay leaves. Squeeze in the lemon juice, then taste and adjust with a little more salt and pepper if needed. Chop the parsley and serve the soup hot with parsley sprinkled over the top.
