Ingredients
• 1½ cups (300g / 10.6 oz) red lentils, rinsed
• 4 cups (950ml) water, plus more if needed
• 1 tablespoon (15ml / 0.5 fl oz) vegetable oil
• ½ teaspoon (3g / 0.11 oz) salt
• 2 medium potatoes (about 1 lb / 450g), peeled and cut into ½-inch dice
• 4 tablespoons (57g / 2.01 oz) butter
• 1 medium onion, diced
• 2 cloves garlic, minced
• 1 teaspoon (5 ml / 0.2 fl oz) turmeric
• 1½ teaspoons ground cumin
• 1½ teaspoons ground coriander
• ⅛ teaspoon cayenne pepper
• Additional butter, for serving
Instructions
1. Cook the Lentils: In a medium saucepan, combine the rinsed red lentils, water, oil, and salt. Bring to a boil over medium-high heat, then reduce the heat to a simmer. Cook, uncovered, for 20 minutes, stirring occasionally. Skim off any foam that rises to the surface.
2. Add Potatoes: Stir the diced potatoes into the lentil mixture and continue to simmer.
3. Sauté the Aromatics: While the soup simmers, melt the butter in a small skillet over medium heat. Add the diced onion, minced garlic, turmeric, cumin, coriander, and cayenne pepper. Sauté for 3-4 minutes, until the onion is soft and the spices are fragrant.
4. Combine and Simmer: Carefully pour the spiced onion mixture into the soup pot. Stir well to combine. Continue to cook for another 20 minutes, or until the potatoes are fork-tender. If the soup becomes too thick, add a splash of water to reach your desired consistency.
5. Serve: Taste the soup and adjust the seasoning with more salt if needed. Ladle into bowls and top each serving with a small pat of butter.

Pro Tips
• Make it Ahead: This soup tastes even better the next day! Prepare it at least an hour ahead of time, or even the day before, and gently reheat before serving to allow the flavors to meld.
• Add a Bright Finish: A squeeze of fresh lemon juice or a dollop of plain yogurt just before serving can cut through the richness and brighten up all the flavors.
• Make it Vegan: Easily make this soup vegan by swapping the butter for a plant-based butter or an equal amount of coconut oil.
• Blend for Creaminess: For a smoother, creamier texture, use an immersion blender to partially or fully blend the soup after the potatoes are cooked.
FAQ
Q: How can I make this lentil potato soup vegan
A: To make this soup vegan, simply substitute the dairy butter with a plant-based butter or an equal amount of coconut or olive oil. The rest of the ingredients are naturally plant-based, making this an easy and delicious vegan meal.
Q: Is this vegetarian soup a good source of protein
A: Yes, it’s an excellent source of plant-based protein. Red lentils are protein powerhouses, and a single serving of this soup contains approximately 20 grams (0.71 oz / 20.1 g) of protein, making it a very filling and nutritious vegetarian option.
Q: Can I make this red lentil soup ahead of time
A: Absolutely! This soup is perfect for meal prep as the flavors meld and deepen overnight. Store it in an airtight container in the refrigerator for up to 4-5 days. The soup will thicken as it cools, so you may need to add a splash of water or vegetable broth when reheating.
Q: What other vegetables can I add to this soup
A: This recipe is very versatile. Feel free to add other vegetables like carrots, celery, or spinach. Add diced carrots and celery with the onions to soften them. Stir in spinach at the very end of cooking until it just wilts.
