Ingredients

Vegetables and Aromatics

  • 1 medium yellow onion (diced)
  • 2 medium celery stalks (diced)
  • 2 medium carrots (diced)
  • 4 garlic cloves (pressed)
  • 3 cups chopped curly kale leaves (or spinach)

Lentils and Liquids

  • 1.5 cups dry red lentils
  • 4 cups chicken bone broth (or vegetable or chicken broth)
  • 1 cup water
  • 1/2 cup low sodium tomato sauce

Other Ingredients

  • 2 tbsp olive oil
  • 1 tsp ground cumin
  • Salt and black pepper to taste

Instructions

  1. Sauté Vegetables: In a large pot over medium heat, heat the olive oil. Add the diced onion, carrots, and celery, sautéing until they are soft and fragrant, about 5 minutes. Then add the pressed garlic and cook for an additional minute until fragrant.
  2. Simmer Lentils: Add the chicken bone broth, red lentils, and ground cumin to the pot. Cover and lower the heat to bring the soup to a gentle simmer. Let it cook for about 25 minutes, allowing the lentils to soften and the flavors to meld.
  3. Finish and Season: After the lentils are cooked, stir in the low sodium tomato sauce, additional water, and chopped kale leaves. Season with salt and black pepper according to your taste. Cook for a few more minutes until the greens wilt and the soup is heated through.

Notes

  • You can substitute kale with spinach or other leafy greens as preferred.
  • Use vegetable broth to make the soup vegetarian or vegan.
  • Adjust the thickness by adding more or less water based on your preference.
  • For a spicier version, add a pinch of cayenne pepper or chili flakes.
  • Leftovers keep well refrigerated for up to 3 days and freeze perfectly for up to 2 months.
