Pro Tips

• This soup tastes even better the next day! Make a double batch and store it in an airtight container in the fridge for up to 4 days for easy lunches.
• For a vegan version, simply swap the Greek yogurt for a dairy-free plain yogurt, a drizzle of tahini, or a dollop of cashew cream.
• Add ¼ teaspoon of smoked paprika along with the cumin seeds for an even deeper, smokier flavor. A squeeze of fresh lemon juice just before serving will also brighten everything up.
• For a creamier consistency, use an immersion blender to briefly pulse the soup a few times before serving, leaving some lentils whole for texture.

FAQ

Q: Is this lentil and leek soup a good source of plant-based protein
A: Absolutely. This soup is packed with 18 grams of protein per serving, primarily from the hearty brown lentils. The optional Greek yogurt topping also adds an extra protein boost, making it a very satisfying and nutritionally complete vegetarian meal.

Q: How can I make this smoky lentil soup vegan
A: To make this recipe completely vegan, simply replace the nonfat Greek yogurt garnish. Excellent dairy-free alternatives include a dollop of plain plant-based yogurt (like soy or coconut), a rich drizzle of tahini, or a spoonful of creamy cashew cream.

Q: Can I use different lentils for this recipe
A: Yes, you can substitute other lentils, but it will affect the cooking time and texture. Green or Puy lentils are a great substitute as they hold their shape well, similar to brown lentils. Red or yellow lentils cook much faster and will break down, creating a creamier, thicker soup, so you may need to reduce the cooking time slightly.

Q: How long does this vegetarian lentil soup last in the fridge
A: This soup is perfect for meal prep and tastes even better the next day. Store it in an airtight container in the refrigerator for up to 4 days. The smoked almonds should be stored separately and added just before serving to maintain their crunch.
