The Best Vegetarian Lentil and Sweet Potato Soup Recipe
This comforting soup combines earthy lentils, tender sweet potatoes, and warm spices like cumin and smoked paprika for a balanced, slightly smoky flavor. It’s thick, hearty, and naturally satisfying, with the option to blend part of the soup for a creamier texture.
Ingredients
- 1 cup lentils, rinsed and drained
- 2 medium sweet potatoes, peeled and diced
- 1 medium onion, chopped
- 2 cloves garlic, minced
- 4 cups vegetable broth
- 1 teaspoon ground cumin
- 1 teaspoon smoked paprika
- 1 teaspoon salt, adjust to taste
- 1/2 teaspoon black pepper
- 2 tablespoons olive oil
- Fresh parsley for garnish, optional
Instructions
Sauté the Aromatics
In a large pot, heat the olive oil over medium heat. Add the chopped onion and sauté for 3–5 minutes, until softened and translucent. Stir in the garlic and cook for another 30–60 seconds, just until fragrant.
Add the Main Ingredients
Add the diced sweet potatoes, lentils, vegetable broth, cumin, smoked paprika, salt, and pepper. Stir well to combine.
Simmer
Bring the soup to a gentle boil, then reduce the heat to low. Cover and let it simmer for 25–30 minutes, or until the lentils and sweet potatoes are tender.
Blend (Optional)
For a creamier consistency, use an immersion blender to partially blend the soup, leaving some chunks for texture. You can also transfer a portion to a blender and return it to the pot.
Taste and Serve
Taste and adjust seasoning as needed. Serve hot, garnished with fresh parsley if desired.
