Irish Potato Soup Recipe

In a large saucepan, combine potatoes and enough water to cover. Bring to a boil over medium heat; cook until potatoes are tender, about 10 minutes.

While potatoes are cooking, spray a medium nonstick skillet with vegetable cooking spray. Heat skillet over medium heat. Add onion; cook, stirring frequently, until softened, about 5 minutes. Remove from heat.

Drain potatoes in a colander. Return potatoes to saucepan. Using a potato masher or a fork, mash potatoes until smooth. Stir in onion, milk, and celery salt. Cook, over medium heat, stirring constantly, until soup is smooth and heated through, about 5 minutes. (Do not boil.)

Ladle soup into bowls. Top with parsley sprigs and sprinkle with pepper. Serve immediately.
