  • Total Time: 35 minutes
  • Yield: 4 servings

Ingredients

Vegetables & Aromatics

  • 1 tablespoon olive oil
  • 1 medium white onion, peeled and diced
  • 2 medium carrots, diced
  • 5 cloves garlic, peeled and minced

Soup Base

  • 6 cups vegetable stock (or chicken stock)
  • 1 1/2 cups red lentils, rinsed and picked over
  • 2/3 cup whole-kernel corn

Spices & Seasonings

  • 2 teaspoons ground cumin
  • 1 teaspoon curry powder
  • Pinch of saffron (optional)
  • Pinch of cayenne pepper (optional)
  • Zest and juice of 1 small lemon
  • Fine sea salt, to taste
  • Freshly-cracked black pepper, to taste

Instructions

  1. Sauté the veggies: Heat olive oil in a large stockpot over medium-high heat. Add diced onion and carrots, sautéing for about 5 minutes until onions are soft and translucent. Add minced garlic and sauté an additional minute until fragrant.
  2. Simmer the soup: Stir in the vegetable stock, red lentils, corn, cumin, curry powder, and optional saffron and cayenne. Bring the mixture to a simmer, then cover and cook for 15 minutes, stirring occasionally, until lentils are tender.
  3. Blend the soup (optional): Use a hand blender or transfer the soup to a traditional blender to puree to your preferred consistency. Be cautious with hot liquids when using a blender.
  4. Season: Stir in the lemon zest and juice thoroughly. Taste the soup and adjust seasoning with fine sea salt and freshly cracked black pepper as needed.
  5. Serve warm: Ladle soup into bowls and garnish with an extra slice of fresh lemon if desired. Enjoy immediately.

Notes

  • For Instant Pot preparation, use the 'Sauté' function to cook aromatics first, then pressure cook for 8 minutes followed by a quick release.
  • For slow cooker, combine all ingredients (except oil) and cook on high for 2-3 hours or low for 5-6 hours until lentils are tender.
  • Blending the soup is optional; it can be served chunky or smooth according to preference.
  • When blending hot soup in a traditional blender, blend in batches and vent the lid slightly to prevent pressure buildup.
  • This soup freezes well; store in airtight containers for up to 3 months.
  • Adjust spices to taste; the optional saffron and cayenne can be omitted or increased depending on your flavor preference.
