Step-by-Step Cooking Directions

1. Soak the Lentils: Place the rinsed red lentils in a bowl, cover with water by 2 inches, and let soak for 10 minutes. Drain and set aside.

The Origins and Popularity of the Recipe

Lentil soups have nourished civilizations for millennia, with early records in Ancient Egypt and the Mediterranean. In Middle Eastern cuisine, red lentil soups—known as “shorbat adas”—are a staple during Ramadan and throughout the year, prized for their quick cooking time and creamy texture. South Asian dals utilize similar legumes, often tempered with aromatic spices. This red lentil and spinach version blends those time-honored traditions with modern produce like bell peppers and spinach, reflecting global kitchen cross-pollination. Its popularity has surged with the rise of plant-based eating and global fusion cuisine, appearing on menus from casual cafes to fine-dining establishments as a testament to lentils’ versatility and health benefits.

Ingredient Spotlight: Red Lentils

Red lentils are split and hulled, allowing rapid absorption of water and quick breakdown during cooking. Unlike whole lentils, they yield a naturally creamy texture without blending. Their mild, slightly sweet flavor makes them ideal carriers for bold spices and aromatics. Nutritionally, red lentils boast high protein, fiber, iron, and folate, making them an exceptional choice for plant-based and general healthy eating.

Frequently Asked Questions

1. Can I substitute another type of lentil?
Green or brown lentils work but require longer cooking (25–30 minutes) and yield a firmer texture.

5. How can I make the soup thicker?
Blend 1–2 cups of the soup with an immersion blender or regular blender and return to the pot.

6. What if I don’t have fresh spinach?
Use frozen spinach (75 g), thawed and drained, adding it at the same stage as fresh greens.

7. Can I omit turmeric?
Yes; you can substitute ground cumin or curry powder for a different flavor profile.

8. How do I prevent lentils from sticking?
Stir occasionally during simmering and maintain a low, steady heat.
