- 2 stalks celery (chopped)
- 1 medium yellow onion (diced)
- 4 cloves garlic (minced)
- 6 cups vegetable stock

How to Make Lemon Lentil Soup
Step 1: Sauté the Vegetables
Heat the oil in a large stock pot over medium heat. Add the diced onion, chopped celery, and sliced carrots. Cook while stirring frequently until the vegetables are soft and the onions are translucent, about 3-4 minutes. Then add the minced garlic and cook for another minute until fragrant.
Step 2: Simmer the Soup
Pour the vegetable stock over the sautéed vegetables. Add the red lentils, bay leaves, turmeric, and cumin; stir well. Increase heat to medium-high to bring the soup to a boil. Once boiling, reduce heat to medium-low to let it simmer covered for 12-15 minutes until lentils are soft.
Step 3: Add Lemon Flavor
Remove the lid from the pot. Stir in lemon juice, lemon zest, salt, and black pepper into the soup mixture.
Step 4: Blend for Creaminess
Transfer about 2 cups of soup to a blender. Blend on high until smooth then pour it back into the pot; stir well to combine. Alternatively, use an immersion blender to partially blend until you reach your desired consistency.
Step 5: Final Touches
If using spinach or kale, add it now and cook for an additional 2-3 minutes until wilted. Taste your soup one last time and adjust salt and pepper as needed before serving hot topped with fresh parsley or cilantro.

- Bold Flavoring: Always taste as you go! Adjust seasoning gradually to achieve your ideal flavor profile.
- Fresh Ingredients: Use fresh vegetables and herbs for the best flavor and nutritional benefits.
- Texture Matters: Blend part of the soup for creaminess while leaving some lentils whole for texture.
- Acid Balance: Adding lemon juice at the end preserves its bright flavor; don’t add it too early in cooking.

Best Side Dishes for Lemon Lentil Soup
Pairing side dishes with your Lemon Lentil Soup can make your meal more enjoyable and filling. Here are some suggestions that complement the flavors beautifully.
- Quinoa Salad: A refreshing quinoa salad adds protein and fiber, enhancing your meal’s nutritional value.
- Roasted Vegetables: Seasonal roasted vegetables bring sweetness and depth, which balance the soup’s acidity.

- Coleslaw: A tangy coleslaw brings crunch and zest, providing contrast to the smoothness of the lentil soup.
Common Mistakes to Avoid
Making Lemon Lentil Soup can be simple and rewarding, but there are a few common pitfalls to watch out for.
- Ignoring the vegetable prep: Not chopping the vegetables uniformly can lead to uneven cooking. Ensure all pieces are similar in size for consistent texture.
- Overcooking the lentils: Lentils that are cooked too long turn mushy. Keep an eye on them and check for doneness around the 12-minute mark.
- Skipping seasoning adjustments: Tasting your soup before serving is crucial. Always adjust salt and pepper to enhance flavors.
- Not blending enough: For a creamier texture, blend part of the soup. If you skip this step, the soup may be too chunky for some preferences.
- Neglecting fresh herbs: Failing to add fresh parsley or cilantro at the end diminishes flavor. Always top your soup with fresh herbs just before serving.
