Green Lentil and Walnut Ragù
A slow-cooked ragù of green lentils and finely chopped walnuts with the depth of a meat sauce and none of the meat.
Why it works
Walnuts are what make this work. Chopped fine and cooked in from the start, they contribute fat and a savoury quality that lentils alone cannot reach, which is the usual reason vegetarian ragù disappoints. They also bring ALA, the plant omega-3, and are the nut with the most consistent cardiovascular evidence behind it. Green lentils hold their shape through a long cook where red ones dissolve, so the sauce has texture. The soffritto is not optional: twenty minutes of onion, carrot, and celery cooked slowly is where the sweetness comes from, and rushing it is why a quick version tastes thin. Cooked and cooled, the flavour deepens noticeably by day two.
Nut intake, and walnuts in particular, has consistent cohort support for cardiovascular outcomes. Legume-forward eating patterns are associated with lower all-cause mortality.
Ingredients
- 300 g dried green or Puy lentils
- 120 g walnuts, very finely chopped
- 1 onion, 2 carrots, and 2 celery sticks, all finely diced
- 4 garlic cloves, minced
- 2 tbsp tomato purée
- 400 g tin chopped tomatoes
- 700 ml vegetable stock
- 2 tsp dried oregano and 1 bay leaf
- 3 tbsp olive oil
- 1 tbsp balsamic vinegar
Method
- Warm the oil and cook the onion, carrot, and celery over medium-low heat for a full twenty minutes, stirring occasionally, until soft and sweet. This is the step that decides the depth of the sauce.
- Add the garlic and tomato purée and cook for two minutes until the purée darkens.
- Add the walnuts, lentils, tomatoes, stock, oregano, and bay, and simmer uncovered for 35 to 40 minutes until the lentils are tender and the sauce has thickened.
- Stir in the balsamic off the heat, which lifts everything, and taste for salt.
- Cool and portion. It thickens considerably in the fridge and is better on day two.
