How to Make Lemon Lentil Soup
Step 1: Sauté the Vegetables
Heat the oil in a large stock pot over medium heat. Add the onion, celery, and carrots. Cook while stirring frequently until the vegetables are soft and the onions are translucent, about 3-4 minutes. Add the minced garlic and cook for another minute until fragrant.
Step 2: Combine Ingredients
Pour the vegetable stock over the sautéed vegetables. Add the red lentils, bay leaves, turmeric, cumin, salt, and pepper. Stir well to combine. Increase heat to medium-high until boiling. Once boiling, reduce heat to medium-low to simmer. Cover and let simmer for 12-15 minutes until lentils are soft.
Step 3: Add Lemon Flavor
Remove the lid from the pot. Stir in the lemon juice, lemon zest, salt, and black pepper to enhance flavor.
Step 4: Blend for Creaminess
Transfer 2 cups of soup to a blender. Blend on high until smooth then return it back into the pot. Alternatively, use an immersion blender to partially blend the soup to reach your desired consistency.
Step 5: Add Greens & Serve
If using spinach or kale, add it now and cook for another 2-3 minutes until wilted. Taste your soup; adjust seasoning if necessary. Serve hot topped with fresh cracked black pepper and garnish with parsley or cilantro.

Common Mistakes to Avoid
When making Lemon Lentil Soup, avoiding common pitfalls can lead to a more flavorful dish. Here are some mistakes to steer clear of:
- Ignoring the aromatics: Failing to sauté onions, garlic, and vegetables can result in a bland soup. Always start by cooking these ingredients until they’re soft and fragrant.
- Overcooking the lentils: If you let the lentils cook too long, they may become mushy. Keep an eye on them and remove from heat as soon as they’re tender.
- Not seasoning adequately: Skipping or skimping on salt will leave your soup flat. Taste as you go and adjust the seasoning at different stages of cooking.
- Neglecting acidity: Forgetting to add lemon juice at the end can diminish flavor depth. Stir in fresh lemon juice just before serving for brightness.
- Using expired stock: Old vegetable stock can negatively affect the taste of your soup. Always check for freshness before using store-bought or homemade stock.
