Lemon Lentil Soup
Equipment
- 1 Medium pot (stovetop method)
- 1 Instant Pot (optional for pressure cooking)
- Measuring spoons and cups
- Knife and cutting board
Ingredients
- 1 tbsp Olive oil
- 3 cloves Garlic minced or pressed
- 1 cup Red lentils rinsed
- 1/4 tsp Salt adjust to taste
- 1/4 tsp Black pepper
- 1/4 tsp Garlic powder
- 1/4 tsp Paprika
- 1/4 tsp Turmeric
- 5 cups Vegetable broth
- 1 Lemon zest and juice
Instructions
- Prepare Aromatics: Peel and mince or press the garlic cloves. Heat 1 tablespoon of olive oil in a medium-sized pot over medium heat. Once the oil is warm, add the garlic. Sauté gently for 2–3 minutes, stirring constantly to prevent burning. The goal is for the garlic to release its aroma and turn lightly golden without browning, forming a flavorful base for the soup.
- Toast the Lentils: Add 1 cup of red lentils to the pot with the garlic. Stir for 1–2 minutes to lightly toast the lentils in the garlic-infused oil. Toasting enhances the lentils’ nutty flavor and helps them maintain their shape as they cook. Keep the heat at medium to avoid sticking or burning.
- Season with Spices: Sprinkle in 1/4 teaspoon each of salt, black pepper, garlic powder, paprika, and turmeric. Stir thoroughly to coat the lentils and garlic evenly. These spices provide warmth, depth, and a gentle color to the soup. Pause for a moment to enjoy the fragrant aroma—the flavor foundation is now established.
- Add Broth and Simmer: Pour 5 cups of vegetable broth into the pot. Stir to combine all ingredients, then increase heat until the liquid gently boils. Once boiling, reduce heat to medium-low, cover the pot with a lid, and allow the soup to simmer for about 15 minutes. Stir occasionally, allowing the lentils to soften and absorb the broth. For a creamier texture, simmer a few extra minutes until the soup reaches a near-puree consistency.
- Infuse Lemon Flavor: Zest one lemon using a microplane or fine grater. After the lentils are tender, squeeze the juice from the lemon into the soup and stir in the zest. The citrus adds brightness and balances the richness of the lentils, giving the soup a fresh, lively flavor.
- Taste and Adjust Seasoning: Sample the soup and adjust salt or pepper as needed. Depending on your broth’s saltiness, you may want to add more. If you prefer a more pronounced citrus note, add additional lemon juice. This step ensures each bowl is perfectly seasoned.
- Serve and Garnish: Ladle the soup into bowls and drizzle a small amount of olive oil on top. Sprinkle with paprika for color and extra flavor. Optionally, serve with crusty bread, a side salad, or fresh herbs for a complete, satisfying meal.
- Instant Pot Method Alternative: Place all ingredients except the lemon juice and zest into the Instant Pot. Lock the lid and set the vent to sealing. Select Manual or Pressure Cook mode and set the timer for 4 minutes. Allow the pot to naturally reach pressure, which may take 15–20 minutes depending on the broth temperature. When the cooking time is complete, perform a quick release for approximately 5 minutes. Stir in the lemon juice and zest, adjust seasoning, and serve as described above.
Notes
- Adjust lemon juice to taste depending on your preference for tanginess.
- Salt levels may vary depending on the sodium content of your vegetable broth—taste before adding extra.
- Red lentils cook quickly and break down easily; simmering a little longer creates a creamier texture.
- For a spicier kick, add a pinch of cayenne or chili powder.
- Optional garnishes include fresh herbs like parsley or cilantro for added freshness.
Chef’s Secrets for Perfect Soup
To elevate this simple Lemon Lentil Soup, focus on building layers of flavor.
Sauté the garlic slowly in olive oil to extract its maximum aroma without burning.
Toasting the lentils lightly before adding liquid enhances their nutty depth.
Always add lemon juice and zest at the very end to preserve their bright, fresh flavor.
If you prefer a smoother texture, use an immersion blender to lightly puree the soup.
Finally, finishing with a drizzle of quality olive oil and a sprinkle of paprika adds a professional touch that makes every serving feel gourmet.
Serving Suggestions for Everyday Enjoyment
This soup shines as a versatile meal option. Serve it with warm crusty bread or garlic naan for a comforting lunch.
For a lighter option, pair it with a fresh green salad, a sprinkle of seeds, or roasted vegetables.
It also works beautifully as part of a meal prep plan—portion into containers for grab-and-go lunches or quick weeknight dinners.
Topping with fresh herbs or a dollop of dairy-free yogurt can add a creamy contrast to the zesty soup.
Storage Tips for Best Results
Lemon Lentil Soup stores well, making it a great choice for meal prep.
Allow the soup to cool to room temperature before transferring it to airtight containers.
Refrigerate for up to 4–5 days, stirring before reheating to maintain consistent texture.
For longer storage, freeze in individual portions for up to 3 months.
When reheating, add a splash of water or broth to restore the soup’s original consistency, and always adjust seasoning to refresh the flavor after freezing.
Frequently Asked Questions
1. Can I use other lentils instead of red?
Yes, but note that green or brown lentils take longer to cook and will retain more texture. Adjust cooking time accordingly and check doneness before adding lemon juice.
2. Is this soup suitable for a low-sodium diet?
Absolutely. Use a low-sodium vegetable broth and adjust the added salt to taste. Fresh lemon juice naturally enhances flavor without adding sodium.
3. Can I make this soup creamier without dairy?
Yes! Simmer longer for a naturally creamy texture, or use an immersion blender to puree part of the soup.
Coconut milk or cashew cream can also add richness while keeping it vegan.
4. How can I make this soup spicier?
Add a pinch of cayenne, crushed red pepper, or a small diced chili while sautéing the garlic.
Adjust gradually to avoid overpowering the bright lemon flavor.
5. Can I prepare this soup in advance for meal prep?
Definitely. The soup keeps well in the refrigerator for 4–5 days or can be frozen in portions for up to 3 months.
Always reheat gently and add a splash of broth to restore consistency if needed.
