How to Make Red Lentil Soup

Follow these simple steps to create your flavorful red lentil soup:
- In a large pot or Dutch oven, heat 3 tablespoons of olive oil over medium heat. Add the chopped onion, diced carrot, chopped celery, ½ teaspoon of sea salt, and freshly ground black pepper. Cook for about 8 minutes, stirring occasionally, until the vegetables soften.
- Stir in the diced Yukon Gold potato, chopped garlic, ground cumin, and a pinch of cayenne pepper. Cook for an additional minute to release the flavors.
- Add the rinsed red lentils, 4 cups of vegetable broth, and 1 cup of water. Bring to a gentle simmer and cook for about 30 minutes or until the lentils and potatoes are tender.
- Remove from heat and blend the soup until mostly smooth using an immersion blender. If you prefer a chunkier texture, you can blend only half of the soup.
- Stir in 2 tablespoons of fresh lemon juice and adjust the seasoning with more salt and pepper to taste. Serve hot, garnished with a drizzle of olive oil and chopped fresh parsley.
Pro Tips for Perfect Red Lentil Soup

- Add Protein: For a heartier meal, stir in some cooked chicken or chickpeas.
