Zuppa di Lenticchie alla Toscana (Tuscan Lentil Soup)
Why this recipe works
- Simple flavour base: Onion, carrot and celery are softened first, giving the broth a rounded savoury foundation before the lentils are added.
- Naturally hearty: Green lentils thicken the soup as they cook, creating a filling texture without cream or dairy.
- Good for leftovers: The soup keeps well, reheats gently and can be loosened with a little stock if it thickens in the fridge or freezer.

Ingredient notes
- Use lentils that hold their shape: Green lentils are a good choice because they become tender without collapsing too quickly, keeping the soup rustic rather than puréed.
- Rosemary options: Fresh rosemary gives the cleanest herbal flavour, but dried rosemary can be used sparingly as it is more concentrated.
Texture tips
- Keep the simmer gentle: A steady, gentle simmer helps the lentils cook evenly while keeping some shape and bite.
- Loosen before serving if needed: Lentil soup thickens as it stands, so add a little extra stock or water when reheating if you prefer a looser broth.
Make-ahead tips
- Make ahead for easy lunches: Cook the soup in advance, cool it completely and refrigerate in a sealed container for up to 4 days.
- Freezes well: Freeze cooled portions for up to 3 months, then defrost overnight in the fridge before reheating until piping hot throughout.
Authenticity notes
- Tuscan home-style approach: The recipe follows a familiar central Italian pattern: legumes, vegetables, tomato, herbs and olive oil cooked into a filling, unfussy soup.
- Serve with bread: Crusty bread is the natural accompaniment, useful for soaking up the tomato-rich broth and making the meal more substantial.

Ingredients
Instructions
- Heat the olive oil in a large pot over a medium heat. Finely chop the onion, carrot and celery, then add to the pot with a pinch of the salt and cook for 8 to 10 minutes until softened but not browned.
- Strip the rosemary leaves from the sprig and add them to the pot. Stir for 30 seconds until fragrant.
- Add the canned tomatoes, lentils and vegetable stock, then bring to a gentle simmer. Cook for 25 to 30 minutes, stirring occasionally, until the lentils are tender and the soup has thickened slightly.
- Season with the remaining salt and the black pepper. Serve hot, finishing each bowl with a small drizzle of olive oil from the measured amount if you like.
Recipe notes
Serving suggestions
This recipe pairs well with:
Tips
- Rinse the lentils in a sieve before cooking to remove any dust and help keep the broth clear.
- Keep the simmer gentle rather than boiling hard so the lentils turn tender without breaking down too quickly.
- If serving vulnerable groups, make sure the soup is reheated until piping hot throughout.
Substitutions
- Replace fresh rosemary with dried rosemary for a similar flavour; use less, as it is more concentrated.
- Replace vegetable stock with water for a lighter soup, then adjust the fine sea salt to taste.
Storage
- Refrigerate up to 4 days
- Cool completely, then refrigerate in a sealed container. Reheat gently in a saucepan over a medium-low heat, adding a splash of vegetable stock if it has thickened; freeze for up to 3 months and defrost overnight in the fridge before reheating until piping hot.
