The leeks I got were huge, so I only used two of them. If you'd like to know a good way to clean those dirty things, check out my About Leeks post.
Just a note, it took me longer than 20 minutes to put this together. I'm not sure why, but plan for some extra time. Also, next time I will double the lentils. It's more vegetable than lentil, not that there's anything wrong with that, but the name is a bit misleading. I forgot the parmesan at the end...
Delicious and satisfying, and healthy with all the dark green leafy and dark orange vegetables. We will eat this soup a lot.
Winter Lentil Soup
Hands-on Time: 20 minutes
Total Time: 1hour
- 1 tablespoon olive oil
- 4 leeks (white and light green parts), cut into 1/4-inch-thick half-moons
- 1 28-ounce can whole tomatoes, drained
- 2 sweet potatoes, peeled and cut into 1/2-inch pieces
- 1 bunch kale, thick stems removed and leaves cut into 1/2-inch-wide strips
- 1/2 cup brown lentils
- 1 tablespoon fresh thyme
- Kosher salt and black pepper
- 1/4 cup grated Parmesan (1 ounce; optional)
1. Heat the oil in a large saucepan or Dutch oven over medium heat. Add the leeks and cook, stirring occasionally, until they begin to soften, 3 to 4 minutes. Add the tomatoes and cook, breaking them up with a spoon, for 5 minutes.
2. Add 6 cups water and bring to a boil. Stir in the sweet potatoes, kale, lentils, thyme, 1 ½ teaspoons salt, and ¼ teaspoon pepper. Simmer until the lentils are tender, 25 to 30 minutes.
3. Spoon into bowls and top with the Parmesan, if using.
Tip: Basic brown lentils retain their shape better during cooking than pricier red and yellow lentils, so they're terrific for soups. Or you can substitute green lentils, which taste slightly peppery.
