Ingredients Needed

Here’s what you’ll need to get started. While you might already have some of these ingredients in your kitchen, others are just as easy to grab from the grocery store.

Lentils – 1 ½ cups (green or brown lentils work best)
Vegetable broth – 6 cups (for a heartier, richer flavor, opt for a low-sodium option)
Carrots – 2 medium, diced
Celery – 2 stalks, diced
Onion – 1 large, diced (yellow onion is a classic, but white onion can also work)
Garlic – 3 cloves, minced (garlic powder can be used if you don’t have fresh)
Tomatoes – 1 can (14.5 oz) of diced tomatoes or 2 fresh tomatoes, diced
Spinach – 2 cups (optional, but adds a nice boost of greens)
Olive oil – 2 tablespoons (for sautéing)
Bay leaves – 2 (they add a subtle aromatic flavor)
Cumin – 1 teaspoon (warm and earthy)
Turmeric – ½ teaspoon (for that golden color and subtle depth)
Salt and pepper – to taste
Lemon juice – 2 tablespoons (adds a touch of brightness to balance the flavors)

Cooking Instructions

Making lentil soup is as simple as combining the right ingredients, letting them simmer, and allowing all the flavors to meld together. Here’s how to do it step-by-step:

Prep Your Vegetables: Start by chopping your carrots, celery, onion, and garlic. Having everything prepped ahead of time will make the cooking process smooth and easy.
Sauté the Vegetables: Heat the olive oil in a large pot over medium heat. Once hot, add the onions and sauté for about 3 minutes, until they become translucent. Then, add the garlic, carrots, and celery. Continue to sauté for an additional 5 minutes, stirring occasionally.
Add Spices: Sprinkle in the cumin, turmeric, salt, and pepper. Stir well to coat the vegetables in the spices, and cook for another 2 minutes to let the spices release their aromas.
Add Lentils and Tomatoes: Pour in the lentils and diced tomatoes (with their juices), and stir everything together. Add the vegetable broth and bay leaves. Bring the soup to a boil.
Simmer the Soup: Once the soup is boiling, reduce the heat to low, cover, and let it simmer for about 30-40 minutes. The lentils should be tender, and the soup should have thickened up. Stir occasionally.
Add Greens: If you’re adding spinach (or any other greens), stir it into the soup when the lentils are just about done. Let the spinach wilt into the soup for about 5 minutes.
Finish with Lemon: Once the soup is ready, remove the pot from the heat and stir in the lemon juice to add a touch of brightness. Taste and adjust the seasoning if needed, adding more salt, pepper, or a pinch of cumin if you like.
Serve and Enjoy: Ladle the soup into bowls, and enjoy! You can serve it with a slice of crusty bread or a dollop of yogurt for extra creaminess.

Ingredient Insights

Lentil soup is not just delicious; it’s also packed with nutrients. Here’s why each of these ingredients contributes to the overall goodness of the soup:

Lentils: They’re the main source of protein in this dish. Lentils are also rich in fiber, which helps with digestion and keeps you full longer. Plus, they contain essential nutrients like iron, folate, and magnesium.
Vegetable Broth: Using a vegetable broth as the base adds flavor without extra calories. It’s also a great way to keep the soup vegan, while still providing a rich, savory depth of flavor.
Carrots & Celery: These vegetables provide natural sweetness and a slight crunch, making the texture of the soup more interesting. They’re also high in vitamins A and K, as well as antioxidants.
Garlic: Known for its immune-boosting properties, garlic adds a pungent, savory flavor that makes the soup even more irresistible.
Tomatoes: They add acidity, sweetness, and richness to balance the earthy lentils. They also provide vitamins A and C, plus lycopene, an antioxidant.
Spinach: If you choose to add spinach, you’ll be packing in more iron, fiber, and vitamins A and K. It also adds vibrant green color to the soup.

Expert Tips

To make this lentil soup even more flavorful, here are a few tips from culinary experts:

Use homemade vegetable broth if you can. It’s easy to make and will add a fresher, more vibrant taste compared to store-bought versions. Plus, you can control the sodium levels.
Soak your lentils: Though not strictly necessary, soaking lentils for about 30 minutes before cooking can reduce cooking time and make them even softer. It also helps improve digestibility.
Add a Parmesan rind: If you’re not strictly vegan, adding a Parmesan rind while the soup simmers gives it an extra layer of umami richness. Just remember to remove it before serving.
Layer the spices: Don’t just throw all your spices in at once. By adding them in stages-first while sautéing the vegetables and then once the broth is in-you help the flavors develop more deeply.
Control consistency: If you prefer your soup a little thicker, you can blend part of it using an immersion blender or regular blender. You can also mash some of the lentils against the side of the pot to thicken it up.

Recipe Variations

The beauty of lentil soup is in how easily you can switch things up. Here are a few variations to try:

Spicy Lentil Soup: Add some chili flakes, a pinch of cayenne pepper, or even a chopped jalapeño for a bit of heat.
Mediterranean Twist: Add in chopped olives, artichokes, or roasted red peppers. A dollop of hummus on top would complement these flavors beautifully.
Indian-inspired Lentil Soup: Swap out the cumin and turmeric for garam masala and curry powder. A splash of coconut milk can add richness and a touch of sweetness.
Meat Lovers’ Lentil Soup: Brown some ground beef, turkey, or sausage and add it to the soup for a non-vegan option.

Final Words

Making lentil soup from scratch isn’t just about feeding your body-it’s about enjoying the process of creating something that’s hearty, nutritious, and made with love. The wonderful thing about lentil soup is that it’s endlessly adaptable. You can change up the vegetables, experiment with spices, and make it as thick or brothy as you like. It’s the kind of dish that allows you to get creative and find your perfect bowl.
