Ingredient Notes and Substitutions
This recipe is highly flexible. Consider these variations:
- Lentils: Brown lentils hold their shape; green or French lentils are also options. Red lentils will create a creamier soup.
- Vegetables: Add diced tomatoes, bell peppers, or spinach in the last minutes of cooking.
- Spices: Swap or add spices such as turmeric, smoked paprika, or cayenne for extra heat.
- Vinegar: Apple cider or sherry vinegar works if red wine vinegar is unavailable.
Step-by-Step Directions for Lentil Soup
- Sauté the aromatics.
Heat olive oil in a large Dutch oven over medium. Stir in chopped carrots, garlic, celery, and onion. Cook, stirring often, until the vegetables are soft and start to develop golden edges (5–7 minutes).
- Bloom the spices.
Add tomato paste, thyme, cumin, paprika, salt, and black pepper. Sauté until tomato paste darkens (2–3 minutes), which develops a richer, deeper flavor.
- Simmer with lentils and broth.
Pour in vegetable broth and lentils. Bring to a boil, reduce heat to medium-low, then cover and simmer for 35–40 minutes, until lentils are perfectly tender.
- Blend for creaminess.
Remove about 3 cups of soup and blend until almost smooth. Return to the pot and stir well. For more control over texture, use an immersion blender to partially puree the soup right in the pot.
- Finish and serve.
Stir in chopped parsley and red wine vinegar. Ladle into bowls and garnish with more parsley. Serve with rustic bread for dipping.
Expert Tips for the Best Lentil Soup
- Don’t skip sautéing: Sautéing vegetables and blooming the spices creates the soup’s base layers of flavor.
- Blending step: Blending a portion of the soup gives it a thicker, creamy body while maintaining plenty of texture.
- Brighten with vinegar: A splash of vinegar right at the end brings out the flavors and balances earthiness with a gentle tang.
- Use high-quality broth: The broth is the soup’s backbone. Opt for low-sodium vegetable broth to control salt levels, or homemade for best flavor.
- Leftovers improve: Like many soups, flavor deepens after a day in the refrigerator.

Customizing Flavor: Spices and Seasonings

Why Add Vinegar to Lentil Soup?
Finishing the soup with a tablespoon of red wine vinegar may seem unusual, but it serves an important purpose. The gentle acidity cuts through the starchiness of lentils and the richness of the soup, “brightening” each bowl so every flavor pops. The soup goes from merely good to irresistibly crave-worthy with this small but impactful step.

- Freezer: Lentil soup freezes beautifully for up to 3 months. Portion into containers, leaving room for expansion.
- Reheating: Thaw overnight in the refrigerator, then reheat gently on the stove, adding a splash of water as needed to loosen the texture.
Serving Suggestions
Lentil soup is incredibly versatile at the table. Try pairing it with:
- Crusty sourdough or whole-grain bread.
