Ingredients You’ll Need

  • 1 cup dry lentils (green, brown, or red)
  • 1 medium onion, chopped
  • 2 carrots, chopped
  • 2 celery stalks, chopped
  • 2 garlic cloves, minced
  • 1 tablespoon olive oil
  • 1 teaspoon salt
  • 1 teaspoon dried thyme
  • ½ teaspoon black pepper
  • 1 bay leaf (optional)
  • 6 cups water or vegetable/chicken broth

Optional add-ins:

  • Diced tomatoes
  • Spinach or kale
  • Potatoes or sweet potatoes
  • A splash of lemon juice
  • Pinch of red pepper flakes

Step‑By‑Step Instructions

  1. Sauté the veggies: Heat olive oil in a large pot over medium heat. Add onion, carrot, and celery. Cook until softened, about 5 minutes.
  2. Add aromatics: Stir in garlic, thyme, and black pepper. Cook for 1 minute until fragrant.
  3. Cook the lentils: Add lentils, water or broth, and bay leaf. Bring to a boil, then reduce heat and simmer for 25–30 minutes until lentils are tender.
  4. Season and adjust: Remove bay leaf, add salt, and taste. Adjust seasonings as needed. For a thicker texture, mash a few lentils or blend part of the soup.
  5. Add extras: Stir in any optional ingredients like greens or a splash of lemon juice just before serving.

Helpful Notes & Tips

  • Use low-sodium broth to control salt.
  • Lentils cook faster than other beans—no soaking needed.
  • Store leftovers in the fridge for up to 5 days or freeze in portions for later.
  • For even more flavor, try a pinch of cumin, paprika, or a bay leaf.

Recipe Variations

  1. Creamy lentil soup: Stir in coconut milk or light cream for a rich texture.
  2. Protein boost: Add cooked chicken, turkey sausage, or beef brisket.
  3. Grain addition: Stir in cooked quinoa, barley, or rice to make it heartier.

Serving Suggestions

  • Top with fresh herbs like parsley or cilantro.
  • Serve with crusty bread or toasted croutons.
  • A dollop of plain yogurt or shredded cheese adds extra creaminess.
