Create a comforting and creamy potato and leek soup using a food processor and an air fryer. Start by slicing the potatoes and leeks using the slicing attachment of the food processor. In a pot, sauté the sliced leeks in butter until softened. Add the sliced potatoes, chicken or vegetable broth, and seasonings like thyme, salt, and pepper. Bring the mixture to a boil, then reduce the heat and simmer until the potatoes are tender. Once cooked, use the food processor to blend the soup until smooth and creamy. Preheat the air fryer to 375°F and pour the blended soup into the air fryer basket. Cook for about 10-12 minutes, stirring occasionally, until the soup is heated through. Serve hot and enjoy the comforting flavors of this potato and leek soup!
