Ingredients

• 2 tablespoons extra-virgin olive oil
• 1 large white onion, diced
• 2 carrots, diced
• 2 celery stalks, diced
• 4 cloves garlic, minced
• 6 cups vegetable or chicken broth
• 1¼ cups green or brown lentils, picked over and rinsed
• 1 (28-ounce) can fire-roasted diced tomatoes
• 2 bay leaves
• 1 tablespoon Italian seasoning
• ½ teaspoon crushed red pepper flakes (adjust to taste)
• 2 cups chopped kale or collard greens
• ½ cup chopped fresh basil, plus more for garnish
• Fine sea salt and freshly-ground black pepper, to taste
• Freshly-grated Parmesan cheese, for serving

Instructions

1. Sauté the vegetables
   In a large stockpot, heat olive oil over medium-high heat. Add the diced onion, carrots, and celery. Sauté for 6–7 minutes, stirring occasionally, until the onion becomes soft and translucent. Stir in the garlic and cook for another 1–2 minutes until fragrant.
2. Build the soup base
   Pour in the broth, then add the rinsed lentils, fire-roasted tomatoes, bay leaves, Italian seasoning, and crushed red pepper flakes. Stir well to combine. Bring the mixture to a boil.
3. Simmer
   Reduce the heat to medium-low, cover, and let the soup simmer for 25–30 minutes or until the lentils are tender. Stir occasionally to prevent sticking.
4. Add greens and season
   Remove the bay leaves. Stir in the chopped kale (or collard greens) and fresh basil. Simmer for another 2–3 minutes until the greens are wilted. Taste and adjust seasoning with salt, pepper, and extra herbs as desired.
5. Serve
   Ladle the soup into bowls and garnish with extra basil and a generous sprinkle of freshly grated Parmesan. Serve hot.
