Ingredients

• 2 medium sweet potatoes, peeled and cubed (approximately 500 g)

• 1 medium onion, diced

• 2 garlic cloves, minced

• 1 can white beans, drained and rinsed (400 g can; approximately 240 g drained)

• 4 cups low-sodium vegetable broth (960 ml)

• ½ cup plain Greek yogurt (120 g)

• 1 tablespoon olive oil (15 ml)

• 1 teaspoon smoked paprika

• ½ teaspoon ground cumin

• ½ teaspoon dried thyme

• ½ teaspoon salt, or to taste

• ¼ teaspoon black pepper

• 1 tablespoon lemon juice

• 2 tablespoons chopped fresh parsley, optional

How to Make High-Protein Sweet Potato Soup

Step 1: Soften the aromatics. Heat the olive oil in a large saucepan over medium heat. Add the diced onion and cook for 4–5 minutes until softened. Stir in the garlic, smoked paprika, cumin and thyme.

Step 2: Add the vegetables. Tip in the cubed sweet potatoes, drained white beans and vegetable broth. Stir everything together, scraping up the flavorful ingredients from the bottom of the pan.

Step 3: Simmer until tender. Bring the mixture to a gentle boil, then reduce the heat. Cover partially and simmer for 18–22 minutes, or until the sweet potatoes are completely tender.

Step 4: Blend until creamy. Remove the pan from the heat and blend using an immersion blender until smooth. Alternatively, blend in batches in a countertop blender, following its hot-liquid safety instructions.

Step 5: Add the creamy finish. Allow the soup to cool slightly before stirring in the Greek yogurt. Add the lemon juice, black pepper and salt to taste. If the soup is too thick, add a splash of warm broth.

Step 6: Serve and enjoy. Ladle into bowls and finish with chopped parsley and a sprinkle of smoked paprika. Serve warm with whole-grain toast for a comforting, satisfying meal.

Pro Tips for the Best Sweet Potato Soup

Use evenly sized sweet potato cubes. This helps everything cook at the same rate and makes blending easier.

Build flavor before adding broth. Gently cooking the onion, garlic and spices first gives this simple soup a deeper, richer taste.

Keep the yogurt from splitting. Stir it in after removing the pan from the heat. Avoid boiling the soup once the yogurt has been added.

Make it your own. Add ginger for extra warmth, chili flakes for a little heat or baby spinach for a fresh green finish.

Prepare lunch ahead. Divide the cooled soup into individual containers so you have easy healthy lunches ready to reheat.

Storage and Meal Prep

Refrigerate leftover soup in airtight containers for up to 3–4 days. Reheat thoroughly on the stovetop or in the microwave, stirring occasionally.

For longer storage, freeze the soup in individual portions for up to 3 months for best quality. For the smoothest texture, add the Greek yogurt after reheating and thawing.
