Method
Cook the pancetta
- Cook pancetta in a large pot over medium heat until crispy, about 6 to 8 minutes. Remove the pancetta and set it aside.
Build the base
- Melt butter in the same pot over medium heat. Sauté onions for 8 minutes until soft and golden.
- Add garlic and cook for 1 minute, stirring so it doesn’t brown. Whisk in flour and cook for 2 minutes.
Simmer and thicken
- Gradually add chicken broth and half-and-half while whisking constantly, until smooth. Bring the mixture to a simmer, 2 to 3 minutes.
- Add the cubed Yukon gold potatoes and simmer until very tender, 20 minutes. You should be able to pierce them easily with a fork.
- Mash about half the potatoes in the pot to thicken the soup. Stir in parmesan and sour cream until smooth and creamy.
- Season with kosher salt and black pepper, to taste, then stir to combine. Serve hot, topped with crispy pancetta, fresh chives, and extra parmesan.
Notes
For the creamiest texture, whisk the roux and dairy together until completely smooth before adding the potatoes. Store leftovers in an airtight container in the refrigerator for up to 4 days; reheat gently over low heat, since cream soups can tighten when boiled. Freezing is not recommended because the dairy may separate after thawing. If you want it lighter, substitute half-and-half with low-fat milk and add the parmesan last for best texture.
