An easy Italian style lentil soup that is packed with flavor due to ‘gremolata’: a mixture of parsley, lemon zest, garlic, and olive oil.
When cleaning out the cupboards, we came across a pack of black beluga lentils. They tend to glisten when they are – briefly – cooked, which makes them look like beluga caviar. If you cannot find these, French green lentils (Puy lentils) would be a good substitute in this recipe (based on the one I found over at seriouseats.com).
The recipe
For the gremolata
- 2 tablespoons grated zest
- 20g / ½ cup chopped fresh parsley leaves
- 6 medium cloves garlic, minced
- 60ml / ¼ cup extra-virgin olive oil
For the lentil soup
- 60ml / ¼ cup extra-virgin olive oil
- 1 large leek, white and pale green parts only, finely chopped
- 1 medium onion, finely diced
- 1 large carrot, peeled finely diced
- 2 stalks celery, finely diced
- 450g / 1 pound dried black beluga lentils
- 2 bay leaves
- 2lt / 2 quarts vegetable stock
- 30ml / 2 tablespoons juice from 1 to 2 lemons
- 1 teaspoon of crushed cumin seeds
- Combine the lemon zest, parsley, garlic and olive oil in a medium bowl and stir with a fork until fully combined. Season to taste with salt and pepper and presto!
- Heat the olive oil in a large Dutch oven over medium-high heat until shimmering and start your soffrito by adding the leek, onion, carrot, and celery to the pan and cook it for about 5 minutes until just softened.
- Add half of the gremolata and cook for 1 minute, until fragrant.
- Add lentils and stir until coated in oil. Then add the bay leaves and stock and bring it to a boil.
- Once boiling, bring down the heat to just keep it at a simmer, cover with the lid slightly ajar, for 1 hour until the lentils are completely tender (the lentils should be fully covered at all times so add some adding water if necessary)
- Use a food processor (or immersion blender) to get the consistency you prefer. I roughly processed about ¾ of the soup in 2 batches and mixed it back into the remaining soup.
- Whisk in lemon juice and the cumin seeds and season to taste.
- Serve, drizzling the remaining gremolata on top of each bowl.
What worked and what didn’t:
It is amazing what the gremolata does to this lentil soup. It already gives a boost of freshness of the soup when cooking and it finishes off the soup brilliantly as a “dressing”. Lentil soups often tend to turn out really dense, but this one is really light and moreish.
Recipe accuracy:
The recipe is accurate, easy to follow and serves 4.
Suggested tweaks:
A topping of crispy fried cubes of bacon comes to mind; a classic combination with lentils.
Verdict: 9/10; Will definitely be made again
