Instructions
Making this High Protein Lentil Soup is simple and straightforward:
First, heat the olive oil in a large pot over medium heat. Add the chopped onion, celery, and carrots. Season lightly with salt, pepper, and garlic powder, and sauté until the vegetables are softened.
Next, grate or mince two cloves of garlic and add them to the pot. Cook for another minute until fragrant.
While the vegetables are cooking, rinse the lentils thoroughly and set them aside.
Pour the water into the pot, then add the lentils. Stir everything together well.
Add the bay leaf and the remaining garlic clove (whole) to the soup. Season with additional salt, pepper, and garlic powder to taste.
Bring the soup to a boil, then reduce the heat and let it simmer gently. Cook until the lentils are soft and tender, about 25–35 minutes.
Taste and adjust seasoning if needed before serving.
