Method
Crisp the pancetta
- Cook the pancetta in a large pot until crispy, then remove and set aside.
- Keep the rendered fat in the pot so the onions sauté with flavor.
Build the roux and soup base
- Melt the butter in the same pot and sauté the onions for 8 minutes until soft and golden.
- Add the garlic and cook for 1 minute.
- Whisk in the flour and cook for 2 minutes.
- Gradually add the chicken broth and half-and-half, whisking constantly, until smooth and lump-free.
- Bring the mixture to a simmer.
Cook and finish
- Add the cubed Yukon gold potatoes and cook for 20 minutes until very tender.
- Mash about half the potatoes in the pot.
- Stir in the parmesan and sour cream until smooth and creamy.
- Season with kosher salt and black pepper.
- Serve topped with crispy pancetta, fresh chives, and extra parmesan.
Notes
For the smoothest texture, whisk the half-and-half and broth gradually into the flour mixture before bringing it to a simmer. Refrigerate leftovers in an airtight container up to 3 days; reheat gently on the stovetop with a splash of broth if needed (avoid aggressive boiling). Freezing is not recommended because the dairy can separate when thawed and reheated. For a lighter option, use low-fat half-and-half and reduce the parmesan slightly while keeping the sour cream.
