Creating a delectable Classic Lentil Soup is easy. Here’s how to do it step-by-step:

1. Sauté Vegetables: In a large pot, heat the olive oil over medium heat. Add the diced onion, carrots, and celery. Cook until the vegetables soften, about 5-7 minutes.

1. Add Garlic and Spices: Stir in the minced garlic, cumin, thyme, and smoked paprika. Cook for about 1-2 minutes until fragrant.

1. Incorporate Lentils: Add the rinsed lentils to the pot and stir to combine with the vegetables.

1. Add Broth and Tomatoes: Pour in the vegetable broth and add the undrained canned tomatoes. Bring this mixture to a boil.

1. Simmer the Soup: Once boiling, reduce the heat to low and let the soup simmer for 30-40 minutes. Stir occasionally until the lentils are tender.

1. Add Greens: About 5 minutes before the soup is done, stir in the chopped spinach or kale, allowing it to wilt.

1. Season to Taste: Taste the soup, and add salt and pepper as needed. For an extra burst of flavor, add lemon juice if desired.

1. Serve: Ladle the soup into bowls, and garnish with freshly chopped parsley.

This step-by-step guide ensures that you create a filling and delightful Classic Lentil Soup effortlessly.
