Ingredients

Soup Base

  • 2 tablespoons olive oil
  • 1 medium onion, finely chopped
  • 2 cloves garlic, minced
  • 1 medium carrot, diced
  • 1 teaspoon ground cumin
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon turmeric (optional)

Lentils and Broth

  • 1 cup red lentils, rinsed
  • 4 cups vegetable broth
  • 1 cup water
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper

Greens

  • 2 cups fresh spinach, roughly chopped

Finishing Touch

  • 1 tablespoon lemon juice
  • Extra olive oil for drizzling
  • Fresh parsley or cilantro for garnish

Instructions

Step 1 – Sauté the Aromatics

Heat olive oil in a large pot over medium heat.

Add the chopped onion and cook for 4–5 minutes until softened and slightly translucent.

Stir in the minced garlic and diced carrot, cooking for another 2 minutes until fragrant.

Step 2 – Add the Spices

Sprinkle in the cumin, smoked paprika, and turmeric.

Cook for about 30 seconds, stirring constantly. This step helps toast the spices and release their aromas, which gives the soup its deep smoky flavor.

Step 3 – Add Lentils and Broth

Stir in the rinsed red lentils.

Pour in the vegetable broth and water, then add salt and black pepper.

Bring the mixture to a gentle boil.

Step 4 – Simmer the Soup

Reduce the heat to low and let the soup simmer for 20–25 minutes, stirring occasionally.

The lentils will soften and begin to break down, creating a naturally creamy texture.

Step 5 – Add the Spinach

Once the lentils are tender, stir in the chopped spinach.

Cook for 2–3 minutes until the spinach wilts into the soup.

Step 6 – Finish with Lemon

Stir in fresh lemon juice to brighten the flavors.

Taste and adjust seasoning if necessary.

Step 7 – Serve and Garnish

Ladle the soup into bowls and drizzle with olive oil.

Garnish with fresh parsley or cilantro and a sprinkle of smoked paprika for extra color.

Serve warm.


Why Red Lentils Are Perfect for Soup

Red lentils are one of the best legumes for soups because they cook quickly and break down easily. Unlike brown or green lentils, red lentils become soft and creamy as they simmer, naturally thickening the soup without needing cream or flour.

This makes them ideal for creating rich and hearty soups while keeping the recipe healthy and plant-based.

Red lentils also absorb flavors beautifully, allowing spices like cumin and smoked paprika to shine.


The Power of Smoky Flavor

Smoked paprika is the ingredient that gives this soup its signature taste.

Unlike regular paprika, smoked paprika is made from peppers that are dried over wood smoke. This process creates a deep, slightly smoky flavor that adds complexity to simple dishes.

Just a small amount can transform an ordinary lentil soup into something truly special.


Tips for the Best Lentil Soup

Rinse the Lentils

Rinsing removes dust and excess starch.

Stir Occasionally

Lentils can stick to the bottom of the pot if left unstirred.

Adjust Thickness

Add extra broth or water if you prefer a thinner soup.

Blend for Creaminess

For an ultra-smooth texture, blend part of the soup with an immersion blender.

You can also enjoy it as a light lunch or serve it as a starter before a main meal.
