Preparation	10 minutes
Cooking	25 minutes
Total Time	35 minutes

At just 35 minutes, this soup cooks about 30% faster than traditional bean-based soups, which often require soaking and longer simmering.

Step-by-Step Instructions

Step 1: Sauté the Aromatics

Heat olive oil in a large pot over medium heat.

Add:

Chopped onion
Garlic
Carrot
Celery

Cook for 4–5 minutes until the vegetables soften and release their aroma.

Pro Tip:
Slow sautéing develops deeper flavor and creates the base for a rich soup.

Step 2: Add the Smoky Spices

Stir in:

Smoked paprika
Cumin
Turmeric

Cook for 30 seconds to bloom the spices.

This step enhances the smoky depth and warmth of the soup.

Step 3: Add Lentils and Tomatoes

Add the red lentils and diced tomatoes to the pot.

Stir well to combine with the aromatic vegetables.

Step 4: Pour in the Broth

Add vegetable broth and bring the mixture to a gentle boil.

Once boiling, reduce heat and simmer for 20 minutes.

Red lentils cook quickly and naturally break down, creating a thick, creamy texture without cream.

Step 5: Add Spinach

Stir in the fresh spinach during the final 3–4 minutes of cooking.

The spinach will wilt quickly while preserving its vibrant green color and nutrients.

Step 6: Finish with Lemon Juice

Add lemon juice, salt, and black pepper to taste.

The lemon juice enhances the flavors and balances the smoky richness.
