Sweet Potato and Apple Soup

Ingredients

• 2 tablespoons olive oil
• 1 medium onion, chopped
• kosher salt and black pepper
• 2 pounds medium sweet potatoes (about 3), peeled and cut into 3/4-inch pieces
• 3 apples (such as Granny Smith or Pink Lady), 1 peeled and chopped and 2 thinly sliced
• 2 cups low-sodium vegetable broth
• pinch ground nutmeg
• 1 cup blue cheese, such as Gorgonzola or Stilton (4 ounces )
• 1/3 cup walnuts
• 16 crackers or crostini

Directions

1. Heat the oil in a large pot over medium heat. Add the onion, ½ teaspoon salt, and ¼ teaspoon pepper and cook, stirring occasionally, until tender, 6 to 8 minutes.
2. Add the sweet potatoes, chopped apple, broth, nutmeg, and 1½ cups water. Bring to simmer and cook, covered, until the potatoes are tender, 12 to 15 minutes.
3. Working in batches, transfer the mixture to a blender and puree until smooth, adding more water if necessary to reach the desired consistency. (Alternatively, use a handheld immersion blender in the pot.)
4. Serve the soup with the blue cheese, walnuts, crackers, and sliced apples.
