Ingredients

Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large pot over medium heat. Add 1 cup diced onion and cook for 5 minutes until softened and translucent, stirring occasionally.
  2. Step 2: Add 1/2 cup diced carrots, 1/2 cup diced parsnips, and 1 cup diced potatoes to the pot. Cook for 5 minutes, stirring to coat vegetables in oil and soften edges.
  3. Step 3: Stir in 3 minced garlic cloves and cook for 1 minute until fragrant, being careful not to brown.
  4. Step 4: Add 1 cup rinsed green lentils, 4 cups vegetable broth, 1 tsp dried thyme, 1 bay leaf, and a pinch of salt and pepper. Bring to a boil, then reduce heat to low, cover, and simmer for 35-40 minutes until lentils and vegetables are tender.
  5. Step 5: Discard bay leaf. Season with additional salt and pepper to taste. Stir in 2 tbsp chopped fresh parsley before serving.
