Method
- Melt the butter in a 5-quart Dutch oven over medium heat.
- Add the onion and celery and cook for 5 to 7 minutes, stirring occasionally, until softened.
- Stir in the flour and cook for 1 minute.
- Gradually whisk in the broth until smooth.
- Add the potatoes, salt, and pepper, and bring the soup to a boil.
- Reduce the heat to maintain a gentle simmer and cook uncovered for 15 to 20 minutes, stirring occasionally, until the potatoes are very tender.
- Mash some of the potatoes against the side of the pot to thicken the soup.
- Stir in the milk and heat gently for 3 to 5 minutes, without boiling, until hot.
Notes
For a thicker soup, mash more potatoes against the side of the pot. Refrigerate leftovers for up to 3 days; freezing is not recommended because the milk-based soup may separate. Use vegetable broth instead of chicken broth for a vegetarian version.
