Step-by-Step Instructions

1. Build the base.
Heat olive oil in a large pot over medium heat. Add onion and cook until soft and fragrant.

2. Add garlic and ginger.
Stir in minced garlic and grated ginger. Cook for about 30 seconds.

3. Add lentils and spices.
Toss in red lentils, cumin, smoked paprika, salt, and pepper. Stir to coat everything evenly.

4. Pour in liquids.
Add crushed tomatoes and vegetable broth. Bring to a gentle boil.

5. Simmer patiently.
Reduce heat and let it simmer for 20–25 minutes. Lentils will soften and thicken the soup.

Stir in maple syrup and lemon juice. Taste and adjust sweetness or sourness.

7. Finish with greens.
Add spinach or kale and let it wilt. Serve hot with fresh herbs on top.
