Recipe Overview
Total Time: 45 minutes
Servings: Not specified (adjust ingredients for 4–6 servings)
Ingredients
Aromatics
3 tablespoons olive oil (plus extra for drizzling)
1 large onion, finely chopped
2 garlic cloves, minced
Spices & Base
1 tablespoon tomato paste
1 teaspoon ground cumin
¼ teaspoon salt (adjust to taste)
¼ teaspoon black pepper (adjust to taste)
Pinch of chili powder or ground cayenne (more to taste)
Liquid Base
- 1 quart (32 oz) chicken or vegetable broth
Lentils
- 1 cup red lentils (rinsed to remove excess starch)
Vegetables
- 1 large carrot, peeled and diced
Fresh Accents
Juice of ½ lemon (more to taste)
3 tablespoons chopped fresh cilantro
Preparation Instructions
Step 1: Sauté Aromatics
Heat olive oil in a large pot over high heat until shimmering. Add onion and garlic; sauté until onion turns translucent and garlic becomes fragrant, about 4 minutes.
Step 2: Toast Spices
Stir in tomato paste, cumin, salt, black pepper, and chili powder. Sauté for 2 minutes to toast spices and meld flavors, ensuring tomato paste coats onions evenly.
Step 3: Simmer Base
Add broth, 2 cups water, red lentils, and diced carrot. Bring to a gentle simmer (not boiling), then partially cover the pot and reduce heat to medium-low. Simmer until lentils are tender (they will break down slightly), about 30 minutes. Taste and adjust salt as needed.
Step 4: Partial Puree for Texture
Using an immersion blender (directly in the pot) or a regular blender (transferring half the soup to a container), purée half the soup in short bursts until smooth, then return to the pot. The result should be slightly chunky (avoid over-blending for rustic texture).
Step 5: Finish & Serve
Reheat gently if needed. Stir in lemon juice and fresh cilantro. Drizzle with extra olive oil and a light dusting of chili powder for depth, if desired.
Community Comments & Tips
Seasoning & Flavor Enhancements
"This is daal, minus key Indian seasonings. Enhance with ginger-garlic paste, fresh chopped tomatoes (no paste), and spices like turmeric, coriander powder, or a pinch of cinnamon (for warmth)."
"Add ½ teaspoon turmeric for color and earthiness; adjust salt to taste early (lentils absorb flavor over time)."
Substitutions & Adaptations
"For a richer, tomato-forward twist: replace ½ cup water with 14-oz can diced tomatoes + extra broth. Add 3 carrots (or 1–2 small diced potatoes) for body."
"Vegan-friendly: swap chicken broth for vegetable broth. Add a can of coconut milk (instead of water) for creaminess, plus fresh spinach at the end."
"Non-vegan: use chicken stock; stir in a handful of chopped kale or spinach for greens."
Texture & Consistency
"Avoid transferring soup: blend in short pulses directly in the pot for a slightly rough, uneven consistency."
"Too much liquid? Reduce water to 1 cup, or add 1 small diced potato (cubed) to thicken."
Kitchen Shortcuts
"Skip blending for a rustic texture; stir in spinach at the end and top with grated Parmesan or fresh coriander."
"Pair with a tangy chutney: mix plain yogurt, green chilies, and cilantro."
Chef’s Notes
For authentic daal depth, add 1 tablespoon ginger-garlic paste with garlic in Step 1.
Use red pepper flakes instead of chili powder for a milder heat, or adjust to taste.
The soup freezes well; double the batch for future meals.
