Ingredients
- 6tablespoons extra-virgin olive oil, plus more as needed
- 1large onion, diced
- 1½teaspoons kosher salt, plus more as needed
- 1quart chicken, beef or vegetable stock, preferably homemade
- 1cup brown or green lentils, rinsed
- 2thyme or rosemary sprigs
- 1 to 2garlic cloves, finely grated or pushed through a garlic press
- 1teaspoon white-wine, sherry or cider vinegar, or lemon or lime juice, plus more to taste
- ½cup thinly sliced radicchio, or red or green cabbage (optional)
- ½cup parsley leaves, chopped
- Toppings (see Tip)
Preparation
- Step 1
Heat ¼ cup oil in a medium pot over medium-high heat. Stir in onions and ½ teaspoon salt, and cook until onions start to brown at the edges, stirring frequently, 6 to 9 minutes.
- Step 2
Stir in stock, lentils, thyme and remaining 1 teaspoon salt. Bring to a simmer, cover, and cook until lentils are tender, 30 to 40 minutes. Discard thyme sprigs.
- Step 3
Stir in garlic, and remaining 2 tablespoons oil, and use an immersion blender to purée the soup to the desired consistency, keeping it chunky or making it smooth. (Alternatively, ladle it into a blender and blend in batches.) Stir in vinegar, then taste and add more salt and vinegar if needed.
- Step 4
In a small bowl, toss radicchio, if using, and parsley with a drizzle of oil and a sprinkle of salt. To serve, ladle soup into bowls and top with a small mound of radicchio and parsley, and/or any other garnishes you like.
- Dairy (yogurt or sour cream, crumbled feta or goat cheese, or grated Parmesan); spices (toasted cumin seeds, chile flakes, or garam masala); savory vegetables and tart fruit (cubed avocado, browned leeks or onions, grated citrus zest, diced tomatoes, diced orange or grapefruit segments, diced roasted red peppers or pickled jalapeños); or salty finishes (croutons, chopped cooked bacon, sliced olives, crumbled nori or dried seaweed snacks, sesame seeds and sesame oil) are all worthy toppings.

@Dr. J- the sauteing step is for the onion. With careful attention to the process a tablespoon (or two, max) would be enough to brown the onion, with a splash of broth or water added as needed during those 6-9 minutes. I almost never use as much oil as the mainstream servants of 'classical' technique do. Use common sense and the quantity that is needed for the task at hand.
Instead of the vinegar i usually add lemon juice at the end. And considerably more than suggested- as much as a couple tablespoons , or whatever i find in an entire lemon. It brightens up the taste wonderfully. A 1/4 teaspoon of cumin also works wonderfully with the lentils and lemon. Topped off with a swirl of good olive oil and a dollop of sour cream or thick yogurt.
Then perhaps you should make a recipe for low/no salt, fat soup and publish; don't eat this one, although it looks delicious.
This is a very tasty lentil soup and really easy. I use lemon juice instead of vinegar and serve over a boiled potato and garnished with the green cabbage. Served with a salad, this can be a nice lunch or a light supper.
This recipe is truly amazing! I now only make in double or triple batches. It is much easier than the other ones I have tried and tastes 10 times better. Low cost, low calorie, high fiber, high protein, freezes very well, and tastes great!
Made this when I had a bunch of lentils and no carrots or celery and not much fresh in my kitchen. This is now my go-to lentil soup. Loved the varieties of add-ons -- I ate this over several days, each meal testing out a new seasoning or topper, like sesame seeds, marsala, or cumin. Now that I have yogurt and lemon juice more to try. Very creamy, thanks to the olive oil. So, so delicious -- serve this to anyone who doesn't like lentil soup.
