Why This Lentil Soup Works

Carrots and celery add sweetness and an aromatic backbone that pairs beautifully with onions, garlic, and herbs.

This recipe balances:

Flavor: Onion, garlic, celery, carrots, bay leaf, thyme (or rosemary), and a finishing squeeze of lemon or vinegar.
Texture: Softened veggies, tender lentils, and a lightly thickened, spoonable broth.
Nutrition: Protein, fiber, iron, and micronutrients — perfect as a main or side.
