Coat the bottom of a large pot with the olive oil and place it over medium heat.
Once the oil is hot, add the onion, carrots, and celery. Sweat the vegetables for about 10 minutes, stirring frequently, until they begin to soften.
Stir in the garlic and cook it with the vegetables for about 1 minute, stirring constantly, until it becomes very fragrant.
Stir in the broth, lentils, potato, rosemary sprigs, and thyme leaves. Raise the heat and bring the liquid to a boil.
Lower the heat and let the soup simmer for 20 to 30 minutes, until the lentils and potato are tender.
Remove the pot from heat. Carefully remove the rosemary sprigs from the soup, then stir in the lemon juice and season it with salt and pepper to taste.
Serve.
