How to Make Smoky Red Lentil Soup with Spinach

Step 1: Cook the Vegetables

Heat the olive oil in a large soup pot over medium heat.

Add the chopped onion, carrots, and celery. Cook for about 6 to 8 minutes until the vegetables begin to soften.

Stir in the garlic and cook for another 30 seconds.

Step 2: Add the Seasonings

Mix in the tomato paste, smoked paprika, cumin, coriander, salt, black pepper, and cayenne pepper if using.

Cook for 1 minute while stirring to release the flavors of the spices.

Step 3: Add the Lentils

Pour in the rinsed red lentils, diced tomatoes, and vegetable broth.

Stir everything together well.

Step 4: Simmer

Bring the soup to a gentle boil.

Reduce the heat to low, cover the pot, and simmer for about 20 to 25 minutes until the lentils are very soft.

Step 5: Blend (Optional)

For a smoother soup, blend part or all of the soup using an immersion blender.

If you enjoy a chunkier texture, skip this step.

Step 6: Add the Spinach

Stir in the fresh spinach and cook for about 2 to 3 minutes until wilted.

Step 7: Finish the Soup

Add the lemon juice and stir well.

Taste and adjust the seasoning if needed.

Step 8: Serve

Ladle the soup into bowls.

Garnish with fresh parsley and serve warm.

Common Mistakes to Avoid

Not Rinsing the Lentils

Always rinse lentils to remove dust and any small debris.

Cooking the Spinach Too Long

Add the spinach at the end so it stays fresh and vibrant.

Using Too Much Heat

A gentle simmer helps the lentils cook evenly without sticking.

Skipping the Lemon Juice

The lemon balances the smoky flavors and brightens the soup.

Over-Blending

If you prefer texture, blend only part of the soup instead of making it completely smooth.
