Equipment
Method
- Add potatoes, onion, celery, and carrot to a 4-quart or larger soup pot.
- Pour in enough water to reach about 1/2 inch below the top of the vegetables.
- Bring to a boil over high heat, then reduce heat to low and cover.
- Simmer for about 20 minutes, stirring occasionally, until vegetables are soft and easily pierced with a fork.
- Carefully mash the soup using a potato masher to your preferred texture (chunky or smooth).
- Stir in milk and parsley (if using) until well combined.
- Season with salt and pepper to taste, adjusting as needed.
- Serve hot. Refrigerate leftovers in an airtight container for up to 3 days.
Notes
For a vegan version, use unsweetened almond or oat milk. Broth can replace water for deeper flavor. The soup naturally thickens after refrigeration—add more liquid when reheating. Top with shredded cheese, crispy bacon bits, fresh herbs, or a dollop of sour cream for extra indulgence.
