Ingredients

  • 2 tablespoons olive oil
  • 1 medium yellow onion, diced
  • 2 medium carrots, peeled and diced
  • 2 celery stalks, diced
  • 3 garlic cloves, minced
  • 1 teaspoon ground cumin
  • 1/2 teaspoon smoked paprika
  • 1 cup dried brown lentils, rinsed
  • 1 medium sweet potato, peeled and diced
  • 1 can (14.5 oz) diced tomatoes
  • 6 cups vegetable broth
  • 1 bay leaf
  • Salt and pepper to taste
  • 2 cups fresh baby spinach

Instructions

  1. Heat olive oil in a large pot over medium heat. Add diced onion, carrots, and celery. Sauté for 6-8 minutes until vegetables are soft and onions are translucent.
  2. Stir in minced garlic, ground cumin, and smoked paprika. Cook for 1 minute until fragrant.
  3. Add rinsed lentils, diced sweet potato, canned diced tomatoes (with juices), vegetable broth, and bay leaf. Stir to combine.
  4. Bring the soup to a boil, then reduce heat to low and cover. Let it simmer gently for 35-40 minutes until lentils and sweet potatoes are tender.
  5. Remove bay leaf. Use an immersion blender to partially puree the soup for a creamy texture while leaving some lentils and veggies whole, or skip this step for a chunkier soup.
  6. Stir in fresh spinach and cook for 2-3 minutes until wilted.
  7. Season with salt and pepper to taste. If soup is too thick, add a bit more broth or water to reach desired consistency.
  8. Ladle soup into bowls and serve warm. Optionally, garnish with fresh parsley or a dollop of Greek yogurt.

Chef tips

  • If you don’t have smoked paprika, substitute with regular paprika or a pinch of chili powder for mild heat.
  • To make it vegan, avoid topping with Greek yogurt and use vegetable broth labeled vegan.
  • You can swap sweet potato for butternut squash or pumpkin cubes depending on what’s available.
  • This soup thickens upon standing. Add extra broth or water when reheating to loosen the texture.

Pros

  • Packed with fiber and protein from lentils and vegetables.
  • Fragrant and flavorful with gentle spices suitable for kids.
  • Simple ingredients and straightforward preparation makes it great for busy home cooks.

Cons / watch-outs

  • Cook time is moderate due to lentils needing time to soften.
  • Not gluten-free if using store-bought broth with gluten additives; check labels if needed.
