Ingredients

For this vibrant Vegan Lemon Lentil Soup with Turmeric, you’ll need:

• 1½ cups (300g) red lentils, rinsed and drained
• 2 tablespoons olive oil
• 1 large yellow onion, finely diced (about 1½ cups)
• 3 medium carrots, diced (about 1 cup)
• 3 celery stalks, diced (about ¾ cup)
• 4 garlic cloves, minced
• 1 tablespoon fresh ginger, grated
• 2 teaspoons ground turmeric
• 1 teaspoon ground cumin
• ½ teaspoon ground coriander
• ¼ teaspoon cayenne pepper (optional, adjust to taste)
• 6 cups (1.4 liters) vegetable broth
• 1 bay leaf
• Juice of 2 medium lemons (about ¼ cup)
• Zest of 1 lemon
• 1 teaspoon salt (or to taste)
• ½ teaspoon freshly ground black pepper
• ¼ cup fresh cilantro or parsley, chopped for garnish

Red lentils are ideal for this soup as they cook quickly and break down to create a naturally thickened broth. The turmeric not only provides anti-inflammatory benefits but also gives the soup its signature golden color.

Pro Tips

Sauté the Aromatics Properly: The foundation of a flavorful Vegan Lemon Lentil Soup with Turmeric starts with properly sautéing your aromatics. Take the time to cook your onions until translucent (about 4-5 minutes) before adding the carrots and celery. This layering of ingredients builds a more complex flavor profile. Don’t rush this step – those golden, slightly caramelized edges on the vegetables contribute significant depth to the final soup.

Bloom Your Spices: Always add the turmeric, cumin, and other dry spices to the oil with the vegetables and cook them for 30-60 seconds before adding liquid. This technique, called “blooming,” releases the fat-soluble flavor compounds in the spices, intensifying their impact in the final dish. You’ll know they’re ready when they become noticeably fragrant – just be careful not to burn them.

Add Lemon at the Right Time: For the brightest flavor in your lemon turmeric soup, add most of the lemon juice toward the end of cooking. Heat dampens citrus brightness, so stirring in the lemon juice about 5 minutes before serving preserves its vibrant flavor. For an extra dimension, reserve a small amount of fresh lemon juice to add to individual bowls just before serving – this final touch elevates the entire soup with a fresh burst of acidity.

Instructions

Step 1

Heat olive oil in a large Dutch oven or heavy-bottomed pot over medium heat. Add the diced onion and cook for 4-5 minutes until translucent and beginning to soften. Stir occasionally to prevent browning.

Step 2

Add the carrots and celery to the pot, cooking for another 3-4 minutes until they begin to soften. Stir in the minced garlic and grated ginger, cooking for just 30 seconds until fragrant – you’ll notice that wonderful aroma rising from the pot!

Step 3

Now it’s time for the spice magic! Add the turmeric, cumin, coriander, and cayenne (if using). Stir continuously for 30-60 seconds to toast the spices in the oil. This crucial step releases their essential oils and creates a more intense flavor for your Vegan Lemon Lentil Soup with Turmeric.

Step 4

Add the rinsed red lentils to the pot and stir to coat them with the spiced oil mixture. This quick coating helps the lentils absorb all those wonderful flavors you’ve been developing.

Step 5

Pour in the vegetable broth and add the bay leaf. Bring the mixture to a boil, then reduce heat to maintain a gentle simmer. Cover partially and cook for 20-25 minutes, or until the lentils have softened and begun to break down. Stir occasionally to prevent sticking.

Step 6

Once the lentils are tender, remove the bay leaf. For a creamier texture, use an immersion blender to partially blend the soup, leaving some texture intact. If you prefer a chunkier soup, you can skip this step or just blend a small portion.

Step 7

Stir in the lemon juice, lemon zest, salt, and pepper. Simmer for an additional 5 minutes to allow the flavors to meld. Taste and adjust seasonings as needed – you might want more lemon juice for brightness or a pinch more salt to enhance the flavors.

Step 8

Ladle your beautiful golden Vegan Lemon Lentil Soup with Turmeric into bowls and garnish generously with fresh chopped cilantro or parsley. For an extra touch of brightness, add a small lemon wedge to each serving.

Variations

Mediterranean Style: Transform your Vegan Lemon Lentil Soup with Turmeric into a Mediterranean delight by adding 1 cup of diced tomatoes and 2 cups of chopped fresh spinach during the last 5 minutes of cooking. Finish with a sprinkle of oregano and a few kalamata olives on top. This variation adds vibrant color contrast and nutritional benefits while maintaining the soup’s zesty character.

Coconut Curry Version: For a creamier, more indulgent twist on this lemon turmeric soup, replace 2 cups of the vegetable broth with 1 can (14 oz) of full-fat coconut milk. Add 1 tablespoon of curry powder along with the other spices and a tablespoon of maple syrup to balance the flavors. This variation creates a luxurious texture with tropical notes that complement the turmeric and lemon beautifully.

Hearty Vegetable Boost: Make this soup even more substantial by adding 1 cup of diced sweet potato or butternut squash with the carrots and celery, and stirring in 1 cup of frozen peas during the last 3 minutes of cooking. This creates a complete one-pot meal with additional texture and nutritional variety while still showcasing the bright lemon and turmeric flavors.

Storage and Serving

This Vegan Lemon Lentil Soup with Turmeric stores beautifully, making it perfect for meal prep. Refrigerate in airtight containers for up to 5 days – the flavors will continue to develop, making it even more delicious on day two. For longer storage, freeze portions in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator and reheat gently on the stovetop, adding a splash of vegetable broth if needed to adjust consistency.

Serve this golden soup with a thick slice of crusty sourdough bread for dipping – the tangy bread perfectly complements the lemon notes in the soup. For a more substantial meal, pair it with a simple side salad dressed with olive oil and lemon juice to echo the soup’s bright flavors.

For an elegant presentation, serve in shallow bowls with a swirl of plant-based yogurt or coconut cream on top, a sprinkle of lemon zest, and a few pumpkin seeds for crunch. This creates a beautiful color contrast against the vibrant yellow soup and adds textural interest to each spoonful.

FAQs

Can I use green or brown lentils instead of red?
Yes, you can substitute other lentil varieties, but note that green or brown lentils hold their shape more and won’t break down as much as red lentils. They also require longer cooking (30-35 minutes). This will result in a chunkier soup with a different texture, but the flavors will still be delicious.

How can I make this soup less thick?
If your Vegan Lemon Lentil Soup with Turmeric is thicker than you prefer, simply add more vegetable broth until you reach your desired consistency. Add 1/4 cup at a time, stirring well between additions.

Is this soup spicy?
The cayenne pepper adds a mild heat, but it’s optional. For a completely non-spicy version, omit the cayenne. For more heat, increase the cayenne or add a diced jalapeño with the other vegetables.

Can I make this in an Instant Pot?
Absolutely! Use the sauté function for the first few steps, then pressure cook on high for 10 minutes with a natural release of 5 minutes before manually releasing remaining pressure.

Will the turmeric stain my containers?
Turmeric can temporarily stain plastic containers. To prevent this, spray the container with cooking spray before adding the soup, or use glass containers instead.
