Lentil Soup with Nigella Tarka
A comforting, high-fiber red lentil soup completely transformed by a final sizzle of aromatic nigella seeds bloomed in hot oil, offering a burst of flavor and aroma in every spoonful.
For 4 servings
Rinse the red lentils thoroughly under cold running water until the water runs clear. Set aside to drain.
In a large pot or Dutch oven, heat 1 tablespoon of ghee or oil over medium heat. Add the chopped onion and sauté for 5-7 minutes until softened and translucent.
Add the minced garlic and grated ginger to the pot. Cook for another 1-2 minutes until fragrant, being careful not to burn the garlic.
Stir in the diced tomatoes, turmeric powder, and cumin powder. Cook for 2-3 minutes, stirring occasionally, until the tomatoes soften slightly and the spices are fragrant.
Add the rinsed lentils and vegetable broth to the pot. Bring the mixture to a boil, then reduce the heat to low, cover, and simmer for 15-20 minutes, or until the lentils are tender and have broken down, creating a creamy consistency.
Season the soup with salt and black pepper to taste. If the soup is too thick, add a little more hot water or broth to reach your desired consistency. Stir well.
While the soup is simmering, prepare the tarka (tempering). In a small pan, heat the remaining 1 tablespoon of ghee or oil over medium heat until shimmering.
Add the nigella seeds to the hot ghee/oil. Cook for about 30 seconds, or until the seeds begin to sizzle and release their aroma. Be careful not to burn them, as they can become bitter.
Immediately pour the hot, sizzling nigella seed tarka over the cooked lentil soup. Stir gently to incorporate the flavors.
Ladle the soup into bowls. Garnish with fresh chopped cilantro and serve hot with lemon wedges on the side, if desired.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1Rinsing lentils: Always rinse your lentils thoroughly to remove any debris and excess starch, which can make the soup cloudy.
- 2Adjusting consistency: Red lentils break down significantly, making the soup naturally thick. If you prefer a thinner soup, add more hot vegetable broth or water until you reach your desired consistency.
- 3Tarka timing: The tarka should be prepared just before serving to maximize its aromatic impact. Pour it over the soup immediately after the seeds sizzle to capture their fresh, bloomed flavor.
- 4Don't overcook the tarka: Nigella seeds can turn bitter if cooked for too long or at too high a heat. Watch them carefully and remove from heat as soon as they become fragrant.
