Why Red Lentil Soup is Good for You

Red lentils, the main ingredient in this recipe, are a nutritional powerhouse. They’re rich in plant-based protein, making them ideal for those who eat a plant-based diet or anyone aiming to eat healthier. Their high fiber makes them great for weight management since fiber keeps you feeling full longer and supports digestion. What’s more? Red lentils are loaded with essential nutrients like iron, folate, and potassium, which boost energy and promote heart health.

Pairing red lentils with lemon enhances the flavor and adds a burst of vitamin C, improving the absorption of iron from the lentils. This makes red lentil soup both delicious and nutritionally balanced.

Ingredients You’ll Need

  • 1 sweet onion, diced: Adds subtle sweetness and a flavor base.
  • 4 cloves fresh garlic, minced: Provides aromatic depth to complement the lentils.
  • 2 tbsp avocado or extra virgin olive oil: Used for sautéing, adding richness.
  • 1/2 tsp smoked paprika: Gives the soup a smoky undertone.
  • 1/2 tsp cumin powder: Adds warmth and earthiness.
  • 3/4 tsp salt: Enhances overall flavor.
  • 1 cup dried red lentils: Quick-cooking and perfect for a creamy texture.
  • 4 cups vegetable broth: A flavorful base to tie everything together.
  • 1 lemon, juiced: Brightens the soup with a refreshing zing.
  • Optional: Lemon zest for garnish and added citrus aroma.

How to Make Red Lentil Soup

1. Prepare the Vegetables

Start by dicing the sweet onion and mincing the garlic. These steps ensure even cooking and allow the flavors to meld beautifully.

2. Sauté Aromatics

Heat 2 tablespoons of oil in a stock pot over medium-high heat. Add the onion and garlic, sautéing until the onion is translucent and slightly golden. This step caramelizes the onion for a deeper flavor.

3. Add Spices

Stir in the smoked paprika and cumin. Let the spices cook for about a minute to release their aroma and intensify the flavor.

4. Combine Ingredients

Pour in the vegetable broth, followed by the red lentils. Add the lemon juice and, if desired, some lemon zest. Stir everything together to ensure the flavors are evenly distributed.

5. Simmer the Soup

Bring the soup to a gentle boil, then reduce the heat to low. Allow it to simmer for about 20 minutes, stirring occasionally. The lentils will soften and thicken the soup, creating a creamy, hearty texture.

6. Serve and Enjoy

Ladle the soup into bowls, garnish with lemon zest or fresh parsley, and serve warm. Pair with crusty bread for a complete and satisfying meal.

Tips for the Best Red Lentil Soup

  • Adjusting Consistency: If you prefer a thicker soup, let it simmer longer or blend a portion of it with an immersion blender.
  • Boosting Flavor: A pinch of cayenne pepper can add a slight kick, while fresh herbs like cilantro bring brightness.
  • Storage: Store leftovers in an airtight container in the fridge for up to 5 days, or freeze for up to 3 months. Reheat gently before serving.
