Ingredients

  • 1 tablespoon olive oil
  • 1/2 sweet onion diced
  • 1 celery stalk diced
  • 2 teaspoons salt divided
  • 1 clove garlic minced
  • 1 1/4 pounds sweet potato peeled and cut into 1-inch chunks
  • 1 celeriac peeled and cut into small pieces
  • 1 apple peeled, cored, and cut into 1-inch chunks
  • 3 sprigs thyme tied tightly with kitchen twine
  • 4 cups vegetable broth low-sodium recommended
  • 1/2 cup dry white wine
  • 1/4 teaspoon ground white pepper
  • 1/2 cup heavy whipping cream optional
  • Pepitas or thyme leaves for garnish

Instructions

  1. Heat olive oil in a soup pot over medium heat. Add onion, celery, and 1/2 teaspoon salt. Cook until softened, stirring occasionally, about 5 minutes. Add garlic, stir, and cook for 1 minute.
  2. Add sweet potato, celeriac, apple, thyme, broth, wine, remaining salt, and pepper.
  3. Bring to a boil then reduce heat to simmer. Cover and cook until sweet potato and celeriac have softened, about 25 minutes. Remove and discard thyme sprigs.
  4. Working in batches, transfer soup to a blender and blend until smooth. Do not fill blender more than 2/3 full as hot liquids can expand when blending.
  5. Return blended soup to pot and stir in heavy cream (if using). Cook over low heat for 5 minutes.
  6. Garnish soup with pepitas or fresh thyme leaves.
