Ingredients
Vegetables and Aromatics
- ¼ cup extra virgin olive oil
- 1 medium yellow onion, small diced
- 2 medium carrots, small diced
- 2 celery ribs, small diced
- 3 to 4 cloves of garlic, minced
- 3 leaves kale, stemmed and sliced
Herbs and Spices
- 2 tablespoons tomato paste
- 2 teaspoons cumin
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1 teaspoon dried thyme
- Kosher salt and freshly ground black pepper, to taste
Liquids and Legumes
- 1 (28-ounce) can fire-roasted diced tomatoes
- 6 cups low-sodium vegetable broth
- 1 cup green or brown lentils
- 1 lemon, juiced (about 3 tablespoons juice)
Instructions
- Prepare the Vegetables: Heat the extra virgin olive oil in a large pot over medium heat. Add the diced onion, carrots, and celery, and cook until softened, about 5 to 7 minutes, stirring occasionally.
- Add Garlic and Spices: Stir in the minced garlic, tomato paste, cumin, oregano, basil, thyme, salt, and pepper. Cook for an additional 1 to 2 minutes until fragrant, ensuring the tomato paste is well incorporated.
- Add Tomatoes and Broth: Pour in the fire-roasted diced tomatoes with their juices and the vegetable broth. Stir to combine all ingredients thoroughly.
- Add Lentils and Simmer: Add the green or brown lentils to the pot. Bring the mixture to a boil, then reduce heat to low. Cover and let the soup simmer gently for about 30 to 40 minutes, or until lentils are tender.
- Add Kale and Finish Cooking: Stir in the sliced kale leaves and continue to simmer for an additional 5 minutes until the kale is wilted and tender.
- Season and Add Lemon Juice: Adjust seasoning with additional salt and pepper as needed. Stir in the freshly squeezed lemon juice to brighten the flavors.
- Serve: Ladle the soup into bowls and serve warm. This soup pairs well with crusty bread or a simple green salad for a full meal.
Notes
- For a spicier variation, add a pinch of red pepper flakes when adding the spices.
- Lentils do not require soaking, making this recipe quick to prepare.
- You can substitute kale with spinach or Swiss chard if preferred.
- Leftovers keep well refrigerated for up to 4 days and freeze great for up to 3 months.
- Use low-sodium broth to better control the salt content.
