- 3 carrots (sliced)
- 2 stalks celery (sliced)
- 1 tablespoon tomato paste
- 3 cloves garlic (minced)
Spices
- 1 teaspoon Italian seasoning
- 1 teaspoon paprika
- 1/2 teaspoon cumin
- 2 bay leaves
- Black pepper (to taste)
Lentils and Liquid
- 2 cups dry green lentils (sorted and rinsed)
- 1 14.5 ounce can crushed tomatoes
- 4 cups vegetable broth
- 3-4 cups water
Finishing Touches
- 1 tablespoon fresh lemon juice
- 2 tablespoons chopped parsley (for garnish)
How to Make Classic Lentil Soup
Step 1: Prepare the Aromatics
Warm the olive oil in a dutch oven or large pot over medium heat. Add the diced onion and sauté for 2 to 3 minutes until translucent. Next, add the sliced carrots and celery, sautéing for an additional minute. Stir in the tomato paste until evenly mixed, then continue to sauté for another 2 to 3 minutes, stirring occasionally.
Step 2: Add the Spices
Add minced garlic along with Italian seasoning, paprika, cumin, bay leaves, and black pepper to the pot. Mix well and sauté for about 1 minute to toast the spices slightly.
Step 3: Simmer the Soup
Stir in the rinsed lentils, crushed tomatoes, vegetable broth, and 3 cups of water into the pot. Bring everything to a boil over high heat. Once boiling, reduce heat to medium and let it simmer for 20 to 30 minutes. Stir occasionally until lentils are tender. If the soup thickens too much, adjust by adding more water as needed.
Step 4: Finishing Touches
Remove bay leaves from the soup before serving. Stir in fresh lemon juice for brightness and season with salt and pepper according to your taste.

Common Mistakes to Avoid
When making Classic Lentil Soup, there are a few common pitfalls that can affect the outcome. Here are some mistakes to watch for:
- Skipping the soaking step: Not rinsing or soaking lentils can lead to a gritty texture. Always rinse and sort lentils before use.
- Overcooking vegetables: Cooking the mirepoix too long can make them mushy. Sauté them just until softened for the best flavor and texture.
- Neglecting spices: Adding spices at the wrong time can alter their flavors. Toast spices briefly with aromatics to enhance their taste.
- Ignoring liquid ratios: Using too little liquid may result in thick soup. Ensure you start with enough broth and adjust with water as needed.
- Forgetting to season: Under-seasoning can lead to bland soup. Taste and adjust seasoning towards the end of cooking for maximum flavor.
